Oh come on now... Had I been a sooner fan and had tickets and I was at the game I'd have been pissed. It was no threat whatsoever...

I have been at several OU games with those kinds of delays. I'm sure there were some people who were unhappy but I never heard anyone say that. I will trust those who have a little more knowledge than me or you about weather threats, thank you anyway.

Slight Risk today...SW OK. Main risk hail.

Wednesday the more widespread day...Slight risk for all of the state except the PH and western two rows of counties.

...SOUTHERN/CENTRAL PLAINS TO LOWER/MIDDLE MO VALLEY...
GIVEN THE LARGE-SCALE EVOLUTION AS PREVIOUSLY DESCRIBED...A COMPLEX
FORECAST SCENARIO IS EXPECTED ON WEDNESDAY...WITH THE POTENTIAL FOR
SCATTERED EARLY-DAY CONVECTION BEING A COMPLICATING FACTOR. CURRENT
THINKING IS THAT LOCALLY HEAVY RAINFALL WILL BE THE MOST COMMON
CONCERN...WHILE A SOMEWHAT MARGINAL SEVERE RISK WILL OTHERWISE EXIST
ACROSS A RELATIVELY BROAD REGIONAL EXTENT. THIS WILL GENERALLY BE
ATTRIBUTABLE TO THE ADVANCEMENT OF THE UPPER TROUGH...A
STRENGTHENING DEEP-LAYER WIND FIELD...AND A MOISTURE-RICH AIRMASS
FOR THE SEASON.


IT IS LIKELY THAT SCATTERED TSTMS WILL BE ONGOING WEDNESDAY MORNING
TO THE EAST OF THE PLAINS COLD FRONT/DRY LINE...INCLUDING A CORRIDOR
FROM OK/NORTH TX INTO KS/MO AND EASTERN NEB/WESTERN IA. THESE STORMS
MAY PERSIST GENERALLY EASTWARD DURING THE DAY. WHILE THE BOUNDARY
LAYER WILL BE QUITE MOIST AND FORCING FOR ASCENT/VERTICAL SHEAR WILL
GENERALLY STRENGTHEN DURING THE DAY...CLOUD COVER/ONGOING
PRECIPITATION WILL LIKELY HINDER THE LIKELIHOOD OF SURFACE-BASED
VIGOROUS CONVECTION. REGARDLESS...AT LEAST A CONDITIONAL/ISOLATED
SEVERE RISK INCLUDING WIND/HAIL WILL EXIST ASIDE FROM THE HEAVY
RAINFALL. ALTHOUGH CONVECTIVE MODE/INSTABILITY DETAILS ARE
UNCERTAIN...A TORNADO RISK CANNOT BE ENTIRELY DISCOUNTED GIVEN
DIURNALLY STRONG LOW-LEVEL SHEAR AND THE MOIST BOUNDARY LAYER.


WHILE MUCH DEPENDS ON EARLY DAY CONVECTION/CLOUD COVER AND
SUBSEQUENT DESTABILIZATION...STRONG/POTENTIALLY SEVERE SURFACE-BASED
DEVELOPMENT MAY OCCUR NEAR THE COLD FRONT AND/OR DRY LINE LATE
WEDNESDAY AFTERNOON/EARLY EVENING IN TANDEM WITH MORE CONSEQUENTIAL
FORCING FOR ASCENT. WHILE HIGHLY UNCERTAIN...THE 00Z NAM APPEARS TO
OFFER THE MOST AGGRESSIVE SCENARIO FOR ADDITIONAL DEVELOPMENT
WEDNESDAY EVENING ACROSS THE SOUTHERN PLAINS. FARTHER NORTH INTO THE
MIDDLE MO VALLEY...THE DEGREE OF DESTABILIZATION IS ESPECIALLY
UNCERTAIN NEAR/EAST OF THE DEEPENING SURFACE LOW AND COLD
FRONT...BUT A LEAST SOME SEVERE RISK MAY BE POSSIBLE WEDNESDAY
AFTERNOON/EARLY EVENING IN THE WAKE OF EARLY-DAY CONVECTION.

Slight risk was pulled down, but still a low risk for an isolated severe storm today. The SPC outlook is pretty interesting on how specific the threat is today based on land formations.

MEANWHILE...FILTERED SUNSHINE WILL OCCUR TODAY ALONG AND S OF
DIFFERENTIAL HEATING BOUNDARY OVER PARTS OF NW TX AND SW THROUGH NE
OK. WHILE LOW-LVL UPLIFT ALONG THIS FEATURE WILL BE WEAK...IT IS NOT
ENTIRELY OUT OF THE QUESTION THAT A STORM OR TWO COULD ARISE ALONG
IT AND/OR ALONG TERRAIN-INDUCED CIRCULATIONS NEAR THE WICHITA MTNS
AND RED RVR. WERE SUCH DEVELOPMENT TO OCCUR...AVAILABILITY OF FAIRLY
RICH MOISTURE /PW AOA 1.25 IN/ AND 30-40 KT WSWLY DEEP SHEAR SUGGEST
A LOW CONDITIONAL RISK FOR SVR HAIL...LOCALLY DMGG WIND...AND/OR A
TORNADO.

DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1228 PM CDT TUE OCT 29 2013


VALID 301200Z - 311200Z


...THERE IS A SLGT RISK OF SVR TSTMS FOR PORTIONS OF THE SRN/CNTRL
PLAINS TO THE MID MO VALLEY...


...SYNOPSIS...
A LARGE UPPER TROUGH WILL PROGRESS EWD OUT OF THE GREAT BASIN...AS
AN ACCOMPANYING BELT OF STRONG SWLY FLOW ALOFT OVERSPREADS THE GREAT
PLAINS. A LEAD SHORTWAVE TROUGH EMBEDDED WITHIN THE LARGE-SCALE
TROUGH WILL MOVE ACROSS NEB AND THE DAKOTAS...WHILE LATER IN THE
PERIOD...THE PRIMARY VORT LOBE ASSOCIATED WITH THE UPPER TROUGH
SPREADS INTO THE SRN PLAINS. AT THE SFC...LOW PRESSURE WILL DEVELOP
NEWD FROM THE CNTRL PLAINS ACROSS THE MID MO VALLEY. AN ATTENDANT
ADVANCING WARM FRONT WILL SPREAD RICH GULF MOISTURE NWD INTO THE
UPPER MS VALLEY. BY LATE IN THE PERIOD...A COLD FRONT WILL
ACCELERATE EWD ACROSS THE SRN/CNTRL PLAINS INTO THE UPPER GREAT
LAKES. WIDESPREAD PRECIPITATION IS LIKELY ACROSS THE CNTRL
CONUS...WITH SOME STRONG TO SVR TSTMS POSSIBLE WHERE POCKETS OF
STRONGER HEATING OCCUR.


...SRN/CNTRL LOWER PLAINS TO MID MO VALLEY...
WIDESPREAD CLOUD COVER AND SCATTERED SHOWERS/TSTMS ARE EXPECTED TO
BE ONGOING AT THE BEGINNING OF THE PERIOD...ESPECIALLY FROM OK NWD
INTO NEB. A SEASONABLY MOIST /PW GENERALLY ABOVE 1 INCH/ AND
RELATIVELY HOMOGENEOUS WARM SECTOR IS EXPECTED TO EVOLVE ACROSS MUCH
OF THE PLAINS...AHEAD OF A COLD FRONT INITIALLY OVER THE CNTRL HIGH
PLAINS...AND A DRYLINE EXTENDING SSWWD FROM S-CNTRL KS INTO W TX.


IT IS LIKELY THAT AT LEAST SOME PRECIPITATION WILL PERSIST
THROUGHOUT THE DAY GIVEN MIDLEVEL HEIGHT FALLS OCCURRING THROUGHOUT
THE PERIOD AND THE PERSISTENCE OF THE LLJ. THIS...ALONG WITH
ASSOCIATED CLOUD COVER...IS EXPECTED TO SUBSTANTIALLY LIMIT THE
AMOUNT OF HEATING AND SUBSEQUENT DESTABILIZATION THAT CAN
OCCUR...AND WILL PROVE DIFFICULT FOR VIGOROUS UPDRAFTS TO DEVELOP.
HOWEVER...IF POCKETS OF HEATING CAN ALLOW TEMPERATURES TO REACH THE
LOWER 70S F...MOIST CHARACTER OF THE BOUNDARY LAYER AND MODERATELY
STEEP LAPSE RATES COULD YIELD MLCAPE VALUES AS HIGH AS 1000-1500
J/KG IN SOME LOCATIONS. VERTICAL SHEAR PROFILES ARE SUFFICIENT FOR
STORM ORGANIZATION AND AN ATTENDANT THREAT FOR HAIL AND WIND...AND
PERHAPS A TORNADO OR TWO...IF MORE ROBUST CONVECTION CAN
DEVELOP...BUT INITIALLY BROAD AND WEAKLY FOCUSED FORCING FOR ASCENT
ACROSS MUCH OF THE SLIGHT RISK AREA YIELDS HIGH UNCERTAINTY
REGARDING POTENTIAL CONVECTIVE EVOLUTION.


THE PRIMARY SFC LOW PRECEDING A LEAD SHORTWAVE UPPER TROUGH ACROSS
THE NRN PLAINS IS FORECAST TO BECOME CENTERED OVER ERN NEB BY
31/00Z...BUT THE DEGREE OF HEATING/DESTABILIZATION THAT CAN OCCUR
INVOF THE LOW IS QUESTIONABLE. BY LATE IN THE PERIOD...CONVECTIVE
RE-DEVELOPMENT IS POSSIBLE AS THE COLD FRONT OVERTAKES THE DRYLINE
FROM WRN OK INTO ERN KS...AND THE PRIMARY VORT LOBE ASSOCIATED WITH
THE UPPER TROUGH PROGRESSES EWD. A MARGINAL WIND/HAIL THREAT COULD
ACCOMPANY THIS ACTIVITY INTO EARLY THU MORNING...BUT THE PRIMARY
RISK SHOULD BE HEAVY RAINFALL.

