This is a great time of year, with colorful blossoms on many trees. Although it’s cool today, the weather will cooperate with most outdoor plans. A brief passing sprinkle is possible in Minnesota and western Wisconsin.

Sunday afternoon highs will be in the 50s across much of Minnesota and western Wisconsin. A few spots in the Twin Cities metro area and southeastern Minnesota could touch 60 degrees. For reference, our average Twin Cities high temp is 71 degrees this time of year.

Low temps late Sunday night and early Monday morning are forecast to reach the 30s in roughly the northern half of Minnesota plus western Wisconsin:
