The hottest days of summer are still yet to come. Next week looks to fit the bill. From about Wednesday onward a stretch of 90-degree heat will take over the Twin Cities.
In case anyone is wondering the hottest day ever in Twin Cities history was 108 degrees. The longest stretch of 90-degree heat was 14 consecutive days also set during the same heat wave in 1936.
The anticipated heat wave next week could rival the heat wave of 1936 as the mid and upper level patterns are very similar. From a recent Twin Cities National Weather Service forecast discussion:
Reanalysis data for 850 mb temperatures and 500 mb heights indicate a good fit to the July heat wave in 1936. We could see some 100 degree temperatures by the time it is over. Confidence for the 100 degrees is highest across west central MN. Dew points will also be rising well into the 70s. Their rise will be aided by the evapotranspiration from the corns and bean fields. Heat indices on Thursday are already shown to be near 100 degrees. In addition, it's possible as we head into the weekend that MSP could have an overnight low or two near 80 degrees.
Over the past 7 days Minnesota has received the most rain out of any state in the Midwest. TheCuyuna Lakes Mountain Bike Trails received a whopping 7 to 8 inches in one evening. This led to considerable trail erosion and a whole lot of tree clean up as well.
The rain hasn't been all bad, however. Drought has significantly decreased across the state. Good for the lawns, gardens, and farms.
A southerly flow returns this weekend that will transport higher moisture-laden air back into Minnesota. Showers and thunderstorms will occasionally develop in response to little ripples of low pressure moving through the upper level flow over the state. Saturday night could be the wettest period in the short term with the heaviest rain falling just southwest of the Twin Cities.
