NATIONAL WEATHER SERVICE NORMAN OK
346 AM CDT SUN AUG 14 2005
...CORRECTED START TIME OF FLASH FLOOD WATCH...
.DISCUSSION...
WE WILL BE ISSUING A FLASH FLOOD WATCH FOR TODAY FOR MUCH OF
SOUTHWEST OKLAHOMA INTO PORTIONS OF SOUTH CENTRAL OKLAHOMA AND FOR
ALL OF OUR NORTH TEXAS COUNTIES. THE SLOW MOVING FRONT... WHICH IS
BEING SOMEWHAT MASKED BY SEVERAL OUTFLOW BOUNDARIES... WILL CONTINUE
TO PROVIDE SUPPORT FOR SHOWERS AND TSTMS OVER THE AREA TODAY. WITH
PRECIPITABLE WATER AMOUNTS APPROACHING 2 INCHES...LOCALLY HEAVY
RAINFALL WILL BE POSSIBLE. THE BEST CHANCE FOR HEAVY RAINS ARE
EXPECTED TO BE ACROSS PORTIONS OF SOUTHERN OKLAHOMA INTO NORTH
TEXAS. FOR NOW... THE NORTHERN PART OF THE FLASH FLOOD WATCH ALSO
EXTENDS NORTH INTO BECKHAM AND WASHITA COUNTIES. ALTHOUGH THESE
AREAS WILL LIKELY NOT SEE THE HEAVIEST RAINS... WE HAVE INCLUDED
THEM BECAUSE OF EXCESSIVE ANTECEDENT RAINFALL... AND THUS A REDUCED
FLASH FLOOD THRESHOLD. KTLX RADAR APPEARS TO BE UNDERESTIMATING
RAINFALL AMOUNTS BY ABOUT A THIRD. WEAK WAVES MOVING THROUGH THE
SOUTHERN PLAINS TODAY WILL ALSO PROVIDE SOME FORCING... AS WILL THE
JUXTAPOSITION OF THE RIGHT REAR QUADRANT OF THE UPPER LEVEL JET
ACROSS THE AREA. RAIN CHANCES WILL REMAIN FAIRLY HIGH TONIGHT AND
MONDAY... BEFORE TAPERING OFF ON TUESDAY. WE CURRENTLY HAVE THURSDAY
DRY... BEFORE INCREASING AGAIN BY LATE IN THE WEEK AS ANOTHER FRONT
APPROACHES THE AREA. HOWEVER... THE LATEST RUN OF GFS80 IS SLOWING
DOWN PROGRESS OF THIS COLD FRONT COMPARED TO THE OTHER MODELS. AT
THIS POINT... WE WILL NOT MAKE ANY DRASTIC CHANGES IN TIMING OR POPS
UNTIL WE GET A LITTLE MORE CONSISTENCY IN THE TIMING OF THIS NEXT
SYSTEM.
THE CLOUDS AND PCPN WILL RESULT IN COOLER TEMPS TODAY... ALTHOUGH
LOCATIONS THAT SEE SOME SUN... MAINLY IN THE SOUTHEAST... COULD
JUMP UP SEVERAL DEGREES DURING THE AFTERNOON. TEMPS WILL WARM UP
AGAIN IN MOST AREAS BY MID WEEK.

Rainfall totals of 4 to 8+ inches over the Arbuckle Mountains in Murray County in south central Oklahoma during the overnight hours of August 14-15 triggered heavy runoff and flash flooding in Turner Falls Park. The flash flooding washed away beaches at Turner Falls, and eroded the bank near a building just downstream of the waterfall. Some campers were forced to evacuate from the park, while other campers became stranded when a low water crossing across Honey Creek, downstream of Turner Falls and 4 miles south of Davis, OK, became impassible during the morning of August 15.A USGS river gage station located near the low water crossing recorded a significant rise for Honey Creek during the event. The 4-8 inch rainfall totals on August 14-15 produced a flood crest 3.5 feet higher than the low water crossing elevation. Low stages at the site are usually around 1.4 feet, but a crest of 4.9 feet occurred at 4:00 am CST on August 15.The flash flooding deposited brush and debris along the Honey Creek, and 150 tons of sand were delivered to the area to rebuild washed-away beaches., The City of Davis, which owns the park, was forced to close it for about a week while repairs were made.
Riverine flooding was also seen in south central Oklahoma in mid August along Mud Creek in Stephens County. Heavy runoff from storm total rainfall amounts of 4-8+ inches caused Mud Creek to overflow its banks and produce moderate flooding during a broad crest August 15-20. Mud Creek crested at 27.1 feet, 7.1 feet above flood stage, at 12:00 pm CST on August 17 at the USGS river gage site near Courtney, OK. Mud Creek remained above flood stage from 2:30 am CST on August 15 to 3:00 am CST on August 20. Croplands and some secondary roads along Mud Creek were flooded during this period.
