Forecast for Western/Northwestern WI.

Not a lot to talk about through the short term and midterm… The blocking pattern holds it own like it has for sometime…Though there are signs it may be breaking down ….. Temps to warm into the middle 20s for all of next week… With chances of on and off light snows….


Skies this late morning are cloudy with some breaks up along Lake Superior…. Some stations are reporting light snow/flurries… Temps are in the middle teens to some upper teens….Winds are from the West from 5 to MPH…..


Strong area of low pressure on the Western side of Hudson Bay Canada is forecasted to move towards the West, as it does it will gain strength… This keep sending down weak impulses into the area on the Northwesterly flow… This will insure the FA mostly cloudy skies, along with some light snow/flurries from time to time.. As far as LES go they should begin to dissipate later today…. All light snow/flurries should be ¼ to 1.00 inches at tops… As far as the snow storm potential for early next week, this looks to setup over in MN once again.. Timing and placement on this system is still somewhat still up in the air…Using past trends on last two systems.. Thinking is to trend the same way for now… Models have been trending slower with said system and a little more to the North… We will have to watch this if that trend does hold then we could be dealing with more in the way of snowfall… It all boils down to if the blocking pattern can weaken enough to allow this system to move closer to the FA… Thinking is same parts of MN will be under the gun as last Monday….

After that system move out not much cold air behind it as the low in Canada seems to be drawn warmer air in them part, hence will not allow for any Arctic blast anytime to soon… Next system to effect the FA comes in for Christmas Eve and Christmas day time frame…. Once again the way the weather pattern has been this storm as its eyes set on parts of MN, leaving my FA basically high and dry…Just some light snow….Once again we will have to watch this as things could change…

So will run with mostly cloudy skies right through the end of the upcoming work week, with a chance of off and light snow/flurries….Highs in the middle to upper teens to start warming to the lower to middle 20s… Lows in the starting off either side of zero warming to the lower to middle teens… If we do get more clearing we will have to watch the lows as they could be colder…


We find ourselves under a 1035 MB high pressure system… Meantime a power storm system over the Eastern Coast line and one over the Western Coast line…. Will ensure us of a Northwesterly flow once again..This does break down by Friday Dec 31st. We do get into a Westerly flow then to a Southwesterly flow by end of the cycle…. This will allow for a few things to happen…..1st off allow for a better chance at seeing some better snows through this forecast cycle along with temps staying right around normal to above normal.. We shall see what plays out… As of right now this long term forecast is based on that the upper level pattern will be changing…We will not try to time storm systems at this point in time... Just doesn't make sense this far out, until the blocking pattern does for sure change,once that happens then we will give it a shot....
