Possible significant snow Monday and Tuesday

Thanks to Beau G. for pointing this out. WRF and GFS have been showing a large winter storm slamming Iowa, southeast Minnesota, southern half of Wisconsin, northern Illinois, and Michigan with a half foot or more of snow possible. Latest runs by the WRF are pushing this area of precip farther north in to the southern half of Minnesota, most of Wisconsin, northern Iowa, and Michigan. Looks like from the Twin Cities north could pick up to 5" inches (although the NWS is only calling for 1") and areas south of the Twin Cities could see over 6" if the models pan out. The one thing i am kind of skeptical about is that the area of precip the WRF shows just explodes between 12z and 18z which i dont think is really going to happen, i think it is more of a glitch in this run. waiting for the GFS to update and will post more later...
