AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
600 PM CDT SAT JUL 18 2009

.AVIATION...
SHOWERS AND ISOLD TSTMS WILL CONTINUE THIS EVENING. MAIN IMPACTS
WILL BE IN WESTERN PARTS OF THE AREA WITH MORE ISOLATED ACTIVITY
FARTHER EAST. GIVEN THE SPOTTY COVERAGE WILL HANDLE WITH VCTS
THROUGH THE EARLY EVENING WITH GENLY VFR CIGS. ACTIVITY SHOULD
DIMINISH AFTER SUNSET. COULD SEE SOME OVERNIGHT REDEVELOPMENT...ESP
IN THE WEST WITH MID LEVEL WAA DEVELOPING.

&&

.PREV DISCUSSION... /ISSUED 229 PM CDT SAT JUL 18 2009/

.DISCUSSION...
THE CLUSTER OF SHOWERS AND T-STORMS MOVING ACROSS THE RED RIVER
INTO NORTH TEXAS THIS AFTERNOON WILL CONTINUE TO MOVE SSE THROUGH
PORTIONS OF OUR NORTH TEXAS COUNTIES THIS AFTERNOON. BACK TO THE
NORTHWEST... THE MID LEVEL ACTIVITY FROM SW KANSAS INTO THE
EASTERN TEXAS PANHANDLE... OCCURRING NEAR THE UPPER LEVEL JET
AXIS... MAY MOVE INTO THE WESTERN PARTS OF OUR CWA THROUGH
EVENING. MEANWHILE... SHOWERS OVER NORTH CENTRAL OKLAHOMA HAVE
WEAKENED AS THEY ENCOUNTERED SOMEWHAT MORE STABLE AIR.

THE MODELS CONTINUE TO INDICATE A CONTINUATION OF THE NORTHWEST
FLOW ALOFT THROUGH THE UPCOMING WEEK AS OUR AREA REMAINS BETWEEN
THE UPPER RIDGE OVER THE WESTERN US AND THE DOWNSTREAM LONGWAVE
TROUGH ACROSS THE EASTERN THIRD OF THE COUNTRY. THIS SHOULD KEEP
THE EXCESSIVE HEAT AT BAY TO OUR WEST WHILE ALLOWING OCCASIONAL
CLUSTERS OF SHOWERS AND T-STORMS TO DROP SOUTHEAST ACROSS PORTIONS
OF THE AREA.

WE WILL MAINTAIN THE HIGHEST RAIN CHANCES FOR TONIGHT ACROSS THE
WEST AND SOUTHWEST WHERE INCREASING MID LEVEL WARM ADVECTION LATE
TONIGHT WILL COINCIDE WITH THE UPPER LEVEL JET AND SOMEWHAT BETTER
ELEVATED INSTABILITIES. HIGHER RESOLUTION MODELS ARE INDICATING
THE DEVELOPMENT OF A CONVECTIVE COMPLEX OVER THE TEXAS
PANHANDLE... PART OF WHICH COULD TRACK ACROSS OUR SOUTHWEST ZONES
LATER TONIGHT. HOWEVER... A POSSIBLE NEGATIVE FACTOR FOR STORMS
REACHING OUR CWA IS THE OUTFLOW BOUNDARY... CURRENTLY OVER THE
TEXAS PANHANDLE... COULD TEND TO KEEP THE STORM INITIATION AREA
TOO FAR TO THE WEST. WE WILL CONTINUE TO MONITOR THE EVOLUTION OF
THIS ACTIVITY INTO THE EVENING.

FOR SUNDAY... WILL MAINTAIN LOW POPS IN THE WEST DUE TO CONTINUED
WEAK LIFTING SUPPORTED BY MID LEVEL WARM ADVECTION. WILL ALSO ADD
LOW POPS TO THE FAR SOUTH AS THE WARM FRONT IS FORECAST TO MOVE TO
NEAR THE RED RIVER BY AFTERNOON. RAIN CHANCES WILL IMPROVE OVER
MOST OF THE AREA MONDAY NIGHT INTO EARLY TUESDAY AS A COLD FRONT
DROPS SOUTH ACROSS THE AREA.

MILD TEMPERATURES ARE EXPECTED ONCE AGAIN TONIGHT. THE DAYTIME
HIGHS WILL BE WARMING THROUGH MONDAY... BUT STILL RUNNING A BIT
BELOW AVERAGE. SOMEWHAT COOLER WEATHER WILL SPREAD BACK INTO THE
AREA ON TUESDAY BEHIND THE COLD FRONT.

CENTRAL...AND SOUTHERN OKLAHOMA...AND WESTERN NORTH TEXAS.

.DAY ONE...THIS AFTERNOON AND TONIGHT...

THUNDERSTORM OUTLOOK...
ISOLATED SEVERE WEATHER IS POSSIBLE ACROSS WESTERN OKLAHOMA AND
WESTERN NORTH TEXAS.

DISCUSSION...
A THUNDERSTORM COMPLEX WILL MOVE SOUTH THROUGH WESTERN OKLAHOMA AND
WESTERN NORTH TEXAS THIS AFTERNOON. ALTHOUGH SURFACE-BASED
INSTABILITY WILL BE LIMITED... THE COMPLEX SHOULD ENCOUNTER REDUCED
AMOUNTS OF ELEVATED INSTABILITY ONCE IT MOVES INTO WESTERN NORTH
TEXAS...MAKING SEVERE WEATHER UNLIKELY. ALTHOUGH AN ISOLATED SEVERE
STORM IS POSSIBLE EARLY THIS AFTERNOON... ORGANIZED SEVERE WEATHER
IS NOT ANTICIPATED WITH THIS ACTIVITY.

THUNDERSTORM CHANCES WILL CONTINUE TONIGHT ACROSS OKLAHOMA AND
WESTERN NORTH TEXAS AS THE UPPER LEVEL DISTURBANCE MOVES OVERHEAD
AND WARM ADVECTION DEVELOPS AIDING IN GENERATING LIFT FOR
THUNDERSTORM DEVELOPMENT. AGAIN THE MAIN AREA WILL BE ACROSS WESTERN
OKLAHOMA AND WESTERN NORTH TEXAS. MUCH LIKE THE AFTERNOON STORMS...
MOST OF THIS ACTIVITY IS EXPECTED TO REMAIN ELEVATED IN NATURE...
LIMITING THE POTENTIAL FOR SEVERE WEATHER. HOWEVER AN ISOLATED
SEVERE STORM WILL REMAIN POSSIBLE.

VALID THROUGH 700 AM CDT SUNDAY JUL 19.
PROBABILITY OF THUNDERSTORMS OCCURRING IN THE
              NWS NORMAN COUNTY WARNING AREA...100 PERCENT.
PROBABILITY OF SEVERE STORMS IF STORMS OCCUR...30 PERCENT.

OTHER HAZARDOUS WEATHER...
NONE.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY...

THUNDERSTORM OUTLOOK...
A WARM FRONT WILL RETURN NORTH ON MONDAY...AS LOW PRESSURE DEVELOPS
NEAR NORTHWEST OKLAHOMA. ON MONDAY NIGHT AND TUESDAY...A COLD FRONT
WILL OVERTAKE THE WARM FRONT...MOVING FROM NORTHWEST TO SOUTHEAST.
THIS SETUP WILL BE FAVORABLE FOR SCATTERED TO WIDESPREAD
THUNDERSTORMS...AND SOME MAY BE SEVERE.

OTHER HAZARDOUS WEATHER...
NONE.

THE NEXT SCHEDULED HAZARDOUS WEATHER OUTLOOK WILL BE ISSUED AT 5 AM
SUNDAY.
