…..Also, we have officially run out of fans and have a waiting list. I believe that it’s been because of the cooler summer, which is deceptive, but doesn’t mean that families need fewer fans. We keep getting people who send us messages like, “I usually give $100, but since it’s been a cool summer we’re only donating $30 this year.” We’re making a big push through our social media and eblasts to see if we can’t get some more fans or funds, but wanted to see if you could also mention it on the air? Our warehouse is literally empty except for five desk fans! We are going to try to run over to Home Depot to get what they have on the shelves, but we’d like to be able to place a large order to be able to get through one of the hottest months, August. Thank you!

Late July chill setting record lows – cold front headed here

July 30th, 2014 at 2:34 pm by under Weather

We are not expecting record lows here in Central Texas, but we will get a taste of the unusually nice summer temperatures being reported in the East today. The cold front bringing record lows there will arrive here Thursday.

(Climate Central) Folks across the eastern U.S. could be forgiven for thinking they’d pulled a Rip van Winkle and woken up in October on Wednesday morning. Temperatures dipped down overnight into the 60s, 50s and even 40s, setting record lows left and right.

The chill in the air comes courtesy of yet another bout of cool Canadian air that dipped down over the area east of the Rockies earlier this week, creating decidedly un-summerlike temperatures at what is normally the hottest time of the year for many locations and spurring some severe weather, including a rare Boston-area tornado.

“We’re in the heart of that hottest normal time of the year and it’s anything but that,” Bruce Terry, lead forecaster for the National Weather Service, told Climate Central on Monday.

The cool conditions in the East contrasted, as they have nearly all year, with baking conditions in the West, which have exacerbated the effects of California’s epic drought and helped fuel wildfires. This temperature pattern is occurring over a background warming fueled by the accumulation of greenhouse gases in Earth’s atmosphere that are making record lows overall less likely and record highs more common. The pattern the U.S. has seen is also one scientists say could be more common in a warming world.

Numerous National Weather Service offices and other local meteorologists took to Twitter and other media to note the astonishing thermometer readings across the East: Nashville tied its record low for July 30 of 58°F (originally set in 1965), according to the local NWS office. Dulles International Airport in Washington, D.C. dropped to an incredible 48°F, shattering the record low of 51°F set in 1981, while Baltimore’s airport hit 55°F, just beating the record of 56°F set in 1997, the Capital Weather Gang reported.

Other July 30 records included: 59°F at Atlanta Hartsfield-Jackson International Airport, beating the previous record of 61°F set in 1936; 59°F in Birmingham and Montgomery, Ala.; and 51°F in Pittsburgh, where the previous record of 52°F was set in 1982.

In contrast, cities on the West Coast have been sweltering. San Francisco is set to see its warmest July on record and even hit an uncharacteristic 90°F on July 25, a full 12°F above normal, Dennis Mersereau at The Vane wrote. Portland, Ore., hit an even more sizzling 99°F this month and is on track for its sixth warmest July.

The pattern behind this stark temperature divide is one in which large waves in the jet stream send a deep trough, or area of low pressure in the atmosphere, diving down over the East, while a ridge, or high pressure area, parks itself over the West. The same pattern was in play earlier in July and during much of the winter months and into spring.

While the winter and spring events were linked to an incursion of the polar vortex — an upper-level atmospheric feature of cold, low-pressure air surrounded by strong winds that circle the pole ­— southward, the National Weather Service has been reluctant to link the summer cold spells to the same cause. Other meteorologists, however, have said that the events do indeed have a polar component.

Why the country keeps seeing this particular pattern this year, forecasters can’t say.

“I don’t know why we keep seeing it, but we do keep seeing it,” Terry said.

Jake Crouch, a climatologist with the National Climatic Data Center who helps conduct monthly investigations of major climate events in the U.S., said in an email that his team will likely do a detailed analysis of the July event to be released with next month’s update.

The pattern has affected the overall average temperatures of the U.S. in 2014, with the first four months of the year ranking as the coldest since 1993, according to the most recent State of the Climate update from the National Oceanic and Atmospheric Administration. But the warmth in the West — where California has recorded its hottest first six months to a year ever — has balanced out the cold, putting the year as a whole in the middle of the pack for temperature records going back a little more than a century.

