Everything remains on track regarding the pattern and the prospects of an Arctic airmass impacting the Northland this weekend into next week, but there have been some changes in model guidance regarding the duration of the most extreme cold, which looks to hit early next week with the potential for milder temperatures to arrive mid to late next week.
Highs Sunday and Monday are forecasted to be in the single digits and teens below zero in the Northland with lows in the teens and 20s below zero Saturday night through Monday night with a shot at 30s below zero in the typical cold spots across northern Minnesota. Wind chill temperatures in the -30s and -40s are looking quite likely in the Northland this weekend and early next week.
Prior to the arrival of arctic air this weekend, we have a little more snow in the forecast as two systems cross the region.
On Wednesday, a warm front advancing east from the Dakotas will generate some snow in the Northland, along with gusty winds out of the south-southwest, which could lead to some patchy blowing snow during the afternoon.
Note: We’ll see some pretty good warming occur in the Northland on Wednesday, with early morning temperatures in the single digits and teens below zero, rising to the 20s and lower 30s Wednesday night.
Another clipper passing north of our area on Friday could produce a few more snow showers across the area.
NAM 3km model simulated radar forecast valid 7 AM Wednesday to 7 AM Thursday.
Some parts of the Northland could see around 1 to 2 inches of snow from Wednesday into early Thursday.
Duluth area: Up to an inch of snow is possible mainly Wednesday afternoon. Patchy blowing snow is also possible as south to southwest winds increase, with gusts of 20 to 30 mph.
Here’s the temperature anomaly forecast from the Euro Ensemble model for next Monday.
All of the blue, green, and purple colors represent below-normal temperatures. Widespread cold, Arctic air early next week.
850 mb temperatures look to bottom out around -30 to -32°C in the Northland on Sunday and Monday, which puts the standardized anomaly at around -2.5 sigma per GFS model.
Later this month, computer models have been hinting at the upper-level pattern reversing with lowering heights and colder air setting up over the western U.S., while rising heights and milder temperatures develop from the southern to eastern U.S. This type of pattern could increase the chances of a more active, possibly wintry pattern developing in the upper Midwest later this month.
