*Image below is what the 12z GFS model is showing in terms of snowfall accumulation for Monday-Wednesday. More details below…
…Possible snow and or mixed precipitation event setting up for December 2-4…
-12z model data is in and it does support some wintry weather across the Northland. The computer models are not in the best agreement though on the track and speed of this weather system, but a consensus between the GFS and NAM would be for most of the precipitation to take place from Monday Evening into early Wednesday, although the CANADIAN model would linger precipitation all the way through Thursday due to a different scenario shown compared to the NAM and GFS models.
-At this time I’m thinking much of Northeast Minnesota and Northwest Wisconsin could pick up 4″+ of snow with 6″+ of accumulation most likely along the North Shore of Lake Superior where easterly winds result in some lake enhanced snowfall next Tuesday. Note: The snowfall totals I mentioned in this post are very preliminary and could easily increase or decrease during the next few days.
-The possibility also exists for a wintry mix of precipitation on Tuesday, mainly over East Central Minnesota and Northwest Wisconsin, although the amount of ice that could accumulate (if freezing rain does fall) is highly uncertain at the moment.
Stay tuned to later forecasts/updates in coming days. Winter weather headlines may be needed for portions of the Northland during the early-middle part of this coming week.
Note: The Lezak Recurring Cycle or LRC targeted Today’s date (November 30) for a significant snowfall. M1 and M2 7.2″ of snow. M3 14.4″ of snow. Mean: 9.6″. Remember plus/minus a day, so perhaps December 3 would be the day should the current forecast models verify.