And the situation in the U.S. is only one part of the globe, which just experienced its hottest May and June on record. The year to-date for the planet ranks as the fifth warmest.

As the world heats up because of the increasing concentrations of carbon dioxide put into the atmosphere by humans, the building warmth actually stacks the deck for record highs and against record lows, meaning the record lows seen across the East this week will be increasingly less likely to occur.

Super-close views of Mercury

July 29th, 2014 at 2:44 pm by under Weather


The MESSENGER spacecraft is now dropping closer to Mercury, and long anticipated, super-close views of the planet are beginning to come in.

Image via NASA / JHU / APL MESSENGER spacecraft

Close image of Mercury acquired by the MESSENGER spacecraft on June 11, 2014. 69.84 degrees North & 48.47 degrees East. Resolution 2.9 meters. Image via NASA / JHU / APL MESSENGER spacecraft

The image above is one of the highest resolution images ever returned of Mercury. MESSENGER acquired it on June 11, 2014. Last Friday – July 25, 2014 – MESSENGER’s periherm (closest point to Mercury) dropped below 100 kilometers / 62 miles. MESSSENGER is the first manmade object ever to come this close to Mercury.

On June 17 – around the time the image above was taken – the periherm had dropped to 113.80 kilometers / 70.80 miles. The image has absolutely incredible 2.90-meter resolution, showing a cluster of tiny secondary craters within the northern intercrater lava plains in a 3.00 kilometer / 1.86 mile wide area within Mercury’s North Polar Borealis Quadrangle.

The craters seen here are a few hundred meters at most in width, many much smaller. These are secondary craters from an impact out of this frame, where impact ejecta fell back on ballistic trajectories forming smaller craters. Many can be hundreds of kilometers away from the primary impact if the impact was large enough.

There are a handful of much smaller craters in the area too.

All of these craters in this image are of the simple bowl shaped type.

The image is a little ‘noisy’ due to the very short exposure required to prevent blurring of the image as MESSENGER was lower and faster than usual above the surface of Mercury.

On August 19, 2014, periherm will drop below 50 kilometers / 31 miles. On September 12, 2014, periherm will have lowered to 25 kilometers / 15.52 miles.

The number of such high resolution and even higher resolution images will increase as periherm continues to lower.

The fuel on board MESSENGER is expected to be depleted on January 21, 2015. MESSENGER is expected to impact Mercury during the last weekend of March, 2015.

How a solar storm two years ago nearly caused a catastrophe on Earth

July 26th, 2014 at 9:20 am by under Weather

By Jason Samenow:

CME captured by NASA July 23, 2012 (NASA)

On July 23, 2012, the sun unleashed two massive clouds of plasma that barely missed a catastrophic encounter with the Earth’s atmosphere.  These plasma clouds, known as coronal mass ejections (CMEs), comprised a solar storm thought to be the most powerful in at least 150 years.

“If it had hit, we would still be picking up the pieces,” physicist Daniel Baker of the University of Colorado tells NASA.

Via NASA: “This movie shows a coronal mass ejection (CME) on the sun from July 22, 2012 at 10:00 p.m. EDT until 2 a.m. on July 23 as captured by NASA’s Solar Terrestrial RElations Observatory-Ahead (STEREO-A). Because the CME headed in STEREO-A’s direction, it appears like a giant halo around the sun. NOTE: This video loops 3 times.” Credit: NASA/STEREO

Fortunately, the blast site of the CMEs was not directed at Earth.  Had this event occurred a week earlier when the point of eruption was Earth-facing, a potentially disastrous outcome would have unfolded.

“I have come away from our recent studies more convinced than ever that Earth and its inhabitants were incredibly fortunate that the 2012 eruption happened when it did,” Baker tells NASA.  “If the eruption had occurred only one week earlier, Earth would have been in the line of fire.

