NEW SNOWFALL NUMBERS....
The 18z runs of the U.S. based models have cleared. There was a decided shift north on all 3 versions. The only outlier to these solutions is the EURO which is further southeast. It's full version won't be down until midnight tonight. With that, the latest and greatest.
The 3k NAM
I'll be surprised if the EURO does not make some sort of move to the north tonight. Then again, stranger things have happened, especially with this storm.
Winter storm warnings and advisories will be issued at some point tonight. Along with the snow will come strong winds that are likely to gust more than 30 mph. Snow begins Sunday morning and travel in much of my area will turn difficult by Sunday afternoon.
Here's some additional information from the NWS in the Quad Cities and Des Moines.
Remember, we are still 36 hours out so changes are still possible although they should be minor if all goes according to plan. Roll weather...TS
