A fairly tranquil weather pattern will be in place across the upper Midwest over the next few days as an upper-level ridge moves east out of the northern Rockies later this week, but first there will be an upper-level trough and a cold front which will move through the area on Thanksgiving, but the majority of the energy with this system will dig S/SE through the Rockies and into the southern Plains through the end of the week before this system ejects NE this weekend.
Note: Patchy low clouds and fog are possible in the Northland tonight-early Wednesday morning, but a greater potential for fog/low clouds exists for Wednesday night through Thanksgiving Day.
European model 500mb height anomaly forecast valid November 23 thru November 27, 2022.
Ridging – Red
Troughs – Blue/Purple
This is incredible!
Check out the temperature anomaly over the past 7 days.
Nearly the entire Lower 48 has been colder than average over the past 7 days, with the blue and purple areas representing temperature anomalies of -10 F or greater!
We’ve had more below average days vs. above average days in Duluth this month but will likely add to the number of above average days the rest of this month.
A change in the weather pattern is possible for next week which may lead to some snow or rain returning to the Northland as a few systems move out of the Rockies.
Whether or not we see any significant storm develop next week is highly uncertain, but the potential is there for a larger storm to impact parts of the northern Plains, upper Midwest and western Great Lakes sometime next week.
CFS model is trending colder and colder for December across the northern U.S.
