Looks like far northern Minnesota could see the least amount of precip this week with amounts ranging from around a tenth to quarter inch possible, while farther south/east precip totals of one half to one inch are possible by Friday in northeast Minnesota and northwest Wisconsin with locally higher amounts in eastern Minnesota and northwest Wisconsin the way it looks now.
18z NAM 3km model 4-14-19
Radar forecast valid from 7 AM Monday to 10 PM Monday.
A few showers are possible Monday, especially during the afternoon and evening hours in north-central and northeast Minnesota into far northwest Wisconsin. No heavy downpours are expected, and some locations will remain dry through the day!
Watching another storm which may affect parts of the Northland mid to late week. There is some uncertainty on how this system will evolve later this week so check back for updates.
•Potential storm tracks (black lines on map)
•Precipitation starts as rain Wednesday.
•Rain or a rain/snow mix Thursday and Friday with a chance for the precipitation to become all snow at times late this week.
•Low chance for some snow accumulation late Thursday into Friday in parts of northeast Minnesota and northwest Wisconsin (blue outlined area on map)
•Temperatures don’t look nearly as cold as they were with last week’s storm, but enough cold air could wrap into the north/west side of the surface low to cause a rain/snow mix or a changeover to all snow. If precipitation rates are heavy enough and the dynamics strong enough, that could help mix down colder air leading to a changeover from rain to snow for some of us late this week.

Weather Synopsis for Northeast Minnesota and Northwest Wisconsin
A nice end to the weekend with copious amounts of sunshine. Highs were generally in the middle 40s which is a little cooler than normal for April 14th. Increasing east winds due to a low pressure system well to our southeast over Ohio led to cooler temps in the 30s to around 40 degrees near Lake Superior today.
Tonight: Clear to partly cloudy skies with a wide range in overnight lows from the teens and possibly even some single digits in the typical cold spots around the area to the 20s elsewhere.
Monday: Partly to mostly cloudy with a few showers possible in parts of the area mainly during the afternoon-evening. Low pressure and warm front approaching from the northern Plains will be responsible for the increase in clouds Monday and the potential for a few showers. Highs will be in the 40s to around 50 degrees with cooler 30s along the North Shore of Lake Superior.
Tuesday: Partly to mostly sunny. Warming up with highs in the 50s, possibly even a few 60 degree temps.
Note: A cooling trend mid to late week with possible rain, and perhaps some snow or a rain/snow mix by Thursday or Friday.
