Few Morning Rain Showers, Then a Dry Weekend
However, the next storm system has again triggered showers and thunderstorms from the Dakotas into western Nebraska and Kansas (see infrared loop from College
of DuPage Satellite and Radar Menu). The storms produced several incidents of 60-75 MPH wind gusts in western and central South Dakota, closing parts of I-90 for a while last evening as several trucks and campers were blown over.
Those storms have pushed into eastern Nebraska during the early morning hours (see NWS
Upper Mississippi Valley radar loop).
There is a cold front pushing through North Dakota and northwestern Minnesota (see NWS
WPC Latest North American zoom-in surface map). The cause is a strong low pressure system moving southward in Manitoba (see counterclockwise circulation on water vapor loop from College
of DuPage Satellite and Radar Menu). The northwest to southeast motion means that the area with the best lift and moisture that triggered yesterday's storms will mostly stay to our south. However, when the front comes through this morning, we will have a lot of clouds and a good chance of a few scattered showers and perhaps even a thunderstorm. I don't expect any severe weather or any heavy rainfall from this system.
The storms may tend to regenerate this afternoon over the southern third of Minnesota, but we should see mixed clouds and sun this afternoon, a strong northwest wind, and drier air. After a cool start due to all of the clouds, highs should still make it into the upper half of the 70's to near 80.
The drier air from Canada will again surge in behind this cold front and dominate our weather through the weekend. I'm a bit more optimistic about the later portions of the holiday weekend. The latest forecasts have the new storm in northern California (counterclockwise rotating swirl on the water vapor loop from College
of DuPage Satellite and Radar Menu) tracking through the central Rockies and then the Plains of Kansas into Missouri. That should leave the northern extent of the rainfall no closer to us than southern Iowa. If this works out, look for sunny days with highs in the low to middle 70's tomorrow, in the upper 70's Saturday and Sunday, and near 80 on Monday. Lows will be in the lower 50's and even the middle to upper 40's.
Weather systems will begin to more from west to east across the northern half of the US next week. That would set us up for more frequent chances for rain and changeable conditions.
With one day to go, June will end up being a warmer-than-average (temperature 67.5°F, 2.2°F above average through Tuesday) and drier than average (3.28 inches through Tuesday, about 0.7 inch below average with some rain possible today) month. However, St. Cloud is on the edge of drier conditions through Benton and especially Mille Lacs Counties (less than 3 inches of rain) and wetter conditions in central Stearns, Kandiyohi and Meeker Counties (more than 5 inches of rain for the month). The part of Minnesota that is badly short of rain is near Lake Traverse, Lac qui Parle, and the South Dakota border near Ortonville and Madison with less than 2 inches of rain. Northwestern and north central Minnesota have seen more than 7 inches of rain with over 10 inches of rain in Koochiching County.
