A strong cold front is moving through the central US today and should get to the Southeast by Monday night. Rain, cloudy skies and some gusty winds will accompany the cold front through the day on Tuesday, but it will be into the eastern Carolinas by late Tuesday night. The rest of the week looks cool and dry. The mountains could see a little wrap-around rain on Wednesday from a low pressure center that is expected to develop along the front on the East Coast, but that is the only other rain in the forecast. The tropics do not look like they will be a concern this week.
Temperatures behind the front will be a lot cooler, at least for a few days. I don’t see a chance of widespread frost with this front, but the morning of October 3 could see some scattered frost in pockets in the Southern Appalachians. After this, temperatures should moderate for at least the next week.
