Yeah, Skilling repeated the derecho word on his nine p.m. weathercast as well this evening.

Thanks Outflow for that tornado photo catch.

I hope all the booths are tied down and secure in Whiting IN for the big Pierogi festival.  Now got word the fest is being evacuated due to the svr storm warning.

I don't believe it.  I am actually in a svr t storm watch until ten central time this evening.

Funnel cloud reported on that storm north of you as I am sure you are aware Hawkeye.  Stay safe.  Watch the tor warned storm north of Newton and  Grinnell.

For those in N IL/Chicago metro, don't expect that complex out west to come rolling through with any interest.

0z DVN sounding is underwhelming to say the least...And mesoanalysis is way overdone.

 

EDIT: Disregard the above. COD having issues per usual these days, and the 0z sounding it showed me was actually from 12z. The environment is hot...carry on.

Plus I thought the LLJ was also expected to kick in this evening and overnight even though instability should wane.

33 tornado preliminary reports so far on SPC page. Must admit I did not expect this for today.

   Areas affected...Eastern IA...Northern IL...Southern WI

   Concerning...Severe potential...Watch likely 

   Valid 142242Z - 142345Z

   Probability of Watch Issuance...80 percent

   SUMMARY...Severe threat is increasing across eastern IA/northwestern
   IL into southern WI. New ww will likely be warranted soon.

   DISCUSSION...Early-day MCS has progressed across the upper Midwest
   with the leading edge now spreading across LE. Considerable
   boundary-layer disruption has been noted across WI/northern IL into
   extreme northeast IA. However, over the last few hours, partial
   clearing across eastern IA has allowed surface temperatures to warm
   into the lower 80s from east of ALO-MXO-CWI-north of C75 in
   Illinois. Further recover appears likely to near the WI/IL border
   over the next few hours. While updrafts may struggle to be truly
   surface-based where temperatures struggle to rise above 75F, there
   is increasing concern/confidence that ongoing supercells over
   central IA will progress east of ww378 into a region that is
   recovering in the wake of earlier convection. Ample shear/buoyancy
   suggest supercells will continue, along with a tornado threat.
   Additionally, LLJ is forecast to increase across southern/central WI
   this evening and this should encourage renewed convective
   development. New ww will likely be issued soo

TWC also showing some good video.

Interesting that winds are backed se to the west of the initial line of storms and surface low has deepened slightly in se CO.

   0201 PM CDT Wed Jul 14 2021

   Areas affected...southern Wisconsin...far northern Illinois

   Concerning...Severe potential...Watch possible 

   Valid 141901Z - 142100Z

   Probability of Watch Issuance...40 percent

   SUMMARY...Isolated wind damage or marginal hail will be possible
   over the next few hours, mainly focused over southern Wisconsin.

   DISCUSSION...An extensive line of storms currently stretches from
   central into southern WI, and across northwest IL where the line
   contains less trailing stratiform precipitation. Indications of
   strong to possible severe gusts are currently present with activity
   north of the IL border, and these storms may persist as the air mass
   remains favorably unstable despite high cloud cover. Around 1000
   J/kg MLCAPE exists ahead of these storms, extending south into IL.

   Some uptick in storm intensity is possible as the line moves into
   slightly more unstable air. Aside from isolated damaging gusts,
   marginal hail may occur at times. Convective trends are currently
   being monitored for watch potential.

Possible watch incoming for ne Illinois per SPC.

This is looking pretty sauced up along residual OFB in IA.

Agree per SPC meso analysis.

Yes, and after they move through we should have some increased helicity and boundaries with time to recover before the next wave comes through later this evening and night.   I also like our 70 plus dews here and to our sw.

Storm evolution does depend on MCS to our west but I like good mid level lapse rates in our area southward for later today and night.

Am currently liking prospects for training t storms and possible multiple rounds over the Chi town area later this afternoon and evening..  At 2:30 a.m. CDT this a.m. t storms extend south through Nebraska almost to the KS line.  Have a hunch the enhanced might be pulled a hair southward as well as we go through the day.  Possibly one of the few and far between interesting days we have had this year coming up for our region.

I believe Gerald Ford's motorcade was in the O'Hare area around the time that a tornado passed by on 3/12/1976.

Yes, I remember reading about that.  General t storms today.....maybe some more organized storms this weekend or just south of us.