A CME double whammy of this potency striking Earth would likely cripple satellite communications and could severely damage the power grid.  NASA offers this sobering assessment:

Analysts believe that a direct hit … could cause widespread power blackouts, disabling everything that plugs into a wall socket.  Most people wouldn’t even be able to flush their toilet because urban water supplies largely rely on electric pumps.

. . .

According to a study by the National Academy of Sciences, the total economic impact could exceed $2 trillion or 20 times greater than the costs of a Hurricane Katrina. Multi-ton transformers damaged by such a storm might take years to repair.

CWG’s Steve Tracton put it this way in his frightening overview of the risks of a severe solar storm: “The consequences could be devastating for commerce, transportation, agriculture and food stocks, fuel and water supplies, human health and medical facilities, national security, and daily life in general.”

Checkup says earth is running a temperature

July 22nd, 2014 at 1:54 pm by under Weather


(Climate Central) Looking at the state of the climate, you can see heat everywhere. From the top of the globe to the depths of the oceans and everywhere in between, the climate is warming and changing in ways humans have never experienced.

Last year was between the globe’s third- and sixth-warmest year on record, including record heat in Australia. The frequency of hot days in 2013 was also among the top 10 years while cold nights were among the bottom 10 years. And heat content in the upper ocean reached record highs as did sea levels.

A map showing global surface temperature anomalies averaged over 2013 compared to 1981-2010 average.

Those changes and more are chronicled in a new report published on Thursday in the Bulletin of the American Meteorological Society. This is the 24th straight year of the report, which amounts to a global health checkup. Except in this case, instead of one doctor doing the exam, it was 425 scientists from 57 countries around the globe contributing to the nearly 260-page report.

It’s a massive undertaking to synthesize global climate data, which is why the report takes so long to put together and release.

“The take-home message here is that the planet — its state of the climate — is changing more rapidly in today’s world than at any time in modern civilization,” said Tom Karl, director of NOAA’s National Climatic Data Center, in a call with reporters.

The global average temperature, which is a broad baseline used to measure the climate, was about 0.4°F above average according to four datasets most commonly used by scientists. That was high enough to rank 2013 as up to the third-warmest year since 1880. All 10 of the warmest years have come since, with 2010 topping the charts.

Global hot spots for 2013 included parts of Russia and Eastern Europe, as well as Australia and Northern Africa. One of the only land areas with cooler-than-normal temperatures was the eastern half of North America.

The frequency of hot days is another indicator of the world’s continued warm streak. Last year was also in top 10 territory, driven in part by the extremes in Australia and Europe. In contrast, cool nights were in shorter supply, with 2013 ranking in the bottom 10 years.

A map showing ocean heat content anomalies averaged over 2013 compared to 1993-2013 average.

Ocean surface temperatures in 2013 were also among the top 10 warmest. But more notable is the amount of heat stashed in the upper half mile of the ocean, which has increased steadily and reached a record high in 2013.

“Warming in the upper (up to 700 meters) oceans accounts for about 63 percent of the total increase in energy storage in the climate system from 1971 to 2010,” the report said.

Scientists have posited that the apparent “pause” in global warming is being driven by increased heat storage in this layer of the ocean. Ocean warming coupled with melting ice has contributed to sea level rise, which also reached record highs in 2013.

Arctic sea ice extent, glaciers and late spring snow cover all felt the heat last year as well. Each continued a trend in line with the impacts of climate change.

The other notable record, and one which connects the dots between a number of the trends outlined in the report, is atmospheric carbon dioxide. Levels of CO2 and other greenhouse gases that are helping drive climate change were at record highs in 2013. CO2 crossed a notable milestone, hitting 400 parts per million for the first time in human history. Of course, 2014 is on track to smash the records set in 2013, with CO2 levels spending 3 months above the 400 ppm threshold.

Beyond global trends, the year was marked by regional extremes. Australia had its hottest year on record and parts of China experienced record summer warmth. However, the biggest single weather event of the year was Super Typhoon Haiyan, which killed more than 6,000 and left 2 million homeless.

