Severe Storm Watch. SPC has issued a watch for most of central and east central Minnesota and a big chunk of western Wisconsin until 6 am. There's a good chance the cells over western and central MN will congeal into an MCS, a swirl of strong to severe storms capable of torrential rains, 50-60 mph gusts and frequent lightning overnight. I could see some minor flooding as the storms sweep thru, probably making for a slower Friday morning commute.

If you are heading out to any Aquatennial events during the afternoon/evening Saturday, you might want to pay attention to the weather as severe storms will be possible. Click through for more details. - D.J. Kayser
Thursday was an acquired taste: 95 with a heat index close to 105F across much of the MSP metro area. Today will be nearly as hot, but relief is showing up on the horizon. We may have to dodge a few hail-spitting T-storms Saturday, but by Sunday cooler, less humid air pushes southward out of Canada.
Today will be oppressive, miserable and vaguely awe-inspiring. After shivering half the year it's amazing (at least to me) that it can get this hot in Minnesota....ever. There's a shot at 100-degree air temperatures in the metro area with a dew point of 80F, making it feel like 110 to 115F. This is about as nasty as it gets - dew points drop a notch Friday and by Sunday we'll all be breathing easier...
The next 72 hours will be an acquired taste. At some point you may scratch your head and wonder (out loud) how it can possibly get this hot at our northerly latitude. A wave of incandescent heat arrives today, peaks Thursday, and then recedes over the weekend. Thursday evening heat indices may top 110F, increasing the risk of spontaneous combustion. Be careful out there.
Monday was about as pleasant as it's going to be this week. Humidity levels go up a notch today with highs near 90F, an influx of heat sparking a few T-storms later today into early Wednesday. And then the serious heat arrives with heat indices as high as 105-115 Wednesday into Thursday. Friday should be the last beastly-hot day; a wind shift to the north bringing welcome relief to Minnesota over the weekend.
