Not much rain from this front
The latest cold front pushed through here before dawn, with the official passage at Shannon Airport recorded between 4:35 and 4:55 a.m. this morning (Wednesday). The winds swapped around from southwest to northwest, the air pressure bottomed out and began rising, and both the air temperature and dewpoint started dropping…all signs of a cold frontal boundary passage. The precipitation that has been falling behind the boundary marks this as an “anafront“.
Later today the clouds will clear off and the sun will warm things up to about the 60 degree (F) mark, but gusty northwesterly winds will sweep in colder and much dryer air this afternoon and tonight that will result in a low temperature near the freezing mark (32) Thursday morning and a high tomorrow in the upper 40′s.
The light amount of rainfall from this system hasn’t helped the dryness here in Virginia much. This graphic from the Climate Prediction Center shows the drought situation in the Commonwealth worsening:
As you can see in the associated table over half of our state is either abnormally dry or in a moderate drought. Hopefully a stronger surface low pressure system that the models are indicating will travel up the Ohio Valley early next week will tap into moisture from the Gulf of Mexico and bring a more substantial rainfall (sorry, it looks like it’ll be too warm for snow) to the area.
Until then the rest of this work week looks dry with temperatures moderating into the weekend as we climb back into the 60′s for highs.
