Two freezing nights on the way

November 16th, 2014 at 9:40 am by under Weather

A powerful Arctic cold front is blowing through Central Texas today, bringing the return of very cold temperatures.

Mon lowsTues lows

Forecast lows Monday and Tuesday mornings indicate some patchy freezing temperatures tonight, then a widespread hard freeze Monday night.

Be sure to protect petspipesplants and people (check on the elderly and those without reliable heating systems).

High temperatures will finally warm to above-average readings in the 70s by the end of the coming work week. Stay warm out there!


205,000 families still homeless one year after Super Typhoon Haiyan

(Straits Times, Asia): Defending his government against criticism that it is moving too slowly in rebuilding communities ravaged by a super typhoon exactly one year ago, President Benigno Aquino appealed for patience, saying reconstruction takes time.

“I am impatient like everyone else, but I have to stress that we can’t rebuild haphazardly,” Mr Aquino said in a speech yesterday during a stop in the hard-hit town of Guiuan in Leyte province, where Haiyan first made landfall.

“Curse me, criticise me, but I believe I must do the right thing.”

Haiyan, the strongest typhoon to make landfall in recorded history, left a trail of destruction and some 6,300 deaths across central Philippines.

Mr Aquino has come under fire for having very little to show since Haiyan devastated communities in 171 cities and towns.

By his government’s own estimate, 205,128 families are still living in bunkhouses, tents and shanties in “unsafe areas”.

However, only 1,252 houses have been built for them.

Ex-Super Typhoon Nuri “bombs” in the Pacific

November 9th, 2014 at 5:48 pm by under Weather

What was once a 180-mph category 5 “super typhoon” in the Pacific has transitioned into an “extratropical” storm over the Bering Sea near Alaska. But as Dr. Jeff Masters explains, it hasn’t lost much strength:

(wunderground.com)

What was once Category 5 Super Typhoon Nuri bombed into one of the strongest extratropical storms ever observed in the Pacific Ocean, reaching 924 mb at 06 UTC Saturday morning–a pressure rarely achieved by an extratropical storm. Tonight, the storm is bringing 96-mph wind gusts to islands on the southwestern fringes of Alaska.

The only two Pacific storms I am aware of that compare are the October 25 – 26, 1977 storm near Dutch Harbor, Alaska that set Alaska’s all-time low pressure record (925 mb), and a storm from December 24, 1975 that hit 926 mb near 49°N 158°W. Wunderground’s weather historian Christopher C. Burt has all the details in his latest post. Thanks go to wunderblogger Steve Gregory for supplying the images below.

U.N. Report: Climate Change Dangers are ‘Higher than Ever’

November 2nd, 2014 at 1:08 pm by under Weather

Pollution and climate change due to human influence is “clear,” and the observed effects are “unprecedented,” according to a report released Sunday by a United Nations panel.

The 116-page report is the fifth since 1990 prepared by the Intergovernmental Panel on Climate Change (IPCC). The latest installment synthesizes the findings of the previous four reports and presents new conclusions that environmental scientists arrived at since the fourth report was released in 2007.

Halloween evening forecast

October 31st, 2014 at 10:53 am by under Weather

10-31 halloween

 

Temperatures will fall quickly after sunset Friday evening as the coldest air we’ve seen since mid-April moves into the area.

Trick-or-treaters will need a light jacket–especially long after sundown–as temperatures tonight fall into the 50s area wide this evening. Morning lows Saturday will fall into the 30s and 40s, which are the coldest temperatures we have seen in 6 1/2 months.

Happy Halloween!


Earth headed for its hottest year on record

Figure 1. Departure of temperature from average for September 2014, the warmest September for the globe since record keeping began in 1880. Record warmth was notable in much of northwestern Africa, coastal regions of southeastern South America, southwestern Australia, parts of the Middle East, and regions of southeastern Asia. In total, 31 countries and territories from all seven continents around the world had at least one station that reported record warmth. Cooler than average temperatures were uncommon world-wide. Image credit: National Climatic Data Center (NCDC) .

September 2014 was Earth’s warmest September on record, the period January – September was tied with 1998 and 2010 as the warmest first three-quarters of any year on record, and the past 12 months–October 2013 through September 2014–was the warmest consecutive 12-month period among all months since records began in 1880, said NOAA’s National Climatic Data Center (NCDC) today. NASAalso rated September 2014 as the warmest September on record. If 2014 maintains the same temperature departure from average for the remainder of the year as was observed during January – September, it will be the warmest calendar year on record. September is the fourth time NOAA has ranked a 2014 month as the warmest on record; May, June, and August 2014 were also the warmest such months on record. (April 2014 was originally ranked as tied for warmest April on record, but has since been revised downwards to the second warmest April on record.) Global ocean temperatures during September 2014 were the warmest on record, and the 0.66°C (1.19°F) ocean temperature anomaly was the highest ever measured, beating the record set just the month previously in August 2014. Global land temperatures in September 2014 were the 6th warmest on record. Global satellite-measured temperatures in September 2014 for the lowest 8 km of the atmosphere were the 14th or 7th warmest in the 36-year record, according to Remote Sensing Systems and the University of Alabama Huntsville (UAH), respectively.


If the climate is warming, why is Antarctic ice expanding?

October 19th, 2014 at 9:27 am by under Weather

The planet as a whole is doing what was expected in terms of warming. Sea ice as a whole is decreasing as expected …’

Sea ice is expanding around Antarctica, and scientists say wind, snow and melting land ice are key factors in the growth bberwyn photo.

The map at right shows Antarctic ice concentration on September 22, 2014, the date of the record high. Areas where the surface was less than 15% ice covered are deep blue; areas that were up to 100% ice covered are shades of light blue to white. The orange line shows the 1981-2010 median extent for September 22. (Median means in the middle: half of the years in the record had smaller ice extents than this, and half had larger extents.) The graph below the map shows daily Antarctic sea ice extent over the course of the year. The black line traces the 1981-2010 average, and the gray shading shows the range of variability (2 standard deviations from the mean). The previous record high extent (2013) is a dashed green line; the 2014 year to date is a light green line. NSIDC reported that the 2014 extent rose nearly 4 standard deviations above the 1981-2010 mean.

FRISCO — Along with shifting wind patterns in the southern hemisphere, melting land ice may be contributing to recent record extents of floating sea ice around Antarctica. The melting ice and snow adds fresh water — which freezes morel easily — to the salty Southern Ocean, scientists said in a release this week, explaining the multi-year trend of expanding Antarctic sea ice.
