The forecast for Western/Northwestern WI, along with the froecasted snowfall map.

Forecast concerns…. Clipper like system pulling out of the area today brought a widespread 1 to almost 3 inches of snow through a good part of the FA…. Another system one track for tomorrow into tomorrow evening which should bring another 1 to 3 inches for most of the area… See forecasted snowfall map for where that may occur…..Temps are going to be tricky today through the weekend, before colder air flows into the area for the end of the weekend into next week and into the longer term….


As of 10 AM skies are cloudy… Temps in the lower to middle 20s… Winds are light out of the North/Northwest….. Fog is being reported at many of the stations…..


This morning’s charts shows a 1007 MB low pressure system centered over the Northern part of Lake Superior… With a cold front reaching Westwards along the MN/Canada border..Front then extends Northwest into Canada to a low pressure system in Northeastern British Columbia Canada…. Western CONSUS weather is being controlled be a rather large ridge of high pressure at the SFC and throughout the upper levels… Meanwhile the 982 MB low pressure is centered off the Coast of ME… A weak area of low pressure system is found over Eastern AR/Western TN, with a cold front reaching Southwest through Southern AR back into TX…..

Cold front to our North is forecasted to move into the area later tonight… Meanwhile the low over British Columbia is forecasted to move into Northern Alberta…Low is forecasted to track Southeast from there into Northwestern MN then down through Western WI then over to Southern MI/Northern IN… Will keep flurries/mist going today through tonight with areas of fog possible also.. Then bring in snow for Friday will hold onto snow for Friday night.. Then flurries for Saturday as a trough swings South/Southwest into the area…Meanwhile on Saturday a rather large 1040 MB high pressure system will build South into the area for Sunday…Sunday night/Monday’s time frame models have really back down a winter storm that was forecasted to have little effects on the areas as far as snow goes, now we see more of a trough over Western MN that will work it’s way Eastwards… However a 1008 MB low pressure is forecasted to form in the TX panhandle … This is forecasted to lift Northeast towards East Central IL and Western IN.. Meantime 1044 High pressure is forecasted to drop into MT then builds into the FA for Tuesday/Wednesday…


Next shot of light snow brushes the are on the 3rd as an area of low pressure remains well North of the of the FA… Thinking right now is my Northeastern areas will have a better chance at light snow then the rest of the FA… Once again we see the upper level ridge take control of the Western CONUS after a brief cool down in them areas…. Out East upper level trough still holds strong.. Will bring in another shot of light snow for the 4th as a short-wave /WAA starts to kick in will hold onto the 6th as a cold front is forecasted to move Southeast into the area… Another short-wave/clipper like system moves in for the 8th .. So to recap the…. No big snow storms as far as the eye can see, just off and on light snow through this time frame… Would think by going past trends that each system could bring 1 to 3 inches of snow….Remains to be seen however the way most of this Jan has been going really see reason to argue with that…..Looking at the temps…. We start the cycle on the cold side…. We do see a nice warm up coming in for the 5th temps could be getting closer to 30 by then…. That will be short lived as more cold air moves South into the area on the 7th on the 8th /9th Models are not in really good agreement on the Arctic air… GFS slams us hard with it the other models are not as cold… GFS keeps the Arctic air in place right through the end of the forecast cycle…If GFS is right this could be the coldest air of the winter…. I’m not buying into the ATTM.. 1 to far out in time.. 2. GFS track record this has not been that good….
