I came across this handy document by the NWS yesterday that displays the top 10 snow events, by month, for Richmond, Virginia. The document is located here.
Days With High Temps Above Avg: 17
Days With Low Temps Above Avg: 11
Highest Temp: 72.1 on 2/23
Lowest Temp: 14.7 on 2/13
Mean Temp thru the 23rd: 42.8
Snow: 3.9″ on 2/18 (RIC only had a trace before this)
I got an interesting email from Larry at the NWS Wakefield office about Richmond historical winter snow totals. See the email below:
“We have recorded at trace of snow thus far this season at Richmond (the only season that finished with just a trace is 1918-19). The 2nd lowest amount in a season was 0.5” in 1944-45. For “seasonal snowfall” the entire season is considered so we will need to have no measurable snow for Feb, Mar, Apr this year to tie the 1918-19 season. Recently in 2006-07, we had just 0.3″ by the end of March…appeared to be set to have the 2nd lowest snowfall season on record…until Easter Sunday in April recorded 1.0″ making the seasonal total 1.3″…9th lowest.”
Very interesting.

This am it got down to 26.1*. Good to see lows starting to dip into the mid 20’s. RIC reached 29*, the first sub-30* of the season.

Church Hill: 3.36″
One impressive statistic from the 2010 weather data that was recorded at my house was the highest amount of liquid rainfall accumulating in a 24-hour period. Signaling the end of summer and an extreme drought, my station recorded 3.36″ of rain in a single day. The radar loop from the day is impressive as well. The rain was spawned from the remnants of Nicole and a coastal low.
