Weather Summary for NE Minnesota and NW Wisconsin
Date:  April 25, 2016

A windy, raw and wet day in most of the Northland as low pressure moved into southern Wisconsin.  High temperatures were only in the 30s and 40s with east or northeast winds at 10 to 20 mph with gusts from 25 to 45 mph continuing around Lake Superior where some scattered tree damage and power outages have occurred since late Sunday afternoon in and around the Duluth area.  Temperatures aloft have cooled enough in parts of far northeast Minnesota to cause the rain to mix with snow this afternoon mainly from Silver Bay to Grand Marais and along the Higher Terrain adjacent to Lake Superior.

Forecast Discussion for NE Minnesota and NW Wisconsin

Short Term Forecast - Confidence:  High.

Tonight (April 25)

Low pressure will move over the southern Great Lakes while a lingering trough remains over the Upper Midwest.  Mostly cloudy skies with lingering areas of light rain, drizzle and some wet snow tonight in parts of the Northland with low temperatures generally in the 30s.  Winds remain out of the east or northeast at 10 to 20 mph with gusts over 30 mph near Lake Superior.

Tuesday and Tuesday night (April 26)

High pressure will be centered over central Canada while the next area of low pressure heads northeast out of the central Rockies to the western High Plains -- Partly sunny to mostly cloudy skies are forecast tomorrow with highs in the 40s and 50s with 30s closer to Lake Superior.  Partly to mostly cloudy skies Tuesday night with lows mainly in the 30s.  Winds will be out of the east or northeast at 10 to 20 mph with higher gusts near Lake Superior.

Extended Forecast - Confidence:  High.

Wednesday through Friday (April 27-29)

Mid to late week will feature strong high pressure to our north while low pressure moves slowly east out of the central Plains, rain associated with that low should remain south of the Northland on Wednesday and Thursday.

High temperatures on Wednesday, Thursday and Friday are expected to be in the 40s and 50s with cooler temperatures each day near Lake Superior.  Low temperatures Wednesday night and Thursday night will be in the 30s.

Long Range Forecast - Confidence:  Medium to High.

(April 30-May 5)

There will be another low pressure system across the central Plains, Ohio Valley and into portions of the Great Lakes during the April 30-May 3 time frame -- At this time it looks like most if not all of the precipitation associated with this storm will remain south of the Northland, however, this could change if the storm track shifts north in coming days.

Below average temperatures are expected in the Northland during the long range.
