Tornado Watch. Valid until 8 pm Saturday evening conditions aloft are ripe for more supercell T-storms, greatest risk south/west of the MN River, but a few strong/severe storms may reach the metro area this evening. You should be ok for outdoor activities through 5 pm, after that all bets are off. Stay alert - stay tuned for more updates.

Tornadic "Mesocyclone". Also known as a "supercell", these long-lasting (rotating) thunderstorms show up on Doppler - the big tornadoes are (relatively) easy to spot - rarely forming in a line of storms, but rather lone, individual cells out ahead of a line of storms. These are the ones you have to watch. The supercell that formed near Montevideo tracked to the east southeast, sparking 3-4" diameter hail, and eventually all that spin lead to "tornadogenesis" as the supercell reached Fairfax/Klossner/Searle.

Not Again. Here we go again - the wind/moisture profile is ripe for a few more rotating "supercell" T-storms, especially over far southwestern MN later today and early tonight. I expect another round of watches/warnings - best chance of isolated reports of hail, violent straight-line winds, flash flooding, even a stray tornado: between 4 and 8 pm.

* At least 6 separate tornadoes in Minnesota Friday. Total for the season (so far) may be as many as 30. That is how many tornadoes we normally receive during an entire summer season.
* We aren't out of the woods just yet: slight severe storm risk again later today and this evening.
* Next week: one of the nicest of summer? Lower humidity, bright sun (and dry!) from Monday through Friday.
* Tropical depression east of the Yucatan forecast to strengthen into a hurricane over the Gulf of Mexico - the GFDL model brings "Hurricane Alex" into Louisiana next Wednesday with sustained winds close to 100 mph. The outlook is very much up in the air - you can only imagine how oil-plagued residents living on the Gulf of Mexico must feel right now.


Is it safe to go outside yet? Good grief, I feel like writing a (fictional?) account of a weather-traumatized guy afraid to leave his basement - perpetually hiding under the stairs, trembling, cowering - terrified to wander up the steps. I have met hundreds of Minnesotans who have what I can only describe as "weather-phobia", some event, a storm, tornado, flood, close lightning strike, something put the fear of God into them and it impacts how they live their lives. They fixate on the forecast, paralyzed by fear of the unknown - a storm within 50 miles triggers severe anxiety, sweaty palms, heart palpitations, pacing back and forth - unable to think (or move forward) because of the mere threat of a thunderstorm. Kids (and adults) who witness severe weather can suffer some of the same symptoms as PTSD patients, post traumatic stress disorders that trigger a physiological reaction.
Speaking from experience, living through a tropical storm at the ripe age of 14, having our home damaged by severe flooding, watching a guy drown in the stream behind our house, seeing dozens of 200-year old covered bridges washed downstream, had a powerful impact on me. Living through Tropical Storm Agnes sealed my fate - I wanted to understand what had happened to me, to my family and town, and I started studying hurricanes, then tornadoes, severe storms - ultimately leading to a career in meteorology. Think about it, nobody in their right mind wakes up and says, "hey - I want to be a weatherman!" Most TV meteorologists have a similar story, some wild & crazy weather event in their youth set them on a permanent career track.
I digress (sorry). You endured/survived another wild day, 8 days after the biggest tornado outbreak in 18 years (20 in one day last Thursday) we had another outbreak of tornadoes, straight-line winds and damaging hail. Golf ball to baseball size hail was reported, even in the immediate metro area, along with flash flooding - coming (conveniently) right around the evening rush, as people were trying to get home, head up to their cabins. Bad timing.
I don't think we'll get a clear understanding of how many tornadoes there were until National Weather Service teams have a chance to (literally) get out into the field and assess the damage from yesterday's storms. I counted 6 separate tornadoes, with the most intense (seemingly) west of Mankato, around Searles and Kossner, where a "rain-wrapped" tornado was reported. This is one of the most dangerous kinds of tornadoes, because (from a distance) it doesn't resemble a classic tornado funnel - it looks like a heavy shower, or a thunderhead that has lowered all the way down to the ground. Only strong counterclockwise rotation would be a tip-off that there is a tornado inside that curtain of rain. Rain-wrapped tornadoes are relatively rare - only Doppler radar can penetrate the outer coating of rain and detect the severe rotation of the parent thunderhead above (in almost every case the actual tornado itself is too small to show up on Doppler - the rotation visible on Doppler, the resulting "couplet" is of the attached T-storm, not the twister itself).
I've included a NWS damage report below.


It has been a rough June, between the tornadoes, monster-hailstones and gloomy, soggy weekends. We're due for a break, and it's almost here. A transfusion of drier, cooler Canadian air should treat us to 4-5 dry, sunny, comfortable days/row next week. July 4th weekend weather?
How 'bout those Twins?
