403 PM CDT TUE JUN 18 2013
.DISCUSSION...
SLIGHTLY BELOW AVERAGE AFTERNOON TEMPS ARE IN PLACE ACROSS OK AND
N TX UNDER THE INFLUENCE OF A SURFACE HIGH EXTENDING FROM THE
CENTRAL MIDWEST THROUGH NE OK. A MID LEVEL SHORTWAVE TROUGH AND
REMNANT MCV CONTINUE TO SPAWN THUNDERSTORMS ACROSS NE TX AND INTO
NORTHERN LA. ADDITIONAL MOIST CONVECTION IS ALSO PRESENT ACROSS N
CENTRAL KS AND THE ROCKIES OF CO AND NORTHERN NM ALONG A SFC
TROUGH. COVERAGE WILL LIKELY CONTINUE TO INCREASE LATE THIS
AFT/EARLY THIS EVE AS A SHORTWAVE TROUGH ENTERS CO EARLY THIS
EVENING. IN ADDITION...A CU FIELD HAS DEVELOPED OVER THE TX
PANHANDLE ALONG A STATIONARY FRONT. ITS UNCLEAR WHETHER AN MCS
WILL DEVELOP OFF THE HIGH PLAINS NORTH OF THE PANHANDLE THIS
EVENING AND MOVE INTO OUR NORTHERN ZONES...OR HOW MUCH COVERAGE
WILL DEVELOP ACROSS THE PANHANDLE. HOWEVER...THINK AT LEAST LOW CHC
POPS ARE REASONABLE ACROSS THE NORTHWEST ON THE FRINGE OF THE
RIDGE AXIS THROUGH TONIGHT AND EARLY TOMORROW MORNING. ALSO
INTRODUCED ISO T FOR MOST OTHER LOCATIONS THROUGH 12-18Z TOMORROW
MORNING AS AFOREMENTIONED SHORTWAVE TROUGH AND ASSOCIATED MID
LEVEL COLD POCKET MAY SUPPORT SUCH OVER OUR AREA. SUBSIDENCE WILL
THEN QUICKLY FOLLOW BY MID DAY WED THROUGH EARLY WED AFTERNOON
ACROSS MUCH OF THE AREA.
AN ADDITIONAL MID LEVEL SHORTWAVE TROUGH IS THEN EXPECTED WITHIN
THE SW FLOW ACROSS THE SOUTHERN AND CENTRAL ROCKIES BY EARLY WED
AFTERNOON AND LATE WED NIGHT. AS A RESULT...THUNDERSTORMS WILL
LIKELY REDEVELOP ALONG A LEE SFC TROUGH NEAR EASTERN CO AND THE
PANHANDLES. POPS APPEAR MORE LIKELY (HIGH CHC) ACROSS THE NORTHERN
HALF OF OK BY LATE WED NIGH AND EARLY THURSDAY MORNING AS THIS
FEATURE ROUNDS THE MID LEVEL RIDGE AXIS...AND SLIGHT CHCS MAY
LINGER THROUGH MID DAY THURS ACROSS THE EXTREME EAST/NE HALF OF
OUR FA. A SIMILAR SCENARIO WILL CONTINUE THROUGH THIS
WEEKEND...HOWEVER THE SUBTROPICAL RIDGE SHOULD STRENGTHEN AND MOST
POPS SHOULD REMAIN LIMITED TO WESTERN AND NW OK ALONG THE
NORTHWESTERN FRINGE OF IT WHERE SHORTWAVE TROUGHS WITHIN THE MID
LEVEL SW FLOW ARE EXPECTED. OTHERWISE...EXPECT A WARMING TREND
THROUGH AT LEAST THIS WEEKEND CONSIDERING THE PREVIOUSLY MENTIONED
STRENGTHENING RIDGE.

