The cold front that fired off severe weather in parts of the Midwest and Southeast is now ushering in much cooler weather to heat-weary South. The calendar officially reads October, but now it will feel like it.

Break out the fleece jackets, pumpkin-flavored coffee and backyard fire pits; it’s time to enjoy all that autumn has to offer.

Temperature Swing

On Thursday, in the Deep South, temperatures felt more August-like. The mercury rose into the mid-80s in Atlanta and highs reached into the mid-90s in the Dallas area. It was hot. But in the wake of the cold front, weekend highs will only top out upper 70s and lower 80s in Dallas. Expect even cooler weather in Atlanta, by Saturday morning lows will bottom out in the low 40s. North of the city — especially in the Blue Ridge Mountains — temperatures could dip into the mid-30s. Highs on Saturday will only top out mid-60s, but temperatures will rebound into the low 70s by Sunday afternoon.

This shot of cool, Canadian air will also be felt further north — in parts of the Midwest and Great Lakes. Friday night into Saturday morning, the coldest air of the season will settle in across much of the Upper Midwest. Saturday morning lows will plunge into the mid-20s for much of the Dakotas and parts of eastern Montana. Freeze warnings have been issued for a large swath of the Upper Midwest, so if you have outdoor potted plants, you may want to bring them inside. Snow and a rain-snow mix is also possible through the overnight hours for parts of northern Minnesota and northwestern Wisconsin. Accumulations are expected to amount to very little.

Saturday and Sunday expect highs to top out from the mid-50s in South Dakota and the mid-40s in Minnesota, Wisconsin and the U.P. of Michigan. Rain chances will also bring an extra element of coolness to those trying to tailgate at college football games. Pack a jacket and a poncho in these areas.

The cool weather will continue its eastward march through the weekend. Cities like Washington D.C., New York and Boston will see a a nice cool down over the weekend, as highs top out in the upper 60s and lower 70s.

While most of the country is embracing a nice cool down, the western one-third of the country will be seeing an upswing in temperatures — especially California and Arizona. Saturday and Sunday, triple digits will be possible in cities like Yuma and Needles, Calif. Tucson and Las Vegas will all top out in the low to mid-90s. Upper 90s are more likely in California’s Central Valley. Coastal areas of Southern California will warm into the mid and upper 80s. Even normally cool San Francisco will be abnormally warm as temperatures rise into the upper 70s and low 80s over the weekend.

Heat advisories have been issued for much of Southern California and are likely to be in effect through the weekend. If you are outdoors for an extended period of time, be sure to drink plenty of water and take frequent breaks in the shade.

Whatever the weather, enjoy your weekend.
