Forecast Discussion for Northeast Minnesota and Northwest Wisconsin

Today's weather:

A cold front has turned nearly stationary from Northeast Minnesota to along the Minnesota-Wisconsin state line.  A moist and marginally unstable airmass continued along and east of that front Today with less instability behind the front in Northern and Eastern Minnesota.  Scattered showers and thunderstorms have been occurring at times Today in Northwest Wisconsin with heavy downpours, small hail, and dangerous lightning with those storms.  Warm temperatures were found in our area Today with highs in the 70s and lower 80s, but it was much cooler near the head of Lake Superior where temperatures struggled to get out of the 40s.  Dewpoints Today were in the 40s in Northern Minnesota to the 50s and lower 60s elsewhere.  Winds Today were south, north, or east under 15 mph.

Today's upper level analysis:

500mb trough covered the Rockies, Plains, and Upper Midwest per water vapor satellite imagery with an upper level ridge in place from the Ohio Valley to the Southern U.S.


A slow moving cold front will push through Northeast Minnesota This Evening and will settle south across Northwest Wisconsin during the night.  A few showers will occur in the Arrowhead of Minnesota before Midnight with scattered showers and isolated thunderstorms in Northwest Wisconsin.  No severe weather is expected Tonight, but dangerous lightning, hail to 1/2" and heavy downpours will likely accompany the thunderstorms, east of a Shell Lake to Upson, WI line.  Lows Tonight will be in the 40s and 50s with north or west winds under 15 mph.

Thursday and Thursday Night:

Low pressure will move into the Central Plains during this period.  Steadier rain and embedded thunderstorms associated with that low should stay to our south, but some showers could move through portions of Eastcentral Minnesota and Northwest Wisconsin Tomorrow and Tomorrow Night.  Partly to mostly cloudy skies are expected this period with highs Tomorrow in the 50s and 60s with lows Tomorrow Night mainly in the 40s.  Winds will be out of the north under 20 mph.

Extended Forecast:

Slow moving surface and upper level low will be moving through the Northern Plains, Upper Midwest, Great Lakes, and Central Plains from Friday into Saturday before it moves toward the Ohio Valley late in the weekend.  Showers are possible in Northern Minnesota and Northwest Wisconsin for Friday and Saturday, May 13th-14th with mainly dry conditions expected for Sunday, May 15th.  High temperatures will be in the 40s and 50s for Friday and Saturday with lows in the 30s and 40s Friday Night and Saturday Night.
