Tuesday& Wednesday another weather system moving up through Iowa and Illinois will spread heavy snow across parts of Iowa, Southeastern Minnesota and Central Wisconsin, this will be on the leading edge of an arctic airmass which will bring in sharply colder temperatures for Thursday.
Note: I did make an attempt to update this forecast for the upcoming storm, but I will re update this and change the maps this afternoon when data becomes more consistant. Snowstorm possible tonight then arctic air Thursday
Our next chance of rain and snow arrives Tuesday ahead of a arctic airmass. Right now snow will develop Tuesday as a low pressure system produced a very narrow corridor of heavy snow in the far east. Accumulations will be 4-6" in far eastern parts of Winona and Fillmore counties but it will be very isolated. 0.50-1.00" is possible as far west as Rochester, but west of here little to no snow accumulation. More on this later today. Wednesday will be cloudy, cold and windy. Highs will only be in the 10s with northwest winds gusting to 25MPH leading to cold wind chills. Expect lows to be below zero Wednesday Night and highs only in the single digits on Thursday
Tuesday, Drizzle changing to snow, heavy at times in the southeastern part of the area. Snow accumulations 4-6" in the far southeast. 0.50-1.00" possible from Rochester to the east. Highs in the middle 30s. Tuesday Night, Snow, Colder with a chance of light snow. Lows in the middle 10s.
Wednesday, Cold, windy with cold wind chills. Winds gusting to 35MPH Cloudy with a chance of light snow, then clearing skies. Highs in the middle 10s. Little to no snow accumulation. Wednesday Night, Clear skies and cold. Lows in the middle single digits below zero.
Looking Ahead
Looking ahead we have another shot of a significant arctic airmass which will put our highs in the single digits and lows well below zero for Thursday and Friday of this week. Saturday of next weekend a weak clipper slides southeast bringing a chance for light snows. Looking towards Sunday and Monday the 3rd and 4th things warm up nicely and remain fairly dry. Things warm up even more as we begin to approach the 8th of February. We may have several days with highs in the 30s and 40s if we have continued lack of snowcover. However towards the 11th of Febuary a strong arctic airmass building to our northwest slides southeast engulfing us in an arctic airmass and the type of weather pattern that is cold and dry with occasional systems that produce light snows every few days.
