1.8" Diameter Hail. That's what Doppler radar is estimating on the cell east of Litchfield, pushing southeast, toward Hennepin County. Time to move the party indoors (and get off the lake!) Details on the Severe Storm Warning for Wright County:

Yes, today is going to be pockmarked with puddles, a few storms may turn severe and flash flooding can't be ruled out. I'll still take that over days or weeks in a row with a heat index above 100F. Dangerous heat will spread from the central USA to the east coast by the weekend; it may feel like 110F in Washington D.C. No wonder politicians want to get out of town...
Yesterday seemed to confirm my theory that most of Minnesota probably won't have to worry about drought this summer (in stark contrast to severe drought gripping much of the Dakotas). We've seen our fair share of hot days, but our heat spikes pale in comparison to what is on tap from the Midwest to the Mid Atlantic, where the heat index may exceed 110F this weekend. It's muggy out there, but at least we see a few dribbles of Canadian air in the coming days...
Low 80s felt pretty good yesterday, about 10F cooler than Monday as a weak frontal boundary pushed just south of Minnesota, allowing slightly cooler, drier air to dribble south. Much of today looks dry, but watch for a squall line of strong to severe T-storms reaching the metro by the dinner hour. A few more waves of storms push across Minnesota into Saturday, when a cooler front of Canadian ancestry rides to the rescue. The rest of the USA should be so lucky...
Well Monday was pleasant, if you're into hot weather oppression. Low 90s, but a high dew point made it feel more like 100F in the shade by late afternoon. Louisiana with lakes, instead of bayous. Today should be just as sticky but a few degrees cooler thanks to heavy showers and T-storms in the area. A few may turn severe later on, and watch for ponding of water, even flash flooding as T-storms keep redeveloping over the same counties. A surge of comfortable air is shaping up by Sunday and Monday.
