* 97 F. reported at St. James and Cambridge Monday afternoon, hottest in the state.
* Atmosphere remains "capped" over Minnesota Monday, too dry/hot aloft for T-storms to pop - later Tuesday the cap will break, and the risk of thunder will increase (but SPC is not expecting a widespread severe storm outbreak).
* Hot, dry, desert-winds gust over 40 mph.

* 1.5" diameter hail reported from storms over far northern MN Monday, damaging rooftops, skylights, stripping leaves off trees.
* 90 possible again today, dew points close to 70 will make it feel like mid 90s.
* Strong T-storms possible late Tuesday as a cooler front approaches (probably not a widespread severe weather outbreak).
* Wind shift to the north/northwest pumps cooler, drier Canadian air into Minnesota - by late Thursday the air overhead will have HALF as much water as it does right now.



Enjoying May? Summer came swirling into Minnesota, right on schedule on Monday, boosting temperatures to record-levels, 20-30 degrees above average across the state. Yesterday felt like something right out of the Dog Days of early August, an exclamation coming at the end of our fast-forward spring.
Today won't be quite as hot, but if the sun stays out for a few hours during the morning and midday hours (likely) we stand a very good chance of hitting 90 once again. Throw in a dew point in the mid to upper 60s and the THI, the temperature-humidity index will reach the mid 90s, reaching into the danger zone. Take it easy out there today; the good news: a cooler front arrives Wednesday as winds shift around to the north, the worst of this oppressively muggy airmass will get shoved towards Milwaukee and Chicago, and we'll finally be breathing easier again. I expect a 20-30 degree drop in dew point by Friday, meaning that by the end of the week there will be approximately HALF as much water in the air (for every 20 degree drop in dew point the amount of water vapor drops by roughly 50%)

Good news indeed.
Now, about that major holiday weekend on the way:
