Visible satellite image from late this morning, September 5, 2017. Wildfires/Smoke ongoing over the western U.S. while Category 5 Hurricane Irma heads west toward the northern Leeward Islands later tonight-Wednesday morning — In between, a taste of fall weather occurring over the upper Midwest and western Great Lakes on this 5th day of September, 2017.
Weather Synopsis
Upper low to our east with high pressure to our west resulting in a north/northwest flow across the upper Midwest today. Very cool early September temperatures in our area this afternoon with highs ranging from 50 to 55 degrees although Brainerd managed to climb to 60 degrees, but even that is still well below average for early September. Partly sunny to mostly cloudy skies were common today with a few showers affecting parts of the area.
A cool weather pattern will continue for the next few days. Will have partly to mostly cloudy skies tonight and Wednesday. Spotty showers will continue as well through Wednesday with some lake effect rain potential for the South Shore of Lake Superior as cool temps and north winds blow over the warmer waters over the lake.
Lows tonight will be in the 40s with 30s in the typical cold spots while temperatures close to Lake Superior struggle to get below 50 degrees. Highs Wednesday ranging from around 50 to 60 degrees (Fairly similar to today)
A low pressure system dropping south/southeast from Manitoba Province could bring some rain showers to the Northland on Thursday but after that it still looks like will have a few days of dry weather (If you can believe that one) Not much warmth, however, with highs Thursday in the 50s to lower 60s. Friday’s highs are forecast to be in the 60s.
Note: There is a chance will warm into the 70s in northeast Minnesota and northwest Wisconsin from September 10-13 as winds swing around to the south. Will see if that trend continues to show up on the computer models in coming days.
