Any type of severe weather activity in the country will undoubtedly receive the lion's share of the weather headlines today (and rightfully so) since there is the SPC has issued a rare January moderate risk of severe weather from the northeastern tip of Texas through southern Illinois and Indiana.
However, I would like to spend a couple paragraphs writing about another effect this storm will bring. In the radar image above, the cold front is well-defined and looks much like a Spring storm that would bring severe weather to the same parts of the country April through August. However, the below image of the current temperatures should tell you how this storm is different.
Do you see the large pool of cool air behind the front? This is the difference between this storm and one that would occur later in the Spring. This cold air is likely to cause heavy snow in the Midwest from southeast Nebraska through Wisconsin and the Upper Peninsula of Michigan. This has prompted Winter Weather Advisories and Winter Storm Warnings to be posted in anticipation of up to 9 inches of new snow.
So, this storm appears to have it all. It is a Winter storm with ample moisture and warmth ahead of the cold front to provide the possibility of severe weather and thunderstorms, while also have the capability of tapping into the cold air behind the front to produce Winter-like conditions in the Midwest.
