I know y’all get jazzed for severe events but at this point I’ll take regular ol’ summer thunderstorms and rain once a week lol.

Once a week in the summer? Shoot, we'd be in extreme drought by August. I get what you're saying though and I agree. I'll take any kind of thunderstorm but I don't want it every day and I don't want it once every week. Somewhere in between please 😄

Way out in fantasy range but here's 2022's first modeled 600dm ridge

image.thumb.png.fc52c2d09ac97b84ebe89b9018253460.png

 

Nearly 120 degrees in Sioux Falls. Would be Cincinnati's first 100 degree day since 2012. But, again, this is at the very end of the run.

I hope so, for you. But we're in a moderate La Nina so I won't be surprised if we see a 600dm ridge at some point this summer.

Well it would dry us out in a hurry anyways! 

That would be a roll out of bed, make coffee, watch tv, take a nap, make more coffee, watch more tv and never get out of my pajamas kind of day.  Screw that lol.

A hybrid 2012 isn't very fun, thank you very much. Mostly dry but with more humidity. We get another ridge like that, then upper Midwest steals the show(again) for severe weather potential. That ring of fire pattern helped Lower Great Lakes regain some of that soil moisture, sure. But we've had some near-record breaking dew dew points as a result.

lightning directly hit this radar and broke it. before that, some 92mph wind detected by base velocity

 Day 1 Convective Outlook  
   NWS Storm Prediction Center Norman OK
   1130 AM CDT Sat Jul 09 2022

   Valid 091630Z - 101200Z

   ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS THIS EVENING
   INTO TONIGHT FROM CENTRAL MT INTO WESTERN ND...

   ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS THIS
   AFTERNOON/EVENING FROM CENTRAL AL INTO CENTRAL/NORTHERN MS...

   ...SUMMARY...
   Scattered severe thunderstorms are expected later this afternoon
   through tonight across Montana into North Dakota, with damaging
   winds and large hail likely. Occasional damaging gusts will also be
   possible this afternoon/evening across parts of Alabama and
   Mississippi.

   ...MT/ND late this afternoon through tonight...
   Similar to the previous two days, midlevel shortwave troughs will
   move around the northwest periphery of the Four Corners midlevel
   high, from the interior Northwest across MT to ND through tonight. 
   Despite overnight convection, boundary-layer dewpoints remain in the
   mid 50s to near the higher terrain in west/southwest MT (somewhat
   higher dewpoints across eastern MT).  Steep midlevel lapse rates
   will again be replenished from the southwest, which in concert with
   daytime heating, will result in MLCAPE near 1500 J/kg this
   afternoon/evening.  Deep-layer vertical shear will be fairly strong,
   with long hodographs and effective bulk shear in excess of 45 kt.

   Much like yesterday, scattered thunderstorm development is expected
   near or just after 21z, over and immediately northeast of the
   mountains in southwest MT.  Some of these storms could develop
   supercell structures with an attendant threat for large hail of 2+
   inches in diameter.  Later this evening, some upscale growth into
   one or more clusters is expected, with an increase in the threat for
   damaging winds of 75+ mph.  Embedded supercells will remain
   possible, especially on the southern flank of the convection, as the
   cluster(s) move eastward across ND tonight.

   ...Southeast into TX this afternoon/evening...
   Downstream from a midlevel high centered near the Four Corners, a
   broad zone of cyclonic flow aloft persists from the MS Valley to the
   Mid-Atlantic/Carolinas.  Embedded perturbations within this cyclonic
   flow, enhanced by prior convection, will continue to move
   east-southeastward over the Southeast, as a surface cold front
   drifts slowly southward across VA/KY/TN/AR and north TX.  Morning
   clouds/convection across north GA/northeast AL will produce weak
   outflow and differential heating zones that will drive afternoon
   thunderstorm development farther south and west from central AL into
   the Mid-South along the cold front.  Hot afternoon temperatures of
   95-100 F and boundary-layer dewpoints in the mid 70s will boost
   MLCAPE to 3000 J/kg or greater, with thunderstorm development
   expected by early-mid afternoon.  Convection will likely grow
   upscale into a couple of clusters/lines and spread southward through
   late afternoon/evening.  Though flow aloft will be weak, the large
   buoyancy and DCAPE near 1000 J/kg will support occasional damaging
   downbursts. 

