outflow Posted June 9, 2011 Share Posted June 9, 2011 sebewaing is a mess, i bet at least 25% of the trees in town came down. Most roads closed/blocked. The airport is pretty much destoryed, hangers torn apart, planes flipped and wrecked. Barns destroyed around and outside of town. Seen a enclosed snowmoblie trailer flipped over in a field about a 1/2 mile from the nearest farm. Worst storm locally in the past 5 years. Had some gusts to near 60mph at my house, a few big limbs down in my town, but nothing compared to 20 miles to the west. http://www.wnem.com/index.html pics and video from the local news stations.

Short Fuse Composite Maps: http://www.crh.noaa....op/?n=shortfuse I made a little map on my website that shows the domains of the WFO's that have SFC maps, and linked them on that same map: http://www.lblaforce.com/wx (have to scroll down a little bit) Oh yeah, some of the WFO's SFC maps have been messed up-like not showing certain parameters, or the completely wrong date.

tornadotony Posted June 10, 2011 Share Posted June 10, 2011 Thought I'd make this cool little schematic of a supercell on radar. As this storm passed just N of KICT radar, the radar caught a good glimpse of several of the features. In the schematic, you can see FFD divergence, which takes place in the core of the thunderstorm, FFD convergence at the leading flank, RFD convergence where the RFD rushes outward, inflow into the mesocyclone, and the mesocyclonic circulation itself. Pretty neat. Link to comment Share on other sites More sharing options...

Siberian Express Posted June 10, 2011 Share Posted June 10, 2011 enhanced tornado threat, LLJ kicking in........................ MESOSCALE DISCUSSION 1163 NWS STORM PREDICTION CENTER NORMAN OK 0743 PM CDT THU JUN 09 2011 AREAS AFFECTED...SE NEB..NE KS...NRN MO...WRN IL CONCERNING...TORNADO WATCH 453...454...455... VALID 100043Z - 100215Z THE SEVERE WEATHER THREAT FOR TORNADO WATCH 453...454...455...CONTINUES. THE SEVERE THREAT WILL CONTINUE ACROSS WEATHER WATCHES 453...454 AND 455 OVER THE NEXT FEW HOURS. THE MORE INTENSE CELLS WILL HAVE A THREAT FOR LARGE HAIL AND WIND DAMAGE. A TORNADO THREAT WILL ALSO EXIST ESPECIALLY IN ERN KS...FAR SE NEB AND NRN MO WHERE THE TORNADO THREAT IS EXPECTED TO INCREASE EARLY THIS EVENING. A CLUSTER OF INTENSE SUPERCELLS IS ONGOING IN ECNTRL KS ALONG AN AXIS OF STRONG INSTABILITY WITH MLCAPE VALUES IN THE 2500 TO 3500 J/KG RANGE. THE ACTIVITY IS LOCATED JUST AHEAD OF A COLD FRONT VERY CLOSE TO A LOW-LEVEL JET MAX EVIDENT ON MESOANALYSIS. AS THE LOW-LEVEL JET STRENGTHENS EARLY THIS EVENING...THE TORNADO THREAT SHOULD INCREASE AS SUPERCELLS INITIATE AND EXPAND IN COVERAGE. WSR-88D VWPS IN ERN KS...SE NEB AND NW MO SHOW 0-3 KM STORM RELATIVE HELICITIES IN THE 200 TO 400 M2/S2 RANGE SUGGESTING AN ISOLATED STRONG TORNADO THREAT MAY DEVELOP OVER THE NEXT FEW HOURS AS LOW-LEVEL SHEAR PROFILES BECOME MORE FAVORABLE DUE TO THE LOW-LEVEL JET. IN ADDITION...LARGE HAIL GREATER THAN 2 INCHES IN DIAMETER MAY OCCUR WITH THE MORE DOMINANT SUPERCELLS DUE TO THE VERY STEEP LAPSE RATES AND STRONG INSTABILITY IN PLACE. THE WIND DAMAGE THREAT MAY ALSO INCREASE ESPECIALLY IF STORMS CAN CONGEAL INTO A LINE AS IS SUGGESTED BY SEVERAL SHORT-TERM MODELS. FURTHER TO THE EAST ACROSS WW 455...A CLUSTER OF SEVERE STORMS IS ONGOING JUST UPSTREAM OF THE WATCH IN NRN MO ALONG THE NRN EDGE OF MODERATE INSTABILITY. THIS CLUSTER SHOULD CONTINUE HAVE A POTENTIAL FOR LARGE HAIL AND WIND DAMAGE MOVING INTO THE WRN PART OF WW 455 OVER THE NEXT HOUR ENABLING THE WATCH TO CONTINUE THROUGH EXPIRATION.. ..BROYLES.. 06/10/2011 Link to comment Share on other sites More sharing options...

Jonbo Posted June 10, 2011 Share Posted June 10, 2011 Had a decent hailstorm move through. Somewhat unexpected since it seemed to intensify right over Ankeny. Got a few decent pictures and a video. Mostly an inch for me. Saw one hailstone closer to 1.25". Lasted a good 3-4 minutes I'd guess. Link to comment Share on other sites More sharing options...

cyclone77 Posted June 10, 2011 Share Posted June 10, 2011 Cyclone in Erie is getting nailed right now, possibly with a bit of hail and definitely strong wind. Had 40-45mph winds and very heavy rain. Some pretty strong winds just south of town. Had to dodge tree limbs laying over the road on the way to work early this morning. Link to comment Share on other sites More sharing options...
