The map above is for the forecasted snowfall amount of our WI FA....
We have the northern/Central parts of Barron/Rusk Counites,and a small area of Northeastern Polk County in the the red area do to a number of reasons..1 higher terrain of said Counties...2 These areas seem to get nail with more snowfall and severe thunderstorms as a rule..So with looking at the last 20 years of data complied by the Weather Center...We see no reason why not to add them areas into the heavy snowfall area...With Iso amounts up to 12 inches..The Other area we have in red will see the highest snowfall amounts,and more widespread.....
Forecast details....
Nam came around to the thinking of the ECMWF model this morning....GFS is still be the problem child like most of this winter,when it comes to storm systems...So will discard very thing it shows as far as the snowfall amounts go...
12Z ECMWF is showing a low pressure sytem over North Central CO The low is forecasted to move towards the Northeast and deepen to around 999 MBS as it pushes into Northeast IA then into far Southern WI/Far Northern IL...Meanwhile a 1036 or so MB high pressure is forecasted to build into ND....The pressure gradients between these two system will increase..Winds could reach the 20 MPH...This will lead to blowing and drifting of the snow...NAM model is still a little South and a tad weaker..Like around 1002 MBS..However not much in the way to change the forecast...Cold Arctic air pours into the area behind this system..With temps warming to around 30 by Tuesday..Models have been pushing this WAA back a day..With some hinting at pushing it back til mid week....