Last check of the radar, there's nothing out there. Basically it's a 30% chance of precip up until midnight where it jumps to around 50-70% depending on where you are. Pack a poncho just in case ;-)

This is the first time I have ever heard of terrain induced circulations in Oklahoma or anywhere else.....
I would love to hear more about the specifics of such features in Oklahoma.
I have wondered about this for decades and that if it might not be why some areas seem to be hit by tornadoes with more frequency. Maybe I can find something on line someday?

In Colorado there is the Denver Convergence Vorticity Zone (or known locally as the Denver Cyclone) that is caused by the surrounding terrain. The tornado that hit DIA this past June was caused by one of these events.

From Wikipedia:
DCVZ conditions form when a moist, southeasterly air mass meets the Palmer Divide, a ridge that extends east of the Colorado Front Range. If the moist air lifts over the ridge and meets northwesterly winds originating in the Rocky Mountain foothills, winds may converge to create enhanced vorticity. A study conducted between 1981 and 1989 demonstrated that the DCVZ formed on one-third of all days during the convective season (May through August). DCVZ conditions are often associated with the Denver Cyclone effect, which is characterized by the formation of a large gyre near the city center. Several studies have documented the role of the DCVZ in tornado outbreaks across the Denver area. Using climatic data from the 1980s, one researcher has suggested that the presence of a strong June DCVZ has been associated with a 70% chance of zone-area tornado formation.

Slight risk for much of the state today except for the far western section and far eastern sections.

Over the next 24-36 hours there are going to be roughly 3 separate waves. First wave looks like it'll start around 6AM and move out by 1PM. Should remain below severe levels and just have a risk for some hail and gusty winds.

Second round will be late Wednesday increasing overnight. Hail and wind threat there.

Finally the third round will be before daybreak on Thursday with the main storm system.

Constant training thunderstorms/moderate rain just south of the OKC metro.

The developmental zone looks to be lifting north ever so slightly, this will put Norman more solidly into the rain and possible the S metro eventually.


Metro may miss out on heavy rain from the looks of it. Eastern sides of state will get slammed. SE OK could see close to 5 inches in isolated areas.

If we get some clearing over C parts of the state this afternoon, it could spark a round of heavier storms off dryline/triple point in W OK. But for now these clouds are making that look less and less likely.

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 550
CONTINUES.


SUMMARY...WHILE AN ISOLATED SVR STORM IS STILL POSSIBLE...THE
OVERALL SVR THREAT APPEARS LOW OVER THE NEXT SEVERAL HOURS. SOME
ADDITIONAL TSTM DEVELOPMENT IS EXPECTED LATER TONIGHT /AFTER 03Z/.


DISCUSSION...REGIONAL RADAR IMAGERY CONTINUES TO SHOW TSTM ACTIVITY
ALONG AND BEHIND A COLD FRONT DRAPED FROM MCI SWWD TO GAG. DESPITE
DEWPOINTS IN THE MID TO UPPER 60S...MOSTLY CLOUDY SKIES PERSISTED
THROUGHOUT MUCH OF THE DAY...LIMITING HEATING AND RESULTANT
INSTABILITY. MESOANALYSIS CURRENTLY ESTIMATES MLCAPE AROUND 250-500
J/KG ACROSS WRN OK WITH NO MLCAPE INDICATED ACROSS SRN AND ERN KS.
THE LLJ IS EXPECTED TO REMAIN IN PLACE...FOSTERING ISENTROPIC ASCENT
ALONG THE FRONTAL ZONE. AS A RESULT...TSTM ACTIVITY IS EXPECTED TO
CONTINUE ACROSS SERN KS WITH SOME BACKBUILDING POSSIBLE INTO S-CNTRL
KS AND N-CNTRL OK. HOWEVER...GIVEN THE SCANT INSTABILITY...ANY SVR
THREAT ASSOCIATED WITH THIS ACTIVITY IS EXPECTED TO BE ISOLATED AND
MARGINAL. FOR AT LEAST THE NEXT FEW HOURS...ORIENTATION OF THE UPPER
FLOW WILL FAVOR SOME CELL TRAINING WITH A PRIMARY THREAT OF HEAVY
RAIN.


AFTER 03Z...THE UPPER TROUGH ACROSS THE WRN CONUS IS EXPECTED TO
ACCELERATE EWD WITH THE POTENTIAL FOR ADDITIONAL TSTM DEVELOPMENT
ACROSS MUCH OF WRN OK AND SRN KS.
