Timing late tonight through Saturday evening.
Forecast models in rather good agreement, just some timing issues I do like the ECWMF, Nam, and SREF for this storm system…
Low pressure will be moving along the MN/IA border tonight and then Across far Southern WI as it does the low is forecasted to deepen…I have decided to expand the heavier snowfall amounts all the to include Polk, ST. Croix Counties in the 12 to 15 inch range… I has also decided to go higher with 15 plus inches for most of Barron County, small part of Northeastern Dunn County, Northern part of Chippewa County, South/Southeast part of Washburn County, all of Rusk County and a good part of Sawyer County…South/Southern parts of Ashland and Iron Counties…. Rest of the forecast area should see 8 to 12 inches of snow… Map below….. Reason for upping the snow amounts is as the low deepens just to our South it should pull more moisture into the area…In my Southern zones could be a time that there is some freezing rain/sleet mix in from time to time…
Now as the low deepens and strong high pressure to our West/Northwest pressure gradients will increase… This will lead to winds up to 30 MPH at times.. This will cause widespread near to blizzard conditions throughout the FA, mainly in open Country areas…. Near to whiteout conditions will make for travel to become impossible… Now is the time to get ready for what looks to be the biggest snow storm so far this winter…. I would not be shocked in the NWS runs with a blizzard warning later today/night…. If one has to travel later tonight/tomorrow make sure you have a winter weather safety kit in your vehicle…Let someone know your travel plans with time of leaving and time of arrival….If you become stuck stay with your vehicle and call for help… Best thing to do is get your running around done today/early tonight, and hunker down later tonight/tomorrow…To tops things off Arctic air will be flowing into the area as well this will lead to very dangerous wind chills… -15 to -25….. As temps slowly fall throughout the day…
This is a dangerous winter storm…
