AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORMAN OK 645 PM CDT FRI JUN 11 2010 .AVIATION... VFR CEILINGS AND VISIBILITIES EXPECTED TO PREVAIL MOST OF THE FORECAST PERIOD...ALONG WITH STRONG SOUTH/SOUTHEAST WINDS. THE EXCEPTION WILL BE IFR/MVFR CEILINGS MOST TERMINALS BETWEEN 09Z AND 16Z. THE LOWEST CEILINGS ARE EXPECTED TO BE OVER FAR NORTHWEST AND WEST-CENTRAL OKLAHOMA TAF SITES. SCATTERED SHOWERS AND ISOLATED STORMS SOUTH OF KOUN EARLY THIS EVENING MAY IMPACT KOUN BRIEFLY WITH SOME LIGHT RAIN AND VFR CEILING. IMPACTS FROM STORMS WELL SOUTH AND WEST OF OKLAHOMA/WESTERN NORTH TEXAS WILL BE LEFT OUT OF THIS FORECAST AND WILL AMEND IF THEY CAN ORGANIZE AND AFFECT SOUTHWEST OKLAHOMA AND KSPS TERMINALS. && .DISCUSSION... MADE A QUICK UPDATE TO FORECAST TO ACCOUNT FOR NEWER RUNS OF LOCAL WRF AND HRRR MODELS...AND FOR OBSERVATIONAL TRENDS. AT LEAST SOME SUPPORT FOR SCATTERED STORMS OVER SOUTH-CENTRAL AND SOUTHEAST OKLAHOMA THROUGH THE FIRST PART OF THE EVENING...AND AN ISOLATED SHOWER OR STORM CANNOT BE RULED OUT UP TOWARD CENTRAL OKLAHOMA AND THE OKC METRO. SATELLITE TRENDS DO GIVE US CONCERN FOR WHAT THE HRRR AND LOCAL WRF FORECAST WITH REGARDS TO SMALL YET POTENT STORM COMPLEX FORMING OVER THE TEXAS PANHANDLE AND MOVING TO PORTIONS OF WESTERN OKLAHOMA AND WESTERN NORTH TEXAS. WE BUMPED UP OR ADDED POPS FOR THIS EVENING. IF WE DO GET THE FORECAST DEVELOPMENT...POPS WILL NEED TO BE RAISED MUCH HIGHER. && .PREV DISCUSSION... /ISSUED 259 PM CDT FRI JUN 11 2010/ DISCUSSION... WILL LEAVE IN SLIGHT POPS FOR THIS EVENING MAINLY ACROSS WESTERN THIRD OF OKLAHOMA/NW TEXAS. RATHER HIGH INSTABILITY HAS DEVELOPED ACROSS EASTERN PARTS OF THE TX PANHANDLE THIS AFTERNOON BUT WARM TEMPS AT MID-LEVELS MAY SUFFICIENTLY CAP STORM CHANCES. OVERALL SOUTHWESTERLY FLOW WILL CONTINUE TO INCREASE OVER THE WEEKEND AS UPPER TROUGH MAKES SLOW PROGRESS TO THE EAST. DRYLINE ACROSS OKLAHOMA/TEXAS PANHANDLE AND SYNOPTIC BOUNDARY NORTH AND WEST OF THE FA SHOULD LIMIT STORM CHANCES TO NORTHERN AND WESTERN OKLAHOMA SATURDAY INTO SUNDAY. COLD FRONT/OUTFLOW BOUNDARIES SHOULD MAKE BETTER PROGRESS INTO THE FA AS MAIN TROUGH LIFTS NORTH AND EAST MONDAY INTO TUESDAY. APPEARS BEST CHANCE FOR STORMS ACROSS CENTRAL AND SOUTHERN OKLAHOMA WILL OCCUR MONDAY INTO TUESDAY.

THIS HAZARDOUS WEATHER OUTLOOK COVERS NORTHERN...WESTERN...
CENTRAL...AND SOUTHERN OKLAHOMA...AND WESTERN NORTH TEXAS.
.DAY ONE...THROUGH TONIGHT...
THUNDERSTORM OUTLOOK...
ISOLATED SEVERE STORMS ARE POSSIBLE ACROSS OKLAHOMA AND WESTERN
NORTH TEXAS.
LOCATION...
THE GREATEST CHANCES FOR STORMS WILL BE SOUTHERN AND WESTERN
OKLAHOMA...AND WESTERN NORTH TEXAS. THE LOWEST PROBABILITY FOR
STORMS WILL BE OVER NORTH-CENTRAL OKLAHOMA. THE HIGHEST CONCERN FOR
ANY ORGANIZED SEVERE WEATHER WILL BE OVER THE WESTERN THIRD OF
OKLAHOMA AND ADJACENT PARTS OF NORTH TEXAS.
