Area forecast discussion, Apr 26, 3:26 AM CDT, 14 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
326 AM CDT SUN APR 26 2009
.DISCUSSION...
A SURFACE FRONT THAT HAS BEEN THE FOCUS FOR SEVERE CONVECTION AND
POSSIBLE TORNADIC ACTIVITY TO OUR WEST OVERNIGHT HAS MOVED VERY
LITTLE OVER THE PAST 12 HOURS. STRONG STORMS HAVE SO FAR JUST
SKIRTED THE NORTHWEST CORNER OF OSAGE COUNTY DURING THE OVERNIGHT
HOURS. CURRENTLY IT APPEARS THAT THIS ROUND OF CONVECTION WILL
CONTINUE TO SLOWLY TRANSLATE NORTHWARD INTO KANSAS... ALTHOUGH THE
SOUTHERN-MOST CELL IS TRYING TO TRACK DUE EAST... SOUTH OF THE
KANSAS BORDER.
VERY STRONG SOUTHWEST UPPER FLOW IS EXPECTED TO MIX DOWN GUSTS TO
AROUND 40 MPH TODAY ACROSS MUCH OF NORTHEAST OKLAHOMA. THUS WILL
ISSUE A WIND ADVISORY FOR THE AREA IN QUESTION. THE STRONG UPPER
FLOW... COMBINED WITH EMBEDDED RIPPLES IN A BROAD SHORTWAVE TROUGH
WILL CONTINUE TO INITIATE CONVECTION THROUGHOUT TODAY AND MONDAY.
MOST OF THE STRONG ACTIVITY TODAY SHOULD AGAIN BE MOSTLY
ASSOCIATED WITH THE SURFACE FRONT WHICH IS PROGGED TO DRIFT NORTH-
WESTWARD... A LITTLE FURTHER AWAY FROM THE FORECAST AREA.
INSTABILITY ACROSS OUR AREA... WHICH LIES IN THE WARM SECTOR...
REMAINS HIGH. THEREFORE ANY CONVECTION THAT CAN GET GOING TODAY IN
OUR AREA HAS A CHANCE OF REACHING SEVERE LIMITS. LARGE HAIL WOULD
BE THE MAJOR THREAT FROM THIS ACTIVITY.
PRECIPITATION CHANCES WILL INCREASE GREATLY TONIGHT AND INTO MONDAY
ACROSS THE FORECAST AREA. THE FRONT IS PROGGED TO GET A PUSH
SOUTHEASTWARD... FINALLY ENTERING EASTERN OKLAHOMA... WHERE IT WILL
AGAIN SLOW UP. THIS WILL OPEN THE DOOR TO ALL SORTS OF
POSSIBILITIES. DUE TO THE PROXIMITY OF THE FRONT AND ASSOCIATED
POOLING OF INSTABILITY... SEVERE STORMS WILL BE POSSIBLE.
HEAVY RAIN AND WIDESPREAD FLOODING ALSO CONTINUES TO BE A MAJOR
CONCERN MONDAY AFTERNOON/EVENING INTO TUESDAY. MODEL QPF VALUES HAVE
NOT YET REACHED A CONSENSUS AS TO RAINFALL AMOUNTS OR LOCATION. FOR
THIS REASON... WILL CONTINUE TO HOLD OFF ON ISSUING A FLASH FLOOD
WATCH WITH THE EXPECTATION THAT LATER MODEL RUNS WILL PRESENT A
CLEARER PICTURE OF THE IMPENDING THREAT.
THUNDERSTORM CHANCES WILL REMAIN IN THE FORECAST FOR MOST OF THE
WEEK DUE TO MOIST LOWER LEVELS AND INTERMITTENT DISTURBANCES IN THE
FLOW ALOFT. TEMPERATURES WILL REMAIN IN THE VICINITY OF NORMAL
THROUGHOUT THE WEEK.

ONSET...AFTER 7 PM.
DISCUSSION...
A LINE OF THUNDERSTORMS FROM NORTHEAST KANSAS TO SOUTHWEST OKLAHOMA
FORMING NEAR A SLOW MOVING COLD FRONT MAY IMPACT AREAS NORTHWEST
OF TULSA THIS EVENING. AMPLE INSTABILITY AND SHEAR SUGGEST THAT
IF STORMS DO REACH OSAGE AND PAWNEE COUNTIES THIS EVENING THERE IS
A HEIGHTENED SEVERE THUNDERSTORM POTENTIAL WITH SUPERCELLS AND EVEN
POSSIBLE TORNADOES. THE PRIMARY TIME FRAME IS BETWEEN 7 PM AND MIDNIGHT
AS THE LOW LEVEL JET PROVIDES ADDITIONAL FORCING. THE THREAT WILL
DIMINISH AFTER MIDNIGHT.
SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
SPOTTER ACTIVATION MAY BE NEEDED.
.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY.
SUNDAY...SEVERE THUNDERSTORM POTENTIAL...HIGH WIND POTENTIAL.

TUESDAY...THUNDERSTORM POTENTIAL...HIGH WIND POTENTIAL.
WEDNESDAY...THUNDERSTORM POTENTIAL...HIGH WIND POTENTIAL.
THURSDAY...THUNDERSTORM POTENTIAL...HIGH WIND POTENTIAL.
FRIDAY...THUNDERSTORM POTENTIAL...HIGH WIND POTENTIAL.
EXTENDED DISCUSSION...
ACTIVE SOUTHWEST FLOW ALOFT WILL BRING A SERIES OF UPPER LEVEL
IMPULSES ACROSS THE AREA DURING THE UPCOMING WEEK. MOISTURE AND
INSTABILITY WILL REMAIN ABUNDANT ACROSS THE AREA GIVING US A
CONTINUED CHANCE OF THUNDERSTORMS. SEVERE THUNDERSTORMS WILL BE
INCREASINGLY POSSIBLE SUNDAY AFTERNOON...MAINLY ACROSS EASTERN OKLAHOMA.
THE BEST CHANCE OF RAIN WILL BE FROM LATE SUNDAY INTO MONDAY NIGHT
WHEN A COLD FRONT WILL DRIFT SLOWLY SOUTH ACROSS THE AREA. HEAVY
RAIN WILL BE THE PRIMARY THREAT...ALTHOUGH A FEW SEVERE
THUNDERSTORMS APPEAR LIKELY. ONE TO THREE INCHES OF RAIN...WITH
LOCALLY HIGHER AMOUNTS...CAN BE EXPECTED. FLASH FLOODING WILL BE THE
INITIAL PROBLEM...WITH MAINSTREAM RIVER FLOODING AT MID OR
LATE WEEK.
EMERGENCY MANAGEMENT PLANNING STATEMENT...
EMERGENCY MANAGERS SHOULD MONITOR THE LATEST FORECAST. PERIODIC
SPOTTER ACTIVATION MAY BE NEEDED FROM SUNDAY NIGHT THROUGH MONDAY
NIGHT. PREPARATION FOR POSSIBLE FLOODING MAY ALSO BE NEEDED.
