^My aunt was in her car in that parking lot when it hit and got showered with glass. She's ok though. I'm so glad her car didn't get tossed. She called me in a panic about 5 minutes after it hit saying a tornado went over her car. 

 

I think it was a little weaker by the time it got to my house. I first knew something was up when I noticed debris flying hundreds of feet in the air. There was just a loud "whooshing" sound and I watched it rip right through the front of my subdivision. More than half of the ornamental pear trees along the road into by neighborhood are stubbed/denuded.

Crazy video and pics. At what intensity do cars start flipping over? F1?

Cars aren't one of the damage indicators on the EF Scale, but off the top of my head I can't recall a tornado getting less than EF1 when that type of thing occurs (granted there was probably other evidence to support EF1+ in those cases). It's obviously much easier to flip a high profile vehicle.

No not even t-storm warned.

 

Same thing happened here this morning.  No warning of any type despite velocity scans that looked pretty scary.  DVN confirmed an EF1 touched down in Atkinson IL just south of here.  http://forecast.weather.gov/product.php?site=DVN&issuedby=DVN&product=pns&format=CI&version=1&glossary=1

 

There was another even more impressive couplet that passed through northern Jackson County Iowa north of Maquoketa that wasn't severe/tornado warned.  Have heard there was tree damage up there that was probably tornado related.  Don't know if a damage survey will take place with that one or not.  

 

The EF2 tornado southwest of the QC from the other night wasn't warned until after the tornado report was called in.  These QLCS tornado events have definitely snuck up on several WFOs the last several days.

I saw the SPC report and thought it was quite close to your location. Did you end up chasing that cell or just caught everyone off guard?

Didn't chase it.  Definitely caught most of us off guard.  Really wasn't expecting a severe event anywhere close to this area.  Was surprised to wake up and see an already mature line of storms approaching well before noon.  You could tell there was a chance that some circulations could form on the leading edge of the line of storms just by looping the radar.  Plenty of low-level shear in place along the advancing line of convection.  Chasing this type of event is about impossible so I just stayed put here at home.  Most of the tors that develop with this type of event are very brief, and very hard to warn on.  They're often rain-wrapped as well, which is a big negative as far as chasing.

MESOSCALE DISCUSSION 0802

NWS STORM PREDICTION CENTER NORMAN OK

1109 AM CDT WED MAY 27 2015

AREAS AFFECTED...SRN LOWER MI/E CENTRAL IL/NRN INDIANA/NWRN OH

CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE

VALID 271609Z - 271745Z

PROBABILITY OF WATCH ISSUANCE...60 PERCENT

SUMMARY...STORMS ARE FORECAST TO INCREASE IN COVERAGE/INTENSITY

ACROSS THE SERN UPPER GREAT LAKES AND SWD INTO THE INDIANA/NWRN OH

VICINITY. DAMAGING WIND RISK WILL LIKELY EVOLVE LOCALLY WITH

STRONGER CELLS...WHICH WARRANTS WW CONSIDERATION WITHIN THE NEXT

HOUR OR SO.

DISCUSSION...RECENT WV LOOP REVEALS A VORT MAX CROSSING LK MI INTO W

CENTRAL LOWER MI ATTM...VEERED/UNIDIRECTIONAL -- BUT INCREASING --

FLOW WITH HEIGHT IS OBSERVED JUST S OF THE NEWD TRACK OF THIS

FEATURE...RESULTING IN A WIND PROFILE FEATURING AMPLE SPEED SHEAR

FOR ORGANIZED/BOWING CONVECTION AND ASSOCIATED RISK FOR DAMAGING

WINDS.

HEATING OF THE RELATIVELY MOIST BOUNDARY LAYER /LOW TO MID 60S

DEWPOINTS/ THIS MORNING HAS PUSHED MIXED-LAYER CAPE VALUES TO AROUND

1000 J/KG PER LATEST OBJECTIVE ANALYSES...WHICH HAS BEEN SUFFICIENT

FOR A MARKED INCREASE IN TCU/A FEW CB WITHIN THE PAST HALF HOUR.

WITH STORMS LIKELY TO INCREASE/ORGANIZE OVER THE NEXT COUPLE OF

HOURS...RISK FOR DAMAGING WINDS AND ISOLATED/MARGINAL HAIL MAY

REQUIRE WW ISSUANCE PRIOR TO 27/17Z.

My turn again.

 

 

 

MESOSCALE DISCUSSION 0806
NWS STORM PREDICTION CENTER NORMAN OK
1222 PM CDT WED MAY 27 2015

AREAS AFFECTED...SERN INDIANA/SWRN OH/PARTS OF WRN AND CENTRAL KY

CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE

VALID 271722Z - 271845Z

PROBABILITY OF WATCH ISSUANCE...60 PERCENT

SUMMARY...STORMS ARE FORECAST TO INCREASE IN COVERAGE/INTENSITY THIS
AFTERNOON AHEAD OF AN MCV CROSSING SWRN INDIANA ATTM. RISK FOR
LOCALLY DAMAGING WINDS MAY WARRANT WW ISSUANCE IN THE NEXT HOUR OR
SO.

DISCUSSION...LATEST RADAR AND VISIBLE SATELLITE LOOPS SHOW AN MCV
MOVING NEWD ACROSS SWRN INDIANA ATTM...WITH WITH A GRADUALLY
HEATING/DESTABILIZING AIRMASS ALONG AND S OF THE NEWD TRACK OF THIS
FEATURE. CONVECTION HAS BEGUN TO RE-INTENSIFY ACROSS SRN
INDIANA/WRN KY...AND EXPECT THIS TREND TO CONTINUE OVER THE NEXT
COUPLE OF HOURS.

MODELS SUGGEST THAT FLOW ALOFT WILL GRADUALLY WEAKEN WITH TIME AS
THE UPPER SYSTEM OVER THE UPPER GREAT LAKES REGION CONTINUES
SHIFTING AWAY TO THE NE INTO ONTARIO/QUEBEC. IN THE MEAN TIME
HOWEVER...RISK FOR LOCALLY DAMAGING WINDS MAY BECOME SUFFICIENT --
PARTICULARLY INVOF THE MCV WHERE SOME LOCAL ENHANCEMENT OF THE FLOW
FIELD ALOFT EXISTS -- TO WARRANT WW ISSUANCE.

The second round should've got you there. I was scaped by the first cell, but the second cell seemed to get me and downtown Detroit also very good.

Nope, scraped again on the NW edge.

I'm in NE Detroit BTW.

Only shot now is with the storms around Jackson and Pontiac. Otherwise, screwed again (screwed just within a few miles in every direction too).

Looks like our chances for anything further are squashed.
