Once the cold gets in, it will stick around through much of next week across the eastern part of the country with the greatest deviation from normal across the Great Lakes. We have one shot of snow per the snow map below Sunday night into Monday followed by lake-effect snow as the cold comes across the lakes next week. We even have a shot at waterspouts from late Tuesday through Friday as the coldest air comes in aloft.
Some of the longer-range models are hinting at shots of cold air through early December with deviations below 3 degrees. The CFS seems to be bullish on the cold weather sticking around and even says that a snowstorm in the Mississippi Valley and Ohio is possible around or after Thanksgiving. It keeps the Southeast warm through the period which is why we end up with a storm cutting from Texas to the Northeast per the CFS.
I am throwing these ideas out there today because while we were in a period when the weather seems to be a month behind, it now appears the pattern is quickly catching up to the season and may even go a month ahead.
A stormy time across the southern Plains today into Saturday. Flooding rains will be the main issue during the period.
Storms will be severe in the southern mid-Atlantic and in the Southern Plains. Tornadoes possible in the Plains Friday.
The focus of the severe weather will be across southern Iowa into western Illnois where storms should develop around the upper-level low.
Storm coming out of the Rockies will bring tornadoes and severe winds to the Plains and Mississippi. Mid-Atlantic has big storms too.
Severe weather will occur this week as a series of storms move across the country.
The pattern will become active in the Plains and Midwest starting Sunday and lasting into next week.
