August 2013 Statewide Temperature and Precipitation Rankings

August 2013 Climate Summary:

 Nebraska had near normal temperatures and near normal precipitation during  August 2013.  As has been the case all year there were contrasts across the lower 48 states.  The southeastern U.S. had below normal temperatures while the northwestern U.S. had above normal temperatures.  The precipitation rankings also exhibited extreme variability across the 48 states.  Note for example that Indiana had it 4th driest August on record, yet neighboring Kentucky had above normal precipitation.  Minnesota and Iowa had their 7th driest August precipitation on record yet nearby Kansas had its 8th wettest August and South Dakota had well above normal  precipitation in August 2013.

 Here is a summary from our partners NOAA; NCDC and HPRCC.

Climate Highlights — August 2013
  • The average temperature for the contiguous U.S. during August was 73.1°F, 1.0°F above the 20th century average — the 28th warmest such month on record.
  • The western U.S., particularly the Northwest, was warmer than average during August. Idaho had its second warmest August, with a monthly temperature of 69.4°F, 4.5°F above average. Wyoming tied its third warmest August, with a temperature of 67.8°F, 3.7°F above average.
  • Below-average temperatures stretched from the Central Plains, through the Ohio Valley, and along most of the Eastern Seaboard, but no state had August temperatures ranking among the ten coolest.
  • The nationally-averaged August precipitation total of 2.63 inches was 0.03 inch above average.
  • Both wet and dry extremes were experienced across the contiguous U.S. during August, resulting in a near-average national precipitation total for the month. California, Georgia, and Kansas each experienced a top ten wet August, while Illinois, Indiana, Iowa, and Minnesota each had a top ten dry month.
  • According to the September 3rd U.S. Drought Monitor report, 50.1 percent of the contiguous U.S experienced drought conditions, up 4.5 percent since the end of July. Drought conditions expanded into the Upper Midwest and Lower Mississippi River Valley, as well as Hawaii. Beneficial rainfall helped to improve, but not eliminate, drought conditions across the Central and Southern Plains.
  • On a local basis, the number of record warm daily highs and lows (about 1800) during August was slightly greater than the number of record cool daily highs and lows (about 1450).
