From Rusty Garrett:
The first of two cool fronts to arrive this week may bring a few isolated sprinkles across eastern most areas this Tuesday evening. Most locations will likely not see any rain and rain odds are only near 20%. Cooler air will continue to move in as north winds increase to near 25 mph. By morning, lows fall into the lower 40s with wind chills in the upper 30s. Winds will remain breezy Wednesday with mostly sunny skies and highs only climbing into the upper 50s and lower 60s.
Winds will go relatively calm Wednesday night, allowing temperatures by Thanksgiving morning to drop into the lower and middle 30s with a chance of patchy frost. The weather remains gorgeous for Thanksgiving Thursday with afternoon highs rebounding to near average in the middle and upper 60s.
If you're out early and shopping on Black Friday, you might want to bring a light jacket, as overnight temperatures fall into the middle 40s. South winds return during the day, allowing us to warm into the middle 70s. Temperatures remain in the middle 70s Saturday as well, but an afternoon front will bring slightly cooler air into Central Texas.
