Had some flash flooding here earlier. Dips in the roads got really bad, almost impassable. I don’t have pics or videos of the worst of it but I did get some videos of some urban flooding

ILN is doing a survey of the Kettering area of damage from a possible tornado.

[ClicheVortex2014]

Gotta say... I'm a big fan of central time. It's literally being in Eastern standard time during the warm season. Gonna make winter even better because I'm getting the 0z suite 2 hours earlier than EDT.

PUBLIC INFORMATION STATEMENT
NATIONAL WEATHER SERVICE WILMINGTON OH
322 PM EDT MON AUG 22 2022

...RESULTS FROM MONTGOMERY AND GREENE COUNTY DAMAGE SURVEY...

IN COORDINATION WITH THE MONTGOMERY AND GREENE COUNTY EMERGENCY
MANAGEMENT AGENCIES, THE NATIONAL WEATHER SERVICE OFFICE IN 
WILMINGTON OH CONDUCTED A STORM SURVEY TODAY FROM THE OAKWOOD
AREA, THROUGH KETTERING AND INTO THE SOUTHWEST PORTIONS OF
BEAVERCREEK, OHIO. THE SURVEY IS IN RELATION TO THE SEVERE 
THUNDERSTORMS THAT MOVED THROUGH THE AREA ON AUGUST 21, 2022. 

AN APPROXIMATELY 4.5 MILE SWATH OF INTERMITTENT WIND DAMAGE,
MAINLY TO TREES, WAS SURVEYED. IN THE OAKWOOD AREA, DAMAGE WAS
BROAD AND SPORADIC IN NATURE, CENTERED ON FORRER BOULEVARD BUT
EXTENDING SEVERAL BLOCKS NORTH AND SOUTH OF THE BOULEVARD, OVER A
HALF MILE WIDE AT TIMES. TREE DAMAGE IN THIS AREA WAS MOSTLY 
COMPRISED OF SMALL AND LARGE LIMB BREAKS, BUT A FEW UPROOTED TREES
WERE NOTED. TREE DAMAGE WAS NOT DETERMINED TO BE CONVERGENT OR TO
HAVE A PARTICULARLY STRONG CROSS-PATH COMPONENT WHEN TAKEN IN 
SUM, AND POINTED MORE TO BEING NON-TORNADIC IN NATURE.

GAPS OF MORE CONSISTENT WIND DAMAGE WERE EVIDENT BEFORE ANOTHER
AREA OF MORE CONCENTRATED WIND DAMAGE IN KETTERING ALONG ARAGON
AVENUE AND VALE DRIVE, INCLUDING AN APARTMENT COMPLEX WHICH HAD
SEVERAL TREES HEAVILY DAMAGED. LIKE WITH THE OAKWOOD AREA DAMAGE,
LITTLE EVIDENCE OF A CONCENTRATED TORNADIC CIRCULATION EXISTED IN
THE TREE DAMAGE, WHICH AGAIN CONSISTED OF LARGE BROKEN LIMBS AND 
AN UPROOT OR TWO.

ANOTHER RATHER SIZABLE GAP OF CONCENTRATED WIND DAMAGE WAS NOTED 
BEFORE A FEW INSTANCES OF WIND DAMAGE IN GREENE COUNTY IN 
SOUTHWESTERN BEAVERCREEK. HERE, A FEW TREES HAD BROKEN LIMBS, AND 
A HOUSE HAD SIDING REMOVED FROM THE TOP OF THE HOME AND THROWN 
DOWNWIND. 

THE RESULTS OF THE DAMAGE SURVEY SUGGEST THIS DAMAGE WAS LIKELY TO
BE NON-TORNADIC IN NATURE, WITH MAXIMUM WIND SPEEDS BETWEEN 65 AND
70 MPH. 

THE NATIONAL WEATHER SERVICE WOULD LIKE TO THANK THE MONTGOMERY
AND GREENE COUNTY EMERGENCY MANAGEMENT AGENCIES FOR THEIR SUPPORT
OF THIS SURVEY.  

THE STORM SURVEY INFORMATION WILL ALSO BE AVAILABLE ON OUR 
WEBSITE AT HTTP://WWW.WEATHER.GOV/ILN

Kinda wild because, before I moved, I was working for Kettering Parks & Rec before I moved, and this damaging wind report was just northeast of where I got off the highway. I would've been salty as hell if there was a tornado there so soon after I moved.

This is a historical storm that I was looking up a few days ago. On 2/5/2008, there was a 122-mile long tornado with maximum damage of EF4, in Arkansas. This was one of the most active tornado days in the  wintertime. Here is the archived radar that I generated, showing the TVS data, a detected 150 knot delta-V

That was an insane outbreak. Unrivaled in intensity for winter outbreaks until 12/10/21. Even then, it could be said that Super Tuesday 2008 was more widespread/intense on a larger scale. But 12/10 really shook things up with respect to winter outbreaks.

Forgot to mention that yesterday was the 6 year anniversary of the tornado outbreak that occurred in the Lower Great Lakes region. 42 confirmed tornadoes stretching from north central Indiana to NW Ohio.

