The Storm Prediction Center has highlighted portions of the Plains and Midwest for severe weather on Sunday. The Slight Risk covers eastern Nebraska, northern Kansas, northwestern Missouri, Iowa, southeast South Dakota, much of Missouri, Wisconsin, and the Upper Peninsula of Michigan. The most elevated risk inside this overall outlook area extends from eastern Nebraska to west-central Wisconsin.

Projected instability values off of the NAM model show figures in excess of 4000 j/kg situated from Kansas to Iowa, which should be more than enough to fire off these storms as a disturbance propagates eastward across the northern Plains. Shear from the surface to the 500mb layer looks to grow to upwards of 60 knots across the northern Plains and Upper Midwest, with spots of 70 knots also being found. It does appear that the initial storms that fire look to have some substantial tornado potential, with the aforementioned instability and shear present. As the night wears on, the expectation is for these cells to coagulate into a mesoscale convective system, which will then likely shift off to the east overnight. A strengthening nocturnal lower level jet stream should enable this eastward progression to continue.

Anonymous: I'm sure there are other places covering this event. I'll post on my own time, thank you.
Oh I hope the 4th of July is going to be nice, warm, no rain!!
Actually the 3rd thru the 6th would be heaven if it was sunny, warm, and no rain!!
You know where the Honey Creek area is!! Iowa really needs no more rain, we would be so happy to share it with CA!! Where rain is needed! And I do hope no one has to go thru those wicked tornados, wish there was no such thing.
