June climate highlightsJuly 16th, 2012 at 11:02 am by Natalie Stoll under Weather
But, June in Central Texas was a drier than normal one. We received only 0.o6″ of rain at Camp Mabry.
Here’s a roundup for June’s climate info from the NCDC:
- The average temperature for the contiguous U.S. during June was 71.2°F, which is 2.0°F above the 20th century average. The June temperatures contributed to a record-warm first half of the year and the warmest 12-month period the nation has experienced since recordkeeping began in 1895. Scorching temperatures during the second half of the month led many cities to set all-time temperature records.
- Precipitation totals across the country were mixed during June. The nation, as a whole, experienced its tenth driest June on record, with a nationally-averaged precipitation total of 2.27 inches, 0.62 inch below average. Record and near-record dry conditions were present across the Intermountain West, while Tropical Storm Debby dropped record precipitation across Florida.
- Warmer-than-average temperatures were anchored across the Intermountain West and much of the Great Plains during June. Colorado had its warmest June on record, with a statewide temperature 6.4°F above average. Seven additional states in the region had a top ten warm June.
- Cooler-than-average temperatures were present for the Pacific Northwest, where Washington had its seventh coolest June on record. Cooler-than-average conditions were also present for the Southeast, despite record warm temperatures towards the end of the month.
- Record-breaking temperatures occurred across a large portion of the nation during the second half of June. Over 170 all-time warm temperature records were broken or tied during the month. Temperatures in South Carolina (113°F) and Georgia (112°F) are currently under review by the U.S. State Climate Extremes Committee as possible all-time statewide temperature records.
- Precipitation patterns were mixed across the country. Drier-than-average conditions were present from the West, through the Plains, into the Ohio Valley and Mid-Atlantic. Wyoming had its driest June on record, with a precipitation total of 0.45 inch, which is 1.27 inches below average. Eleven additional states from Nevada to Kentucky had June precipitation totals ranking among their ten driest.
- According to the U.S. Drought Monitor, as of July 3, 56.0 percent of the contiguous U.S. experienced drought conditions, marking the largest percentage of the nation experiencing drought conditions in the 12-year record of the U.S. Drought Monitor. Drought conditions improved across Florida, due to the rains from Tropical Storm Debby. Drought conditions worsened across much of the West, Central Plains, and the Ohio Valley, causing significant impacts on agriculture in those regions.
- Tropical Storm Debby brought copious precipitation to Florida during June as it slowly traversed the state. Florida’s monthly statewide precipitation total of 13.16 inches was 6.17 inches above average, ranking as the wettest June on record for the state. Parts of the Northeast, as well as the Pacific Northwest, were wetter than average. Maine, Oregon, and Washington each had a top ten wet June.
- Several large wildfires raged across the West in June, destroying hundreds of homes and causing the evacuation of tens of thousands of residences. The very dry, warm, and windy weather created ideal wildfire conditions. Nationwide, wildfires scorched over 1.3 million acres, the second most on record during June.

- Climate Highlights — Year-to-Date (January-June)
- The January-June period was the warmest first half of any year on record for the contiguous United States. The national temperature of 52.9°F was 4.5°F above average. Most of the contiguous U.S. was record and near-record warm for the six-month period, except the Pacific Northwest. Twenty-eight states east of the Rockies were record warm and an additional 15 states were top ten warm.
- The first six months of 2012 were also drier than average for much of the contiguous U.S., with a nationally-averaged precipitation total 1.62 inches below average. Drier-than-average conditions stretched from the West, through the Central Plains, into the Ohio Valley and Mid-Atlantic. Fourteen states in total had precipitation totals for the six-month period among their ten driest.
- Wetter-than-average conditions were present for the Northwest and Upper Midwest, where Minnesota, Oregon, and Washington had six-month precipitation totals among their ten wettest.
- The U.S. Climate Extremes Index (USCEI), an index that tracks the highest and lowest 10 percent of extremes in temperature, precipitation, drought and tropical cyclones across the contiguous U.S., was a record-large 44 percent during the January-June period, over twice the average value. Extremes in warm daytime temperatures (83 percent) and warm nighttime temperatures (70 percent) covered large areas of the nation, contributing to the record high value.
- Climate Highlights — 12-month period (July 2011-June 2012)
- The July 2011-June 2012 period was the warmest 12-month period of any 12-months on record for the contiguous U.S., narrowly surpassing the record broken last month for the June 2011-May 2012 period by 0.05°F. The nationally-averaged temperature of 56.0°F was 3.2°F above the long term average. Every state across the contiguous U.S. had warmer than average temperatures for the period, except Washington, which was near normal.

