PM Update: Time to Think Wind Chill Factor?

By Ian Livingston

Lots of sun Wednesday with below-average temperatures

A dry cold front that passed through the area during the midday has left some gusty (as high as 30 to 35 mph) west and northwest winds in its wake. Temperatures that reached the low and mid 60s before the front arrived will drop back during the late afternoon as cooler air rushes in. Watch out for blowing leaves and other small debris on your way home, and be ready to bundle up once the sun goes down.

Tonight: Another in a string of cold nights is on its way. Most places will run about five degrees below average, which means low-to-mid 30s for the coolest suburbs to around 40 in D.C. We will see mostly clear skies, but continued gusty breezes from the northwest will help keep temperatures from hitting rock bottom -- a slight wind chill will be noticeable from time to time.

Tomorrow: There will be plenty of sun on Wednesday, but not much in the way of warmth. Look for high temperatures to only rise into the mid and upper 50s for most places, while D.C. or areas to the southeast could touch 60. A pesky northwest wind will slowly weaken.

By midnight tonight, there's going to be a high-pressure base to our northwest and a low pressure system to our northeast--both of which will slam cold northern air into our region. Take a look for yourself:

Any word on what the weather will be like for Obama's speech in Leesburg, VA tomorrow at 5ish? Probably some coats might be in order... Thanks!
