AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
326 PM CDT FRI OCT 10 2014

.DISCUSSION...
SURFACE BASED THUNDERSTORMS ARE OCCURRING THIS AFTERNOON ALONG A
FRONTAL BOUNDARY THAT EXTENDS FROM AN AREA OF LOW PRESSURE NEAR
KADM TO NEAR KMLC AND INTO WEST-CENTRAL ARKANSAS. SOME OF THESE
STORMS ACROSS SOUTHEAST OKLAHOMA COULD BECOME STRONG TO SEVERE
WITH SURFACE BASED CAPE AROUND 1500 J/KG AND LI VALUES AROUND
-5. LARGE HAIL AND WIND GUST TO AROUND 65 MPH WILL BE THE MAIN
CONCERN. THE SEVERE THREAT WILL DIMINISH THIS EVENING AS THE
CONVECTION BECOMES MORE ELEVATED. LOCALLY HEAVY RAIN IS ALSO A
CONCERN WITH THESE STORMS. 1 TO 2 INCHES OF RAIN WILL BE POSSIBLE
WHICH COULD LEAD TO LOCALIZED FLOODING OF LOW LYING AREAS. ADDITIONAL
SHOWERS AND THUNDERSTORM WILL CONTINUE TO BE POSSIBLE OVERNIGHT AND
INTO SATURDAY AS SEVERAL MID-LEVEL SHORTWAVES MOVE ACROSS THE AREA
AND AS THE FRONTAL BOUNDARY SLOWLY MOVES SOUTH AND EAST OF THE AREA.
STILL A CONCERN ABOUT FLASH FLOODING IN THE FAR NORTHWEST ARKANSAS COUNTIES
AS THE GROUND ACROSS THAT AREA IS ALREADY SATURATED. SOME LOCATIONS IN
NORTHWEST ARKANSAS COULD SEE 1 TO 2 INCHES OF RAIN WHICH COULD POSE A
FLASH FLOOD CONCERN. WILL LEAVE THE FLASH FLOOD WATCH IN PLACE FOR TONIGHT
FOR THE NORTHWEST ARKANSAS COUNTIES WHILE DROPPING THE NORTHEAST OKLAHOMA
COUNTIES WHERE LESSER RAIN FALL AMOUNTS ARE ANTICIPATED. THE SHOWERS AND
THUNDERSTORMS ARE EXPECTED TO COME TO AN END SATURDAY NIGHT AS THE MAIN
SHORTWAVE CURRENTLY OVER THE SOUTHWEST UNITED STATES MOVES EAST OF THE
TULSA FORECAST AREA.

THE NEXT CHANCE OF SHOWERS AND THUNDERSTORMS WILL BE SUNDAY NIGHT INTO
MONDAY AS A STRENGTHENING MID-LEVEL SHORTWAVE MOVES OUT OF THE ROCKIES
AND ACROSS THE AREA. THE ASSOCIATED COLD FRONT WILL MOVE THROUGH THE
REGION LATE SUNDAY NIGHT INTO MONDAY MORNING. STRONG TO SEVERE THUNDERSTORMS
WILL ALSO BE POSSIBLE WITH THIS SYSTEM. A SQUALL LINE OF STRONG TO SEVERE
THUNDERSTORMS WILL BE POSSIBLE ALONG THE FRONT AS IT MOVES ACROSS
PORTIONS EASTERN OKLAHOMA AND INTO WESTERN ARKANSAS. THE ACTIVITY IS EXPECTED
TO END MONDAY NIGHT AS THE MID-LEVEL SHORTWAVE MOVES EAST OF THE AREA.

THE REMAINDER OF THE FORECAST IS DRY AS A MID-LEVEL RIDGE DEVELOPS OVER
THE AREA. THE NEXT FRONT IS EXPECTED TO COME THROUGH THE AREA DRY ON
FRIDAY.

DISCUSSION...
RAIN SHOWERS WITH A FEW EMBEDDED THUNDERSTORMS CONTINUE ACROSS
EASTERN OKLAHOMA AND NORTHWEST ARKANSAS EARLY THIS AFTERNOON.
A COLD FRONT WAS LOCATED NEAR THE INTERSTATE 44 CORRIDOR. BREAKS IN
THE CLOUD COVER...SOUTH OF THE FRONT...HAVE ALLOWED THE ATMOSPHERE
TO BECOME MODESTLY UNSTABLE ACROSS SOUTHEAST OKLAHOMA. A FEW STORMS
COULD APPROACH SEVERE LIMITS ACROSS SOUTHEAST OKLAHOMA THIS
AFTERNOON OR EVENING. DAMAGING WINDS AND MARGINALLY SEVERE HAIL
WILL BE THE MAIN THREATS.

IN ADDITION...LOCALLY HEAVY RAINFALL WILL ACCOMPANY THE STRONGER
STORMS WHICH COULD LEAD TO LOCALIZED FLOODING...MAINLY IN AREAS THAT
HAVE ALREADY RECEIVED SIGNIFICANT RAINS. GUSTY NORTH WINDS WILL
DEVELOP THIS AFTERNOON INTO TONIGHT BEHIND THE COLD FRONT ACROSS
NORTHEAST OKLAHOMA.

EXTENDED DISCUSSION...
RAIN SHOWERS ARE EXPECTED TO BE ONGOING ACROSS EASTERN OKLAHOMA
AND NORTHWEST ARKANSAS SATURDAY MORNING...WITH THUNDERSTORM
POTENTIAL REMAINING OVER SOUTHEAST OKLAHOMA AND WEST CENTRAL
ARKANSAS. THIS ACTIVITY SHOULD TAPER OFF FROM WEST TO EAST LATE
SATURDAY AS THE FRONT AND ASSOCIATED UPPER LEVEL LOW PRESSURE
SYSTEM EXITS THE REGION.

THUNDERSTORM CHANCES QUICKLY RETURN SUNDAY AND INCREASE SUNDAY
NIGHT INTO MONDAY AS A STRONG UPPER LEVEL LOW PRESSURE SYSTEM AND
ASSOCIATED COLD FRONT ARE FORECAST TO DIVE SOUTHEASTWARD INTO THE
SOUTHERN PLAINS. INCREASING MOISTURE AND INSTABILITY INTERACTING
WITH THE FRONT WILL ALLOW FOR THE POTENTIAL OF SEVERE WEATHER
SUNDAY NIGHT INTO MONDAY. HEAVY RAINFALL WITH AN ADDITIONAL FLASH
FLOODING POTENTIAL WILL ALSO BE POSSIBLE AS THIS NEXT SYSTEM MOVES
THROUGH...ESPECIALLY ACROSS NORTHEAST OKLAHOMA AND NORTHWEST
ARKANSAS. STAY TUNED TO LATER UPDATES AS THIS TIME NEARS. PLEASANT
FALL WEATHER WILL RETURN BY TUESDAY.
