NATIONAL WEATHER SERVICE TULSA OK
808 PM CDT THU OCT 7 2004

...FLASH FLOOD WARNING CONTINUES FOR TULSA AND EASTERN CREEK         
   COUNTIES UNTIL 900 PM CDT...

AT 808 PM CDT...RADAR CONTINUED TO SHOW SHOWERS WITH A FEW EMBEDDED 
THUNDERSTORMS ALONG A LINE EXTENDING FROM 11 MILES EAST OF TULSA TO 
NEAR SAPULPA...MOVING NORTHEAST AT 20 MPH.  

RADAR INDICATES THAT 4 TO 5 INCHES OF RAIN HAS ALREADY FALLEN OVER 
EASTERN CREEK COUNTY AND CENTRAL TULSA COUNTY.  THE SHOWER AND

EAST OF THE WARNED AREA 900 PM CDT.  THERE HAVE BEEN NUMEROUS 
REPORTS OF STREET FLOODING IN THE CITIES OF SAPULPA AND 
TULSA...INCLUDING SEVERAL ROAD CLOSURES.

MUCH WATER IS ON THE ROADS. IT ONLY TAKES TWO FEET OF RUSHING WATER 
TO CARRY AWAY MOST SPORT UTILITY VEHICLES AND PICKUPS. MOTORISTS 
SHOULD NOT DRIVE THROUGH WATER OF UNKNOWN DEPTH. TAKE A DIFFERENT 
ROUTE TO REACH YOUR DESTINATION OR WAIT UNTIL THE WATER RECEDES.

A FLASH FLOOD WARNING MEANS THAT FLOODING IS IMMINENT OR IS
OCCURRING. RESIDENTS LIVING ALONG STREAMS...CREEKS AND DRAINAGE
DITCHES SHOULD BE READY TO TAKE IMMEDIATE ACTION IF FLOODING IS
OBSERVED. DO NOT ATTEMPT TO CROSS SWIFTLY FLOWING WATER BY FOOT OR BY
AUTO...YOU MAY BE SWEPT AWAY BY THE STRONG CURRENT. IT ONLY TAKES TWO
FEET OF RUSHING WATER TO CARRY AWAY MOST SPORT UTILITY VEHICLES AND
PICKUPS. TAKE A DIFFERENT ROUTE TO REACH YOUR DESTINATION OR WAIT

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OKLAHOMA
305 PM CDT THU OCT 7 2004

ISENTROPIC LIFT AND A MID-LEVEL SHORTWAVE TRAVERSING THE AREA HAVE
COMBINED FORCES TO PRODUCE SCATTERED SHOWERS AND THUNDERSTORMS
ACROSS EASTERN OKLAHOMA AND NORTHWEST ARKANSAS THIS AFTERNOON. LOW
LEVEL MOISTURE SEEMS PLENTIFUL AS SURFACE DEW POINTS HAVE RISEN INTO
THE MID 60S TO LOWER 70S ACROSS MUCH OF THE REGION THIS AFTERNOON.
SOME OF THE THUNDERSTORMS COULD BECOME SEVERE LATE THIS AFTERNOON
AND EARLY THIS EVENING ACROSS WESTERN AND SOUTHERN SECTIONS OF THE
AREA AS CAPE VALUES HAVE RISEN INTO THE 1000 J/KG TO 3000 J/KG
RANGE. LI VALUES ARE ALSO FAVORABLE WITH VALUES IN THE -2 TO -4
RANGE.

THE CHANCES OF SHOWERS AND THUNDERSTORMS WILL REMAIN HIGH THROUGH
FRIDAY ACROSS MUCH OF THE AREA AS ISENTROPIC LIFT CONTINUES TO BE
EVIDENT AND A MID LEVEL TROF REMAINS JUST TO OUR WEST. WILL BEGIN TO
TAPER OFF POPS FROM WEST TO EAST FRIDAY NIGHT INTO SATURDAY AS THE
MID LEVEL TROF BISECTS THE AREA FROM NORTHEAST TO SOUTHWEST.

SOME DRIER AIR WILL MOVE INTO THE REGION FRIDAY NIGHT AND INTO
SATURDAY AS THE LOW LEVEL FLOW BECOMES MORE EAST-NORTHEASTERLY
AS AN AREA OF LOW PRESSURE MOVES ALONG THE SOUTHWEST LOUISIANA
COAST. HOWEVER...WILL KEEP SOME FORM OF POPS IN THE FORECAST THROUGH
SUNDAY AS A MID-LEVEL LOW CUTS OFF OVER SOUTHERN OKLAHOMA. FORECAST
FOR SUNDAY INTO MONDAY IS BASED MORE ON THE GFS MODEL WHICH TAKES
THE LOW IN THE GULF OF MEXICO OFF TO THE NORTHEAST AND INTO LOWER
MISSISSIPPI VALLEY BY SUNDAY NIGHT. POPS WILL NEED TO BE RAISED ON
SUNDAY IF THE ETA IS CORRECT AND THE LOW MOVES INTO NORTHEAST
OKLAHOMA BY SUNDAY NIGHT.

THE MONDAY THROUGH WEDNESDAY TIME FRAME IS EXPECTED TO BE DRY AS
HIGH PRESSURE BUILDS INTO THE AREA AT THE SURFACE AND ALOFT. THE
NEXT CHANCE OF SHOWERS AND THUNDERSTORMS WILL COME AS WE MOVE INTO
WEDNESDAY NIGHT AND THURSDAY AS A STRONG COLD FRONT APPROACHES FROM
THE NORTH. ONLY WENT WITH SLIGHT CHANCE POPS WITH FRONTAL PASSAGE AT
THIS TIME. HOWEVER...POPS MAY NEED TO BE ADJUSTED UPWARD WITH LATER
FORECASTS IF MOISTURE RETURN IS GREATER THAN CURRENTLY INDICATED.
