RICHMOND, VA (WWBT) - Richmond International Airport will make a run at 100 degrees today — something we didn't do all last year. We did do it three time the summer before that. It was a notable early season heat wave June 7-10 of 2008. We hit 100 three of four days and set or tied three records.
For us to get to a record high, we typically need to be in the midst of a dry spell. Central Virginia has certainly been dry lately with RIC only recording 0.39" of rain so far this month. That's more than two inches below average.
A dry spell long enough to dry out the top layer of soil leaves little moisture left to evaporate. That evaporation helps cool us down. With low soil moisture, that evaporative cooling is limited.
That heat wave of early June, 2008? Similar in terms of meager rainfall in late May and early June.
Some rain would be much appreciated. To help the soil and to help keep us a little cooler.
