We’re making progress.
The Saturday afternoon high temp at Minneapolis-St. Paul International Airport was 22 degrees. That was still 9 degrees shy of our average Feb. 20 high temp in the Twin Cities, but it was a full 25 degrees warmer than the -3 degree high temp that we saw last Saturday.
The upward temperature trend continues Sunday and Monday.
Snow for some of us on Sunday
A low pressure system will spin moisture over parts of the upper Midwest on Sunday. Periods of snow are expected Sunday in much of southern Minnesota, the Twin Cities metro area, and parts of western Wisconsin. Heavier snow is expected in northern Iowa. Northeastern Minnesota and parts of central Minnesota may see some light snow showers at times on Sunday.
The National Oceanic and Atmospheric Administration’s North American Mesoscale (NAM) forecast model shows the potential precipitation pattern for Sunday morning through Sunday evening:
