For the Chicago area peeps, the 21z RAP not only brings in a little system snow but it has deeper inversion heights with more of the lift into the DGZ for the lake effect event. IF it is on the right track with the lake effect parameters, then this would be something capable of producing several inches in the area (3-6?)

Looks like grainers. Beats tank cars filled with who knows what.

Right now the ensembles would say the chances are a little over 50% it will at least get moderately cold later in the month. Hoping to see some good operational runs during the remainder of the weekend.

No Tx still at 65* Our cold won’t arrive until Sunday afternoon. Then we plunge to 24*! Boom!
