Stebo Posted June 25, 2013 Share Posted June 25, 2013 SW lower MI unzipping a bit A lot of empty real estate in front of that line and very strong instability with some modest shear in place too. Link to comment Share on other sites More sharing options...
Castaway Posted June 25, 2013 Share Posted June 25, 2013 That line in southwest Michigan is evolving nicely. From some reason i have a feeling some activity might start to develop in northwest Illinois. By the Iowa/Illinois border area. Northeast of Davenport. Just my personal guess.

Stebo Posted June 25, 2013 Share Posted June 25, 2013 I guess there might be a chance for SEMI as there are numerous storms going up behind the initial ones in SWMI. We'll see if they move east or southeast. Link to comment Share on other sites More sharing options...
Hoosier Posted June 25, 2013 Share Posted June 25, 2013 Quite a bit of damage in my hometown of Munster, Indiana from the storms yesterday evening. Row of 8-10 power poles were blown over just down the street from my mom. Trees/limbs knocked down in a relatively narrow path in the central/northern stretch of town. Whatever it was had to be producing winds upwards of 80 mph in that narrow zone. Hope to get some pics to post later. Link to comment Share on other sites More sharing options...

We'll see if they move east or southeast. Those are probably elevated, given that they're right under the cold pool/outflow bubble of those storms in the first row of counties.

Seems like hi-res models have consistently been showing another major mcs blowing up and charging east/southeast overnight. Agitated cu along I-80 between Des Moines and Omaha. Looks like something could pop there any time. Whatever develops there should organize into a large complex and impact the northern half of Illinois later tonight.

OHweather Posted June 25, 2013 Share Posted June 25, 2013 Was driving southeast of Cleveland when the squall line blew through around 4:30...saw winds in excess of 60MPH (probably pushing 70MPH) and saw decent sized tree limbs blowing across the road and even had a large tree fall right next to the road...was impressive.The complex over MI appears to be organizing a bit. If it can develop a cold pool it should turn more ENE towards Toledo and eventually maybe south of Cleveland as it follows the instability gradient. A 40 knot 500mb flow and over 2000 J/KG of MLCAPE should support upscale growth with that complex this evening. At least I can hope. Link to comment Share on other sites More sharing options...
Stebo Posted June 25, 2013 Share Posted June 25, 2013 Those are probably elevated, given that they're right under the cold pool/outflow bubble of those storms in the first row of counties. Elevated is fine, storms are storms in my book and you can get severe hail out of elevated storms, just a limit to wind/tornado potential. Link to comment Share on other sites More sharing options...

Also, the LLJ should be able to get it going as well as that disturbance coming in from KS. Link to comment Share on other sites More sharing options...
