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...

I'm happy to report that today will be even nicer than yesterday! That's a pretty low bar, granted, but we should top 80F today with some sunshine, higher humidity and a few stray T-storms. 80s will be the rule this week, with warmer than average weather spilling into Labor Day weekend. The risk of a Gulf Coast hurricane seems to be increasing again - water temperatures in the Gulf are very warm, which may fuel a big storm within a few days.
Thursday was a breath of fresh air and today will be another fine day with blue sky, light winds and no rain (amazing). Showers and T-storms return late tonight into Saturday as the atmosphere tries to warm up again - Sunday should be sunnier, warmer and drier. Summer comes rushing back next week with more 80s, even a few 90s possible by the end of next week. Hermine impacting Florida and the Gulf Coast? Still a definite maybe, but the storm is a sloppy mess; it's unclear if and when conditions will be ripe for strengthening.
So long heat index, at least for a few days. Agreeable air, courtesy of Canada, will be with us for the next few days. Clouds build up this afternoon; Friday should be sunnier with less wind and temperatures more typical of late September. After a close encounter with Saturday showers temperatures mellow Sunday and summer heat returns next week. No, we haven't seen the last 90-degree warmth.
Hard to believe it rained again last night with another fine display of thunder and lightning. At least we were spared severe storms this time around. Winds shifting to the west/northwest dry us out today with cooling temperatures into Friday (the nicest day in sight). You may need a Plan B for Saturday; with any luck we salvage a better day on Sunday. No storms with names - which is more than residents of Florida and the Gulf Coast can say. All eyes are on "Invest 99-L", which may ripen into "Hermine" in the days to come.
