There’s a giant low pressure system moving into Wisconsin tonight. As it nears our winds will actually decrease a bit. A large swath of rain pushes into Minnesota before moving down into NW Wisconsin by the early morning hours. The winds shift tonight to a more NW flow at 15-25mph with gusts up to 35mph by the late evening hours to a NW flow at 5-15mph by the early morning. There’s not as tight of a gradient as the low moves over Lake Superior. Temperatures are in the upper 30s to low 40s across the region. A few locations near the lake will be in the mid 40s.
Our low pressure system weakens as it moves over Lake Superior on Tuesday. We have a northwest wind at 15-25mph with gusts up to 35mph and temperatures drop as the cold front passes through the region. So expect temps in the mid 40s by the morning and upper 30s by the evening hours. Expect a 70% chance of rain showers throughout the day with cloudy skies.
The clouds stick around on Wednesday. We have an upper level trough that provides enough uplift to warrant the cloud coverage and also keep us chilly. Morning lows are in the mid 30s and highs reach the low 40s.
We have more sunshine on Thursday. A weak ridge in the jet stream will help clear us up, but cold air is still in place. Morning lows are in the low 30s and highs reach the low 40s again.
Warm air is moving in by Friday. Lows are down to 30 and highs reach 49. Expect a few more clouds with the warm air (partly cloudy).
There’s a large low pressure system to the north over Lake Winnipeg on Saturday. This funnels in warm air from the south. Morning lows are in the mid 30s and highs reach the mid to upper 50s. Skies should be mostly sunny.
