ILSNOW

12z NAM apparently didnt get the message. Why is this model even around any more. We are within 24 hrs of a potential storm and most models have no precip in the Chicago area and this model has a 13 inches . It should be replaced by a dart board. At 18z is will go from 13 inches to 0.

so Chicago goes from WSW to partly sunny highs in the low 40's!!!!!

Euro caves

0z GEFS

NAM hasn’t gotten the south and east memo (YET)

Would love to see EPS if you can share

Euro goes south and east

yes the mean remains NW of the op run

Chicago NWS snippet Forecast soundings have continued to show that a rain and snow would be the dominant precipitation types with a sharp gradient separating the two p-types across the area. Recent trends have stared to hint at the idea that areas north and west of I-55 would be the most favored for snow and potentially heavy snow as the aforementioned enhanced forcing interacts with it. Given that surface temperatures are forecast to be around freezing the snow would likely be a wet snow with ratios on the order of 8:1 to 9:1. While it is still too soon to narrow down the exact location of where this heavy snow band would set up it is looking like areas under this band could see accumulations in excess of 3 inches which would lead to hazardous travel conditions during the day on Friday, but especially during the afternoon hours.

looks like the NAM from the old days when we would always get 1 huge run before it came back to reality.

18z NAM snow depth and Kuchera

is this good!!!!!

12Z EPS

12z

6z Euro

GEFS follows the op run

18z GEFS (either op run is an outlier or there are amped runs well northwest)

18z GFS

18z NAM Kuchera while the 18z RGEM says what snow for IL. Michigan does well.

12z EPS at 10:1 ratio might be high

GEM is slightly different from NAM and GFS

12z GFS keeps most of the snow out of Wisconsin

12z NAM
