12z Euro appears to have a strong looking MCS next Saturday evening/night developing across southern MI to E IA and dropping south across much of IL/IN/OH.

Yeah and the models had us under torrential rain and storms several days out to only be incorrect and well south this weekend, which I am fine with, though a decent thunderstorm would have been nice.  By Friday we’ll probably be under a trough and in the 60’s...

Based on the damage pics I have seen and radar data, I am confident that the tornado around Ellettsville is EF2+.

...FIRST NWS DAMAGE SURVEY FOR 06/15/2019 ...

A widespread tornado outbreak occurred the evening of June 15th
as a remnant MCV from earlier storms interacted with a warm front
in southern Indiana. This is the first PNS that covers the
surveys that were completed today, Sunday June 16th with additional
surveys to be completed tomorrow, Monday June 17th.

were destroyed as well as a loosely anchored garage
completely swept off of its foundation. The tornado
continued into rural forest before dissipating.

damage to a newly built building on Crowe Road. The owner verified
it was well built and in very good shape.  The track continued
across State Road 54 and left a wide swath of tree damage with a
resident stating over 100 acres of trees were snapped.  The

Should have clarified. Like 2 weeks ago there was early/midday rain and then late day storms which suddenly strong rotation and TDS. But yes hopefully won't be as bad.

It probably won't match the 40+ in the subforum from a couple of weeks ago, but we should end up in double digit tornadoes in Indiana. IND has teams looking at Rush, Bartholomew, Decatur, and Hancock Counties today.

EDIT: Survey team found EF-2 damage south of Rushville.

8 tornadoes so far in IN (5 in IND, 3 in ILN).  Here's an interesting tidbit... that is more tornadoes on June 15, 2019 than occurred on all June 15ths from 1950-2018 combined.

[Southern stream]

Slight risk has been added for Wednesday. Looks to me like mainly a Damaging wind threat. Haven't looked in detail at soundings this morning. The NAM last night (at that point the outlier) was showing a decent LL veering, but the rest of the column was pretty well unidirectional. Hence I think even with that solution, the main tor threat would be brief spinups along a line. Atleast in my immediate area, models are generally in good agreement, bringing a complex through mid/late evening.

[hlcater]

From a tornadoes standpoint, Thursday looks more interesting to me than Friday does(Friday seems like it's gonna be upscale city). Very subtle/low key setup in central/western IA but CAMs this evening seem to agree decently enough on 1-2 supercells in a solid environment. SPC doesn't even acknowledge this potential, which for some reason makes me more enthusiastic about it given Iowa's track record with SPC outlooks.

5% tornado probs added up to southern IL on new day 1.

[Indystorm]

Wed. system seems to be moving north a bit more than the SPC I-70 east corridor movement forecast in this morning's outlook.  Could have greater  svr implications for southern IL and IN later on today.

I'm sorry but the description of the Beech Grove tornado damage is bullsh*t.  I'm not arguing that it was only an EF1.  Heck, I called that before the first-responders ever made it to the damage.  However, "roof damage to a school and house" is ridiculous.  Multiple homes have damage, businesses west of the school lost trees and signage, the school was hit hard, the apartment complex that shares the school campus got hit and the photo that's being shared all over social media of Alro Steel is of just one of the larger businesses that received damage.  I'm looking at this mess daily so I admit, I'm a little sensitive, and I realize that the reports need to be short and factual but it reads as if they never even visited the affected area.  

[Hoosier]

I think it's an office by office thing or even just comes down to who did the survey/typed up the summary.  I have seen verbose descriptions for EF0/EF1 tornadoes but sometimes not.  I think it's more important that they were accurate (or at least as accurate as possible) with the path length, intensity, etc.

URGENT - IMMEDIATE BROADCAST REQUESTED
   Severe Thunderstorm Watch Number 400
   NWS Storm Prediction Center Norman OK
   210 PM CDT Wed Jun 19 2019

   The NWS Storm Prediction Center has issued a

   * Severe Thunderstorm Watch for portions of 
     Northeast Arkansas
     Southern Illinois
     Southwest Indiana
     Western Kentucky
     Southeast Missouri
     Northwest Tennessee

   * Effective this Wednesday afternoon and evening from 210 PM
     until 900 PM CDT.

   * Primary threats include...
     Scattered damaging wind gusts to 70 mph possible
     Isolated large hail events to 1.5 inches in diameter possible
     A tornado or two possible

   SUMMARY...Multiple clusters of storms including multicells/linear
   segments and perhaps a couple of supercells (as shear continues to
   increase through late afternoon/early evening) will pose a severe
   risk across the region.

   The severe thunderstorm watch area is approximately along and 80
   statute miles north and south of a line from 15 miles south of
   Poplar Bluff MO to 20 miles south southeast of Owensboro KY. For a
   complete depiction of the watch see the associated watch outline
   update (WOUS64 KWNS WOU0).
 

[Indystorm]

Lots of multi cell clusters in southern and central IL and IN and western KY at present.  Only a few are severe, particularly in the watch area.  Heavy rain and an occasional strong gust seem to be the greatest threats.  Dallas/Fort Worth metroplex will be where the action is today when the cap breaks.

[Jackstraw]

These storms are crawling.  Maybe 10mph.  Whole state is under a flood watch now.

Video from the Beech Grove Indiana tornado that allegedly only hit a house and did a little roof damage.  https://www.wthr.com/article/beech-grove-hs-surveillance-camera-video-shows-weekend-tornado

[Hoosier]

Whether or not it happens on the 06z outlook, I think there's a fairly decent chance that tomorrow ends up being an ENH risk around IA/MO/IL.

[Chinook]

There is a lot of model agreement on a fast-moving squall line continuing overnight, moving into northern Missouri and western Illinois in the mid-day hours, 16z to 18z. Models have varying solutions after 20z but the squall line may make it into Indiana. I am wondering if things will work out to have a lot of wind reports in the hours before noon CDT.

This is the HRRR model for 14z. Surely this would be quite unusual to have have so many 70dBz storm cores at 14z. 

[Chinook]

SPC is continuing with the 15% wind and 15% hail over a broad region of the Midwest, as well as some 2% tornado areas.  It is almost identical to the previous 17z outlook (Day 2).

I definitely wouldn't feel super comfortable about that sharp eastern edge to the slight in IL. 

[The_Doctor]

A large enhanced did end up getting issued across northern Missouri and southern/western Illinois. These severe wind-producing MCSes are my favorite storms; unfortunately for me this one will turn southeast along the instability gradient long before it gets here. This particular system is actually fairly interesting on radar, with one severe line directly behind the other. The lines are separated by less than 100 miles in spots.

[Hoosier]

ENH extended southeastward.  

[Indystorm]

This has been an interesting twin mesoscale convective system to watch today.  I wonder if a new one will form tonight over the Dakotas or MN and dive se once again and if it will take a different or similar trajectory.  By the look of the day two convective outlook from SPC I would imagine it would cover pretty much the same territory.
