Significant Snows (Mon/Tue)

Well previous posts indicated that significant snowfall would be possible by the beginning of the week and those thoughts are likely to happen. Only problem now is exactly where these significant snows are going to occur! Lately, models from the GFS have trended slightly north and the NAM/WRF is pushing the heaviest snows significantly further north than current forecasts have it. Currently, Winter Storm Watches have been issued for extreme eastern Nebraska, southern Iowa, central Illinois and then even further east through the Ohio Valley and into the northeast.

Even though the NWS has issued those watches in that area, models are well north of that lineup as far as Iowa/Minnesota and South Dakota go. The snowfall forecasts then get back on track as the system enters IL and the Ohio Valley. But, no matter where the snow falls it is likely to be fairly significant with the NWS as well as models agreeing that at least 5-8 inches is likely in the heaviest band. Local amounts nearly 10 inches I think should be included as well if some type of banding can occur... Look for this heaviest snow to enter Iowa by Monday Night and quickly pile up overnight and then taper of by Tuesday. Next update likely late tonight or sometime tomorrow...
