Oct 1, 2021 – The next 90 days will transition from fall to winter. In areas of the Northern Plains and Rockies, winter will come early with snows starting late in October across the Rockies and Plains. A couple of snowstorms will come out of the Rockies and into the Plains and western Great Lakes during this period. Some of the storms can be heavy.
Another area of snow will be across the Northeast and Appalachians. That area could see snows starting in November and becoming more frequent in December. At least one heavy snowstorm will hit with over 6 inches of snow. Many of these areas will see above normal snowfall this winter.
The Southeast will see stormy weather which will be combination of late season tropical systems and pre-winter storms that will get started in November. Some severe storms and flooding may occur during this period.
While temperatures will gradually get colder, the core of the coldest weather will be limited to the Northern Plains and Northern Rockies. The warm weather will remain across Texas into the Desert Southwest.
