After over a month of above average temperatures, a massive arctic front has finally swept through the region, bringing temperatures down below average. Most computer models show Washington getting up to about 40 degrees or so tomorrow afternoon, which would put the high temperature below normal for the first time this month.

After the cloud debris associated with this cold front push east out of the region, a large dome of high pressure should move into the region for 24-36 hours, yielding mostly sunny to partly cloudy conditions Wednesday and into the evening. Once the high moves offshore, a coastal storm is expected to develop about 200 to 300 miles east of the eastern shore which has the potential to spread rain and snow showers into the metro region Thursday night and early Friday morning.

Things get a bit more interesting next week as signs point towards another low developing in the vicinity of the Appalachians next Sunday night and Monday. Temperature profiles are iffy at this point, but there are some indications that this next system could bring a mixed bag of precipitation (rain, snow, and/or ice) to the metro region.