AREA FORECAST DISCUSSION

306 PM CDT TUE JUN 18 2013
.DISCUSSION...
OVERALL FORECAST HAS NOT CHANGED MUCH FROM THE PREVIOUS ISSUANCE.
MOST OF THE FORECAST WILL REMAIN DRY...AND WILL CONTINUE WITH LOW
CHANCES FOR STORMS WEDNESDAY NIGHT INTO THURSDAY AS THE NORTHERN
ZONES WILL REMAIN AT RISK FOR BEING CLIPPED BY A STORM COMPLEX
THAT TRAVERSES THOSE AREAS ON THE PERIPHERY OF A BUILDING RIDGE.
BEYOND THURSDAY...THE AFOREMENTIONED RIDGE WILL CONTINUE TO BUILD
INTO THE REGION OVER THE WEEKEND. MODELS DECENT AGREEMENT THAT THE
RIDGE WILL FLATTEN OUT SOME...WITH MORE OF A ZONAL FLOW PATTERN
THAT WILL STAY ACROSS THE NRN CONUS. JUST BEYOND THE SCOPE OF THIS
FORECAST...THE UPPER LEVEL RIDGING LOOKS TO STRENGTHEN...WITH THE
CENTER OVER THE ROCKY MOUNTAIN REGION. ANY IMPROVED FLOW THAT
WOULD INCREASE STORM CHANCES LOOKS TO BE WELL REMOVED FROM THE
FORECAST AREA.

CONVECTION REMAINS SOUTH OF OUR FA ACROSS N TX. ALTHOUGH SKIES

RETURN TONIGHT. IN ADDITION...CONVECTION ACROSS WEST TEXAS MAY TRY
TO MAKE ITS WAY INTO OUR TX ZONES LATE TONIGHT. HOWEVER...FEEL
CONFIDENT THAT MOST OF THIS SHOULD REMAIN JUST SOUTH OF OUR FA SO
HAVE ISOLATED HIGHEST POPS TO OUR SOUTHWESTERN BORDERS. A SFC HIGH
UNDER MID LEVEL NW FLOW WILL MOVE OVER THE MIDWEST AND NE OK
TOMORROW KEEPING HIGH TEMPS BELOW AVG. POPS WILL RETURN TO THE
FORECAST LATE TOMORROW THROUGH MID DAY WED AS SHORTWAVE TROUGH
MOVING OUT OF THE ROCKIES ROUNDS THE MID LEVEL RIDGE AXIS. DO NOT
EXPECT A LOT OF PRECIP WITH THIS FEATURE...BUT THINK HIGH CHC POPS
APPEAR REASONBLE FOR MOST LOCATIONS JUST EAST OF THE RIDGE WITH
DEEPER MOISTURE MOVING BACK INTO PLACE.
SIGNFICANT POPS WILL COME TO AN END AFTER WED...BUT DID MENTION
SOME SLIGHT TO LOW END CHCS FOR THURS AM AS ANOTHER MID LEVEL
SHORTWAVE TROUGH TRAVERSES THE NORTHERN ZONES. THIS WILL ALSO BE
TRUE ACROSS THE NW BY FRI AS THE RIDGE SLIDES EAST ALLOWING A FEW
MORE WEAK SHORTWAVE TROUGHS TO MOVE OVER THE PANHANDLE
REGION...AND PERHAPS EVEN AS FAR SOUTH AS CENTRAL OK BY SAT AM.
OTHER THAN THESE LOW END POPS...THE GENERAL TREND WILL BE WARMER

AND HAS LARGELY STABILIZED THE ATMOSPHERE OVER ALL OF EASTERN
OKLAHOMA AND FAR WESTERN ARKANSAS FOR THE TIME BEING. PROFILER
NETWORK ANALYZED AN MCV OVER SE KANSAS WHICH SHOWS UP IN REGIONAL
RADAR LOOP...AND SHORT RANGE MODELS CONTINUE TO SHOW SOME
REDEVELOPMENT CLOSE TO THIS FEATURE DURING THE AFTERNOON MAINLY
NORTH OF U.S. 412. OVERALL THREAT OF ADDITIONAL STORMS SHOULD BE
MINIMAL ELSEWHERE. HAVE UPDATED TO REFLECT THIS AND TO INCORPORATE
MORNING RADAR TRENDS...FORECAST HIGHS OKAY FOR NOW AS ENOUGH
BREAKS IN CLODS EXPECTED FOR THEM TO BE REACHED.

