The final days of the Minnesota State Fair should be pretty nice, although there is a chance for showers Saturday before a gorgeous Sunday and a tolerable Monday.
Tolerable? Monday is going to be warmer with high temps around 80 degrees, along with much higher humidity and dewpoints into the 60s and possible around 70, which is tropical. All of that heat and moisture will set the stage for potential severe weather.
As of Saturday, the Storm Prediction Center (SPC) has placed a massive chunk of Minnesota, including the Twin Cities, in a slight risk for severe storms. The SPC notes that the risk area is "highly conditional" and will certainly be adjusted over the next 72 hours.
The idea at this point is for storms to fire up in eastern North Dakota around the dinner hours Monday and for the storms to congeal into a line and surge east-southeast through Minnesota late Monday into the overnight hours to Tuesday morning.
The National Weather Service in the Twin Cities says damaging winds and large hail are the main threats, but a tornado or two can't be ruled out, "especially across central MN" where a warm front will be in place.
Based on model guidance, it appears the best chance for storms will along and north of Interstate 94, which is why the southern extent of the slight risk zone is highly conditional.
The rest of the week looks to be cooler and drier, according to the weather service, which goes as far as mentioning potential for FROST late in the week in parts of central and eastern Minnesota.
