Geos Posted November 20, 2015 Share Posted November 20, 2015 Euro in agreement on location of lake effect band over NE Illinois. ecmwf_tsnow_chicago_7.png It's amazing on the model agreement of the LES and the tight location between Racine and Lake Bluff.

Thundersnow12 Posted November 20, 2015 Share Posted November 20, 2015 Here is the zoomed in 4km NAM snowfall amounts. Thought it really picked up on lake enhancement well along with lesser amounts just along the immediate lakeshore but still solid amounts just to the west across Cook co.

Hoosier Posted November 20, 2015 Author Share Posted November 20, 2015 Here's the 2m temp map from the 17z HRRR to go along with the image that Thundersnow posted. Seems like the model is showing rain where it has temps AOA 35. Link to comment Share on other sites More sharing options...

Has the band further S than the GEM or GFS. GFS seems sloppy with the band. Link to comment Share on other sites More sharing options...
Hoosier Posted November 20, 2015 Author Share Posted November 20, 2015 Oops correct, looked at it fast. Still think it's overdone. If it's just assuming rain where temps are 35, then yeah, it could be wrong as we've all seen it snow at those temps. But I'm not sure how it calcuates ptype.

But I'm not sure how it calcuates ptype. I wish we could see the upper layers temperature-wise. At 850mb, the HRRR is about 2 degrees warmer than the GFS or the NAM. It could be that the model is simply on the warmer side of guidance. Link to comment Share on other sites More sharing options...
