Quick snow update...perhaps larger system on the way?

The first snowfall of the season has officially arrived in MN, ahead of schedule. The snow line was supposed to be in Western Wisconsin around the noon hour on Saturday, but the front has decided to increase in speed, putting the snow band in Western WI around the 2am time frame. Below is a radar image of where the snow is, as of 11:20pm on Friday night, as well as the cold front position, and the current Freeze Warnings for SE MN and SW WI.



A much larger system appears to be on the way to Minnesota and Wisconsin on Sunday, bringing a mix of rain and snow to the area. There are still many uncertainties with this system, including exactly where the rain/snow line will line up, how far north the low will travel, and how much snow will be able to accumulate with the ground not yet frozen. At this point, the HPC is forecasting a pretty good chance of accumulating snows across Minnesota, with the highest likely hood being to areas north and west of the Twin Cities. Below is a graphic of the likely hood of seeing at least 4 inches of snow from the system. Areas shaded in blue are a slight risk (10%), green a moderate risk (40%), and red a high risk (70%) of receiving at least 4 inches of snow. Lots still up in the air, and a lot will likely change, but stay tuned!
