Barely got wind 🙃

Power just came back on as I typed that. Was out for about 40 mins.
 

Man, I always complained about how easy power got knocked out back when I lived in West Chester and Dayton but this doesn’t even come close to competing

Edit: and now it’s back out

@ClicheVortex2014, did you take photos or videos of this squall line? I would love to hear the rain and/or lightning!

It was dark so there’s nothing to see… especially once the power went out. Blowing rain was getting the garage wet and we still have stuff in it

For such an obscure/unexciting setup, sure has been a hell of a day.

An unexpected local tornado outbreak in Wisconsin

A couple discrete tornadic supercells in E KY

3 well-spread out 2" hail reports across the South

Very well-defined LEWP across the mid-south

And now there's another tornadic supercell in N MS.

Impressive trough with an impressive jet streak... but the significant hail reports are in relatively weak flow. Never really expected an early fall event to be forced by a trough diving southeast. Much less forcing severe weather on such a large scale. I hope this isn't a sign of things to come.

Though, to be fair, if you just isolate the jet streak without looking at the bigger picture, a jet streak punching into the Lower GL is a pretty classic fall outbreak signature. We're lucky the low is all the way up in Canada and moisture was weak across the OV. We can likely credit that to the trough diving southeast rather than from the west or southwest.

   Mesoscale Discussion 1873
   NWS Storm Prediction Center Norman OK
   0252 PM CDT Sat Oct 15 2022

   Areas affected...Eastern OK into central AR

   Concerning...Severe potential...Watch possible 

   Valid 151952Z - 152145Z

   Probability of Watch Issuance...60 percent

   SUMMARY...Thunderstorm development is possible by late this
   afternoon, and will become more likely by early evening. The
   strongest storms will be capable of producing hail and damaging wind
   gusts, and watch issuance is possible.

   DISCUSSION...Cumulus is increasing this afternoon from eastern OK
   into central AR, in an area of strong surface heating south of a
   diffuse stationary front, and along the northern periphery of deeper
   low-level moisture. The timing and coverage of storm development
   late this afternoon is somewhat uncertain, due to weak low-level
   convergence and residual capping. However, isolated development
   cannot be ruled out late this afternoon, with greater coverage
   expected by early evening near and north of the boundary as
   low-level warm advection increases with time. 

   Modest northwesterly midlevel flow is supporting effective shear of
   30-40 kt across the region, which will support organized storm
   development within the moderately unstable (MLCAPE of 1500-2000
   J/kg) environment. Initial development will likely be discrete, and
   a couple of supercells will be possible with an attendant large hail
   risk. Relatively large temperature/dewpoint spreads and weak
   low-level flow/shear across the warm sector will result in a
   tendency for storms to become outflow dominant, with isolated
   strong/damaging gusts possible. 

   In order to address these threats, watch issuance is possible once
   robust storm initiation appears imminent across the region.

Watch up for Eastern Oklahoma and Central Oklahoma, basically along I-40 from Okemah, OK to Memphis, TN

   Areas affected...Western and Central Oklahoma

   Concerning...Severe potential...Watch possible 

   Valid 152201Z - 160000Z

   Probability of Watch Issuance...60 percent

   SUMMARY...Scattered convection, some severe, is expected to increase
   across western and central Oklahoma this evening. Damaging wind and
   hail are the primary threats.

   DISCUSSION...Very weak disturbance appears to be ejecting east
   across the TX Panhandle late this afternoon. This feature is
   expected to aid convective development along a front draped from
   south of TUL-north of OKC-south of GAG over the next several hours.
   Convective temperatures have been breached along this wind shift and
   latest satellite imagery depicts deepening cumulus, a few of which
   may soon glaciate. While low-level flow is not particularly strong,
   this front will serve as the focus for robust thunderstorms that are
   expected to grow upscale into one or more clusters as they propagate
   southeast. Forecast soundings suggest wind may be the greatest risk,
   though hail is also possible, especially with early supercell
   structures.
