Cold Blast for Midwest, South, East Ahead; A Little Snow For Some 

 

Typical of fall, temperatures do their fair share of rising and falling with each cold front that sweeps through.

Jet Stream Pattern Next Week

Such is the case over the next several days as the jet stream takes a sharp plunge south from Canada across the Plains, Midwest, Deep South, then into the eastern states. This jet stream dip will be accompanied by a chilly, expansive area of high pressure at the surface that can be traced back to the Arctic.
This pattern change will lead to a widespread area of well-below-average temperatures. Let's take a closer look at the colder forecast details and see if any snow will also be squeezed out.

It Will Turn Colder Next Week

Highs Compared to Average Wednesday

Temperatures over 20 degrees below average will progress south and east from the Midwest to the Gulf Coast and East Coast beginning Monday.
Monday (MAPS: Highs | Lows): Temperatures may not rise out of the upper teens or 20s in the Dakotas, parts of northeast Montana, Minnesota, northern Wisconsin and Upper Michigan on Monday afternoon. Morning lows in the single digits and teens are likely in North Dakota, northern Minnesota and northeast Montana.
