A few showers are possible later tonight into Saturday morning in eastern Minnesota and far northwest Wisconsin with a steadier rain possible Saturday farther east across portions of central and northern Wisconsin.
18z NAM-Nest model radar forecast valid from 7 PM Friday to 7 PM Saturday.
Here’s the 12z European computer model rainfall forecast through Saturday afternoon. Highest totals stretching from far southeast Minnesota through central Wisconsin into western Upper Michigan. Note: A few computer models show the higher rain totals a little farther west compared to the Euro, but all the models keep the bulk of the rain east of Duluth and Superior late tonight and Saturday.
Another beautiful fall day with temperatures this Friday afternoon running 5-10 degrees warmer in most areas compared to Thursday afternoon. Almost summer like today from Brainerd and St. Cloud south to Mankato where highs climbed into the middle 60s to lower 70s today.
Computer models agree that a rainy system will hit the Northland early next week, but models disagree on the storm track. The Euro camp is farther east with the low, taking it through western-northern Wisconsin while the GEFS model has a farther west storm track from southwest Minnesota to near Thunder Bay.
Note: Temperatures look warm enough for precipitation to fall as rain with this storm early next week.

High temperature forecast for Saturday, October 19
A cold front will move west to east across the Northland late tonight through Saturday. Some showers will develop as this front moves through, with the best chance for some rain in eastern Minnesota and northwest Wisconsin.
Temperatures will be relatively mild tonight considering the time of year, you can thank increasing cloudiness and a southerly wind for the ‘mild’ temps tonight, speaking of those south winds, they will be cranking tonight with a low level jet of 40 to 60 knots ahead of the eastward moving cold front. Lows tonight will range from the lower 40s to lower 50s.
Mostly cloudy skies on Saturday but we should see some clearing develop from west to east through the day. Rain chances are greatest in parts of northern Wisconsin with a slight chance for isolated showers Saturday afternoon across far northern Minnesota. Highs Saturday will range from the lower 50s to lower 60s with the coolest temps over northwest Wisconsin as that area looks to stay mostly cloudy for most of the day. Winds on Saturday will be out of the southwest at 10 to 20 mph.
Mainly dry on Sunday with partly to mostly cloudy skies. Highs will be in the 40s and 50s.
Rain chances increase Sunday night, but there are some trends showing up in model guidance for a slower arrival to the rain, so it may not be until Monday before we begin to get some rain in the Northland, rain is then forecast to continue Monday night into Tuesday, although some parts of the area could be affected by a dry slot for a few hours late Monday which would shut off the rain, but where this dry slot ends up will depend on the storm track.
Colder temperatures move in behind this storm for the middle to end of next week with high temps in the 30s and 40s from October 23-25.
