I know at least one of the tornadoes was at least an EF1, and that is confirmed by an actual wind reading:

From NWS Norman, OK:

0532 PM TSTM WND GST 2 SE NORMAN 35.20N 97.42W
05/10/2010 M64.00 MPH CLEVELAND OK NWS EMPLOYEE

56 KNOT WIND GUST MEASURED BY ANEMOMETER AT NATIONAL
WEATHER CENTER AS FUNNEL PASSED NEARBY.

0533 PM TORNADO 2 SE NORMAN 35.20N 97.42W
05/10/2010 CLEVELAND OK BROADCAST MEDIA

FUNNEL CLOUD WAS ORIGINALLY OBSERVED DESCENDING RAPIDLY
AT 532 PM FROM THE NATIONAL WEATHER CENTER BUILDING.
DAMAGE AND TOUCHDOWN REPORTED JUST EAST OF THE BUILDING
ALONG HIGHWAY 9. TORNADO THEN GREW IN SIZE...SIGNIFICANT
AND LARGE TORNADO STILL ON THE GROUND CAUSING DAMAGE.

0537 PM HAIL STILLWATER 36.12N 97.06W
05/10/2010 E1.75 INCH PAYNE OK EMERGENCY MNGR

0538 PM TORNADO 4 SE NORMAN 35.18N 97.39W
05/10/2010 CLEVELAND OK NWS EMPLOYEE

TORNADO THAT ORIGINALLY TOUCHED DOWN NEAR HIGHWAY 9
CROSSED NEAR HIGHWAY 9 AND 60TH. MEASURED WINDS OF 103
MPH REPORTED BY AN ANEMOMETER AT THAT LOCATION. TIME IS
EXACT. TORNADO DAMAGE ALSO REPORTED.

That touchdown would be very near where I lived in grad school

So, I missed this whole thing completely because I was in Michigan for my grandfather's funeral with no internet access. I knew Monday was going to be a big day, but I had no idea just how big until that afternoon/evening when my phone blew up with text messages from all my friends still in Norman. One of my best friends got baseball-sized hail, and showered with debris from three blocks away.

I haven't even started to work back to my facebook feed from Monday yet. Even reading through this thread today to see how it all really went down was incredible

Right now, from the early surveys, at least 6 tornadoes in NWS Norman territory were rated EF3, and I would guess some of them await a QRT. I think they would be cautious before assigning an EF4 rating on any of them. (I doubt any were EF5)

From what little damage I saw on the weather channel, I would agree with that. Lots of EF3, maybe some borderline EF4. However, without actually being there, it's really impossible to tell for sure. I'll be looking forward to what comes out of this with interest.

IMO, the best chance of an upgrade would be the 1st Norman tornado or the Tecumseh tornado. However, I would want to see how well built they are. I believe buildings in Oklahoma are quite well built usually though...

0221 PM CDT WED MAY 12 2010

AREAS AFFECTED...PARTS OF SERN KS / W-CNTRL OK

CONCERNING...SEVERE POTENTIAL...TORNADO WATCH LIKELY

VALID 121921Z - 122015Z

A LARGE PORTION OF SERN KS EXTENDING INTO W-CNTRL OK IS BEING
MONITORED FOR THE ISSUANCE OF A TORNADO WATCH.

RECENT SATELLITE TRENDS SHOW THE CU FIELD BECOMING MORE AGITATED IN
THE PAST HOUR OR SO--ACROSS THE I-35 CORRIDOR IN S-CNTRL KS AND
N-CNTRL OK AND AREAS IMMEDIATELY TO THE W AHEAD OF A SLOWLY MOVING
BAROCLINIC ZONE. 19Z SURFACE ANALYSIS PLACES A SURFACE LOW OVER
NWRN OK WITH A STALLED SURFACE FRONT LOCATED FROM 10 MI N HUT DRAPED
NEWD TO THE KANSAS CITY METRO. A COLD FRONT EXHIBITING ANAFRONTAL
CHARACTER IS SLOWLY BEGINNING TO PUSH EWD OVER PRATT COUNTY SWWD
INTO NWRN OK AS THE UPSTREAM UPPER TROUGH EJECTS EWD INTO THE SRN
HIGH PLAINS. A COMPLICATING FACTOR TO STORM INITIATION SCENARIO IS
THE EWD PROGRESSION OF A GRAVITY WAVE FROM NEAR EMP SWWD TO CNTRL
OK.

STORMS THAT CAN MOVE OFF OF OR DEVELOP IMMEDIATELY AHEAD OF THE EWD
MOVING COLD FRONT/DRYLINE AND REMAIN S OF THE STATIONARY FRONT IN
THE WARM SECTOR WILL BE CAPABLE OF LARGE HAIL/DMMG WINDS AND AN
ISOLD TORNADO. OTHERWISE...PREVIOUSLY DESCRIBED FRONTAL CHARACTER
ACROSS S-CNTRL KS WILL LIKELY HAVE A DETRIMENTAL IMPACT UPON STORM
LONGEVITY/SEVERITY AS MEAN FLOW IS LARGELY MORE PARALLEL TO THE
FRONTAL BOUNDARY ACROSS THE I-135 CORRIDOR.

REGARDLESS OF FEATURES/MECHANISMS SPAWNING CONVECTIVE INITIATION...A
MOIST/MODERATE TO VERY UNSTABLE AIRMASS /2000-3500 MLCAPE/ ACCORDING
TO 18Z OUN RAOB...IS CONTINUING TO DESTABILIZE WITH THE CAP EXPECTED
TO GRADUALLY WEAKEN TOWARDS MID-AFTERNOON. LOW LEVEL FLOW /AOA 20
KTS 0-1 KM SHEAR/ HAS BEEN NOTED TO BE STRONGER FARTHER N AND E
ACROSS SERN KS SWD INTO CNTRL OK PER RECENT AREA VWP/UPPER AIR DATA.
MORE THAN ADEQUATE SHEAR PROFILES WILL BE SUPPORTIVE OF SUPERCELLS
CAPABLE OF LARGE TO VERY LARGE HAIL...DMGG WINDS...AND ISOLD TORNADO
OR TWO.

I didn't see any damage that approached EF-5 stuff. And probably not much in the way of EF-4 damage either. Lots of EF-3 damage to my untrained eye though.

Question, the big twister filmed by the helicopter (Yukon tornado against the sunny sky to the west) that grew from a funnel to the elephant trunk to a sort-of-a-wedge...what do you think that was?


I'd say defenitely an EF-3 looking storm, maybe an EF-4 storm briefly?

[Texas Snowman]

Tornado watch is up for western Oklahoma and portions of NW North Texas...already a SVTS Warning up in NW Oklahoma.
