Slight Severe Risk (greatest wind/hail potential southeastern Minnesota)
July 22, 2013 — 9:41am
Slight Severe Threat. NOAA SPC has expanded the "slight risk" of severe storms later today, extending from the U.P. of Michigan across most of Wisconsin, east central and southeastern Minnesota to Des Moines and Kansas City. The greatest potential for severe weather comes in the form of large hail and 60 mph straight-line winds.
4 PM Today. The high-res HRRR model shows a developing squall line over southeastern Minnesota by late afternoon. My sense is that the severe risk is (much) higher for Albert Lea, Rochester and Winona than the immediate Twin Cities, but the metro area my see a passing shower or T-storm closer to 2-3 PM. Stay tuned...

Saturday was an acquired taste: thickening clouds and a chilling breeze - but at least it didn't snow...or flood...or tornado. Rain brushed the southern suburbs but that system moves out today and a drying northeast breeze triggers partial clearing. Temperatures mellow this week; a hint of summer warmth possible by next weekend.
Yes, there were reports of a little snow mixing in with a cold rain over west central Minnesota yesterday; temperatures in the lowest mile of the atmosphere just warm enough for rain in the metro. Things are greening up nicely and models are in agreement that it's going to warm up next week: 60s, 70s, even a shot at 80F. Spring fever returns with a vengeance next week.
I'd rather have 40s and rain than ankle-deep slush (or drought) showing up on the maps. It's supernaturally-green out there, and who can argue with a 7-month boating season again this year? Rain tapers later today with slight improvement by Friday. Saturday showers may pass just south of MSP with a warming trend next week. 70s in one week? Looks plausible...
If you liked yesterday you will love today's weather! Gray, windy and damp with another wave of showery rain pushing in from the southwest later on. The heaviest rains pass south of MSP, tapering tomorrow with a break on Friday before another band of showers arrives late Saturday. It will feel like spring again next week; if the planets align the mercury may kiss 80F the first weekend in May.