   Farther east, the morning convection across GA may persist into the
   afternoon while spreading southeastward, and additional storms are
   expected to form along the differential heating zone across the
   Piedmont, and along the cold front moving southward into NC. 
   Vertical shear will remain rather weak (slightly stronger along the
   front in NC), and thermodynamic profiles from GA into the Carolinas
   will not be quite as supportive of downbursts compared to MS/AL. 
   Thus, isolated strong/damaging outflow winds will be possible with
   multicell clusters this afternoon from GA into NC.

   Strong surface heating (afternoon temperatures well above 100 F) and
   inverted-v profiles along the slow-moving front across north TX will
   support the threat for high-based thunderstorms with isolated severe
   outflow winds for a few hours later this afternoon/evening.

Kinda funny to have an enhanced risk this large, covering half of one state and, like, a third of another... yet only 330k people are under it.

Dayton is 55 square miles, population of 137k. 
Enhanced risk is almost 1200x the size of Dayton, but population is 2.44x more

I'm sure the numbers are even funnier if you use NYC or Chicago or LA but meh.

Seeing that they say destructive winds possible, have to wonder if they go with a PDS severe thunderstorm watch.

   Areas affected...central and eastern Montana

   Concerning...Severe Thunderstorm Watch 452...

   Valid 100012Z - 100315Z

   The severe weather threat for Severe Thunderstorm Watch 452
   continues.

   SUMMARY...A substantial severe threat will evolve this evening
   across central and eastern Montana, with destructive winds and hail
   expected. A new watch is likely east of WW 452.

   DISCUSSION...Storms continue to increase in intensity and coverage
   over central MT, with several cells now exhibiting a
   rightward/eastward motion as of 00Z. As height falls with the
   shortwave trough continue this evening, low-level easterlies will
   increase, with 850 mb winds providing moist storm relative inflow.
   As this occurs, an MCS may eventually materialize, with a threat of
   wind-driven hail and damaging winds. Individual cells may also
   produce very large hail in excess of 2.00" diameter. The very steep
   lapse rates aloft combined with strong shear should maintain the
   severe threat beyond 06Z despite small boundary-layer inhibition
   from cooling, eventually entering ND later tonight.

With the way the past 8 months have gone, I bet this is gonna be another 20+ significant wind day

FWIW, 18z NAM has a PDS TOR sounding in east-central MN tomorrow

Notice the 80 knot upper level jet. That causes problems in the summer.

Sounding in south-central MN

 URGENT - IMMEDIATE BROADCAST REQUESTED
   Severe Thunderstorm Watch Number 453
   NWS Storm Prediction Center Norman OK
   730 PM MDT Sat Jul 9 2022

   The NWS Storm Prediction Center has issued a

   * Severe Thunderstorm Watch for portions of 
     Central and Eastern Montana
     Western North Dakota

   * Effective this Saturday night and Sunday morning from 730 PM
     until 400 AM MDT.

   * Primary threats include...
     Widespread damaging winds and isolated significant gusts to 80
       mph likely
     Scattered large hail and isolated very large hail events to 2.5
       inches in diameter likely
     A tornado or two possible

   SUMMARY...A line of intense thunderstorms over central Montana will
   track eastward across the watch area this evening and tonight.  Much
   like last night, swaths of damaging winds and hail are expected.

   The severe thunderstorm watch area is approximately along and 85
   statute miles north and south of a line from 85 miles west southwest
   of Glasgow MT to 5 miles north of Garrison ND. For a complete
   depiction of the watch see the associated watch outline update
   (WOUS64 KWNS WOU3).

   PRECAUTIONARY/PREPAREDNESS ACTIONS...

   REMEMBER...A Severe Thunderstorm Watch means conditions are
   favorable for severe thunderstorms in and close to the watch area.
   Persons in these areas should be on the lookout for threatening
   weather conditions and listen for later statements and possible
   warnings. Severe thunderstorms can and occasionally do produce
   tornadoes.

   &&

   OTHER WATCH INFORMATION...CONTINUE...WW 451...WW 452...

   AVIATION...A few severe thunderstorms with hail surface and aloft to
   2.5 inches. Extreme turbulence and surface wind gusts to 70 knots. A
   few cumulonimbi with maximum tops to 500. Mean storm motion vector
   26035.
