AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
236 PM CDT SUN AUG 8 2010
.DISCUSSION...
ALTHOUGH WE CONT TO DEAL WITH UPPER RIDGE THAT TRANSLATES BACK AND
FORTH FROM THE ROCKIES INTO THE SOUTHEAST. THERE CONT TO BE MINOR
DISTURBANCES TO GO ALONG WITH DECENT MID LEVEL MOISTURE TO PRODUCE
ISOLATED TO WIDELY SCATTERED SHWRS/TSTMS ACROSS PORTIONS OF THE
AREA. THIS TREND LOOKS TO CONT THE NEXT COUPLE OF DAYS. FOR MON INTO
MON NIGHT UPPER LOW NEAR THE TX COAST WORKS ITS WAY NORTH INTO THE
AREA. THEN BY WED... MODELS SHOW WEAKNESS IN RIDGE ACROSS WESTERN
SECTIONS OF OK INTO THE HIGH PLAINS WITH PERHAPS A WEAK SFC TROUGH
WITH AFTN/EVENING STORM POSSIBILITIES.
FOR THE LATTER PART OF THE WORK WEEK THERE ARE DIFFERENCES IN THE
POSITION OF THE RIDGE... BUT COULD SEE A COUPLE OF WEAK SFC FRONTS
MAKE THEIR WAY INTO THE AREA. THIS WOULD LIKELY RESULT IN
CONTINUATION OF LOW END PRECIP CHANCES.
OTHERWISE WILL MAINTAIN HEAT ADVISORY AND EXTEND IT IN TIME THROUGH
TUESDAY AND WILL HAVE TO CONT TO EVALUATE THE NEED TO EXTEND FURTHER
IN TIME AS TEMPS DO LOOK TO CONT TO FLIRT WITH CENTURY MARK. HOWEVER
MAIN FACTOR WILL BE SFC DEWPOINTS AND WHETHER THEY MIX OUT DURING
THE DAY OR NOT. AT THIS TIME MOST LIKELY AREA TO SEE DEWPOINTS
MAINTAIN HIGH ENOUGH VALUES TO WARRANT ADVISORY WOULD BE NEAR AND
EAST OF I-35.

THIS HAZARDOUS WEATHER OUTLOOK COVERS NORTHERN...WESTERN...
CENTRAL...AND SOUTHERN OKLAHOMA...AND WESTERN NORTH TEXAS.
.DAY ONE...THIS AFTERNOON AND TONIGHT...
THUNDERSTORM OUTLOOK...
THUNDERSTORMS ARE EXPECTED...BUT THE CHANCE OF SEVERE WEATHER
IS VERY LOW.
DISCUSSION...
VARIED TERRAIN...ALONG WITH STRONG HEATING AND WEAK UPPER LEVEL
SUPPORT...SHOULD ALLOW ISOLATED OR SCATTERED THUNDERSTORMS TO
DEVELOP THIS AFTERNOON IN SOUTHEAST OKLAHOMA. SUBSEQUENT OUTFLOW
BOUNDARIES MAY PRODUCE BRIEF SHOWERS AND STORMS FARTHER NORTH AND
WEST...TO NEAR STILLWATER...PURCELL...DUNCAN...AND WICHITA FALLS.
ALTHOUGH VERY ISOLATED...BRIEF HEAVY RAIN WILL REDUCE VISIBILITY...
AND MAY ACCUMULATE TO NEAR ONE INCH IN A SHORT TIME. THE STRONGER
STORMS WILL ALSO PRODUCE CLOUD TO GROUND LIGHTNING AND GUSTY WINDS.
THE ACTIVITY WILL DIMINISH BY MID TO LATE EVENING...ALTHOUGH A FEW
RAIN SHOWERS COULD PERSIST OVERNIGHT NEAR THE RED RIVER.
PROBABILITY TABLE...
VALID THROUGH 700 AM CDT MONDAY AUG 9.
PROBABILITY OF THUNDERSTORMS OCCURRING IN THE
NWS NORMAN COUNTY WARNING AREA...35 PERCENT.
PROBABILITY OF SEVERE STORMS IF STORMS OCCUR...5 PERCENT.
OTHER HAZARDOUS WEATHER...
FOLLOWING MORNING LOW TEMPERATURES IN THE UPPER 70S AND LOW
80S...THE DAY WILL AGAIN BE HOT AND HUMID. HEAT INDICES WILL EXCEED
105 DEGREES ACROSS MUCH OF OKLAHOMA AND PARTS OF WESTERN NORTH
TEXAS...WHERE A HEAT ADVISORY IS IN EFFECT.
.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY...
THUNDERSTORM OUTLOOK...
ON MONDAY A WEAK UPPER LEVEL DISTURBANCE WILL MOVE NORTHWARD FROM
TEXAS. COOLER MID LEVEL AIR OVERSPREADING THE HOT AND HUMID
CONDITIONS AT THE SURFACE...WILL ALLOW FOR A CHANCE OF RAIN
THROUGHOUT THE REGION. THUNDERSTORMS WILL BE WIDELY SCATTERED...AND
MAY BE MORE NUMEROUS WITHIN THE DEEPER LOW LEVEL MOISTURE OVER
WESTERN NORTH TEXAS AND SOUTHERN OKLAHOMA. SOME OF THE ACTIVITY
COULD PERSIST INTO MONDAY NIGHT AS THE DISTURBANCE CROSSES OKLAHOMA.
ANOTHER DAY OF HEATING...AND RESIDUAL COOLER AIR ALOFT WILL AGAIN
YIELD A CHANCE OF LATE DAY THUNDERSTORMS ON TUESDAY...THOUGH WITH
LESS ORGANIZATION THAN ON MONDAY. BY LATE IN THE WEEK...AN UPPER
LEVEL TROUGH WILL BEGIN TO STRENGTHEN OVER THE UPPER MIDWEST STATES.
THIS MAY ALLOW A SERIES OF WEAK COLD FRONTS TO ENTER NORTHERN AND
EASTERN OKLAHOMA BEGINNING THURSDAY...MAINTAINING A LOW...10 TO 20
PERCENT...CHANCE OF THUNDERSTORMS THROUGH SATURDAY.
OTHER HAZARDOUS WEATHER...
EXCESSIVELY HOT AND HUMID WEATHER WILL PERSIST ON MONDAY...AND MAY
LAST FARTHER INTO THE UPCOMING WEEK. A HEAT ADVISORY IS IN EFFECT AT
LEAST THROUGH MONDAY FOR MUCH OF OKLAHOMA AND PART OF WESTERN NORTH
TEXAS. PEOPLE SHOULD REMAIN FAMILIAR WITH HEAT SAFETY TIPS AND LEARN
TO RECOGNIZE SIGNS OF HEAT EXHAUSTION. THE EFFECTS OF A HEAT WAVE
ARE CUMULATIVE...MEANING YOUR RISK FROM HEAT RELATED ILLNESS
INCREASES WITH EACH HOT DAY AND WARM NIGHT THAT PASSES.
THE NEXT SCHEDULED HAZARDOUS WEATHER OUTLOOK WILL BE ISSUED AT 5 AM
MONDAY.
