cyclone77 Posted July 22, 2017 Share Posted July 22, 2017 That was some wicked CG action. Large bolts were shooting right out of the updraft base as the storm moved in. Not much wind but a brief heavy downpour and the awesome lightning. Picked up a few tenths very quickly. Link to comment Share on other sites More sharing options...

HillsdaleMIWeather Posted July 22, 2017 Share Posted July 22, 2017 IWX update Update... Issued at 908 PM EDT Fri Jul 21 2017 Mesohigh bubble from early morning convection continues to slowly modify but will accelerate shortly as swrly low level jet escalates appreciably now through midnight. As a result significant low level theta-e ridge splayed out through IL/wrn IN will advect abruptly northeast. Thus evolving linear convection over wrn IL expected to grow further upscale as it comes east with several sig reports of wind gusts/damage. Additional downstream storms along the newd progressing warm front pose a near term isolated severe risk over far wrn zones currently in SV.429. Downstream watch expansion likely later this evening based on recent CAMS guidance. Link to comment Share on other sites More sharing options...

Chicago Storm Posted July 22, 2017 Author Share Posted July 22, 2017 Supercell that moved from RFD to ORD was fairly significant around here.Had small hail and only a few tree branches down here. At the time though I was in Schaumburg and took a direct hit from a microburst. Encountered 1.25" (half dollar size) hail and well as 60-70mph winds. Just down the street things were much worse, with one subdivision having damage to just about every tree. Numerous limbs/branches down, trees snapped at the truck and uprooted, trees on houses and cars and blocking roads in that area. Winds were likely upwards of 90-100mph at this location based on damage.Additionally, flooding was fairly significant as well. Most roads featured some sort of flooding, including several main roads in the area. Water was up to the windows of cars in some spots with several stalled vehicles.Up until now 8/23/07 had been the best severe storm I've experienced, but today definitely topped that.

cyclone77 Posted July 22, 2017 Share Posted July 22, 2017 Wonder when the low-level jet will start working it's magic. pretty quiet out in Iowa right now. Models would suggest we should see things explode shortly after sunset as the LLJ revs up. Link to comment Share on other sites More sharing options...
Jim Martin Posted July 22, 2017 Share Posted July 22, 2017 Text discussion from WPC... GIVEN THE LEVEL OF SHEAR AND VERY IMPRESSIVE THERMODYNAMICS...THE ENVIRONMENT OVER THE NEXT SEVERAL HOURS WILL BE HIGHLY CONDUCIVE FOR A STRONG MCS TO EVOLVE AS CONVECTIVE CLUSTERS MERGE AND CONSOLIDATE INTO A LARGER CONVECTIVE COMPLEX. THIS WILL BE AIDED BY SHORTWAVE DYNAMICS AND WARM ADVECTION AHEAD OF THIS SURFACE WAVE WHICH IS TRAVERSING A WAVY QUASI-STATIONARY FRONT. A SOUTHWEST LOW LEVEL JET IS FORECAST BY THE LATEST RAP GUIDANCE TO INCREASE TO NEAR 50 KTS BY 06Z AHEAD OF THE SURFACE WAVE..AND THIS SHOULD STRONGLY ENHANCE THE LARGER SCALE FORCING AND THERMODYNAMIC SUPPORT FOR THE CONVECTIVE COMPLEX. EXPECT RAINFALL RATES OF UP TO 3 INCHES/HR GIVEN THE DEEP COLUMN OF MOISTURE AND STRONG INSTABILITY ALONG THE FRONT. RAINFALL AMOUNTS THROUGH 06Z OF AS MUCH 4 TO 6 INCHES WILL BE POSSIBLE AND ESPECIALLY WHERE CELL-MERGERS AND SOME EPISODIC TRAINING OF CONVECTIVE CLUSTERS OCCUR. THESE AMOUNTS ARE LIKELY TO RESULT IN FLASH FLOODING...WITH SOME OF IT SIGNIFICANT GIVEN RECENT HEAVY RAINFALL AND THE URBAN CORRIDORS AREAS...INCLUDING THE CHICAGO METROPOLITAN AREA. THIS WILL LIKELY BE A LONG-LIVED MCS..AND ADDITIONAL MPDS WILL BE ISSUED ACCORDINGLY. 3 minutes ago, cyclone77 said: Wonder when the low-level jet will start working it's magic. pretty quiet out in Iowa right now.

Models would suggest we should see things explode shortly after sunset as the LLJ revs up. The disturbance that passed through western Iowa earlier this afternoon and initiated some cells out by Sioux City never did anything until it was past CR, so round one was a big zero from here westward. The HRRR has consistently developed an e-w line of convection overnight as the LLJ kicks in, but the latest runs have shifted that north and east as well, nailing ne IA through n Illinois. Once that strong outflow boundary passed through earlier today and parked over I-80, I was pretty optimistic with the setup. Link to comment Share on other sites More sharing options...

The purple triangle had a 9 in it which must mean something. Are you familiar with the spot where that viral video of the car getting lifted briefly was captured? Yeah, it was literally 1 mile from my house. We had 3 tornadoes hit yesterday here. 2 EF 1 and 1 EF2 which hit Hamburg (My town). All 3 were 4-5 miles long in their path and 500-700 feet in width. One of the largest outbreaks in WNY in history aside from 1985 where an EF4 tracked across our southern counties. http://www.spc.noaa.gov/climo/reports/170720_rpts.html Link to comment Share on other sites More sharing options...
