Storm Update

There have been no drastic changes but the 0z runs did nudge the main band a bit further south with less QPF but dont know if Im buying into that yet. waiting for the hi-res models to come in now. going to be intesting if the trend continues. the hi-res NMM holds its ground.

think chicagoland area from 1-88 on north will see around 6-10" with locally higher amounts taper down to 2-4" across the far southern counties due to having mixing problems. some pretty impressive returns going on right now down south in TX and OK with some thunderstorms. whats pretty cool is the WAA precip all the way in western IL with the ULL still back in the southwest.

here is an image from the SPC 4km WRF showing a very intense snow band from southeast IA to chicago



and this from the hi-res NMM



if things hold true then a snow day for parts of the area could be a real possibility given the heaviest snow will be falling during the overnight hours into the morning.

and lastly here is the text from the winter storm watch from the chicago office...
