Indystorm Posted June 30, 2019 Share Posted June 30, 2019 It's certainly a weird V shaped MCS aiming for west central IN at the moment. Link to comment Share on other sites More sharing options...
King James Posted June 30, 2019 Share Posted June 30, 2019 RC, talked to the neighbor and he said he thought it was a funnel, past just north of 4000n rd near Grant ParkTo me it looked like something was on the ground. Powerline was bent at county line and 8000.Might be worth checking out Link to comment Share on other sites More sharing options...

Might be worth checking out Storms were heavily outflow dominated, but might have been a spin up. 1 Link to comment Share on other sites More sharing options...
cyclone77 Posted June 30, 2019 Share Posted June 30, 2019 That new line rolling into the tri-state area of IA/WI/IL means business. Quite a few wind damage reports have been rolling in, and now there's even a tor warning southwest of Dubuque. SPC meso page has been showing steep mid-level lapse rates feeding in from the west, and helping to very quickly rebuild any instability lost from the earlier MCS. Could get interesting down this was in the next hour or so. 1 Link to comment Share on other sites More sharing options...

Could provide additional focus. Link to comment Share on other sites More sharing options...
Indystorm Posted June 30, 2019 Share Posted June 30, 2019 And with the initial complex I thought it was interesting that Clinton and Boone counties in Indiana were svr warned because of a pronounced gust front moving from west to east across those counties without any actual storm.

janetjanet998 Posted July 1, 2019 Share Posted July 1, 2019 AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE, IL 651 PM CDT SUN JUN 30 2019 MESOSCALE DISCUSSION 555 PM CDT FLIPPING THE CALENDAR BACK EXACTLY FIVE YEARS AGO TODAY PROVIDES A GUIDE FOR HOW THE REST OF THE EVENING COULD EVOLVE, ALTHOUGH MAINLY WEST OF THE I-39 CORRIDOR RATHER THAN ACROSS THE KANKAKEE VALLEY AS IT DID FIVE YEARS AGO. THOUGH HOPEFULLY THINGS WILL NOT GET QUITE AS ACTIVE AS THAT EVENT. THE CONCERN IS THE APPROACHING CLUSTER OF SEVERE STORMS MOVING IN FROM SOUTHWEST WI. SPC MESOANALYSIS SUGGESTS AN AXIS OF LARGE INSTABILITY REMAINS IN PLACE ACROSS WESTERN IL WHILE AREAS IN THE WAKE OF TODAY'S FIRST EVENT ARE MORE WORKED OVER. WE DO NOT HOWEVER KNOW WITH CONFIDENCE HOW SHALLOW THE STABLE LAYER MIGHT BE. WE DO KNOW THERE HAS ALREADY BEEN ONE TORNADO WARNING ISSUED UPSTREAM. 0-1KM SRH VALUES ON THE MESOANALYSIS PAGE IN THE 100-200 M2/S2 RANGE ACROSS THAT AREA ARE NOT TERRIBLY HIGH, BUT LIKE FIVE YEARS AGO THESE ARE PROBABLY UNDERDONE BY QUITE A BIT BASED ON THE UNREPRESENTATIVE AND TOO SLOW STORM MOTION AROUND 15 KTS USED TO CALCULATE THESE VALUES. INSTEAD THE LEADING EDGE OF THE LINE HAS BEEN MOVING CLOSER TO 50 KTS WHICH WOULD GREATLY RAMP UP THE SRH VALUES AND SUPPORT A GREATER TORNADIC THREAT THAN MIGHT OTHERWISE BE EXPECTED. THIS OF COURSE DEPENDS ON THE STABLE SURFACE LAYER BEING SHALLOW ENOUGH TO ALLOW FOR DEVELOPMENT OF SURFACE BASED PARCELS, AND THAT REMAINS THE KEY QUESTION AT THIS TIME. A COUPLE OF AMDAR SOUNDINGS OUT OF MDW AND ORD SUGGEST THE STABLE LAYER IS AROUND 2000' DEEP AT THIS TIME, WHICH MAY BE ENOUGH TO SUPPRESS ACTIVITY AT THE SURFACE, BUT THIS IS FARTHER DOWNSTREAM OF THE APPROACHING CLUSTER AND MORE RECENTLY AFFECTED BY THE FIRST ROUND OF ACTIVITY. THE OTHER HINT OF A LINGERING SURFACE STABLE LAYER IS THE WIDESPREAD AP SEEN ON RADAR TO OUR WEST, THOUGH THIS ALSO WAS PRESENT DURING THE 2014 EVENT UP TO THE TIME THAT TORNADOES STARTED TO DEVELOP. WHAT ISN'T AS EVIDENT THIS EVENING SO FAR IS THE LOCATION OF A REMNANT OUTFLOW BOUNDARY FROM THE FIRST EVENT, WHICH WOULD SERVE TO FOCUS THE DEVELOPMENT OF TORNADIC ACTIVITY. SO FOR NOW THE TORNADO THREAT DOES NOT APPEAR TO BE HIGH RELATIVE TO A RENEWED DAMAGING WIND THREAT, BUT IF OUTFLOW FROM THE INITIAL STORMS TODAY MANAGES TO EVOLVE INTO AN EFFECTIVE WARM FRONT ACROSS NW IL THEN THINGS COULD GET MORE ACTIVE. ANOTHER KEY FACTOR THAT IS MISSING RELATIVE TO FIVE YEARS AGO IS SUFFICIENT DEEP LAYER SHEAR TO ASSIST IN ORGANIZATION AND MAINTENANCE OF THE ACTIVITY THIS EVENING. WINDS AT 500MB ARE ONLY IN THE 25-30KT RANGE. THE MOST LIKELY OUTCOME IS THAT THE STRONGEST PART OF THE SYSTEM STAYS WEST OF OUR AREA AND BEGINS TO DISSIPATE AS IT MOVES INTO THE RELATIVELY MORE STABLE DOWNSTREAM AIRMASS OVER US. BUT WE ARE JUST TRYING TO CONVEY THE FULL RANGE OF POSSIBILITIES. LENNING Link to comment Share on other sites More sharing options...

