Temperatures only dipped into the 40’s across the Capital Region overnight last night thanks to increased cloud cover and southerly to southwesterly winds. A warm front was well north of the region this morning, and had passed through the area yesterday, warming the temperatures. Meanwhile, a cold front was draped from just south of James Bay in Canada, through the Michigan, Indiana, and Ohio border area, south and west into northern Texas. This frontal system will approach, and eventually pass through, the region later today and overnight tonight. This frontal passage will bring the threat for some showers, some of which may be accompanied by a rumble or two of thunder.
Strong Canadian high pressure attempts to build into the region, after the frontal passage, by Wednesday. However, a wave of low pressure looks to form along the frontal boundary, over the central plains by Wednesday evening, causing the front to stall just to our south by Wednesday night. This should not hamper the region’s weather on Wednesday though, as sunshine mixes with clouds, and temperatures reach near to slightly above normal levels.
The ‘indecisive’ frontal boundary meanders south of the region, before taking on warm frontal characteristics by Thursday morning, and lifting back northward toward the area. After another potential round of showers on Thursday afternoon and evening associated with the warm front’s advance, a nose of much milder air looks to poke into the region for Friday. Some of the warmest air of the season thus far looks to visit the region to close out the work week. This will be short lived though, as a potent cold front, associated with a sharp drop in temperature, looks to pass through the region during the overnight hours on Friday.
After the possibility of some residual early morning showers on Saturday, skies should begin to clear, and a brisk northwesterly wind should blow across the region by afternoon. Temperatures will be noticeably cooler, some 10 to 20 degrees cooler than those forecast for Friday. High pressure settles in for Saturday night, Sunday, and Monday, with temperatures still hovering near to slightly below normal.
