5/15/07 NOW: MI/IN/IL/OH/KY/MO/ONTARIO

The expected Squall Line has materialized from SW Chicago to St. Louis. Thunderstorm Watches extend from NE MO to Central MI. Several SVRs have been issued with the squall lines.

A few rouge storms have popped up ahead of things in South Bend and Elkhart, Indiana receiving SVR. Another nice looking cell is from Lafayette to Monticello, IN but no SVR. North central IN has temps in the mid 80's and dews in the low 60's and both are still climbing.

Currently on IL rt 115 south into Piper City, just intercepted the storms near Herscher, IL, very strong south winds, with blowing dust north toward the storm, had a rather large gustnado cross the road about a mile and half south of us. Now going toward storm in Ford/Mclean county. Maybe some severe hail....

Some weak rotation in the bay county michigan storm right now, 70 knots of shear via. local wnem5 radar and met. during cut in. The bay will be the test to see if it can survive the trip over the cool waters. If nothing else, hail looks likely and its pretty isolated, so structure should be good. Will be going out shortly.

A trained spotter has reported a TOR south of University Park, IL (SW Chicago). Radar wise I don't see anything to warrant any TOR but ground truth prevails.

Just left that Will county storm too......it had good inflow. Now about 4 miles south of Chatsworth, IL. Intense winds from the west, numerous CG's and possible flooding. Whiteout conditions. Trying to get back into town. Pretty intense core. Storm is now severe warned.....calculated a 67 mph gust 4 miles south of Chatsworth, leaves and branches down.

That's the second time now this year that a tornado has struck my home county while I was stuck in the city working. I probably wouldn't have intercepted anything though even if I was out and ready to go. The storm looks very messy on radar, the weak rotation indicated on SRV highly embedded.

Storm rapidly strengthened as it crossed into Huron County and took a right turn. Looks like the main core (73dBZ) will miss Bad Axe to the south as it continues to turn to the SE. I'll be curious to see hail reports out of that storm. Storm now tornado warned. Appears to be some rotation just north of Ubly, by about 2 miles.

LOL...

Had nickel-sized hail at 4:13pm in Clinton Twp (approx 3 miles north of Warren) and then penny-sized hail approx 4:25pm in the same location. I'm so deprived of supercells so far this year... I'm broke :-(

Now: Southern Ontario

Severe thunderstorms firing in Southern Ontario with some very strong hook echos. Hail has been reported from nickle to quarter size.
One tornado has been reported on the ground near London,Ontario.

Pretty damn impressive squall line... Headed to the local lookout point and could view a good majority of the line within Oakland County. People were actually stopping and getting out of their vehicles (in the middle of the road) to view the shelf cloud. Several areas were hanging VERY low, and I'm surprised we didn't get false TOR reports.

Looks like the area around Oakland/Lapeer (Lake Orion to Leonard) really got socked. L2 data showed a solid band of +65 DBz bowing northeast at +55MPH... BVEL showed 60knt winds on the 0.5 tilt, and VIL around 70kg/m2.

Spotter reports in that area will probably be somewhat sparse, but I wouldn't be surprised to see a report or two of +80MPH in that area.
