September 18, 1997: An F3 Tornado destroyed several buildings and numerous others damaged. Hundreds of trees were knocked down. A number of cattle were also killed in a barn that collapsed.

Warming Up Again Next Week - MSP Rainfall Record Thursday
"A bank is a place where they lend you an umbrella in fair weather and ask for it back when it begins to rain" wrote Robert Frost. Yes, I've found many banks are happy to lend you money - if you don't really need it.

Meteorological summer was the hottest since global records began in 1879. All that heat that's been going into the oceans is starting to juice the atmosphere; the El Nino now brewing in the Pacific may be one of the strongest on record.
Which is a long way of saying September will be considerably warmer than average across Minnesota. After cooling off today 70s return next week; GFS model data hinting at more 80s about 8-10 days from now.
The ECMWF ("Euro") had the right idea clearing us out late tonight. All the models show a cool, sunny Saturday. Take a light jacket to the Gophers game.
After yesterday's monsoon rains (a record 2.37" fell at MSP) it's a relief tracking a dry, comfortable weekend.
Mild Bias into Late September. NOAA's GFS model, looking out 10 days (above) shows a few residual showers later today, instability showers but nothing severe expected, followed by weekend clearing. A warm frontal boundary sparks a few T-storms the latter half of next week; GFS guidance is still hinting at a few 80s the last weekend of September. More July than September.
The Planet Set 3 Major Heat Records in August. Joe Romm has the sweaty details at ThinkProgress; here's a clip: "Like a broken record, we are breaking records for temperature over and over and over again.
