Just when you thought it would get warm again, we're going back to winter? What gives?

The D.C. area is running about 15 to 20 degrees warmer than it was at this time yesterday. This is in association with a cold front that lies over the Ohio and Tennessee Valleys that is approaching our area from the west. It's a strong front and very high winds are helping push in the milder air ahead of it. Just a few thousand feet off the ground winds are screaming out of the southwest around 50 to 65 m.p.h. The strength of the front has been aiding to some severe weather across the country with numerous wind reports and even a report of a tornado today. Here's my video analysis for the day showing the front, some interesting temperature maps and the all important 7-day forecast.

What I'm keeping my eye on: Thursday's upper-level disturbance looks to track right through the D.C. area in the evening hours. This may be enough to give the region a little snow though I'm not too impressed with the prospect of it putting down measurable snowfall. Saturday will also be interesting, as enough cold air may get locked in at the surface for a period of freezing rain. Remember though, this looked like snow yesterday and freezing rain today. Will it look more like regular old rain tomorrow? Below is the current snow water equivalent map showing the lack of snow over the Mid Atlantic. Weak!

Why you won't like Wednesday: This one is pretty simple. Winds out of the northwest around 10 to 20 m.p.h. along with temperatures around 40 degrees will make it feel like it's in the 20s for the majority of the day.
