We talked about it here on the Weather Insider earlier and now it's official: May 2015 was one of the warmest Mays on record in Richmond. It tied with May 1953 with an average temperature of 71.5. Our historical average temperature for May is 66.4, so this May was just over five degrees above average.
A big reason it was so warm was because it was dry. Only 1.61 inches of rain was recorded at Richmond International Airport the entire month, 2.17 inches below average. The lack of cloudy, wet days along with drier soil allowed for temperatures to soar. We had highs of 90 or warmer five times in a month when our average highs typically run in the upper 70s.
Does this mean we're in for an extra hot summer? Not necessarily. While long range models are indicating that June could end up being warmer than average as well, there are no strong signals indicating this pattern will last. While El Nino often leads to less active hurricane seasons, its impacts on the rest of our summer weather are variable.
If this summer does end up being warmer than average, we're well prepared after this May!
