Long Range Forecast for August 2022
Temperatures
Above normal temperatures are expected in northeast Minnesota and northwest Wisconsin, but Lake Superior may have something to say about that for locations along the North Shore and South Shore as water temperatures continue to run well below normal on Lake Superior.
Temperature anomaly trend for August 2022 per last 8 model runs from the CFS model.
Precipitation
Near normal to below normal precipitation is expected in northeast Minnesota and northwest Wisconsin.
Precipitation anomaly trend for August 2022 per last 8 model runs from the CFS model.
500mb height anomaly forecast for August 2022 per last 8 model runs from the CFS model.
Not a whole lot of change in the 500mb pattern compared to what we’ve already seen this summer which is a continuation of a NW flow for the upper Midwest and Great Lakes while a ridge (heat dome) covers the Rockies and Plains. Some shakeups to this pattern are possible during the month as this just shows what the average 500mb pattern should look like for August 2022.
The most intense/persistent heat in this type of pattern should remain locked up farther west/south of the Northland in August, but some shots of heat are still possible throughout the month, but the real warm stuff likely won’t stick around very long.
Thanks for reading!
