239 PM CDT THU AUG 10 2006
.DISCUSSION...
ISOLATED SHOWERS AND THUNDERSTORMS HAVE DEVELOPED ACROSS SOUTHERN
KANSAS AND INTO THE NORTHERN PORTION OF THE FORECAST AREA THIS
AFTERNOON. THIS ACTIVITY MAY PERSIST OR BE REGENERATED OVERNIGHT AS
A WEAK UPPER TROUGH TRAVERSES THE CENTRAL PLAINS. WILL MAINTAIN AT
LEAST A SLIGHT CHANCE FOR CONVECTIVE ACTIVITY ACROSS THE FORECAST
AREA TONIGHT THROUGH THE DAY ON SATURDAY IN CONJUNCTION WITH THIS
FEATURE. IN ADDITION... THE CONTINUED HOT WEATHER COMBINED WITH A
MOIST ATMOSPHERE WILL AID REMNANT SURFACE BOUNDARIES IN IGNITING
CONVECTIVE ACTIVITY. BOTH GFS AND WRF ALSO HINT AT A WEAK FRONTAL
BOUNDARY MOVING INTO THE AREA AS WELL... WHICH COULD PROVIDE THE
NECESSARY LIFT FOR THUNDERSTORM INITIATION.
HOT WEATHER WILL CONTINUE ACROSS THE SOUTHERN PLAINS... WITH
TEMPERATURES CONTINUING TO RUN SEVERAL DEGREES ABOVE NORMAL FOR BOTH
THE DIURNAL MAXIMUMS AND MINIMUMS. HOWEVER... THE HEAT IS EXPECTED
TO EASE A BIT FROM THE LEVELS SEEN YESTERDAY AND TODAY AS PERSISTENT
HIGH PRESSURE ALOFT DRIFTS MORE TOWARD THE WEST. THIS WILL KEEP THE
REGION BELOW HEAT ADVISORY CRITERIA AFTER TODAY AND THIS EVENING. AND
WITH RELATIVELY LIGHT WINDS... RED FLAG CRITERIA WILL NOT BE MET
EITHER ALTHOUGH CONSIDERING THE RECENT ABOVE NORMAL HOT WEATHER
AND DRY CONDITIONS... AN ELEVATED FIRE THREAT EXISTS.
SEASONABLY HOT... DRY... AND UNEVENTFUL WEATHER IS EXPECTED TO
CONTINUE THROUGH THE EXTENDED FORECAST PERIOD. LONG RANGE MODELS
HAVE NOT CHANGE APPRECIABLY IN THE PAST 12 HOURS SO HAVE MADE NO
CHANGES TO THE GOING EXTENDED GRIDS.

THIS HAZARDOUS WEATHER OUTLOOK COVERS NORTHERN...WESTERN...
CENTRAL...AND SOUTHERN OKLAHOMA...AND WESTERN NORTH TEXAS.
.DAY ONE...TODAY AND TONIGHT...
THUNDERSTORM OUTLOOK...
ISOLATED SEVERE STORMS WILL BE POSSIBLE... BUT ORGANIZED SEVERE
WEATHER IS NOT EXPECTED.
DISCUSSION...
THUNDERSTORMS DEVELOPING OVER THE CENTRAL HIGH PLAINS THIS AFTERNOON
AND EVENING WILL MOVE SOUTH AND SOUTHEAST TOWARD NORTHERN OKLAHOMA
AS NORTHWESTERLY FLOW DEVELOPS IN THE UPPER LEVELS OF THE
ATMOSPHERE. WITH THE HOT AND DRY LOW LEVEL CONDITIONS... ANY STRONG
STORMS THAT DEVELOP WILL BE CAPABLE OF PRODUCING STRONG WINDS IN
ISOLATED LOCATIONS. WARM MID LEVEL TEMPERATURES AND WEAK WIND SHEAR
WILL LIKELY PREVENT ORGANIZED SEVERE WEATHER AREAS. HOWEVER IF A
THUNDERSTORM COMPLEX DEVELOPS... THE POSSIBILITY OF MORE WIDESPREAD
AND ORGANIZED SEVERE WEATHER WILL INCREASE ACROSS NORTHERN OKLAHOMA
WITH THE PRIMARY THREAT OF STRONG OUTFLOW WINDS. THUNDERSTORM
CHANCES WILL REMAIN QUITE LOW OVER SOUTHERN OKLAHOMA AND NORTH TEXAS.
PROBABILITY TABLE...
VALID THROUGH 700 AM CDT THURSDAY AUG 11.
PROBABILITY OF THUNDERSTORMS OCCURRING IN THE
NWS NORMAN COUNTY WARNING AREA...40 PERCENT.
PROBABILITY OF SEVERE STORMS IF STORMS OCCUR...30 PERCENT.
OTHER HAZARDOUS WEATHER...
A HEAT ADVISORY IS IN EFFECT TODAY... AND APPROPRIATE PRECAUTIONS
SHOULD BE TAKEN FOR THIS PERIOD OF EXCESSIVE HEAT. THE GREATEST HEAT
STRESS WILL OCCUR DURING THE AFTERNOON HOURS AS HEAT INDICES OF 105
TO 110 DEGREES WILL BE COMMON.
VERY HIGH FIRE DANGER WILL CONTINUE ACROSS OKLAHOMA AND WESTERN
NORTH TEXAS THIS AFTERNOON. PLEASE REFER TO THE FIRE DANGER
STATEMENT FOR DETAILS.
.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY...
THUNDERSTORM OUTLOOK...
ANY THUNDERSTORM WHICH OCCUR LATE THURSDAY MAY CONTINUE DURING THE
MORNING HOURS ON FRIDAY. ADDITIONAL OUTFLOW BOUNDARIES PRODUCED
FROM THESE STORMS WOULD PROVIDE A FOCUS FOR REDEVELOPMENT FRIDAY AND
POSSIBLY INTO SATURDAY. OVERALL THUNDERSTORM CHANCES WILL REMAIN
LOW OVER THE WEEKEND INTO NEXT WEEK AS DOMINANT UPPER LEVEL HIGH
PRESSURE ACTS AS A LIMITING FACTOR.
OTHER HAZARDOUS WEATHER...
HEAT RELATED CONCERNS WILL CONTINUE THROUGH THE WEEKEND INTO NEXT
WEEK...AND LATER FORECASTS SHOULD BE CLOSELY MONITORED FOR ANY
ASSOCIATED ADVISORIES. THE PROLONGED PERIOD OF ABOVE NORMAL
TEMPERATURES WILL FURTHER ENHANCE HEAT STRESS FOR PEOPLE AND PETS.
HOT TEMPERATURES AND DRY VEGETATION WILL ALSO RESULT IN A HIGH TO
VERY HIGH FIRE DANGER THROUGH MUCH OF THE EXTENDED OUTLOOK PERIOD.
THE NEXT SCHEDULED HAZARDOUS WEATHER OUTLOOK WILL BE ISSUED AT 7 AM
ON FRIDAY MORNING.In the hours before
