And it's certainly blowing me no good today.
The 18Z TAF's are out and the forecasts for my destination area are poor:

If I were to depart KBDR about 22Z I'd arrive in the area of KVKX about 00Z, when the KDCA weather is expected to be 2 miles in drizzle with a 900 foot overcast. Andrews AFB is forecasting something similar. The RNAV RWY 6 approach into KVKX has a 680 foot minimum descent altitude (MDA) and a 1 mile visibility minimum. That's too close for confidence, and if I have to divert to Manassas (KHEF), the forecast for nearby Dulles (KIAD) goes down to 1/2 mile visibility at about that time. That makes my alternate a problem.
So, I've opted for the train. I have a good book to read and I should be home by about 10:30. The annoying part, of course, is that I then have to take the train back on Monday morning and the weather will probably be fine.
