Goes-16 visible satellite loop from Friday, May 24, 2019.
A well defined low pressure system passing through the Northern Plains and upper Midwest today. Note: Highest rainfall amounts with today’s storm have been across northern Minnesota.
Low temperature forecast for Saturday morning, May 25.
Near normal to above normal lows tonight in the lower 40s to lower 50s but it will be cooler near Lake Superior with lows in the upper 30s.
High temperature forecast for Saturday, May 25.
Milder temperatures on Saturday with highs ranging from the lower 60s to lower 70s, warmest temps in northwest Wisconsin and eastern Minnesota, normal highs in late May are in the mid to upper 60s, so these highs on Saturday resemble more typical late May temps in our area, except in northern Minnesota where forecast highs are roughly 5 degrees cooler than normal for May 25.
Rain is possible across parts of the Northland early next week (Monday-Wednesday time frame)

Well this would certainly be the icing on the cake in what has been a lousy spring across the upper Midwest, check out this 500mb forecast which goes from May 26 through June 3. An unusually strong upper level low (similar to a Polar Vortex) digs south/east into Hudson Bay and Ontario province during the middle/end of next week, and once it reaches those areas it may stick around a while, what this will do is cause a cool NW flow across the upper Midwest into the first few days of June. Note: If the upper low digs farther south, temps will be even cooler later next week in our area, but if this upper low ends up farther northeast, then milder temps would occur across the upper Midwest, that latter solution seems unlikely given how this spring has been around here. Stay tuned.
