The Forecast for Western and Northwestern WI...

Main weather headlines will be the Arctic blast that is set to impact the area next week… Also watching Saturday night through Monday for a few inches of snow…Good news is as of right now still no big winter storms for the area over the Thanksgiving holiday… Will get to all this in awhile….

Temps have started their downward trend over the last HR as a cold front is pushing through the FA… Winds Have became rather gusty behind the SFC front 7 to 13 MPH with gusts in the 20 to close to 30 MPH range… Higher gusts found up around the Lake Superior area… Skies have become Partly cloudy most areas….


Problems for the rest of today through tonight… Will be the cloud cover Vis Satellite is showing the Western and Northwestern areas of the FA seeing some holes punching through, this trend should hold through the rest of afternoon… So partly cloudy skies will be ran in the forecast…. Cold front is now moving through my Western FAs… Temps should slowly start to fall as the front pushes through, though the main CAA is well behind said front….. Winds will start to pick up out of the West/Northwest, and be rather gusty for a time through the afternoon into the evening hrs…. Winds could gust to around 20 to 25 MPH …. Tonight the problem will be temps how cold to go… With the computer models in agreement with the next system moving in for the weekend clouds are forecasted to stream right back into the area…. So thinking is to run in the middle teens for low… However if we remain partly cloudy longer temps could easy fall into the lower teens…..

Looking at the ECMWF model…

A 1003 MB low pressure moving along the USA/Canada border shall push a cold front into the area this afternoon this front should clear my FA early this evening…However another system/shortwave will be moving along the border, this should bring in a wintery mix Saturday night.. We see a low pressure system taking place over CO tomorrow… Looks to be an inverted trof reaching Northwards from said low into the area…. 1000 MB low is forecasted to move into Northeastern KS by Sunday night then move Northeast through Central WI… This system will have a little more moisture to work with for Sunday and Monday… Mid level profiles showing this system to have enough warm air in the Mid to SFC level to give us a wintery mix from freezing rain/snow/sleet Sunday and Sunday night before the mix changes over to all snow for Monday…. Looks like a shot of 1 to 3 inches of snow will be possible on Sunday night through Monday early afternoon…. We will have to watch this to see if more moisture can wrap into this system….. Once this low pull Northeast a strong cold front will slam into the area Monday late afternoon… We should see temps falling throughout the day…. Monday night’s temps will be tricky…Right now we will run with the middle teens, however if skies clear off we could be talking about lows in the upper single digits….From Tuesday through Thanksgiving temps go no where but down….. Tuesday temps in the lower 20s cooling off to around the middle teens by Thanksgiving day…. Lows start out toasty in the middle teens…Then cool into the single digits… Still looks like we should see our first below zero readings either Wednesday night or Thanksgiving night…. Models showing a weak system moving in for Wednesday this should bring in some light snows… The way it looks right now this system should remain well to our South and East….Will see what happens as we get closer to this time frame….

Still no big snowstorms forecasted for the area….