VERY TRICKY AVIATION FORECAST OVER THE NEXT 24 HOURS. THE SQUALL
LINE THAT IMPACTED THE REGION OVERNIGHT CONTINUES TO SHIFT S/SE
THROUGH SRN OK/NRN TX. BEHIND THE LINE OF CONVECTION...A SHIELD OF
STRATIFORM RAIN WITH EMBEDDED THUNDER CONTINUES TO PERSIST...
IMPACTING NEARLY ALL AIRFIELDS ALONG AND EAST OF I-44 AND SOUTH OF
I-40. AS THUNDERSTORMS MOVE SOUTH OF THE AREA INTO NRN TX THIS
MORNING...THERE WILL BE A LULL IN ACTIVITY. WINDS WILL BE BREEZY
AND OUT OF THE NORTH ACROSS NRN OK AND OUT OF THE SOUTH ACROSS SRN
OK/NRN TX FOR MUCH OF THE PERIOD. SCATTERED STORMS WILL BE
POSSIBLE DURING THE DAY...BUT LOW CONFIDENCE IN TIMING/COVERAGE
WILL LEAVE OUT ANY MENTION IN THE TAFS. FOR TONIGHT...SHOWERS AND
THUNDERSTORM CHANCES WILL INCREASE ACROSS WRN/SWRN OK AND WRN N
TX...WITH BETTER CONFIDENCE...DECIDED TO MENTION FOR TAF SITES
ACROSS WRN OK AND WRN N TX.
OVERALL...CIGS AND VIS WILL LIKELY VARY THROUGH THE DAY...BETWEEN
MVFR AND VFR...TO IFR AT TIMES OVERNIGHT IF A SITE IS IMPACTED
DIRECTLY BY A THUNDERSTORM.

A QLCS/SQUALL LINE CONTINUES TO MOVE QUICKLY S/SEWRD ACROSS OKLAHOMA
THIS MORNING...AND CONTINUES TO BE THE MAIN FORECAST CONCERN. ON ITS
PRESENT TIMING/TRACK...THE QLCS WILL REACH THE OKC METRO BETWEEN
0230 AND 0300 AM CDT. THE OVERALL LINE OF CONVECTION IS FAIRLY
VAST...EXTENDING FROM JUST S OF AMARILLO OFF THE CAPROCK...EWD TO I-
40 ALONG THE OK/TX BORDER...NE THROUGH PONCA CITY...AND N INTO SRN
KS. MESONET OBS ALONG THE PATH HAVE CONTINUED TO REPORT 45 TO 55 MPH

POSSIBLE...AND CONTINUE TO BE THE PRIMARY HAZARD. GIVEN ITS
OVERNIGHT HOURS...REPORTS HAVE BEEN SPARSE...BUT THERE WAS A REPORT

MAINTENANCE...WITH GOOD SHEAR/COLD POOL BALANCE WITH 0-3KM SHEAR 0F
20 TO 35 KTS AND MUCAPES 1900 TO 2800 J/KG. THE N/NERN PORTION OF
THE LINE AS IT MOVES THROUGH CENTRAL OK WILL BE THE SECTION TO WATCH
AS CONDITIONS WILL BE MOST FAVORABLE FOR WINDS GREATER THAN 60 MPH.
SFC-600MB THETA E DIFFS WILL BE 20 TO 25 K...WITH THE BEST POCKET OF
MUCAPES RESIDING SWRN THROUGH CENTRAL OK.
AS THE LINE APPROACHES THE RED RIVER VALLEY THROUGH DAWN...IT WILL
BEGIN TO MOVE INTO A LESS FAVORABLE ENVIRONMENT. HOWEVER...RAIN AND
GUSTY WINDS WILL CONTINUE.
THUNDERSTORM CHANCES WILL CONTINUE THROUGH THIS AFTERNOON AS A SFC
FRONTAL BOUNDARY STALLS FROM THE TX PANHANDLE THROUGH SOUTHERN OK.
PRECIP CHANCES WILL CONTINUE THROUGH WEDNESDAY AS THE MID-LEVEL
RIDGE SLOWLY SHIFTS EWD INTO THE HIGH PLAINS...KEEPING A SFC TROUGH
ORIENTED NEAR THE RED RIVER VALLEY.

