Breezy and cool with a few showers; snow flurries and graupel showers possible late this week

A mid level low pressure system has been making its way S-SE through the upper Midwest today, this system brought a few rain showers to parts of northeast Minnesota and northwest Wisconsin today.

Here’s a look at today’s low pressure system cutting through Minnesota as seen on water vapor imagery.

Isolated showers have been moving south-southeast across parts of the Northland today, but these showers haven’t lasted very long, so they aren’t producing a whole lot of rainfall.

We should see a few more showers in our area Tuesday and Wednesday, but with many dry hours mixed in, and any rain that does fall shouldn’t amount to very much. Note: It looks like September 2020 will finish as the 6th or 7th driest September on record at Duluth, Minnesota with just 0.81″ of precipitation so far this month, and not a whole lot more expected thru Wednesday (30th)

Monday afternoon temperatures ranged from the upper 40s to middle 50s across the Northland which is below normal for late September as our normal highs are right around 60 degrees.

Highs on Tuesday will range from the upper 40s to lower 60s, with highs Wednesday in the upper 40s to upper 50s.

Even colder temperatures are on the way for late in the week, and the source region for this cold air will be coming from way up north in the Arctic regions of Canada, but with it being so early in the season this air mass will modify a good 20 degrees or so once it reaches the Northland later this week, so instead of temperatures in the 10s and 20s we’re looking at temperatures in the upper 30s to upper 40s for Thursday, Friday and Saturday.

With the colder temperatures for late this week, there will be a chance that some parts of the Northland will see some snow flurries and graupel showers (soft hail/snow pellets) in the Thursday-Friday time frame.

Seeing some differences in the weather models on next week’s pattern.

The euro ensemble model (EPS) has a ridge setting up further east resulting in a warmer pattern for the Northland (daytime highs 60 degrees or warmer on a few days next week)

While the GEFS model keeps the ridge further off to the WSW which in turn keeps the Northland in a relatively cool pattern for next week (daytime highs in the 50s, maybe even in the 40s)
