Caddo County storm is splitting like the earlier one in Comanche County. Northern cell is going to move into Tuttle here shortly.

Elevated cell now between Hwy 9 and Etoawah Road...near 96th Ave SE south of Lake T Bird. Mainly just a lot of noise and lightning right now.

Another cell going up between Shawnee and Tecumseh.

Cell moving towards Tuttle has hail estimated at 0.65" right now. Hail core is on the Northern side of the storm.

AREAS AFFECTED...SRN OK...FAR N TX

CONCERNING...SEVERE THUNDERSTORM WATCH 68...

VALID 310114Z - 310245Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 68
CONTINUES.

SUMMARY...THE THREAT FOR ISOLATED LARGE HAIL AND LOCALIZED STRONG
WIND GUSTS CONTINUES NEAR-TERM BUT SHOULD GRADUALLY DIMINISH THIS
EVENING AS NOCTURNAL COOLING OCCURS WITHIN A VERY WEAKLY-FORCED
ENVIRONMENT.

DISCUSSION...A CONVOLUTED SURFACE PATTERN PERSISTS WITH SEVERAL
SMALL-SCALE CONVECTIVE OUTFLOWS AND PRE-FRONTAL TROUGHS AHEAD OF A
STRONGER COLD FRONTAL SURGE EXPECTED LATER TONIGHT. MODIFIED 00Z FWD
RAOB AND PURCELL OK PROFILER SUGGESTS PRESENCE OF 1500 J/KG MLCAPE
AMIDST 35-40 KT DEEP-LAYER SHEAR WILL CONTINUE TO SUPPORT ISOLATED
SUPERCELLS FROM ALONG THE RED RIVER NEWD INTO ERN OK.
HOWEVER...ANEMIC LOW-LEVEL FLOW...EVEN DIFFLUENT IN PARTS OF S-CNTRL
OK/N-CNTRL TX...SHOULD REMAIN THE PRIMARY LIMITING FACTOR TO
RE-INTENSIFICATION/SUSTENANCE OF LARGE HAIL POTENTIAL BEYOND THE
NEXT COUPLE OF HOURS AS THE BOUNDARY LAYER COOLS AND MLCIN SLOWLY
INCREASES. THIS SCENARIO IS SUPPORTED BY 21-22Z HRRR RUNS WHICH
DEPICT CONVECTION DIMINISHING SUBSTANTIALLY BY 03-04Z.

Things in Central OK are settling down. Last storm SE of Chickasha is still severe but weakening as well. That'll wrap up the updates for now. :)

Latest HRRR has storms start to fire between 1 and 3AM over the Western Half of the state (mainly I-40 and north). Quickly evolving into a large MCS diving to the ESE.

Loop (http://rapidrefresh.noaa.gov/HRRR/jsloopLocalDiskDateDomain.cgi?dsKeys=hrrr_jet:&runTime=2013033101&plotName=cref_t5sfc&fcstInc=60&numFcsts=16&model=hrrr&ptitle=HRRR%20Model%20Fields%20-%20Experimental&maxFcstLen=15&fcstStrLen=-1&resizePlot=1&domain=t5)

And so OKC has a 90% chance of showers and thunderstorms mainly after 2 am. Some may be severe.

Bectcha a pizza it misses us completely.

Update HRRR forecast from 5AM. One storm is out there right now moving into Roger Mills County, but so far that's it. Looks like main batch of storms gets going around 3AM in West Central OK.

Bectcha a pizza it misses us completely.

There will surely be at least a sprinkle, or two.

Dog just got up in bed with us. That usually means thunder in El Reno.

Storms rapidly firing in W and NW OK. Moving ESE.

Our baby was up from 1:30 till now, just as happy as he could be. I figured the weather had to of been changing.

Looks good just north and west of OKC area. ...just happen to be in Tulsa

Well, all that grass seed I put down the other day, GONE!

Raining HEAVILY in the quail creek area

Here comes the rain - East of Mustang.

Correction - SERIOUS hail. Sounds like cannonballs.

Main area of hail right now below. Also showing a strong inflow area near 134th and Rockwell, so damaging wind threat is going up.

http://www.weatherspotlight.com/screencap/ktlx_20130331_grab2.png

mPING hail report of 1.75" in Mustang.

Radar estimated hail size now up to 2.29".

I'd agree with the hail size. Jeeze! Seems to be passed, now. Three of my neighbors just got new roofs from previous hail damage. I don't even want to look at our roof and the old van parked outside.

Looks like the hail core is riding along and to the west of US 77, so most of Central and Eastern Norman might avoid the hail.

Here is the current overlay of the PING reports from NSSL with hail sizes reported as it came through Norman.

http://www.weatherspotlight.com/screencap/ktlx_20130331_grab5.png

Got quarter-sized hail in Central Norman, but had friends in the SW part of Norman (from campus westward) with up to 2.00" hail and damage. One had lawn chairs destroyed, and the other reported that every car in her lot was dented. Both Westheimer and the Mesonet gusted up to 59MPH as well.

The first photo is hail on the porch of my shed 8 hours after the storm passed, with an air temp of 60 degrees. I was out there at 4:30AM and the amounts were not to be believed. This is east of 24thNW and Lindsey.

I was tempted to have bet that the storms would bypass Stillwater as radar was looking like the system was going to neatly split to the north and south of Stillwater, which is how it turned out to be. Much of Tulsa area didn't get a drop, either. Most of the SE quarter of Oklahoma did pretty good with handsome rain amounts.

Green is the season between April 29th and May 2nd.
