Deep freeze! Temperatures this Monday afternoon, October 26th, 2020 are running 30 to 50 degrees below normal across the central US.
Freezing line all the way south to north-central Arizona, southern New Mexico into west-central Texas here in late October, while temperatures are only in the 10s this afternoon across parts of the Rockies and Western High Plains. An impressive cold shot for so early in the season.
Note: The last time the Duluth Airport was above freezing was last Friday afternoon ~5PM, October 23rd, we’ve been below freezing ever since, but this streak might end Tuesday afternoon, but more likely on Wednesday as temperatures finally climb above the freezing mark at the Duluth Airport.

No doubt about it it’s been a cold October around here, with 16/25 days or 64% of days this month having a below average temperature, while just 9/25 days or 36% of days having an above average temperature.

…Weather Summary for the Northland…
Cold and dry for now, followed by milder temps and continued dry conditions midweek into next week.
Will have a few low pressure systems with their warm fronts and cold fronts sweep through the Northland this week, but little if any measurable precipitation is expected, with only a few light showers of rain or snow across northern Minnesota late Tuesday-early Wednesday, and possibly a few snow showers across parts of the Northland on Thursday.
Lows in the single digits to around 20 degrees tonight, highs Tuesday in the 30s, but on Wednesday will get a brief spike in temps with upper 30s to mid 40s across the area. Will cool down briefly on Thursday, with highs mainly in the 30s.
Note: It does look like will have a few days near or above 50 degrees across the Northland between October 31st-November 7th, and it doesn’t look like will be seeing a whole of precipitation at least thru the first week of November, but after that things may begin to change…
