Expect some more lake effect snow showers for the North Shore and Duluth throughout the night tonight. Our next big system is to our south, around Missouri. Since it is to our south we will continue to have an eastern flow, out of the ENE at 5-20mph. So some gusty winds can be expected. There’s a 40% chance of some flurries tonight with lake effect wrapped up into that.
A large low pressure system moves over Indianapolis and brings a swath of snow to the north by the morning hours Tuesday to the Northland. Heaviest snow is south and east of Duluth in NW Wisconsin. By lunch time the snow moves north to the Iron Range and I. Falls. The heaviest snow is falling east of Ashland as the low sits over Dayton, OH. Aloft there’s a large trough in the jet stream that helps create uplift to keep us under some snow as well. A nice big upper level low develops over the region and pushes to just over Milwaukee by the evening. Snow showers end from west to east during the late afternoon to early evening. The center of the surface low sits over Detroit. Winds are out of the northeast and are still rather strong with a flow around 5-20mph.
Overnight into Wednesday the low moves north into Ontario. We have some light snow showers east of Duluth and steady snow around the U.P. By 6am Wednesday it looks like the snow is out of the region, except for some light flurries for the U.P.
As far as snow totals go expect around a half inch to 3” for the Iron Range, Ely, and I. Falls; 3-6” for Silver Bay, Grand Marais, Duluth, Aitkin, Hayward, and Ashland; 4-8” around Ironwood, Mercer and Price County.
Wednesday morning we have temps in the upper single digits, around 9. By the afternoon we get up to 21 with mostly cloudy skies.
Thursday a shortwave in the jet stream is pushing through the area. High pressure sits over the Dakotas and a low is down to our south in Oklahoma. Expect mostly cloudy skies with lows down to 10 and highs up to 18. Colder air is coming in from the north and is the cause of the clouds. This cold air also brings a 20% chance of flurries.
FRIDAY & SATURDAY:
The high pressure system moves into Minnesota and this clears us up and we stay chilly. Lows are near 1 and high temps are near 15. Saturday is similar with morning lows near 2 and highs reaching 16. Skies have a few more clouds as an upper level low nears from the west.
