Off to my adoptive home state, Indiana, where I spent more time outside of Minnesota than any other. And yes, this is a rare “all I day” in which all the sites we discuss today (Ithaca, Indianapolis, heck even International Falls in the previous post) begin with the letter I! Thank you Sesame Street for bringing this to my attention.
At 1254PM, ET, Indianapolis was reporting a temperature of 19 degrees with mostly cloudy skies. A weak trough over the Lower Mississippi Valley was generating a band of snow that spanned through southern Illinois and would eventually nose it’s way into Indiana. A strong, digging jet still ran through the southeast, and would allow the band of snow to increase in coverage and intensity along the boundary, southwest of Indianapolis while the associated surface troughs comes into phase with an upper level wave crossing the international border.
The surface trough will lose some of it’s muster overnight tonight as it tries to phase with the deep digging trough over the western Gulf of Mexico, but some leftover flurries have a chance to find their way into Indiana tomorrow morning while more substantial development takes place over the Gulf. A remnant clipper driven by this upper wave will move well north of Indiana, but will clear snow out of the state’s capital through Monday, while the stronger developing low over the northern Gulf will organize and draw moisture to itself and away from Indiana. Expect a dry, if cloudy day for Tuesday.

I was really surprised to see snow in the Tuesday forecast for so many, but then I remembered the whole thing about it always snowing when there are clouds in the Great Lakes in the winter. Anyways, here is the satellite, showing a broad swath indicative of another developing low. This is going to be a bruiser along the east coast.
