Some new models are in and at least for now no major changes have taken place with the storm showing no tendency to go any further southeast. That means the heaviest snows 2-3 inches should be near and southeast of the Quad Cities. The southeast third of Iowa should see 1-2" inches with the heaviest over the southeast tip where there could be some 3" totals. Amounts get lighter as you NW towards Waterloo where the 1" amounts are expected. Here's the raw snowfall forecasts from 3 models.
The 3k NAM
The snow begins early to mid afternoon in my southern counties and works its way north to HWY 20 around 4-5pm.
Keep in mind a potent arctic blast arrives Wednesday night with high winds and falling temperatures that in many areas from the Quad Cities NW will produce readings well below zero by Thursday morning. Bitter wind chills and blowing snow are also on the table along with lingering snow showers!. Not gonna be very nice! Roll weather...TS
