IWXwx Posted May 4, 2012 Share Posted May 4, 2012 Updated "survey" information from Tuesday's sup. May 1 Tornado (Updated) Two tornadoes have been confirmed from the May 1st storms. Tornado 1: Location: Fountain County, near Yeddo Rating: EF-0 Time: 6:57 PM EDT. Width: 50 yards Path Length: 0.1 mile The tornado touched down briefly in a field. Tornado 2: Location:Montgomery County, near New Ross (along County Road 500S between CR625E and CR700E). Rating: EF-1, winds of 100 mph to 110 mph Time:7:36-7:37 PM EDT. Width: 150 yards Path Length: about 0.5 mile The tornado was rated based on eyewitness Skywarn storm spotters' reports, pictures and videos of the tornado and damage, and from Indianapolis TV stations' damage pictures. The damage rating was based on a destroyed barn, and damaged nearby homes, trees and power poles. Investigation shows that the report of a tornado near Columbus was not valid. Investigation of the tornado report near Cory southeast of Terre Haute is still ongoing. Link to comment Share on other sites More sharing options...

Hoosier Posted May 4, 2012 Share Posted May 4, 2012 Still some differences with how the models are handling the event later this weekend. Some nice turning with height on the forecast soundings but flow is pretty weak overall. Link to comment Share on other sites More sharing options...
SchaumburgStormer Posted May 4, 2012 Share Posted May 4, 2012 Lightning did some trendous damage in the western burbs. Inspected two houses that took direct lightning hits last night. The second of which had the air in the attic superheated so fast, that it blew out all of the soffit around the home as well as dropping drywall ceilings in most of the upstairs. Looked like someone had set a bomb off inside the attic. Link to comment Share on other sites More sharing options...

smoof Posted May 4, 2012 Share Posted May 4, 2012 What a mess in the the flood in the Flint area today, I had to drive my dad to Ann Arbor for some medical checkups and I-75 was closed in both directions each time passing through and the idiot road commision didn't put up any detour signs or routes so I ended up getting lost in the area (i usually just fly through I-75 and just avoid that whole death-hole known as Flint) and trying to find my way through flooded road after flooded road, wasting a couple hours of driving time and gas blah.

I was just about to post that too. I'll be interested to see more of the damage photos and write up when they get back to the office. The bit about the transmission pole is interesting. I'm wondering if it the metal truss tower or just a larger wooden pole, either way looks awfully close to EF3 just based on this house alone.

OceanStWx Posted May 4, 2012 Share Posted May 4, 2012 ^Was that thing moving that slowly - 4.3 miles in 30 minutes? I know it was at least there for four volume scans (roughly 20 minutes). And the initial warning was 17 knot storm motion (20 mph), so maybe a slow down for occlusion towards the end? Link to comment Share on other sites More sharing options...

on_wx Posted May 4, 2012 Share Posted May 4, 2012 Looks like I missed quite the storm yesterday night in Waterloo Region, ON. WATERLOO REGION — Fierce, but short-lived weather pushed through neighbourhoods in Kitchener and Cambridge as a line of thunderstorms hit just after sunset Thursday. Environment Canada doubts any tornadoes touched down during the storm, said meteorologist Peter Kimbell.

cyclone77 Posted May 4, 2012 Share Posted May 4, 2012 Looks like we'll be heading to South Dakota tomorrow based on today's guidance. Maybe northern NE depending on how it shakes out. Still "naderless" this year. Feeling the pressure now that it's May lol. Regarding tonight's MCS. Looks like a WAA wing trying to form in northeast Iowa. Also lots of agitated looking cumulus from the nose of Iowa up to northeast Iowa where that developing WAA wing is. Waterloo, Dubuque, and Cedar Rapids may get plowed by this thing later this evening. Link to comment Share on other sites More sharing options...

Waterloo, Dubuque, and Cedar Rapids may get plowed by this thing later this evening. The MUCAPE gradient runs from about KCCY to KDVN, and that lines up pretty well with the low level Cu field at this time. I think this thing might slip east southeast right along that line. Pretty nice storm relative flow set up for a good cold pool. If we can start to increase those 0-2 km storm relative winds we might really get the winds to crank.

cyclone77 Posted May 4, 2012 Share Posted May 4, 2012 I suspect it will turn more southeasterly before long. Pretty steep dewpoint gradient from near Dubuque down to Rochelle. Dews really drop off east of that line. Link to comment Share on other sites More sharing options...
turtlehurricane Posted May 4, 2012 Share Posted May 4, 2012 Looks like it's coming straight for the Madison-Milwaukee corridor. It's going to advect higher CAPE in from the south so it doesn't matter it's been foggy all day. http://tempest.aos.wisc.edu/radar/wicompflash.html We'll see, convective systems are all sorts of temperamental. Definitely something to watch since it's only 4 counties from being in Wisconsin. Link to comment Share on other sites More sharing options...