Chicago Storm Posted July 1, 2019 Share Posted July 1, 2019 Decent hit today here with the first MCS. Ended up with some smaller tree branches down in the area, estimated winds up to around 60mph.Have been without power since the storms hit...Not due to the winds, but instead lighting. A tree was struck across the way, and took down a power pole and lines, and it all caught on fire.. Link to comment Share on other sites More sharing options...

luckyweather Posted July 2, 2019 Share Posted July 2, 2019 I just drove through what I believe to be a weak tornado but radar signature doesn’t really show it. Could have been straight line wind but it it was certainly spinning around me. I was just on my commute home when in a split second I was in it. Only about a mile from home. My truck was lifting, no hail, got home and saw my plate which definitely wasn’t like that when I left the office. Went back to where it was happening and the pictured damage is there. Rural Winnebago county between Roscoe and Machesney Park. 1 Link to comment Share on other sites More sharing options...

IWXwx Posted July 15, 2019 Share Posted July 15, 2019 Mike Ryan at IND mentions the concern of a rotating storm or two tomorrow afternoon in their CWA. However, although SPC mentions it, they keep the low threat much farther south. REMAIN A TOUCH CONCERNED ABOUT A THREAT FOR A FEW CELLS TO ROTATE WITH FAVORABLE HODOGRAPH PROFILES...INCREASED SHEAR AND HELICITY VALUES...AND LCLS LIKELY TO SETTLE NEAR 1000FT...ESPECIALLY BY LATE DAY. OVERALL INSTABILITY LEVELS MAY NOT BE QUITE ENOUGH TO SUPPORT...BUT CONSIDERING THE PRESENCE OF A DEEP TROPICAL AIRMASS AND THAT MUCH OF THE FORECAST AREA IS LIKELY TO BE TO THE RIGHT OF THE WEAKENING SURFACE WAVE TRACK WHERE SHEAR MAY BRIEFLY MAXIMIZE...THIS WILL BE SOMETHING TO KEEP AN EYE ON TUESDAY.

Hoosier Posted July 15, 2019 Share Posted July 15, 2019 This is the Barry remnant. Although wind fields aloft are weakening, could have just enough shear for something. Wouldn't be shocked as it doesn't take much in these situations. Link to comment Share on other sites More sharing options...
