Accumulating Snowfall This Week Possible with Coldest Air of the Season

The weather leading up into the weekend felt anything but the middle of fall with a long stretch of sunny skies and temperatures in the 60s and 70s. This was all thanks to a ridge in the jet stream keeping warm air over the central part of the United States with cooler and wetter conditions along the Pacific Northwest.

This is all about to change going into the new work week. The southwest flow will change to a northwest flow with multiple rounds of storm systems passing through. The first one will be moving in overnight tonight into tomorrow. It will be gin in the form of rain but as it begins to move towards the U.P. of Michigan, it will combine with another low pressure coming in from the Gulf States. The combining force will intensify the storm Monday night into Tuesday morning.

Cold air from Canada will surge south and transition the rain into snowfall for parts of the Arrowhead and parts of the South Shore and the U.P. of Michigan. How much snowfall may fall from this system remains tricky, but a dusting to a slushy half inch to an inch is not out of the question, it will just have to snow heavily because temperatures along the surface will be near 32 degrees at best. Any snow that accumulates will quickly melt during the day on Tuesday.
Another clipper will come through on Wednesday but it will be in the form of rain. The storm system that is starting to sound the alarm for anyone who loves snowfall is the storm system Thursday into Friday. A clipper will come in from British Columbia and then move through the Dakota before passing into the Upper Great Lakes. The latest data suggests that as the center of low pressure moves over the U.P. of Michigan, the storm will intensify Thursday night into Friday. With where the Northland is positioned in relation to the storm system, there is the concern of accumulating snowfall. It is too early to determine where, how much, and if for certain there will be snow at this time since a change in the track of the storm as well as many other parameters could signify big implications to the forecast.


The FOX 21 weather team will continue to monitor these storms and keep you updated with the latest information. One key point, especially on social media, is that you are likely to see snowfall maps shared through media sites like Facebook. I highly discourage focusing on these maps as they are raw data output maps, with no forecasting intervention. Almost all the time, these raw outputs provide wrong snowfall amounts.
