Since many locations across the lower Midwest and mid-South do not typically see measurable snow this early in November, many observing sites are seeing an "Extreme" start to winter, according to AWSSI. This is very much subject to change. AWSSI ➡️https://mrcc.purdue.edu/research/awssi

The Midwest saw our first measurable snow this week & in some spots, it was at least 1-inch. Some major climate sites do not typically report 1-inch of snowfall until early December, so we're a month ahead of schedule. Snowfall Climatology Toolbox ➡️ mrcc.purdue.edu/resources/cl...

October was a warm one, especially west of the Mississippi River where average October temperatures were close to 10°F above normal for the month.
