Growing Risk of MCS System - Wind Damage, Flooding Rains Possible
June 16, 2014 — 2:40pm
Developing MCS System? It's still a bit premature, but ingredients seem to be converging for a possible meso-convective system, a large surge of strong to severe thunderstorms which will impact much of central and southern Minnesota into the late evening hours. A Tornado Watch is posted for southwestern MN until 8 PM, conditions most ripe for tornadic supercell storms either side of the I-90 corridor. NWS Doppler at 2:38 PM.
Straight-Line Wind Potential. NOAA's HRRR model, valid at 8 PM, shows T-storms with potentially strong to severe straight-line winds approaching the metro, the greatest potential for wind damage just south of MSP, but it may be a close call.
Ripe For Flash Flooding. NOAA models show rainfall rates as high as 2"/hour possible with some of the storms pushing into central and southern Minnesota. Heavy rain falling on saturated soil will result in rapid run-off and a high risk of flash flooding into the overnight hours.

Friday was hard to love, weatherwise. Then again, November is the cloudiest, dreariest month of the year in Minnesota. A quiet weekend is shaping up with highs in the 30s; the best chance of a rare sunshine sighting on Sunday. 50F is not out of the question next Monday; again Friday of next week (Black Friday). Yes, I'll be power-shopping for a not-as-cold-front. Still no big storms brewing looking out 1-2 weeks.
No weather drama between now and the weekend after Thanksgiving, not close to home. Stormy weather is likely over the Pacific Northwest and New England, but a stubborn ridge of high pressure keeps us storm-free with a series of cold frontal passages giving way to a warming trend late next week. 1 in 3 Thanksgivings have an inch or more of snow on the ground. This will not be one of those Thanksgivings...
There wasn't much to like about Wednesday, with the gray skies, tumbling temperatures and howling winds. Other than that it was quite lovely, I guess. Winds ease up today and 40s will feel better than they should tomorrow. Next week may bring a few more relatively mild days, and if you believe NOAA's climate model for December next month may try to make up for this cold spell. We'll see...
Tuesday was murky and soggy with temperatures stuck in the 40s. A drying northwest breeze cools us off a bit today as the sun tries to punch a few holes in a stubborn cloud layer. I still don't see any big storms between now and Thanksgiving - some good news for travelers within about 500 miles of MSP.
No big storms of any flavor are brewing, just a little drizzle and light rain today as temperatures rise through the 40s - more showery rains Friday. No accumulating snow looking out 2 weeks, in fact ECMWF guidance hints at 40s, even a few 50s late next week, just in time for Thanksgiving festivities. December looks mild too...
