The early outlook calls for smooth sailing if you plan on travelling next Wednesday for Thanksgiving. The only real travel trouble you might experience is in the southeast. A storm lifting north from the Gulf will bring rain to much of the Mid-Atlantic region. It does appear the Arctic air that comes crashing in here Friday will linger through the holiday though. We could be anywhere from 10-15° below average next Thursday. The graphic below displays the weather for noon on next Wednesday. That is rain in the southeast and a little snow in Montana and over Lake Superior.
My best guess for next Wednesday and Thanksgiving:
Wednesday: Partly cloudy, 35°
Thanksgiving: Partly to mostly cloudy, flurries possible, 32°
Could be worse…
