A large fast-moving trough in the jet stream is digging southward across the Northland and will allow for some cold arctic air to move into the region. The trough keeps our winds up a bit with a northwest to western flow at 5-15mph. The wind with temperatures in the teens below zero to -7 in I. Falls and -4 in Ashland. Wind chills will be around -25 to -35 and frostbite can occur in under 30 minutes.
A cold high pressure system moves southwest over southern Minnesota by Wednesday afternoon. Skies are sunny to mostly sunny. A few clouds build from the west by mid afternoon, but we will stay dry and cold throughout the day. High temps are right around 0 with -2 in Duluth, Hibbing, and Hayward and 4 closer to the lake in Ashland. Winds are out of the west at 5-10mph.
Our next low pressure system moves in from the southwest as a Colorado low. It’s on the weak side, but will still bring some light snow to the region. Overnight into Thursday morning we have a 50% chance of light snow. The snow becomes steadier by Thursday morning.
The chance of snow goes up to 60% by Thursday with it wrapping up by the afternoon. There is a concern for some lake effect snow showers in the Twin Ports during the afternoon hours as our winds are out of the northeast. Morning lows are near -3 and highs reach the mid teens.
Expect around a trace to an inch for I. Falls and just north of Ely; 1-3” for Ely, The Iron Range, Silver Bay, Duluth, Grand Rapids, and Aitkin; and 2-5” in Ashland, Hayward, and Ironwood.
But wait, there’s more! ANOTHER weak low and associated shortwave pushes over the region Friday, bringing a 50% chance of light snow showers. As of now it looks like another 1-3”. Expect cloudy skies and morning lows near 9 and highs near 20.
The low moves east and combines with a low from the southeast, and New England gets a warm wet storm out of it. For us, we have another cold blast behind the low as high pressure builds. Our temps are around 8 as we begin the day and they get into the mid to upper teens by the afternoon, but fall into the mid afternoon hours. As the cold air rushes in from the north expect a 20% chance of snow showers with mostly cloudy skies.
Sunday is cold too. Morning lows are near -8 and highs reach 7 with partly cloudy skies as the high pressure system sits over Southern Minnesota.
