A winter weather advisory is in effect for tonight for the Arrowhead of Minnesota including the cities of Isabella, Forest Center, Tofte, Lutsen, Grand Marais, Hovland and Grand Portage. Plan on slippery road conditions which will develop this evening and continue through the overnight due to accumulating snow and temperatures falling below freezing. Wind gusts to 35 mph are also expected which could lead to some patchy blowing snow.
Here’s my snowfall forecast through 12 PM Monday.
Radar loop from 3 PM to 4:50 PM Sunday, April 18, 2021. Note: The Duluth radar is out of service until April 21st due to maintenance.
- Rain changes to snow and flurries across the Northland from NW-SE tonight.
- Scattered snow showers and flurries are possible Monday and Tuesday, but we should also see some sun from time to time.

A strong cold front is on the move this afternoon, with 30s behind the front and 50s and 60s ahead of the front.
Expect highs in the 30s to around 40 in northeast Minnesota and northwest Wisconsin Monday, Tuesday and Wednesday which is roughly 15 to 20 degrees colder than normal for mid April. Note: Looks like will warm up to normal levels late this week with highs getting back into the 50s and lower 60s for Thursday and Friday.
A fairly potent system continues to dig south/east into northern Minnesota this afternoon, but this system is moving through pretty quickly, but it will help pull colder air south into our area over the next few days.
Water vapor loop from Sunday, April 18, 2021.
