AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
238 PM CDT FRI AUG 25 2006

.DISCUSSION...RAIN...MORE RAIN...AND COOLER WEATHER WILL BE GOOD
NEWS AS IT ARRIVES THIS WEEKEND. THE CHANGES WILL OCCUR WITH A COLD
FRONT...WHICH WILL REACH NORTHERN OKLAHOMA LATE THIS
EVENING...CENTRAL OKLAHOMA SATURDAY AFTERNOON...AND THE RED RIVER
VICINITY ON SUNDAY.

UNTIL THE FRONT ARRIVES...THE VERY HOT AFTERNOONS AND WARM MORNINGS
HAVE PROMPTED A HEAT ADVISORY FROM INTERSTATE 40 SOUTHWARD. THE
ADVISORY WILL LIKELY BE TRIMMED AWAY FROM THE NORTH AS THE COLD
FRONT MAKES PROGRESS. FIRE WEATHER WILL ALSO BE A CONCERN ON
SATURDAY IN SOUTHERN OKLAHOMA AND WESTERN NORTH TEXAS. THE FORECAST
HUMIDITY AND WINDS BOTH REMAIN MARGINAL FOR RED FLAG CRITERIA IN
TEXAS ZONES...SO WILL LET THE NIGHT SHIFT MAKE THE CALL ON REISSUING
FOR SATURDAY.

THE BIGGER OVERALL STORY WILL BE RELIEF FROM THE HEAT...AND
WIDESPREAD BENEFICIAL RAINFALL. WATER VAPOR IMAGERY SHOWED A STORM
SYSTEM OF SIGNIFICANT STRENGTH FOR THIS TIME OF YEAR...DIGGING
THROUGH THE CENTRAL ROCKIES. INCREASING MID AND UPPER LEVEL FLOW
OVER THE PLAINS WILL LEND BACKGROUND SUPPORT AND ORGANIZATION TO
THUNDERSTORM COMPLEXES FORMING ALONG THE COLD FRONT. THIS TYPE OF
ORGANIZATION IS WHAT HAS BEEN LACKING WITH THE LAST SEVERAL COLD
FRONTS. IN ADDITION...SEVERAL DAYS OF WESTERLY FLOW HAVE CAUSED MID
LEVEL LAPSE RATES TO STEEPEN...WHILE MOIST LOW LEVELS REMAIN IN
PLACE. THIS WILL RESULT IN SUFFICIENT INSTABILITY FOR SEVERE STORMS
TO BECOME A BIT MORE NUMEROUS THAN IN RECENT WEEKS...MAINLY BETWEEN
MID AFTERNOON AND MIDNIGHT...OVER THE NEXT 3 DAYS.

THE FIRST ROUND OF THUNDERSTORMS SHOULD FORM ALONG THE FRONT IN THE
PANHANDLES AND NORTHERN OKLAHOMA THIS EVENING. ALTHOUGH THE SEVERE
THREAT WILL DECREASE AFTER DARK...STORMS SHOULD CONTINUE...AIDED BY
A WELL DEFINED SHORTWAVE TROF MOVING EAST FROM NEW MEXICO...AND A
MOIST LOW LEVEL JET. WITH INDIVIDUAL STORM MOTIONS TO THE
NORTHEAST...AND THE JET PERPENDICULAR TO THE COLD POOL...THE NAM
WIND SHIFT LOOKS REASONABLE...MAKING ONLY SLOW PROGRESS TO THE SOUTH
OVERNIGHT. MODELS SEEM TO HAVE A GOOD HANDLE ON THE UPPER AIR
PATTERN THROUGH SATURDAY...AND SUGGEST DEEP FRONTOGENESIS TO KEEP
OCCASIONAL RAIN GOING TO THE NORTH OF THE FRONT. THE OUTFLOW
BOUNDARY WILL BE ANOTHER FOCUS FOR INITIATION SATURDAY
AFTERNOON...SOMEWHERE IN CENTRAL OKLAHOMA. THIS IS THE TIME PERIOD
IN WHICH STORM MOTIONS APPEAR THE SLOWEST...AND HEAVY RAIN THREAT
APPEARS THE GREATEST...SO HAVE MENTIONED HEAVY RAIN IN THE ZONE
FORECAST.

SUNDAY SHOULD BE EVEN MORE ACTIVE...AS THE MAIN LONGWAVE
TROUGH...AND ITS ASSOCIATED DEEP LAYER LIFTING SWING OUT OF THE
ROCKIES. EXPECT WIDESPREAD ELEVATED THUNDERSTORMS...BECOMING MORE
SURFACE BASED NEAR THE FRONT IN SOUTHERN OKLAHOMA AND WESTERN NORTH
TEXAS. WITH MID AND UPPER FLOW INCREASING...AND BACKED LOW LEVEL
WINDS...AREAS TO THE SOUTH WILL SEE THE BEST CHANCE FOR SEVERE
STORMS...INCLUDING THE POSSIBILITY OF SUPERCELLS PER SPC DAY3
OUTLOOK.

THE TROUGH SHOULD SWEEP THE RAIN CLEAR OF THE AREA BY LATE
MONDAY...SO HAVE REMOVED POPS FOR TUESDAY...BUT NOT BEFORE
WIDESPREAD 1 TO 3 INCH ACCUMULATIONS OCCUR. BEHIND THE STORM...COOL
HIGH PRESSURE LOOKS TO TAKE HIGH TEMPERATURES DOWN INTO THE MIDDLE
80S MONDAY...WITH ONLY A SLOW WARMUP AND DRY WEATHER PERSISTING THE
REST OF THE WEEK.
