  1. N IL will have this moisture linger until at least noon until 1.  We would have needed clearing by then. It’s imperative in these setups - we’ve seen this over and over.  The northerly flow is a big determining factor.  That and an over worked atmosphere. 
     

    not saying that there won’t be storms, but perhaps not moderate risk worthy IMO and if so, further south

    Woke up to weather channel showing 8-12” for Chicago and I’m like :bike:

    came here and starting looking around and I’m like :sled: game still on. 

     

    No final call yet, but feeling confident 8”+ around here in Oak Brook. Coffee should be ready now

    Where in oak brook are you?  I’m at York and 22nd

    If the ECMWF and NCEP idea comes to pass, the snow on Thursday stands to be well above average ratios as the cold air mass deepens over the region. Forecast soundings are showing the DGZ increasing to 200 to 300 mb deep, or as deep as 7kft+. GFS in particular has the DGZ almost down to the ground and up to 700 mb. Progged lift is modest during this time but the high ratios would compensate.

    I'm also becoming more interested in the lake enhancement to lake effect component for northwest Indiana. Very good air mass with 850 mb temps down around -18 to -19C over the lake Thursday night and some of the models slowly pivoting the lake induced convergence axis. Inversion heights near 8kft, 850 mb to lake delta T around 20C and at or above 400 j/kg of lake induced CAPE could support heavy rates with > 20:1 ratios in the band.

    Aren’t bands in that type of setup pretty narrow?
