Fog potential on Thanksgiving otherwise a pretty quiet weather pattern in the Northland through the weekend; A more active pattern possible next week

5:39 PM Tuesday, November 22, 2022

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.

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.
