Tropical humidity and plenty of rain

As of this writing Mecklenburg County has only been brushed by the heavy rains which have inundated areas closer to the mountains with 3+ inches of liquid. Since the precipitation began local rain gauges have collected 0.56", 0.94", 1.13", and 1.33" at Clarksville, Chase City, Boydton, and South Hill respectively. More is on the way per this NWS Wakefield forecast graphic:

Additionally, this Wednesday morning's temperatures and dew points equal each other in the low 60s, giving rise to plenty of fog around the county. Visibilities have dwindled to a quarter-mile or less in a number of areas, so be careful when on the roads. 

This sogginess is all due to a slowly weakening upper level low pressure system which is circulating over the Midwestern states this morning. The counterclockwise air flow around that feature has been pumping moisture northward into the area. A  warm front extending from a surface low pressure center over North Carolina is parked just north of the county.

Showers will re-enter the picture later this morning, with thunderstorms likely this afternoon. The Storm Prediction Center has issued a Marginal Risk - level 1 of 5 - for severe storms today. Any peeks of sunshine will provide the juice to intensify those storms, with the main threats (besides lightning and heavy downpours) will be strong straight line winds and hail. Today's high temperatures will top out in the upper 70s.

Thursday looks to be somewhat drier, although the county is under another Marginal Risk of severe weather. Overcast skies will begin the day, but by lunchtime sunshine will reappear. That, of course, will help fire up thunderstorms during the late afternoon given the continued juicy air. Temperatures tomorrow will rise from morning lows near 60º to afternoon highs in the mid-80s. 

The weekend looks somewhat drier, with daily highs continuing in the 80s. Keep that rain gear handy, and take shelter if storms are in the area!
