Discussion
Precipitation is advancing northeastward this morning from the Southeast US and should arrive here during the mid-morning hours. This moisture will encounter some cold, dry air in the Northeast US that is currently being anchored by strong high pressure. As a result, there can be some evaporative cooling at the onset of the precipitation in the lower part of the atmosphere and this could cause some sleet to mix in with the rain; especially, to the N and W of the District. Low pressure headed for the Ohio Valley early today will transfer its energy to a newly forming coastal low near the NC/VA border and this will become the primary system later today. The precipitation will end later tonight from southwest-to-northeast across the metro region. After a bit of a milder day on Wednesday, the coldest air of the season so far will arrive later Thursday. On Friday, temperatures will do no better than the 30’s for highs, the wind will generate even lower wind chill values, and there can be a few snow showers. The below-normal cold will continue through the upcoming weekend and it looks like there will be additional Arctic blasts into the eastern US over the next few weeks.
