cyclone77 Posted July 26, 2012 Share Posted July 26, 2012 Went out to the country to shoot some distant lightning from the tops to the northwest. Very frequent lightning, but most of it was inside the clouds. Got a few okay shots, but most of them were pretty crappy. Might have to go sit outside when that outflow hits here. Still 88 out. Still getting several 50-60mph wind reports from time to time. With most of the cells behind the outflow the chances for gusts over 70mph seem limited.

turtlehurricane Posted July 26, 2012 Share Posted July 26, 2012 Things got CRAZY when the OFB came through, tropical like downpour and tons of wind. The wind got so strong it created a vortex on the street between the buildings that looked like a tornado, everyone started screaming and even I ran inside. Doubt it was the real deal though, just a gust vortice. Might've been 60 mph or higher winds in that thing tho, debris was flying through the air.

SpartyOn Posted July 26, 2012 Share Posted July 26, 2012 The Michigan storms are looking pretty lame as of right now. I'm wondering if the problem could be that the storms are oriented parallel to the 0-6km flow. If that's the case, I wonder if the SW-NE oriented line segment from White Cloud to Big Rapids can strengthen. There's still plenty of shear and instability available... There is a new bow line that has unzipped and is blasting SE. This is what was expected and will only get better throughout the night. Link to comment Share on other sites More sharing options...
aurora Posted July 26, 2012 Share Posted July 26, 2012 There is a new bow line that has unzipped and is blasting SE. This is what was expected and will only get better throughout the night. Yes. That is the line I was talking about. It is now severe warned, and I agree with you...that is going to be the main show from here on out. Link to comment Share on other sites More sharing options...
Powerball Posted July 26, 2012 Share Posted July 26, 2012 That squall line hooking down from Mount Pleasant and Grand Rapids should soon go severe and blast ESE/SE through Detroit (especially the northern suburbs) between 12AM and 2AM, probably will easily pack 65-70 MPH winds.

Gilbertfly Posted July 26, 2012 Share Posted July 26, 2012 NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL 1045 PM CDT WED JUL 25 2012 .MESOSCALE DISCUSSION... 1044 PM CDT CURRENTLY WATCHING A MULTICELLULAR LINE OF STORMS MOVING ACROSS IOWA AND SOUTHWEST WISCONSIN IN THE VICINITY OF AN APPROACHING COLD FRONT. STARTING FROM A LOW CENTERED NEAR SHEBOYGAN...THE COLD FRONT STRETCHES SOUTHWEST ACROSS IOWA THROUGH KANSAS AND INTO THE OKLAHOMA PANHANDLE. AHEAD OF THE STORMS AND THE FRONTAL ZONE LIES THE MOSTLY UNTOUCHED WARM SECTOR WHERE TEMPERATURES REMAIN IN THE MID 80S AND DEWPOINTS ARE IN THE MIDDLE TO UPPER 60S. DEEP LAYER SHEAR IS RELATIVELY SMALL AHEAD OF THE FRONT...BUT A 30-40KT LOW LEVEL JET IS SEEN IN VWP DATA AROUND THE 925-850MB LEVELS. THIS JET IS SUPPORTING BETTER SHEAR AT THE LOWER LEVELS...AS WELL AS CONSIDERABLE MOISTURE TRANSPORT TO FUEL ONGOING CONVECTION. MLCAPE VALUES OF 2000-2500 J/KG ARE BALANCED BY DCAPE VALUES OF 1500-1600...SUGGESTING THE POTENTIAL FOR CONTINUED DAMAGING WIND GUSTS AS PRESENTLY SEEN OVER IOWA. ONE QUESTION FOR THE NEXT COUPLE OF HOURS WILL BE WHETHER THE COLD POOL MANAGES TO OUTRUN THE EXISTING CONVECTION AND SHUT OFF THE MOST FAVORABLE INFLOW. WHERE THIS IS OCCURRING TO OUR WEST THE CONVECTION IS FALLING APART QUICKLY. OVERALL THE SYSTEM MOTION...THE NEW CONVECTIVE DEVELOPMENT...AND THE COLDEST CLOUD TOPS TO OUR NORTHWEST PRESENTLY SEEM TO BE SLIDING NORTHEAST ALONG THE FRONTAL ZONE. THIS MOTION IS ALSO PREDICTED BY THE DIRECTION OF THE FORWARD PROPAGATING CORFIDI VECTORS. EVEN IF THE EXISTING CONVECTION DISSIPATES BEHIND THE OUTFLOW OR SLIDES TO OUR NORTH...THE STRENGTH OF THE OUTFLOW BOUNDARIES APPEARS TO BE SUFFICIENT FOR GENERATING NEW CONVECTION DUE WEST OF OUR AREA SOUTH OF I-80. CORFIDI VECTORS FOR THIS ACTIVITY WOULD SUPPORT A MORE EASTERLY MOTION INTO THE LOCAL CWA. GIVEN THE MOISTURE TRANSPORT INTO THE AREA...HIGH PWAT VALUES...AND THE OVERALL EXTENT OF THE CONVECTION...HEAVY RAINFALL AND POSSIBLE FLOODING WILL ALSO BE A CONCERN TO BE MONITORED OVERNIGHT. ACTIVITY TO OUR WEST IS DEEMED CAPABLE OF PRODUCING 2-3 INCHES PER HOUR. HOPEFULLY WE WILL NOT GO FROM ONE OF THE DRIEST JULYS TO ONE OF THE WETTEST IN JUST ONE NIGHT LIKE WE DID ALMOST EXACTLY ONE YEAR AGO. Link to comment Share on other sites More sharing options...

cyclone77 Posted July 26, 2012 Share Posted July 26, 2012 Storms transitioned to the typical post-outflow bubbliness before reaching Cedar Rapids. We got a few decent gusts, but nothing major. 61mph at the airport south of town. A few other 60mph reports, and one 70mph estimate 1 mile south-southeast of town. Best gusts must have just missed you. The storms themselves over eastern Iowa are on the downtrend, but the outflow is still very stout as it blasts east into the boiling heat that still remains. EDIT: Iowa City gusting to 56mph from just the outflow. Pretty impressive. Link to comment Share on other sites More sharing options...
hawkeye_wx Posted July 26, 2012 Share Posted July 26, 2012 If the airport had 60 mph and a couple miles se of me in town had 70 mph, maybe I'm just underestimating wind gusts. I heard a couple gusts smack the side of the house, but when I looked out it had died down and I didn't see any sign of tree/plant debris, so I assumed it was no more than 40-50 mph. I guess I'll find out if the wind was stronger when I check the garden tomorrow. Update: There's a report of a traffic light down a couple miles north of me as well, so obviously there were some good gusts near me. Link to comment Share on other sites More sharing options...

hm8 Posted July 26, 2012 Author Share Posted July 26, 2012 MCS in N. MI seems to be having trouble becoming oriented more parallel to the mean flow, which was one of the caveats the SPC mentioned to a more widespread wind event. That being said convection is still trying to fire south along the OFB through GRR. It also looks as if showers are starting to pop up on radar further south in the state. Some volatile parameters around the metro detroit area, could get reaaalll interesting if those showers manage to become discrete cells moving into the area...

I too have been pondering that possibility all night. Only thing to impede this would be the warm lid above. Per the KDTx sounding it looks modest too.
