Dulles - from NWS Sterling (KLWX): " THE MAIN STORY THIS JULY WAS THE RECORD HEAT. THE FOLLOWING IS A COMPILATION OF SOME OF THE MANY RECORDS THAT WERE BROKEN AT DULLES THIS MONTH... JULY 2011 WAS THE HOTTEST JULY AND HOTTEST MONTH ON RECORD. THE MONTHLY AVERAGE TEMPERATURE OF 81.0F SMASHED THE PREVIOUS HOTTEST JULY/MONTH AVERAGE OF 79.7F SET IN JULY 1993. THE MAX TEMPERATURE AVERAGED 92.8F FOR THE MONTH...WHICH WAS THE HIGHEST MAX TEMPERATURE FOR JULY AND FOR ANY MONTH. THE PREVIOUS RECORD WAS 92.5F SET LAST JULY 2010. THE MIN TEMPERATURE AVERAGED 69.1F FOR THE MONTH...WHICH WAS THE SECOND WARMEST MIN TEMPERATURE FOR JULY...SECOND ONLY TO 69.4F IN JULY 1994.

Glen Allen - Lowell Koontz reports: " July was extremely hot again this year. The Richmond International Airport had a mean monthly average of 82.1°F which was only 0.7°F less than last year, which was the hottest July since temperature records were started in 1880. The July mean average temperature here was 81.5°F a +5.1°F departure when compared to Ashland's average. July's mean was only 0.5°F less this year when compared to last July. The 3.69 inches of rainfall for July at Glen Allen was a -0.66 inch departure when compared to Ashland's average. The Richmond International Airport had 3.63 inches and was the 47th driest from 1887 to 2011. July had 9 days with measurable rain with 1.71 inches or 46% of the month's rainfall occurring on the 8th. The Richmond International Airport had 1.72 inches on the 8th, which is now a new daily record amount there. At Glen Allen July had 22 days with 90°F or above temperatures the same as last year. The maximum temperature for July was 102°F recorded on July 22nd which is the second highest maximum temperature ever recorded here. But with the high relative humidity the heat index hit 117.6°F at 1358; this was higher than any reading last year. The Airport had 103°F on the 29th, which set a daily maximum temperature record for the date. They also set three daily high minimum temperature records on the 12th, 22nd, and 30th. The minimum temperature on the 12th was 81°F, which makes it the warmest night ever recorded for Richmond, Virginia. On 20 nights the minimum temperature was 70°F or higher at the Airport. A wind gust of 35 mph on the 3rd is thought to be the strongest wind gust recorded for July that occurred in a thunderstorm in which lightning hit within 50 feet of my weather station and destroyed the anemometer. (see pic with a click here) The other equipment damaged was a Davis transmitter module #6152 which included the sun, rain, wind, temperature and relative humidity. The wireless leaf and soil moisture/temperature transmitter #6345 and both leaf wetness sensors, solar radiation sensor, temperature/relative humidity sensor, intercom system were destroyed. It also damaged two thermometers that monitored soil temperature and leaf wetness sensor temperature. As of July 30th the Glen Allen Weather Station is back to full operation. [Editor's note: Lowell also included a spreadsheet of the changes in normals for Richmond (RIC) from 1980 to 2010. You can view his work here. " - [ + - ]
Herndon - Randy sends these additional notes: " July was above normal for temperature and precipitation. The temperatures ranged between a high of 100 and a low of 58. The average highs/lows were 4.5 and 1.8 degrees above normal, respectively. This was the hottest July that I have ever recorded at this location. On the precipitation side, the numbers were very misleading. The month was 0.38" above normal with 4.13" measured. However, we only had rain on five widely scattered days with three days accounting for 94% of the month's rain. The rest of the month was very dry. The heaviest rain (1.52") came on the 25th; for the year now we are 2.3" below normal. " - [ + + ]
