854 PM CDT THU JUN 23 2011
.DISCUSSION...
A FEW SHOWERS AND THUNDERSTORMS FORMED OVER NORTHWEST OKLAHOMA
LATE THIS AFTERNOON...AND CONTINUE TO DRIFT SOUTHEAST WITH THE
PREVAILING FLOW ALOFT...AND ALONG THE SOUTHWEST PERIPHERY OF
STRONGER CONVECTIVE INHIBITION. THESE STORMS WILL PROBABLY PERSIST
THROUGH THE EVENING...ALTHOUGH THEIR OVERALL INTENSITY IS EXPECTED
TO DECREASE. HOWEVER...DUE TO WIDE TEMPERATURE-DEW POINT
SPREADS...STRONG WINDS WILL REMAIN A CONCERN UNTIL THE STORMS ARE
COMPLETELY DISSIPATED. SOME ADJUSTMENTS HAVE BEEN MADE TO POP AND
WEATHER GRIDS TO ACCOUNT FOR THESE STORMS.
DUE TO SEVERAL MAJOR WILDFIRES THIS EVENING...PLUS A FORECAST OF
VERY LOW HUMIDITIES/HIGH TEMPERATURES/MODERATE WINDS FOR
TOMORROW...WE ARE CHANGING THE FIRE WEATHER WATCH FOR TOMORROW
INTO A RED FLAG WARNING...WITH A ONE HOUR EARLIER STARTING TIME.

ISOLATED SHOWER/STORMS ACROSS NORTHERN AND CENTRAL OKLAHOMA THIS
EVENING SO WILL MAINTAIN 20-30 PERCENT POPS. WITH THE LARGE
DEWPOINT DEPRESSION AND EXPECTED HIGH BASES... ANY SHOWERS AND
STORMS THAT DEVELOP WILL BE CAPABLE OF PRODUCING GUSTY AND
POTENTIALLY STRONG WINDS.
ATTENTION THEN SHIFTS TO THE HEAT REBUILDING ACROSS THE AREA AND
RELATED FIRE WEATHER CONCERNS. CONDITIONS ARE EXPECTED TO REACH
RED FLAG CRITERIA TOMORROW AFTERNOON IN THE WEST WITH WIND SPEEDS

THIS HAZARDOUS WEATHER OUTLOOK COVERS NORTHERN...WESTERN...
CENTRAL...AND SOUTHERN OKLAHOMA...AND WESTERN NORTH TEXAS.
.DAY ONE...THIS AFTERNOON AND TONIGHT...
THUNDERSTORM OUTLOOK...
ISOLATED SEVERE STORMS ARE POSSIBLE IN NORTHERN AND CENTRAL OKLAHOMA
THIS AFTERNOON AND EVENING.
DISCUSSION...
A WARM FRONT WILL REMAIN DRAPED ACROSS NORTHERN OKLAHOMA THIS
AFTERNOON...ROUGHLY FROM STROUD TO OKEENE TO WOODWARD. MOISTURE AND
WEAK INSTABILITY AT HIGHER LEVELS OF THE ATMOSPHERE WILL MAINTAIN A
FEW THUNDERSTORMS IN NORTHWEST OKLAHOMA EARLY THIS AFTERNOON. THESE
STORMS WILL PRODUCE OCCASIONAL CLOUD TO GROUND LIGHTNING AND WIND
GUSTS APPROACH 40 MPH.
BY LATE AFTERNOON...BROAD SCALE LIFTING WILL REMAIN JUST STRONG
ENOUGH...WHEN COMBINED WITH HOT TEMPERATURES...TO YIELD SOME
STRONGER THUNDERSTORMS. WIDELY SCATTERED STORMS MAY DEVELOP NEAR THE
WARM FRONT...BUT ALSO ALONG THE HIGHER TERRAIN OF FAR WESTERN
OKLAHOMA. WIND SHEAR IS FAVORABLE FOR ORGANIZED STORMS...BUT DRY LOW
LEVEL AIR WILL MINIMIZE INSTABILITY. THE RESULT WILL BE
THUNDERSTORMS WITH VERY HIGH CLOUD BASES...CAPABLE OF PRODUCING
LOCALLY DAMAGING WINDS. MARGINALLY SEVERE HAIL AROUND QUARTER SIZE
IS ALSO POSSIBLE.
DURING THE EVENING...A WARM MID LEVEL CAP WILL EXPAND EAST TOWARD
INTERSTATE 35. THE POTENTIAL FOR NEW THUNDERSTORM DEVELOPMENT WILL
BE CONFINED TO THE EAST OF THE DEVELOPING CAP...MAINLY OVER NORTH
CENTRAL OKLAHOMA. THE THREAT OF SEVERE WEATHER WILL LIKELY END BY
MIDNIGHT.
PROBABILITY TABLE...
VALID THROUGH 700 AM CDT FRIDAY JUN 24.
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...
ALTHOUGH SURFACE WINDS WILL NOT BE ESPECIALLY STRONG TODAY...THE
PRESENCE OF HOT AND VERY DRY AIR WILL LEAD TO ELEVATED WILDFIRE
POTENTIAL THIS AFTERNOON.
.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY...
THUNDERSTORM OUTLOOK...
THUNDERSTORM CHANCES WILL GENERALLY REMAIN VERY LOW FROM FRIDAY
THROUGH THE MIDDLE OF NEXT WEEK. THE HIGHEST CHANCE...AROUND 20
PERCENT...IS FORECAST OVER NORTHERN OKLAHOMA MONDAY NIGHT.
OTHER HAZARDOUS WEATHER...
100 DEGREE HEAT WILL PREVAIL EACH AFTERNOON OVER WESTERN NORTH TEXAS
AND MUCH OF WESTERN OKLAHOMA. HIGHS ALSO REACH 100 OR HIGHER OVER A
LARGER PART OF CENTRAL AND EASTERN OKLAHOMA BY MONDAY. SOME AREAS
WILL LIKELY EXPERIENCE AFTERNOON TEMPERATURES OR HEAT INDICES OF 105
TO 110 DEGREES BY NEXT WEEK. THE PERSISTENT AND PROLONGED HEAT MAY
LEAD TO A SIGNIFICANT INCREASE IN THE POTENTIAL FOR HEAT-RELATED
ILLNESSES.
AT THE SAME TIME...THE POTENTIAL FOR WILDFIRES WILL REMAIN VERY
HIGH...ESPECIALLY IN THE WEST.
