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

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

(MAP: Current Temperatures)

Jet Stream Pattern Next Week

Such is the case next week 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. Lows in the single digits and teens are likely in North Dakota, northern Minnesota and northeast Montana.

Tuesday (MAPS: Highs | Lows): Highs may hold in the 20s in much of the Upper Midwest. Most cities across the Midwest and Northeast will not rise out of the 30s or 40s. Some single-digit lows are likely in parts of North Dakota and northern Minnesota. Morning lows in the teens may plunge as far south as northern Kansas.

Wednesday (MAPS: Highs | Lows): As illustrated by the map to the right, temperatures will be up to 20 degrees below average across a big area from the Midwest to the Deep South and East Coast. Highs may hold in the 50s in parts of north Florida. Lows in the 20s may plunge as far south as the Texas Panhandle, Tennessee Valley and Carolinas. Some daily record lows may be threatened in parts of the Northeast (low-mid 20s). Thirties for morning lows will shiver much of the Deep South. http://www.weather.com/news/weather-winter/cold-snow-midwest-east-next-week-20131107
