After an already cold start to the month from the northern Plains to the Northeast, an even colder air mass is set to blast into the East. The first shot of deepening cold will be ushered in by a storm bringing soaking rain to portions of the South and disruptive snow to portions of the Northeast.
The core of cold will gradually shift from the northern Plains into the Great Lakes and Northeast from Wednesday through Saturday, making it feel more like the middle of winter rather than early November in some places.
High temperatures will struggle into the 20s and 30s F across the northern Plains and Upper Midwest Wednesday into Thursday.
Coupled with a stiff breeze, AccuWeather RealFeel® Temperatures will spend most of the day in the teens or even single digits for some areas across eastern Montana, the Dakotas and western Minnesota.
While Wednesday will be a mild day across the southern and central Plains and mid-Mississippi Valley, Thursday will mark a turn to much colder weather in these regions. Daytime highs in these areas will be some 20 to 30 degrees colder Thursday when compared to Wednesday, as temperatures struggle into the 40s.
The core of the cold will shift farther east still during Friday into Friday night, focusing on the Great Lakes, Ohio Valley and Northeast. Most locations in these regions will bottom out in the teens and 20s by Saturday morning.
By Friday the chill will also penetrate into the Deep South. Afternoon high temperatures Friday will be 10-20 degrees below normal for early November across the Southeast, with widespread temperatures stuck in the 40s and 50s. Even temperatures in communities along the Gulf coast will struggle into the 60s.
This will set up the potential for widespread frosts and freezes across the South Friday night. Readings for many communities away from the Gulf Coast will fall through the 30s Friday night, with some upper 20s even likely from Arkansas to northern Mississippi and northern Alabama into the Tennessee Valley.
"Residents throughout much of the South will need to be prepared to protect sensitive vegetation at the end of the week," Brett Anderson AccuWeather senior meteorologist, warned.
Some might also need to allow for some extra time to scrape frost off of the car windows before heading out in the morning.
The Florida Peninsula will be the last to feel this initial cooldown, with temperatures not expected to tumble until Saturday in places like Orlando and Tampa. Even then, temperatures will only return to near or a few degrees below normal across Florida. It will be more relief from the persistent heat the state has been experiencing thus far this fall, rather than a turn to chill.
Following a brief moderating trend across the Plains and through the East later this weekend, the stage will reset for an even colder blast at the start of next week. A direct shot from the Arctic will be directed at the eastern United States, potentially being ushered in by another, larger storm system tracking along the East Coast.
During the first couple of days of next week, most of the eastern two-thirds of nation could be 10-20 degrees below normal for mid-November.
"A widespread killing freeze is likely to end the growing season across much of the South early next week," said AccuWeather Senior Meteorologist Dan Kottlowski.
Subfreezing low temperatures could stretch all the way to the central Gulf Coast. People in a huge swath all the way from the Dakotas to northern Texas, eastward to the Carolina coast and through the Northeast will likely wake up Tuesday morning to temperatures in the teens and 20s.
The most intense cold, with low temperatures in the single digits and even some subzero readings, coupled with gusty winds, will focus on the northern Plains Monday morning, before shifting to the Great Lakes and interior Northeast Tuesday morning.
"While the extreme cold is expected to give way to a milder pattern to close out November, it may take until the third week of November to clear out the well below-normal temperatures from the northern Plains through the Great Lakes," AccuWeather Lead Long-Range Meteorologist Paul Pastelok said.