That was a lucky day for me. Called off work that day when they decide to go Moderate. Morning started off with some minor convective debris but soon cleared around noon. Got in a car with a couple of local storm chasers and the rest was history. We were chasing just west of Van Wert when my team and I saw a funnel advancing NW of the city.  Touched down and immediately ran into some barns in that simcity. Didnt know that that would become my 2nd EF2+ of my chasing career. Picture is from when it was north of the city about to cycle.

Made it back to Lucas in time to catch another cell that briefly produced just North of Whitehouse. Pretty sure that report is included in the storm report. But that was very brief and lasted only a few minutes.

Worst severe outbreak in this area since June 2010. Something tells me this area is overdue for something of this nature to happen again soon.

I remember that one being last minute-y. There's a youtube video from livestorms media showing a massive wedge from one of those cells.

Second round of very heavy rain today. Gotta say, heavy rain hits different in Tennessee. Rain drops have been much larger and that is contributing to less favorable driving conditions than I became accustomed to in Ohio. I had a high tolerance for driving in the rain and I enjoyed it, but this has been borderline unbearable.

First gif is current. Second is earlier. The picture is after the earlier storm.

Florida is on line 2 for you

About to have two slight risk days in a row... gonna be 3 tomorrow. 🤯

[ClicheVortex2014]

Looking like a possibly active day tomorrow. Maybe initial/brief supercells before going linear.

 

Pretty decent environment ahead of the initial possible supercells

Significant tornado parameters could some decent values of 1 to 3 in Minnesota with several severe storms happening. The GFS has some terrific values of SRH to 400 m2/s2.

Yea the more south you go the bigger everything is. I have noticed even in Ohio we've been getting bigger raindrops than in the past. Hmm.

The ones I had a few weeks ago were also massive!

I smell decent tornado potential tonight in central/northern Minnesota tonight so i'm climbing out of my hibernation hole to post soundings 🙂. Appears to be a 2-3 hour window where storms could be discrete/semi-discrete before eventually going linear, looks like the northern section could stay cellular, something to watch.

I mean really what more could you ask for, slightly higher sfc-3km lapse rates maybe, and a bit more sfc shear, that's all nitpicking though. Definitely an evening to stay weather aware if you live in north-central Minnesota.

 

[StormfanaticInd]

Tomorrow is getting more interesting. New outlook 

[ElectricStorm]

Little storm just blew up right on top of me 😀

Nice little marginal risk too

[ClicheVortex2014]

Saw a couple tweets at 5pm, with 2-3 hours of sunlight left, that S MN is gonna bust. Oops.

   Areas affected...central/southern Minnesota

   Concerning...Tornado Watch 526...

   Valid 282320Z - 290115Z

   CORRECTED CONCERNING LINE

   The severe weather threat for Tornado Watch 526 continues.

   SUMMARY...Discrete supercell development appears increasingly
   probable into the 7-9 PM time frame, before storms consolidate into
   an organizing cluster.  Large hail appears the primary initial
   severe hazard, though potential for a couple of tornadoes could
   increase before the risk for damaging wind gusts becomes more
   prominent later this evening.

   DISCUSSION...Deepening convection is evident along the surface
   trough axis into areas near/east of the South Dakota/Minnesota
   border, perhaps most notably near a weak surface low to the
   west-southwest of Alexandria, MN.  This low coincides with the
   intersection of the surface trough and a weak warm front which has
   developed, aided by differential surface heating beneath the nose of
   a plume of capping elevated mixed-layer air, east-south of the low
   toward the La Crosse, WI vicinity.

   The leading edge of cooling around the 700 mb level is in the
   process of overspreading the western Minnesota/Dakotas border
   vicinity and seems likely to support more rapid thunderstorm
   development to the south of the main ongoing initial cluster near
   Bemidji, MN within the next couple of hours.  Aided by steep
   lower/mid tropospheric lapse rates, low-level moisture is
   contributing to mixed-layer CAPE in excess of 2000 J/kg east of the
   surface trough axis and along/southwest of the warm frontal zone. 
   In the presence of strengthening deep-layer shear beneath an
   approaching 50+ kt jet in the 500-300 mb layer, the environment is
   becoming increasingly conducive to organized severe storm
   development

   Strongest storms into the 00-02Z time frame probably will become
   focused along and to the cool side of the warm frontal zone (roughly
   near/north of the Interstate 94 corridor), where discrete supercells
   are possible initially before forcing for ascent associated with
   warm advection contributes to an upscale growing thunderstorm
   cluster.  With low-level hodographs still generally weak, large hail
   may be the primary initial severe hazard.  However, modest
   strengthening of flow (to around 30+ kt) in the 850-700 mb layer by
   early evening may enlarge clockwise curved low-level hodographs
   enough to contribute to a risk for a tornado or two, particularly
   along the warm frontal zone, before damaging surface gusts become
   the more prominent hazard later this evening.

These area some impressive late-August severe weather parameters, in the area of the current tornado watch.
