csnavywx Posted May 29, 2011 Share Posted May 29, 2011 Torrential downpour with lots of CGs and dense fog lol. Fun times. Looks like Tipton just got hit by some pretty strong winds according to the latest few velocity scans. You aren't kidding about the CGs, this is ridiculous. Can't remember the last time I had so many close strikes. Sounds like cannons going off every 15-20 seconds. Link to comment Share on other sites More sharing options...
Powerball Posted May 29, 2011 Share Posted May 29, 2011 DTX not only addded a severe mention to their grids, they're also only calling for T'Storms (no showers) and issued another Flood Watch. Same thing for GRR it appears. Link to comment Share on other sites More sharing options...

cyclone77 Posted May 29, 2011 Share Posted May 29, 2011 You aren't kidding about the CGs, this is ridiculous. Yeah this is a little unnerving lol. Just glad the power is staying on for now. Have over a half inch of rain already and still gushing out there. No hail at all yet though. Link to comment Share on other sites More sharing options...

Chicago Storm Posted May 29, 2011 Share Posted May 29, 2011 AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL 1105 AM CDT SUN MAY 29 2011 DISCUSSION MESOSCALE UPDATE... MCS MOVING FROM EASTERN IA INTO WESTERN IL AT 1545Z. STORMS REMAIN ELEVATED ABOVE STABLE BOUNDARY LAYER NORTH OF WARM FRONT...WHICH EXTENDS FROM ROUGHLY KUIN-KBMI-KRZL ACROSS FAR SOUTHERN WFO LOT CWA. EXPECTATION IS THAT AS WARM FRONT CONTINUES TO LIFT SLOWLY NORTH AND THAT AIR MASS DESTABILIZES WITH DIURNAL WARMING THAT STORMS WILL BECOME BASED CLOSER TO THE SURFACE...AND DAMAGING WIND THREAT WILL INCREASE ACROSS WFO LOT CWA. LATEST OBJECTIVE ANALYSIS FROM RUC INDICATES 1000-2000 J/KG MLCAPE ACROSS THE SOUTHERN/SOUTHEASTERN CWA AT THIS TIME...WITH 50-60 KT OF 0-6KM BULK SHEAR. 0-1KM SRH ALSO INCREASING IN THE VICINITY OF THE WARM FRONT WHERE BACKED LOW LEVEL FLOW WILL SUPPORT SOME TORNADO THREAT. SPC WILL BE UPGRADING DAY 1 OUTLOOK TO MODERATE RISK SHORTLY AHEAD OF CURRENT BOW. ILX 12Z SOUNDING DISPLAYS PRECIPITABLE WATER OF 1.8 INCHES...AND STORMS DEVELOPING IN WEST-EAST ORIENTATION IN WAA NORTH OF WARM FRONT ALIGNED TO PRODUCE HEAVY RAINFALL THREAT...AND ADDITIONAL STORMS EXPECTED TO BE EFFICIENT HEAVY RAIN PRODUCERS. RELATIVELY HIGH FREEZING LEVELS BETWEEN 14-15 KFT SUGGEST LARGE HAIL NOT LIKELY TO BE A BIG PROBLEM EXCEPT FROM THE DEEPEST AND MOST SUSTAINED UPDRAFTS...THOUGH ANY SUPERCELLULAR STRUCTURES COULD VERY WELL SUPPORT LARGE HAIL. SEVERE WEATHER THREAT EXPECTED TO CONTINUE THROUGH EARLY/MID AFTERNOON FROM WEST TO EAST ACROSS CWA. Link to comment Share on other sites More sharing options...

Powerball Posted May 29, 2011 Share Posted May 29, 2011 83/66 here... good instability but Capping issues are obviously going to be a big concern here. Yeah, we're into the mid 70s now with SCT stratocumulus. So obviously the inversion is still there, but it should continue to erode with time.

SEMIweather Posted May 29, 2011 Share Posted May 29, 2011 My guess is that DTX told them to hold off on the MDT risk for their CWA, as the MDT risk stops right at the western edge of the DTX CWA. I'm not seeing any signals for why it would weaken as it moves into SE Michigan but I suppose I could be missing something. Link to comment Share on other sites More sharing options...
A-L-E-K Posted May 29, 2011 Share Posted May 29, 2011 Warning with mini lead bow. Link to comment Share on other sites More sharing options...
cyclone77 Posted May 29, 2011 Share Posted May 29, 2011 Storm was sort of a snoozer here. Winds only gusted to maybe 30mph or so. Saw a report from here in town of 60mph winds, but saw nothing even close to that here. Did have a few pea size hail chunks at the tail end. The most impressive thing about the storm was the heavy rain. Almost 2" for the day now. I shot a video of it with my cell phone. Will post it once it's uploaded. Nothing spectacular, but maybe it'll give you guys off to the east a bit of a preview lol. Link to comment Share on other sites More sharing options...
kab2791 Posted May 29, 2011 Share Posted May 29, 2011 ML CAPE increasing, LIs lowering, and mid level lapse rapes steepening a bit across lower MI and NIN/NWOH. I'm wondering how L.MI will effect the northern sections of the bow. Link to comment Share on other sites More sharing options...
