Volatile Atmosphere Remains - Tornado Watch until 9 PM
May 8, 2014 — 5:19pm
Doppler Radar at 5:17 PM. There was a confirmed tornado touchdown 1 mile southwest of St. James - no reports of damage or injury. The atmosphere over southwest and south central MN remains volatile; additional sun is heating the ground and creating intense instability, couple with ample wind shear aloft. The tornado risk isn't over just yet.
Dry Slot. A surge of dry air aloft is temporarily clearing skies over southwest Minnesota, creating conditions favorable for more supercell thunderstorm into the evening hours. The Tornado Watch remains in effect from the Twin Cities on south/west up until 9 PM.
Tornado Watch until 9 PM CT. NOAA SPC has just issued a Tornado Watch, which includes the Twin Cities, Mankato, Redwood Falls and Des Moines, valid until 9 PM. It means conditions are ripe for a few tornadic, supercell thunderstorms. The immediate Minneapolis St. Paul area may be impacted by another round of strong to severe storms after 7-8 PM.

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.
We've lost 2 1/2 hours of daylight and about 4 degrees off our average high temperature; the sun now as high in the sky as it was in mid-April. No hot fronts are brewing, but today will feel like July; more 80s likely next week. The arrival of cooler air sets off a few T-storms late tonight, but Thursday there will be no doubt in your mind that the atmosphere is shifting gears. More downpours by Sunday? Well, at least the pattern is consistent...
After a less-than-optimal Saturday yesterday restored my faith in a Minnesota August. At the risk of editorializing, it was perfect. A gusty south wind tugs the mercury well into the 80s today and Tuesday; another squall line of heavy T-storms late Tuesday night into early Wednesday marks the leading edge of cooler, drier air. A few T-showers may sprout again by the weekend. I know, what a shock.
Hillary Clinton vigorously defended her family's foundation against Donald Trump's criticism on Friday and declared she's confident there will be no major further accusations involving the foundation, her emails or anything else that could undermine her chances of defeating him in November.
The GOP presidential candidate said Somali immigrants are weighing on Minnesota's safety net, and creating a terror recruitment hotbed. Critics of his remarks included Minneapolis Mayor Betsy Hodges, who said he was out of line.
It doesn't matter which publisher produces them, year after year it's the cable TV and internet providers populating the bottom of customer service lists. So delivering bad service is not just Comcast's problem, it's a whole industry's problem.
