SEMIweather Posted May 29, 2011 Share Posted May 29, 2011 It's moving about 60 mph right now. Based on that, I would say around 6:15 although you could also have some trouble w/ WAA wing storms ahead of the line. The good news is I think Port Huron will be to the north of the worst part of the line. Link to comment Share on other sites More sharing options...

cyclone77 Posted May 29, 2011 Share Posted May 29, 2011 For anyone wondering, this squall line initially started out as a large cluster of elevated storms in southeast Nebraska/southwest Iowa between 3-4am. The numerous elevated cells quickly coalesced into a solid line as it pushed east through Iowa. Here's a radar evolution of the first few hours. http://www.rap.ucar.edu/weather/radar/displayRad.php?icao=KOAX∏=bref1&bkgr=black&endDate=20110529&endTime=10&duration=2 Link to comment Share on other sites More sharing options...

nwohweather Posted May 29, 2011 Share Posted May 29, 2011 3000 j/kg of CAPE over NW Ohio and really no CINH is going to really let this line fly through the area.

Chicago WX Posted May 29, 2011 Share Posted May 29, 2011 Stay safe bud. Thanks cyclone. Super impressive winds here...came in 3 distinct pulses in a short time...large limbs off the trees here in the neighborhood. Heard a big bang...thinking there's probably a large limb on the roof of the house. We'll see once the rain stops...which was/is a total whiteout.
