Yeah, whenever the sirens go off (which they did tonight again) people get really freaked out and always take it seriously now. Feel bad for the kids though, they get really freaked out by any kind of storm since last year. Yet another close call this year! The good news now is that the circulation is moving through largely unpopulated areas for the most part. Hope everyone stays safe. Link to comment Share on other sites More sharing options...
janetjanet998 Posted July 18, 2016 Share Posted July 18, 2016 AREAS AFFECTED...SOUTHEAST IA...NORTHERN/CENTRAL IL...NORTHWEST IND CONCERNING...SEVERE THUNDERSTORM WATCH 393... VALID 180246Z - 180415Z THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 393 CONTINUES. SUMMARY...A SEVERE RISK SHOULD DEVELOP WEST OF WW 393 WITHIN A NEARLY WEST/EAST-ORIENTED AREA OF STORMS ACROSS SOUTHEAST IA SPREADING INTO PARTS OF NORTHERN/CENTRAL IL. MONITORING FOR AN ADDITIONAL WW ISSUANCE. DISCUSSION...ON THE WESTERN PERIPHERY OF WEAK LOW-LEVEL WAA...CONVECTION HAS GRADUALLY DEEPENED FROM KEOKUK TO DES MOINES COUNTIES IN SOUTHEAST IA. THIS ACTIVITY MAY INCREASE EAST-SOUTHEAST ACROSS PARTS OF WEST-CENTRAL IL INTO THE OVERNIGHT...TO THE WEST OF AN ONGOING SEVERE CLUSTER ACROSS NORTHEAST IL. A FAVORABLE COMBINATION OF BUOYANCY AND EFFECTIVE SHEAR PER 00Z DVN RAOB MAY SUPPORT A SUPERCELL OR TWO EMANATING OUT OF THIS CONVECTIVE ACTIVITY...ESPECIALLY AS IT CROSSES THE MS RIVER WHERE LOW-LEVEL SOUTHWESTERLIES ARE STRONGER. SEVERE WIND/HAIL SHOULD BE THE PRIMARY THREATS...BUT A TORNADO IS ALSO POSSIBLE GIVEN THE RICHLY MOIST AIR MASS CHARACTERIZED BY MIDDLE TO UPPER 70S SURFACE DEW POINTS. ACTIVITY MAY ULTIMATELY MERGE INTO A BROADER MCS FROM NORTHWEST IND WESTWARD ACROSS CENTRAL IL. Link to comment Share on other sites More sharing options...
Hoosier Posted July 18, 2016 Share Posted July 18, 2016 Watching TV now and surprised to see the coverage on the Chicago stations, especially for something that is outside the metro area.

My recollection in prior years is that they didn't cover things like this. Yeah I noticed that. I like it though, there's a lot of people who live in these small towns who don't have satellite TV, so all they get is Chicago news stations, and it's their only way to know of what's going on for some people.

cyclone77 Posted July 18, 2016 Share Posted July 18, 2016 Just had a brief downpour and a lone crash of thunder from a tiny cell that decided to pop up right over us. Picked up 0.04" in a few minutes. Link to comment Share on other sites More sharing options...

ChrisBray Posted July 18, 2016 Share Posted July 18, 2016 Hey all, I've browsed this forum for a while now but decided to go ahead and sign up to post here, since I have not seen anyone else post pictures of last night's storm that tracked from Dwight southeast towards Clifton. I left Bourbonnais about 8:45 when I realized these storms were rotating and I had a shot at a tornado. Unfortunately, my new camera is in the shop and returns tomorrow, so I had to use my old DSLR and the pictures arent that great. Here is the best one though. I would attach but I think the file size is too large and I am not sure how to embed on this forum yet. Link to comment Share on other sites More sharing options...

Intersection of E 3800N Road and N 1800 East Road in Iroquois County, looking NW 7/17/2016 about 9:39 pm. Pretty sure this was on the ground at this point. Later the storm would pass just to my north with a funnel. After that I headed east a few miles and witnessed a rope tornado that lasted a few minutes.

Natester Posted July 18, 2016 Share Posted July 18, 2016 Final rating of the Vinton tornado is very high end EF2. One mph away from EF3. VINTON, IA TORNADO RATING: EF-2 ESTIMATED PEAK WIND: 135 MPH PATH LENGTH /STATUTE/: 1.62 MILE PATH WIDTH /MAXIMUM/: 100 YARDS FATALITIES: 0 INJURIES: 5 START DATE: JULY 17, 2016 START TIME: 501 AM CDT START LOCATION: SOUTH SIDE OF VINTON / BENTON / IA START LAT/LON: 42.1531 / -92.0327 END DATE: JULY 17, 2016 END TIME: 503 AM CDT END LOCATION: SOUTHEAST SIDE VINTON / BENTON / IA END_LAT/LON: 42.1587 / -92.0025 TORNADO TRACKED ACROSS THE SOUTHERN PARTS OF VINTON, DAMAGING BUILDINGS, TREES, POWER POLES, AND OTHER STRUCTURES. THE TORNADO FIRST DAMAGED TREES, THEN HIT THE BALL FIELD WHERE IT DESTROYED FENCING, THE SCORE BOARD AND A LARGE LIGHT POLE. IT THEN TRACKED ACROSS SEVERAL MULTI-FAMILY HOUSING BUILDINGS, WHERE IT MAINLY REMOVED THE ROOF STRUCTURES. FROM THERE THE TORNADO INTENSIFED AS IT STRUCK A BRICK APARTMENT BUILDING, WHEN WAS UNROOFED AND HAD PARTS OF THE WALLS BLOWN OUT. THE TORNADO THEN FELLED A CELL PHONE TOWER AND APPARENTLY BEGAN TO WEAKEN AS IT CONTINUED ACROSS A LARGE FIELD. THE ROOFS OF ANOTHER EIGHT HOMES WERE DAMAGED AS THE TORNADO FINALLY EXITED VINTON AND CONTINUED INTO FARMLAND WHERE IT DISSIPATED. Just shows how quickly spinups can occur in a squall line.

Tim from Springfield (IL) Posted July 19, 2016 Author Share Posted July 19, 2016 FWIW we might want to extend this thread for today and perhaps tomorrow as well. Parts of S IA, NE MO, and far W IL have been upgraded to a slight risk, plus there's a MCD for most of this same area (40% watch probability). Also tomorrow's latest Day 2, even though it has a small slight for parts of the ND/MN/Canadian border area, a large marginal area extends southeastward to IL/IN (perhaps the remnants of the MN storms: http://www.spc.noaa.gov/products/outlook/day2otlk.html http://www.spc.noaa.gov/products/md/md1326.html MESOSCALE DISCUSSION 1326 NWS STORM PREDICTION CENTER NORMAN OK 1228 PM CDT TUE JUL 19 2016 AREAS AFFECTED...SOUTHERN IOWA AND NORTHERN MISSOURI CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE VALID 191728Z - 191930Z PROBABILITY OF WATCH ISSUANCE...40 PERCENT SUMMARY...A COMPLEX OF STORMS IN SOUTHERN/CENTRAL IOWA IS BEING MONITORED FOR AN INCREASING SEVERE THREAT...WHICH MAY NECESSITATE A WATCH LATER THIS AFTERNOON.

AT LEAST AN ISOLATED SEVERE THREAT WILL EXIST IN THE NEXT HOUR OR SO...AND ANY INDICATION OF A MORE SOUTHWARD FORWARD PROPAGATION INTO THE GREATER INSTABILITY MAY NECESSITATE A WW ISSUANCE.
