Abnormally strong high pressure centered over eastern Canada has formed a very determined cold air damming wedge across the Virginia Piedmont. In addition, an upper level trough over the Ohio Valley is pumping moist air up and over that surface wedge via southwesterly upper air winds. The result is a cool, overcast, and rainy Wednesday across Mecklenburg County.
As of this writing local rain gauges have recorded 1.17", 2.71", 1.52", and 1.75" at South Hill, Boydton, Chase City, and Clarksville respectively. Those totals will increase over the next 72 hours as illustrated in this NWS Wakefield forecast graphic:
Folks should be aware of water ponding on roads and possible localized flooding during the heaviest rain periods.
Thursday then looks to continue the damp trend, but the rain will taper off to occasional showers. Skies will remain cloudy much of the day, with perhaps a couple late afternoon breaks in the overcast allowing a glimpse of the sunset. Temperatures tomorrow afternoon will top out in the lower 70s.
At this point the weekend appears to be drier and warmer. Friday's blogpost will take a closer look at those conditions.