At its peak, sustained winds from the storm reached 196 mph, which is 15 mph faster than the previous record according to James Renwick, a climate scientist at the New Zealand Climate Change Center (Renwick also edited one of the chapters of the new report). Haiyan’s storm surge did most of the damage. Scientists are still assessing just how high it rose but estimates put it in the  range of 24 feet.

While the connection between the rapid intensification and strength of Haiyan with climate change is still being studied, sea level rise represents a more direct climate change link. The Philippines have seen as much as 7 inches of sea level rise since 1970. To put that in perspective, the planet as a whole has seen 8 inches of sea level rise since 1900.

“Sea level rise is much higher than the global average in this part of the world, so the sea’s are already a little higher. If you put a storm surge on top of higher sea level, it amounts to a greater extent of coastal inundation.” Renwick said.

With 2014 halfway over, there are no signs that the globe’s hot streak is ending. Data through May shows that this has been the planet’s fifth-warmest start to the year on record. Jessica Blunden, a scientist who works with NCDC, said that preliminary data show that June’s ocean temperatures were the hottest on record, a sign that 2014 is  on track to be one of the hottest years recorded. Another factor tipping the scales in that direction is the impending El Niño, a climate phenomenon that usually boosts global temperatures. Other indicators like greenhouse gas emissions, Arctic sea ice and deep ocean heat are also likely to keep following suit.

Forecasters to test experimental lightning data

July 21st, 2014 at 1:39 pm by under Weather

Screen Shot 2014-05-15 at 10.48.39 AM

(NSSL)  NOAA National Weather Service (NWS) forecasters will test how lightning data impacts the warning process during convective events in the NOAA Hazardous Weather Testbed from July 21-August 29. The project is a collaboration between NSSL and Earth Networks, Inc., a private weather company.

Earth Networks has indicated the potential for its continental scale total lightning network (ENTLN) data and associated “Dangerous Thunderstorm Alerts” (DTAs) to increase forecaster situational awareness and lead times. Prior limited studies have shown the use of total lightning detections and associated derivative products could have positive impacts on the warning process.

During the tests, Earth Networks lightning data and its DTA products will be implemented into NWS operational software (AWIPS2) in the NOAA Hazardous Weather Testbed. Forecasters will complete a series of weather-warning scenarios in displaced real time, ranging from marginally severe to high-impact tornadic events for a variety of geographic locations.

These tests will evaluate the feasibility of using this data in warning operations, as well as the impact on warnings issued by NWS forecasters. The final outcome of this project is to make recommendations on possible product improvements, and determine whether Earth Networks products should become part of the operational product suites available to NWS offices nationally.

Beating The Heat: Safety Tips

July 21st, 2014 at 7:29 am by under Weather


If you plan on being out and about in summer, chances are you’ll be exposed to a lot of sun and higher temperatures.

Each year, heat kills at least 650 people on average in the United States — more than tornadoes, hurricanes, floods, lightning, or any other weather event combined.

“Heat can be a silent killer because it doesn’t topple trees or rip roofs off houses like tornadoes and hurricanes,” says Eli Jacks, chief of fire and public weather services with NOAA’s National Weather Service. “Nevertheless, it’s a dangerous weather condition for which people should prepare.”

How much heat can a person safely endure? It depends.

Certain groups of people should be especially careful during hot weather conditions. For example, city-dwellers and those living in the upper floors of tall buildings or in heat-prone regions are most at-risk for heat-related illness. People who have difficulty getting around or who have health conditions are particularly susceptible. The elderly and the very young also merit special attention during periods of high heat and humidity.

The National Weather Service and the  Occupational Safety and Health Administration have partnered again this year to increase awareness for outdoor workers and their employers during excessive heat events.  As part of this effort, the National Weather Service will incorporate specific outdoor worker safety precautions when heat advisories and warnings are issued.



By taking some precautions, you can stay healthy while enjoying the great outdoors this summer:

1. Be informed and stay alert

Pay close attention to heat advisories or warnings that have been issued for your community.

