South Wisconsin May Get Crushed with Late Season Snow

Sorry everyone, the automatic publisher didn't work! Sorry!

The latest GFS is showing over a foot of snow for southern Wisconsin and far eastern Iowa. This comes as a fast moving storm system appears to absorb additional moisture to provoke additional snow amounts.

Before I go any further: This image may be produced with 10:1 ratios, which would be higher than what is being shown here. The keyword is 'MAY', because a comparison to other 10:1 ratio images yielded different results. That said, I am treating this image as a 10:1 ratio image in order to not get everyone's hopes up too high.

Anyhow, I would expect a realistic scenario to be 1-4 inches in southern Wisconsin, with another 2-4 in Pennsylvania. I really don't know with the difference in images using the exact same data, which should yield the same results.

Southwestern Low May Ignite Severe Weather in Plains

The ECMWF is projecting that a large low pressure system will swing into the Southwest and likely ignite some showers and storms if it should progress eastward into the Plains.
There isn't too much I can say about this storm system, but the jet stream appears to be latched onto the system, which would increase tornadic shearing and the overall intensity of the system.
