Scattered showers and a few t-storms tonight, and mainly in eastern MN and northwest WI Saturday; A few lingering showers possible and cooler Sunday; Dry and warmer early next week

5:20 PM Friday, August 5, 2022

Scattered showers and some thunderstorms will be found across the Northland tonight and Saturday, but the focus for rain on Saturday should shift farther south into east-central Minnesota and northwest Wisconsin while northern Minnesota may end up mostly dry on Saturday.

A few lingering showers are also possible across the Northland on Sunday, but a widespread all-day rain is looking unlikely Sunday.

Note: A potential for a higher end rainfall event including a risk for flash flooding continues Saturday through early Sunday morning from southern Minnesota into western and central Wisconsin.

We’ve already seen an area of showers and thunderstorms move east across far northern Minnesota today (mainly north of a line from Bigfork to Ely) with heavy rain and lightning being the main threats with those storms today.

Here’s the HRRR model simulated radar forecast through 7 PM Saturday.

Note: Rain chances for Duluth and Superior look greatest later this evening through Saturday morning with most of the rain Saturday afternoon/night setting up farther south of the Twin Ports.

HREF model ensemble max is showing a swath of about 2 to 5 inches or more of rain across parts of southern Minnesota through Sunday morning.


It’s a warm early August day with temperatures in the 90s as far east as parts of western, central and eastern Minnesota, with 100s common in parts of South Dakota.

A lake wind is keeping temperatures cooler (60s and 70s) along the North Shore of Lake Superior in northeastern Minnesota today.

Cooler temperatures return this weekend with highs mainly in the 70s in the Northland on Saturday with a few 80s possible in parts of northwest Wisconsin. Highs Sunday will mainly be in the 60s. Highs get back closer to normal early next week with highs Monday in the 70s, and from the 70s to lower 80s next Tuesday.

Note: Today, Friday, August 5 marked the 19th day this year with a high temperature of at least 80 at the Duluth Airport. By this time last year, Duluth had 40 days at or above 80.

There is a corridor of very muggy air near a cold front across the eastern Dakotas and northwest Minnesota with dew points in the 70s this afternoon, but farther to the east it’s not quite as muggy with dew points generally in the upper 50s to low-mid 60s in the Northland this afternoon.

A less humid air mass will move SE out of northern Minnesota this weekend.
