High pressure over Virginia this morning will move over the open waters of the Atlantic Ocean today before weakening. Strong westerly to northwesterly flow on the northern side of the high pressure area will once again reinvigorate some gusty winds over the Capital Region this afternoon. Despite generally mostly sunny conditions, it will be quite chilly, with the wind making it feel all the more colder.
A series of Arctic cold fronts, or as they are termed ‘clipper’ low pressure systems, will descend upon the region from central Canada starting on Wednesday and lasting through Thursday. The first system will approach the region late tonight, and sweep through Wednesday morning. The second system will approach the region Thursday morning, passing through the area during the daytime hours. Each system will bring a chance of light snow and/or snow showers to the region. Although accumulations are not expected to be hefty with these systems, they may desposit a quick inch or two of precipitation.
Of greater importance with each successive system’s passage, will be the introduction, and subsequent reinforcement of very cold air. Temperatures may range from 10, to as much as 20 degrees below normal through the end of the work week.
