Forecast Discussion for NE Minnesota and NW Wisconsin

Short Term Forecast - Confidence:  High.

Tonight (April 20)

Partly to mostly cloudy skies with a chance for light rain late tonight mainly over east central Minnesota and in parts of northwest Wisconsin as low pressure at the surface and aloft lift slowly east-northeast across Iowa.  Low temperatures will mainly be in the 40s to around 50 degrees with a few locations possibly dipping into the 30s in northern Minnesota.  Winds will be light and variable in direction at around 10 mph.

Thursday and Thursday night (April 21)

A cold front drops southeast through the Northland on Thursday while a surface/upper level low pressure system move east/northeast out of Iowa.  Mostly cloudy skies on the way for tomorrow with areas of showers.  High temperatures will be in the 40s and 50s with 60s possible in parts of eastern Minnesota and northwest Wisconsin if there's enough sunshine prior to mid afternoon.  Lows Thursday night will be in the 30s under partly to mostly cloudy skies.  Winds will be out of the north or northwest at 10 to 20 mph.

Extended Forecast - Confidence:  Medium.

Friday through Sunday (April 22-24)

Dry on Friday as high pressure passes through the area.  High temperatures will be in the 50s with 40s near Lake Superior; Lows Friday night will mainly be in the 30s.

The weather goes downhill a bit over the weekend, especially from Saturday night into Sunday.  Low pressure is forecast to move into the western High Plains or northern Plains this weekend with high pressure off to our north.  Rain is possible over parts of the Northland mainly from late Saturday afternoon through Sunday.  Isolated thunderstorms are also possible mostly over southern portions of the area from Saturday night into Sunday as elevated instability increases over the Upper Midwest.

High temperatures on Saturday are forecast to be in the 30s and 40s near Lake Superior and in far northern Minnesota with 50s and 60s elsewhere.  Lows Saturday night will be in the 30s and 40s with temperatures on Sunday likely holding in the 30s and 40s.  Note:  A strong wind out of the east or northeast will likely develop over the weekend near Lake Superior.

Long Range Forecast - Confidence:  Low to Medium.

(April 25-30)

The last week of April could contain some snow!  Low pressure will affect the Upper Midwest on Monday (25th)  Rain or snow is possible in parts of the area on Monday depending on how far north the moisture/precip gets -- High pressure will be off to our north which often times feeds enough dry air down into our area to keep precipitation from moving into the Northland so that'll be something to watch on the computer models during the next few days -- It looks cold enough that if precipitation moves this far north that it could be in the form of wet snow on Monday.

Another system could bring more rain or snow to parts of the Northland between the 27th-28th.

Below average temperatures are expected during the long range.
