Forecast Discussion for NE Minnesota and NW Wisconsin

Short Term Forecast - Confidence:  High.

Tonight (April 13)

Clear to partly cloudy skies.  Patchy fog is possible around Lake Superior.  A warm front will remain over southern Minnesota with high pressure well to our east.  Low temperatures will be in the 30s to around 40 degrees as winds remain out of the east or southeast at 5 to 15 mph.

Thursday and Thursday night (April 14)

A warm front will wash out as it lifts N/NE out of southern Minnesota.  Partly to mostly cloudy skies are expected on Thursday.  Could be a few showers mainly in northern Minnesota but overall its looking dry in our area.  Highs will be in the 60s and 70s with 40s near Lake Superior.  Lows Thursday night will be in the 40s with 30s possible along the North Shore of Lake Superior and also in portions of northwest Wisconsin.  Winds will be out of the south or southeast at 10 to 20 mph.

Extended Forecast - Confidence:  Medium to High.

Friday through Sunday (April 15-17)

Mainly dry on Friday with highs in the 60s and 70s, lows Friday night will be in the 40s and 50s which is unseasonably mild for mid April.

A chance for showers in western-northern areas on Saturday and then further southeast for Saturday night and Sunday -- These showers will be the result of a cold front which will pass through the Northland this weekend, not expecting a lot of rain but don't be surprised if there are a few showers around either Saturday or Sunday.

High temperatures on Saturday will be in the 60s and 70s with lows Saturday night ranging from the 30s in northern Minnesota to the 40s and 50s in eastern Minnesota and northwest Wisconsin.  Highs on Sunday will be in the 40s and 50s.

Note:  High temperatures will likely remain in the 40s near Lake Superior on Friday and Saturday thanks to a persistent east or southeast wind close to the lake.

Long Range Forecast - Confidence:  Medium to High.

(April 18-23)

Mainly dry through the long range with above average temperatures.  Pretty good agreement between the EURO and GFS models today for next week, both indicate mild to warm temperatures with the warmest temperatures possibly arriving the middle or end of next week per latest model guidance.
