Chicago Storm

At least it looks good for rain and thunder tomorrow morning. If this MCS were better-timed we'd have greater severe chances, but we'll take what we can get at this point.

Timing isn't the biggest issue.

Ridge placement and environment are, both of which favor the southwestern/southern portions of the sub-forum for this upcoming stretch.

68MPH peak wind gust at MDW a short time ago, associated with a downburst.

lake enhanced outflow or something just rolled through

Corn should start tasseling soon, cicadas will be out, and the smell of sweating cornfields will soon permeate throughout. It’s July 9th and the summer keeps chugging along at a rapid pace.

real same as it ever was extended, not sure i make it 90 all summer the way things are going

deep spartman shit there.

Back-to-back days with 90's across the area. Yesterday was perfect for the 4th, with highs in the 90's, some humidity, and afternoon isolated showers/t'storms in the area.

Yesterday it topped out at 92 at ORD and MDW, and 90 at RFD. Today it topped out at 91 at ORD and 92 at MDW, with RFD 89'd.

I was, we are still down too and look to be at least for a few more days.

Chicago/O'Hare received 3.35" of rainfall on July 3rd, which broke the record precipitation total for the date of 2.06", which was set in 1982.

Forgot to mention the 90's this past Friday, June 30th. Topped out at 91 at ORD and 90 at MDW.

Passed through IL-94 a few hours ago from Dallas City, IL to Carthage, IL, 20 miles of apocalyptic destruction. Most trees were down, all homes had roof damage, many imploded grain bins, some grain bins crumpled in random fields and pushed off the road by equipment to re-open travel. Most electric poles laid down or split in half. Most corn pushed down flat. I’m not talking about a mile stretch, the entire 20 mile route was total destruction. Seems pretty certain extremely strong winds were present at the surface as the derecho pushed through that area.

DVN just issued a PNS with survey info for around there...

...SIGNIFICANT STRAIGHT-LINE WINDS ACROSS NORTHEAST MISSOURI, FAR   SOUTHEAST IOWA, AND WESTERN ILLINOIS...    

ESTIMATED PEAK WIND: 100 TO NEAR 120 MPH  

LENGTH /STATUTE/: APPROXIMATELY 150 MILES  

WIDTH /MAXIMUM/: 15 MILES   FATALITIES: 0   INJURIES: 2    

START DATE: 06/29/2023  

START TIME: 10:00 AM CDT  

CENTER START LOCATION: NEAR SOUTH GORIN / CLARK COUNTY / MO  

CENTER START LAT/LON: 40.3570 / -92.0260    

END DATE: 06/29/2023  

END TIME: 11:45 AM CDT

CENTER   END LOCATION: 5 NNE AVON IL / WARREN COUNTY / IL  

CENTER END LAT/LON: 40.6540 / -90.4480    

NOTE THAT "END LOCATION" IS NOT LIKELY WHERE SIGNIFICANT WINDS ENDED BUT WHERE THE STORMS MOVED INTO THE NWS CENTRAL ILLINOIS COUNTY WARNING AREA.    