  • NOAA’s National Weather Service continually updates heat-related advisories and warnings online at (Click on “Excessive Heat Warning” and “Heat Advisory” under the U.S. map — if there are no current warnings or advisories in the United States, nothing will appear).
  • NOAA issues excessive heat warnings when weather conditions pose an imminent threat to life andheat advisories when weather conditions are expected to cause significant discomfort or inconvenience or — if caution is not taken — become life threatening.
  • If you do not have Internet access, you can get heat advisory and warning information by watching your local television or radio newscast or by purchasing a NOAA weather radio and tuning into NOAA Weather Radio All-Hazards.
  • Use the temperature and humidity to figure out the heat index for your area, a measure that tells us how hot it feels.

2. Plan for periods of extreme heat

  • Visit your physician for a check-up to find out if you have a health condition that may be exacerbated by hot weather.
  • Service your air conditioner before hot weather arrives, and obtain window fans to help cool your home.
  • Know where to go when weather heats up. Find cool indoor places to spend time on hot summer days, such as a local library, shopping mall, museum or aquarium.

3. Know what to do and what not to do during hot weather

  • DO - Slow down, and reduce strenuous activity. Mow the lawn or garden in the early morning or late evening instead of midday.
  • DO - Dress in lightweight, nonrestrictive, light-colored clothing.
  • DO - Drink plenty of water or other nonalcoholic fluids.
  • DO - Eat light, easy-to-digest foods.
  • DO - Seek out shade if you have to be outdoors for extended periods. Spend more time in air-conditioned places.
  • DO - Check on elderly neighbors, friends and relatives to make sure they are okay.
  • DO - When outside, take frequent dips in the ocean or pool, or mist yourself with a water bottle. When inside, take frequent cool baths or showers and use cold compresses to cool off.
  • DO - Apply high-SPF sunscreen frequently when outdoors.
  • DO - Seek immediate medical attention if you experience symptoms of heat illness. (See chart below for symptoms, likely conditions and treatment.)

keep calm

However, please remember:

  • DO NOT leave children, the elderly, or pets in the car for any reason, for any length of time. A dark dashboard or seat can easily reach temperatures in the range of 180 to more than 200 degrees F!
  • DO NOT stay in the sun for long periods.
  • DO NOT take salt tablets unless directed by a physician.
  • AVOID alcoholic beverages; they can dehydrate you and increase your risk of heat stroke and other potentially fatal heat-related illnesses.

4. Know the warning signs of heat-related illness

Excessive heat exposure can raise your body temperature to unhealthy levels and may make you ill — it can also be deadly. Take the precautions listed above and be on the lookout for these warning signs that you may be in trouble:

Symptom Likely Condition Treatment
Painful muscle cramps and spasms, usually in muscles of legs and abdomen. Heavy sweating. Heat cramps Apply firm pressure on cramping muscles or gently massage to relieve spasm.

Give sips of water; if nausea occurs, discontinue water intake.

Consult with a clinician or physician if individual has fluid restrictions (e.g., dialysis patients).

Heavy sweating, weakness,
cool skin, pale and clammy. Weak pulse. Normal temperature possible. Possible muscle cramps, dizziness, fainting, nausea and vomiting.
Heat exhaustion Move individual out of sun, lay him or her down, and loosen clothing.

Apply cool, wet cloths.

Fan or move individual to air conditioned room.

Give sips of water; if nausea occurs, discontinue water intake.

If vomiting continues, seek immediate medical attention. Consult with a clinician or physician if individual has fluid restrictions (e.g., dialysis patients).

Altered mental state. Possible throbbing headache, confusion, nausea and dizziness. High body temperature (106°F or higher). Rapid and strong pulse. Possible unconsciousness. Skin may be hot and dry, or patient may be sweating. Sweating likely especially if patient was previously involved in vigorous activity. Heat stroke Heat stroke is a severe medical emergency.

Summon emergency medical assistance or get the individual to a hospital immediately.

Delay can be fatal.

Move individual to a cooler, preferably air-conditioned, environment.

Reduce body temperature with a water mister and fan or sponging.

Use air conditioners. Use fans if heat index temperatures are below the high 90s. Use extreme caution.

Remove clothing. If temperature rises again, repeat process. Do not give fluids.
