A bit warmer today compared to the last few days with Thursday afternoon temperatures in the Northland generally in the lower to middle 60s which is still roughly 5 degrees below normal for mid-September, but overall not bad compared to the last few days.
Highs on Friday should mainly be in the 60s, but then temps trend cooler on Saturday due to the clouds and some rain, highs in the 50s and lower 60s on Saturday.
Warmer temperatures in the 70s were found further off to our northwest today, but unfortunately those 70s won’t be making it into our area at least through the weekend, but we could see 1 or 2 days next week with highs close to 70 or into the 70s, the most likely day/s for that to happen would be next Tuesday and or Wednesday.

A rather strong mid to upper level low pressure system continues to spin slowly ENE into Colorado today. This system will track northeast into the upper Midwest Friday night into Saturday, but it won’t stick around long as it gets picked up by stronger winds aloft (jet stream) once it reaches the upper Midwest on Saturday.

Here’s the rainfall forecast for Friday night and Saturday.
Looks like a good portion of the Northland will get at least a half inch of rain out of this system, but higher amounts approaching an inch are possible along and east of a line from around Siren to Ashland. The least amount of rain looks like it will be over far northwest portions of the Northland, around the International Falls area where rain totals of around a tenth of an inch or less are expected.
As for the timing of this rain for Duluth and Superior: Looks dry through the day Friday and thru most of Friday evening. Rain is expected to move in from the southwest late Friday night-early Saturday morning (11 PM to 1 AM time frame) Some rain is expected to continue thru most of the day Saturday, then the rain ends Saturday night. Sunday looks dry.

This is pretty wild!
It still looks like will see some smoke lift northeast into Minnesota Friday and Saturday due to the system coming out of Colorado. The wind field around this low will allow some smoke to get carried NE ahead of the low, then on the backside of the low will see some smoke move toward the west and south. This smoke is expected to remain in the mid to upper levels of the atmosphere with no real impacts expected near the surface, so the main issue could be some haze due to the smoke, and perhaps a vibrant sunset Friday evening (if it doesn’t get cloudy by then)
