Not that this is set in stone, but might be another example of the medium range guidance not seeing the subtleties of NW impulses. Patience is warranted and sometimes you get surprises...

Brewers Posted January 20, 2014 Share Posted January 20, 2014 Radar returns are looking good over SE WI right now. Little vort max moving along the front along with a deepening DGZ, maybe we can have an over performer. edit: seeing locations reporting -sn but better than 5 mile viability isnt a good sign though.

This could be relatively fun. Looping the p-ytpe maps, LES band certainly making inroads into Chicago, if not further north into Geos-land for a time.

I'd say better than 50/50 odds that some part of Chicago picks up 6", whether it's downtown or some of the neighborhoods on the south side. Band looks a bit transient but if it slows down then things may get really fun there. LOT must love to forecast these situations...a city of 3 million at the mercy of a 10-15 mile wide band of heavy snow. Link to comment Share on other sites More sharing options...
cyclone77 Posted January 20, 2014 Share Posted January 20, 2014 Looks like a narrow swath of 2-3" with localized 4" amounts should pass a little south of here tonight. We should still get a fresh coating here. Going with 1-2". Link to comment Share on other sites More sharing options...

Hoosier Posted January 20, 2014 Share Posted January 20, 2014 Regarding the lake effect, omega is basically perfectly located within the DGZ...should rip dendrites with typical high LES ratios. Decent moisture above the inversion tonight into tomorrow and strength of low level flow would favor pretty deep inland penetration. Link to comment Share on other sites More sharing options...
