Forecast for Western/Northwestern WI..Along with forecasted snowfall amount.

Well if you love snow, you will love this forecast…If you hate the cold, you will not like this forecast…. More snow on its way for this afternoon/tonight… More snow for Sunday night and Monday… More snow for Wednesday and Thursday… Get the picture…. However these snowfalls won’t really be much to write home about… Looks like 1 to 4 inches with each passing system…..

Skies range from cloudy to partly cloudy throughout the FA..Satellite confirms this as seen in the vis imagery. Temps in the lower teens to middle teens…. Winds a rather light to calm… Some stations are reporting fog…

Yesterday’s weak system is now over Northeastern WI…. We see a few areas of weak low pressure areas of around 1024 MBS or short-waves in far Northern MN and over the Western part of Lake Superior…. Meanwhile our next system of interests is over Northwestern SD… This system is forecasted to dive Southeast .. The best dynamics shall be found with the Northern low pressure… Still appears to be enough forcing with the Southern system to produce snow throughout the FA….. See map for forecasted snowfall amounts for later today and tonight….As both theses systems move through one to the North the other to our South…We shall see an Arctic cold front slam into the FA… Winds will switch to the North/Northwest…. Should be around the 10 to 15 MPH range for Saturday… This may cause some blowing and drifting issues…. We will watch for this throughout the day and into the night….We get a break in the action for most of the weekend…. Temps will be somewhat chilly…. The warmer day does appear to be Saturday with highs from 10 to 15 degrees…. Sunday temps will be lucky to get much above 5 to 10 degrees… Next system in the Northwesterly flow dives towards the area Sunday night into Monday… Both ECMWF and GFS are for the most part in rather good agreement on the placement of the snow and the track of said system… The track will be more South than previous systems so this would give more of the forecast area a better chance at 1-4 inches of snow… For Sunday night/Monday’s time frame…Another Arctic cold front will bear down on the area this looks to be colder than then the one this weekend…. Then another shot of snow in store for the FA for Wednesday night into early Thursday……..

TODAY..... Most cloudy with light snow moving in… Highs ranging from 18 to 24….. Winds South/Southwest light…

TONIGHT…. Cloudy snow likely see map for forecasted amounts…. Lows 5 to 10…Winds becoming Northwest 5 to 10 MPH.

SATURDAY… Mostly cloudy a few flurries here and there… Highs 10 to 15…Winds North/Northwest around 10 to 15 MPH….Lows -10 to -5

SUNDAY…. Mostly cloudy highs 5 to 10 …Sunday night light snow possible lows around -5 to 10

MONDAY…. Cloudy snow likely…. Highs middle teens… Monday night some light snow then ending lows either side of zero.

TUESDAY THROUGH WEDNESDAY…. Partly sunny cold highs 0 to 10 Lows -20 to -10… Slight chance of snow for Wednesday night….

THURSDAY THROUGH FRIDAY…. Partly cloudy may be some light snow of Friday we will have to watch for that… Highs in the single digits to lower teens lows -15 to +5.

Next chance of snow comes back into the forecast on the 23/24 time frame per 00z computer model runs… The track of this as of right now would put the heavier snow just South of the FA… Next system hits around the 26th as WAA kicks in… Temps do warm to near norms by the 26 and 27th before another Arctic front dives Southwards … With that there will be another shot of light snow the 27/28th time frame… Next system moves in for the late 29/30th time frame… So to recap the longer term….. Off and on light snows and temps will be up and down as well….. No big winter storms or no big warm ups in the this forecast cycle, as the Northwesterly flow keeps alive for most of this time frame….
