Regional View
Note: The regional view map has been change, I realised after the fact that Mondays system had the potential to bring Blizzard conditions to southern Minnesota, not Fridays, It is difficult to keep up with all these systems.
An extremely active pattern has set up, active enough that the Upper Midwest is getting hit with system after system. The next system is targeting the Upper Midwest Friday and Saturday. Minor snowfall accumulations are expected across Minnesota and Northern/Western Wisconsin. With significant lake enhanced snow effecting Northeast Wisconsin and the Western U.P of Michigan. Cold arctic air will plunge south behind the system for Sunday.
Local View
Locally we can expect that the next system will not move in until later Friday evening. so Expect a cloudy Friday with maybe some left over flurries early from Thursdays snow. then late Friday/Friday night, we can expect snow to move in. Snow will last through the night into Saturday Morning, and some of it will be moderate to possibly heavy at times highs will be in the upper teens. Light snow will last into the 1st part of Saturday before turning to flurries. Colder air will follow the system and it will be moving in starting Saturday, on windy Northwest winds. Blowing snow could be an issue with cold wind chills highs will be in the low teens with lows in the single digits below zero. Sunday will be partly cloudy and cold with lighter winds. Highs will be in the single digits with lows depending on cloud cover. We could have single digits for lows, or lows around 10 below zero.
Accumulatiuons
Accumulations from this system will me mainly on the minor side, but will be the highest we’ve seen in a few Weeks. The highest accumulations will likely in the Northeast areas, where 2-4″ of snow will fall. the rest of the area will see 1-3″ Keep in mind a and shift could effect these totals.
Friday, Cloudy with snow developing in the evening. Highs in the upper teens. Friday Night, Snow, some could be moderate to possibly heavy at times. Lows in the upper single digits
Saturday, Snow turning to flurries Colder and windy conditions and cold wind chills. Total system accumulation 1-4- entire area. Highs in the low teens. Saturday Night, Clearing, partly cloudy with lows in the low single digits below zero.
Sunday, Partly Cloudy and Cold, highs in the single digits. Sunday Night, turning Cloudy with flurries possible. Lows in the low single digits.
Looking Ahead
Monday looks quiet and cold as we get a brief break, and I really mean brief because by Tuesday another system with possible minor accumulations. Wednesday very cold air follows behind the system, which is some of the cold air I’ve talked about in previous forecast issues. Highs might not get very far above zero with lows falling well below zero. This cold snap looks short lived as the next system comes in by Thursday the 20th, again minor accumulations look possible. Warmer conditions with another possible snow system moves in for the 23rd but it appears to look light. Towards the end of the mode run the models are having trouble trying to detect a possible warm up. Because of this I will not have a word on it yet. more on this later.
