    Glen Allen - Lowell adds: " February was much warmer than average as the monthly mean temperature was 44.3F, a +3.7F departure. As warm as February has been at the Glen Allen Station, it is surprising that last February was a little warmer. There were 18 days the minimum temperature dropped below freezing and 0 days that the maximum didn't climb above freezing. The 3.36 inches of rain for February was a +1.32 inch departure when compared to the three year average. February of 2011 had a -1.47 inch deficit in precipitation. The maximum rainfall recorded in a day was 1.38 inches on the 29th which was the greatest daily rainfall since December 7, 2011. Measurable precipitation occurred on 13 days but was light except for the 19th and 29th when 66% of the month's precipitation occurred. The total frozen precipitation was 5.2 inches for the month recorded on the 11th, 19th, 20th giving a negative 0.2 inch departure. The 0.5 inch snow on the 11th was associated with a thunder snow from the passage of a strong cold front. It was Glen Allen's first thunder snow. (Records since August 2008) The maximum temperature for February was 81F on the 24th and the Richmond International Airport also had 81F which was only 2F from the highest temperature on record since 1897 for February. There have been only four days in Richmond's recorded history with higher temperatures. (daily records since 1897) The lowest minimum this month at West Henrico Co. - Glen Allen was 18F recorded on the 12th and 13th. The maximum wind gust was 46 mph from the south that occurred on Feb. 24th at 1503 hours. This occurred in a thundershower preceding a cold frontal passage and was the strongest wind since Irene on August 27th, 2011 and set a new record wind speed for February. The highest barometer recorded for the month was 30.52 inches on the 3rd and the lowest was 29.33 inches on the 24th. The winter has been very mild as December was the 8th warmest, January was the 20th warmest, and February tied for the 16th warmest month since 1881. The winter tied for the fourth warmest winter since the beginning of mean temperature records in 1881.