TIMING...
SEVERE STORMS WILL BE POSSIBLE THROUGH MIDNIGHT.
IMPACTS...
HAIL TO THE SIZE OF HALF DOLLARS AND WIND GUSTS TO 60 MPH.
IF WE DO GET THE DEVELOPMENT OF A LARGE THUNDERSTORM COMPLEX THIS
EVENING...HEATBURSTS WILL AGAIN BE POSSIBLE. THE HEATBURSTS COULD
PRODUCE PROLONGED SOUTHERLY WIND SPEEDS OF 40 TO 50 MPH WITH GUSTS
AS HIGH AS 65 MPH. LOCATIONS THAT WOULD SEE THESE IMPACTS WILL BE ON
THE NORTHERN PERIPHERY OF ANY COMPLEX THAT FORMS.
DISCUSSION...
AS A WEAK ATMOSPHERIC DISTURBANCE MOVES NORTHWARD OUT OF SOUTHWEST
TEXAS...ISOLATED TO SCATTERED THUNDERSTORMS WILL BE POSSIBLE OVER
SOUTH-CENTRAL AND SOUTHEAST OKLAHOMA. IF THESE STORMS CAN GET
ORGANIZED...THEY COULD PRODUCE ENOUGH OUTFLOW TO AID IN STORM
DEVELOPMENT ACROSS CENTRAL OKLAHOMA THIS EVENING. ANY STORMS THAT
FORM SHOULD DISSIPATE TOWARD OR WITHIN AN HOUR OF SUNSET.
OTHER STORMS MAY FORM NEAR A DRY LINE OVER THE TEXAS PANHANDLE.
THERE IS A GREATER AMOUNT OF ENERGY AVAILABLE OVER WESTERN OKLAHOMA
AND WESTERN NORTH TEXAS...SO THE RISK OF SEVERE WEATHER WILL BE
HIGHER THAN OVER SOUTH-CENTRAL AND SOUTHEAST OKLAHOMA. LARGE HAIL
AND DAMAGING WIND GUSTS WILL BE THE PRIMARY CONCERNS.
ALTHOUGH THE PROBABILITY IS FAIRLY LOW FOR A LARGE THUNDERSTORM
COMPLEX AGAIN THIS EVENING...IF ONE DOES DEVELOP...THERE WILL BE A
THREAT FOR ANOTHER ROUND OF HEATBURSTS NORTH OF ANY COMPLEX.
PROBABILITY TABLE...
VALID THROUGH 700 AM CDT SATURDAY JUN 12.
PROBABILITY OF THUNDERSTORMS OCCURRING IN THE
NWS NORMAN COUNTY WARNING AREA...60 PERCENT.
PROBABILITY OF SEVERE STORMS IF STORMS OCCUR...30 PERCENT.
OTHER HAZARDOUS WEATHER...
NONE.
.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY...
THUNDERSTORM OUTLOOK...
THUNDERSTORM CHANCES WILL CONTINUE SATURDAY AND SUNDAY PRIMARILY
ACROSS NORTHWEST OKLAHOMA AS A COLD FRONT MOVES TOWARD THE AREA AND
A SLOW MOVING STORM SYSTEM MOVES FROM THE WESTERN UNITED STATES
TOWARD THE GREAT PLAINS. THERE IS A SLIGHT RISK OF SEVERE
THUNDERSTORMS IN NORTHWEST OKLAHOMA ON SATURDAY AND SUNDAY.
THUNDERSTORM CHANCES... ALONG WITH THE POTENTIAL FOR HEAVY
RAINFALL... SPREAD SOUTHEAST ACROSS THE REMAINDER OF THE AREA MONDAY
AND TUESDAY AS THE COLD FRONT MOVES SLOWLY SOUTH.
OTHER HAZARDOUS WEATHER...
HEAT INDEX VALUES OVER 100 WILL CONTINUE ACROSS MUCH OF THE AREA
SATURDAY AND SUNDAY.
THE NEXT SCHEDULED HAZARDOUS WEATHER OUTLOOK WILL BE ISSUED AT 5 AM
SATURDAY MORNING.SPECIAL WEATHER STATEMENT NATIONAL WEATHER SERVICE NORMAN OK 733 PM CDT FRI JUN 11 2010 OKZ040-120045- GARVIN OK- 733 PM CDT FRI JUN 11 2010 ...SIGNIFICANT WEATHER ADVISORY...