- For the most part, June was a relatively average month where temperatures are concerned. Both Tennessee and Mississippi experienced a slightly cooler than normal month, while Louisiana and Arkansas experienced a slightly warmer than normal month. In these four states, temperature averages for the month typically fell within 2 degrees F (1.11degrees C) of normal. This was also the case for eastern Oklahoma and Eastern Texas, which experienced a slightly warmer than normal month. In western Texas and western Oklahoma, however; temperature departures were a bit higher, ranging from 2 to 6 degrees F (1.11 to 3.33 degrees C) above normal. One state ranking worth mentioning is for Texas, which experienced its thirteenth warmest June on record (1895-2012) with an average temperature of 82.40 degrees F (28.00 degrees C). The other state averages ranking outside of the top twenty five. Their averages are: 77.80 degrees F (25.44 degrees C) for Arkansas, 80.40 degrees F (26.89 degrees C) for Louisiana, 78.00 degrees F (25.56 degrees C) for Mississippi, 78.60 degrees F (25.89 degrees C) for Oklahoma, and 73.80 degrees F (23.22 degrees C) for Tennessee.
- With a few small exceptions, June was a relatively dry month with much of the region receiving less than average precipitation totals. The driest area of the region proved to be southern and south eastern Texas, where a majority of stations received only 0 to 25 percent of normal precipitation. This was also the case for much of central Tennessee, western Arkansas, north central Louisiana, and south central Mississippi. Average precipitation totals for all states were below the 1895-2012 average. For Tennessee, it was their sixth driest June on record (1895-2012). The average precipitation total for Tennessee was a mere 1.91 inches (48.51 mm). Arkansas received 2.02 inches (51.31 mm) of precipitation for the month, which was their seventeenth driest June on record (1895-2012). Other state precipitation totals include: Louisiana with 4.50 inches (114.30 mm), Mississippi with 3.25 inches (82.55 mm), Oklahoma with 2.75 inches (69.85 mm), and Texas with 2.00 inches (50.80 mm).
- With all six states receiving less than normal precipitation in June, drought conditions throughout the Southern Region have deteriorated. Much of Tennessee is now experiencing a severe (D2) drought. In Arkansas, conditions have worsened from moderate to severe drought, with pockets of extreme drought in all areas of the state. Central Texas has also been downgraded from no drought and moderate (D1) drought to moderate (D1) and severe drought (D2). In Louisiana, northern parishes are now experiencing moderate (D1) drought as well. This is also the case for eastern Tennessee and much of central and eastern Oklahoma.
- Texas farmers harvested their summer crops in early June, and they generally received a better yield than expected, even in West Texas where rain was scarce. Livestock was reported to be in fair condition as well, according to the Texas AgriLife Extension Service. Ranchers noted healthy grasslands provided food for cattle while the spring rains refilled stock tanks. However, the looming hot and dry summer conditions have begun to worry farmers and ranchers.

- In Texas, severe storms caused extensive damage across Texas during June. Towns in the Lower Rio Grande valley endured minor floods after strong storms dumped over 2.5 inches (63.50 mm) of rain in an hour. In the greater Houston area, there were several reports of tornados and supercells with lightning and strong winds. Those alone caused minimal damage, but accompanying hailstorms managed to cause several million dollars of damage in Houston. In the Dallas-Ft. Worth Metroplex, small but severe supercells produced baseball-sized hail over north Dallas during rush hour. After the damage had been assessed, officials estimated the cost of damages to be over $1.5 billion. Across much of the state, severe storms tormented cities during the first half of June.

- In Texas, extreme heat claimed its first life in the last week of June as temperatures climbed above 100 degrees F (37.78 degrees C); the middle-aged man died of a severe heat stroke. The high temperatures also caused numerous problems with roads and pipes across the state. (Information provided by the Texas State Climate Office)
- Three people were reported killed from a tornado in Crosby County, Texas. The twister touched down on June 4, 2012. It was reported to be of EF-2 strength.
- Storms on June 11, 2012 resulted in dozens of hail reports which spanned from Northern Arkansas and Northern Tennessee, to eastern Texas and as far south as southern Mississippi. Hail stone sizes varied from nickel to baseball size.
