A few snow chances ahead; mild temps Friday-Saturday followed by cooler temps Sunday-Monday; drought update

We’ve got three systems that will be impacting the upper Midwest thru early next week.

  • System one moves through Friday evening
  • System two comes through Saturday night-Sunday morning
  • System three moves through Sunday night-early Monday morning

The first system doesn’t look to produce a whole lot of precipitation, with only a few pockets of snow or mixed precipitation possible in parts of the Northland late Friday afternoon/evening, but snow accumulations look very minimal, mostly <1/2″.

The second system for Saturday night-Sunday morning has trended a little stronger in model data today, and this one could produce a swath of accumulating snow (2-4″?) somewhere in Minnesota and Wisconsin, most likely from south-central Minnesota into north-central Wisconsin, or mostly south of the Northland the way it looks now.

The third system for Sunday night-early Monday could bring another burst of snow to much of the Northland, but amounts look pretty light, maybe an inch at most.

Here’s the 18z GFS model 500mb vertical velocity forecast valid from 6 AM Friday to 6 AM Saturday.