SEVERE STORM/HEAVY RAINFALL POTENTIAL THROUGH WEDNESDAY...
ESPECIALLY TONIGHT...ARE THE MAIN CONCERNS.
REST OF THIS AFTERNOON AND EVENING...BASED ON LATEST
MODEL GUIDANCE...PARTICULARLY THE HRRR...ISOLATED
TO SCATTERED STORMS WILL DEVELOP JUST NORTH OF I-40 BY
4 PM...THEN CONGEAL INTO A LINE OR CLUSTER AS THEY MOVE SOUTHEAST
AND AFFECT MAINLY THE SOUTH HALF OF OKLAHOMA AND WESTERN NORTH
TEXAS. THE OKLAHOMA CITY METRO AREA WILL BE MOST AFFECTED BETWEEN
4 AND 7 PM. WICHITA FALLS MAY BE AFFECTED 9 TO 11 PM. INCREASED
RAIN CHANCES FOR THESE AREAS.
SOME STORMS WILL BE SEVERE THROUGH TONIGHT WITH DAMAGING WIND UP
TO 70 MPH...LARGE HAIL UP TO HALF DOLLARS...AND VERY HEAVY
RAINFALL OF 1-3 INCHES IN 1-2 HOURS WHICH MAY CAUSE LOCALIZED
FLOODING. DID NOT ISSUE A FLASH FLOOD WATCH AS RAINFALL AMOUNTS
OVER THE LAST SEVEN DAYS HAVE NOT BEEN TOO HEAVY OR WIDESPREAD
ALLOWING FOR SOME DRYING OF THE GROUND. TORNADO POTENTIAL REMAINS
VERY LOW THROUGH TONIGHT. NOT CONFIDENT IF WIDESPREAD SEVERE WILL
OCCUR DUE TO MARGINAL SHEAR.
LATER TONIGHT...ANOTHER LINE OR CLUSTER OF STORMS WILL
LIKELY MOVE INTO OKLAHOMA FROM THE NORTHWEST WITH A SLIGHTLY
LESS DAMAGING WIND/HAIL THREAT...THOUGH HEAVY RAINFALL
AND LOCALIZED FLOODING ARE POSSIBLE. THIS LINE MAY ENTER FAR
NORTHERN OKLAHOMA BETWEEN 10 PM AND 1 AM. THIS LINE MAY WEAKEN
AS IT GETS NEAR AND SOUTH OF I-40 AS THE FIRST LINE/CLUSTER
OF STORMS MAY STABILIZE THE AIR.
MONDAY...SHOWERS AND STORMS MAY LINGER MAINLY NEAR AND EAST
OF I-35 DURING THE MORNING HOURS WITH POSSIBLE REDEVELOPMENT IN
THE AFTERNOON...MOST LIKELY OVER SOUTHERN OKLAHOMA AND WESTERN
NORTH TEXAS WHERE BEST HEATING AND DESTABILIZATION ARE EXPECTED.
SIMILAR TO TONIGHT...A FEW SEVERE STORMS WITH WIND...HAIL...AND
HEAVY RAINFALL ARE POSSIBLE.
MONDAY NIGHT INTO TUESDAY MORNING...THERE IS SOME POTENTIAL
THAT ANOTHER COMPLEX OF STORMS DEVELOPS OVER THE AREA...MAINLY
ACROSS SOUTHWEST OKLAHOMA AND WESTERN NORTH TEXAS...BUT
NOT CONFIDENT THIS WILL OCCUR.
TUESDAY AFTERNOON THROUGH WEDNESDAY MORNING...CONFIDENCE IS
SLIGHTLY HIGHER THAT ADDITIONAL STORMS WILL BE OVER THE AREA...
ESPECIALLY TUESDAY NIGHT AS THE LOW LEVEL JET INCREASES. GUSTY
WINDS...HEAVY RAINFALL...AND FLOODING WILL BE THE MAIN HAZARDS
WITH STORMS.
WEDNESDAY AFTERNOON AND NIGHT...RAIN CHANCES WILL DECREASE
SOUTHWEST TO NORTHEAST AS MID LEVEL CAPPING INCREASES.
THURSDAY THROUGH NEXT SUNDAY...HOT AND RAINFREE WEATHER
CAN BE EXPECTED. TRIPLE DIGIT HEAT WILL LIKELY RETURN TO
PARTS OF WESTERN NORTH TEXAS AND SOUTHWESTERN OKLAHOMA.
HEAT INDICES MAY BE NEAR ADVISORY LEVEL OF 105 DEGREES.