SURVEY SUMMARY: THESE WINDS BROUGHT SIGNIFICANT DAMAGE TO DOZENS OF STRUCTURES WHILE ALSO DOWNING HUNDREDS OF TREES, IN THE TOWNS AND CITIES OF WYACONDA, MO, KAHOKA, MO, WAYLAND, MO, MONTROSE, IA, KEOKUK, IA,  FERRIS, IL, ADRIAN, IL, LA HARPE, IL, ROSEVILLE, IL, AND BUSHNELL, IL. DAMAGE AT FIRST IN NORTHEAST MISSOURI WAS IN-LINE WITH 80 TO 90 MPH WINDS, WITH APPROXIMATELY 100 LARGE TREES DOWNED ACROSS AREAS SURVEYED IN EASTERN SCOTLAND COUNTY AND MUCH OF CLARK COUNTY. THERE WAS SOME MINOR ROOF DAMAGE INCLUDING TO BUILDINGS DOWNTOWN KAHOKA. DAMAGE INCREASED IN INTENSITY NEAR MISSOURI STATE ROUTE 27. WINDS FURTHER INCREASED IN BOTH INTENSITY AND NORTH-TO-SOUTH   FOOTPRINT AS THE DERECHO APPROACHED THE MISSISSIPPI RIVER, WITH OVER A HUNDRED TREES DOWNED ALONE IN THE TOWNS OF MONTROSE AND KEOKUK, IA. MANY STRUCTURES WERE DAMAGED WITH TREES FALLING ON THEM AND SOME FROM WINDS ALONE, INCLUDING MULTIPLE MOBILE HOMES ON THE NORTH SIDE OF KEOKUK, A ROOF BLOWN OFF A HOME IN KEOKUK, AND   SEVERAL OUTBUILDINGS OR GARAGES HEAVILY DAMAGED. IN ILLINOIS, DAMAGE IN HANCOCK COUNTY WAS CONSISTENT WITH WINDS   LIKELY NEARING 120 MPH. THIS INCLUDED A LARGE COMMERCIAL RADIO TOWER FOLDED OVER, SEVERAL NEW UTILITY POLES SNAPPED AT THEIR   BASES, MULTIPLE MOBILE HOMES SEVERELY DAMAGED, SEVERAL GRAIN BINS AND OUTBUILDINGS HEAVILY DAMAGED, SEVERELY DENTED, AND/OR BLOWN FAR FROM THEIR ORIGINAL LOCATION, AND COUNTLESS LARGE TREES DOWNED. THERE WERE TWO REPORTED INJURIES IN FERRIS, ILLINOIS.

I got summertime equivalent of “mood flakes”.  Mood thunder.  Really humid feel with some dark clouds off in certain directions and rumblings far off in the distance.
Major trolling.

I'm trying to extend the dates for this thread since there's slight risk across much of the forum on 6/30 and 7/1...but not sure how to do it. Can an admin update?

You can edit the thread title by editing your first post in the thread.

That rear inflow jet -- sheesh. Looks to be outrunning the reservoir of readily available instability though. Only the southern fringe is likely to survive into the evening hours.

Given the strength of the RIJ, cold pool and advection aloft, might see some induced isentropic lift atop the "dome" and get some additional elevated thunderstorm activity to fire in its wake.

Rapid decay of the derecho as it pushed through the IND/LMK/PAH CWA's. The heavily modified air from the morning MCS in E. IL/SW. IN/W. KY killed it off fairly quickly.

Looks like renewed development is underway across SE. Illinois, with quality still TBD. A staple off high end MCS events, thought.

RIJ on the derecho being sampled at 95KT on KILX.

Speaking of the devil, random tornado warning for Bureau County, IL. Even if anything were to happen, it'd be totally rain-wrapped.

OFB accident with that one, occurring on the intersection of two OFB's.

love 2 hear it

had been modeled but was suspicious

i wouldn't count on it.

Forgot to mention the 90's this past weekend, on Saturday June 24th. Topped out at 93 at ORD, and 92 at MDW and RFD. RFD also added a 90 last Wednesday (June 21st) as well.

Hottest month of the year. Can't be possibly as worse as June, right?

ORD is down to 1 1/2SM with FU.

It would be hard to dig in to, and something LOT would have to do, but I’d imagine that might be one of the lowest FU based visibility obscuration marks ever.


.

Vis has been lowering here at ORD the past few hours, with smoke mixing down to the surface. 

Currently 3SM with FU.

Nice MCV with this complex moving through tonight, which likely helped maintain it longer than expected, given very marginal parameters.

Peak wind gusts of 50-55MPH as the main line moved through here at home a bit ago.


.

Where were we at in 2012 at this point?

THat is because it is not summer yet. Be patient grasshopper. Only five more days to go. June 21st at 10:57a.m..

could see somewhat of a pattern shake-up, as early as this weekend.
