.UPDATE...
UPPER LOW CONT TO DOMINATE OUR WX ALONG WITH MESOSCALE FEATURES
TODAY. WILL MAKE SOME MODIFICATIONS TO POPS FOR TODAY AND TWEAK
OTHER GRIDS BASED ON LATEST TRENDS.

MAY BE DIFFICULT TO REALIZE AS MUCH INSTABILITY TODAY COMPARED TO
YESTERDAY AS WEAKER CAP EVIDENT ON MORNING SOUNDING AS AS RADAR CONT
TO SHOW SOME DEVELOPMENT ACROSS AREAS BEHIND LARGER COMPLEX THAT
MOVED THROUGH EARLIER THIS MORNING. HOWEVER MODELS ALSO SHOW CENTER
OF UPPER LOW TRANSLATING SOUTH AND SOUTHEAST INTO WESTERN OK THIS
AFTN... WHICH WILL AID IN MID LEVEL LAPSE RATES... SO SHOULD STILL
SEE SOME HAIL PRODUCING TSTMS. THE 0-1KM AND 0-6KM SHEAR REMAINS
WEAK TODAY... BUT AGAIN IF STORM CAN INTERACT WITH LOW LEVEL
BOUNDARY COULD AGAIN SEE WEAK ISOLATED TORNADO... MAINLY DURING LATE
AFTN INTO FIRST PART OF EVENING AS LLJ DEVELOPS.

UPDATES OUT SHORTLY.

255 AM CDT THU JUN 14 2007

.DISCUSSION...
CONVECTION OVER THE AREA CONTINUES TO WEAKEN AS STORMS ENTER A
REGION OF LESS FAVORABLE INSTABILITY AND SHEAR BUT STORMS ACROSS THE
SOUTHWEST ARE TRAINING DUE TO A NEAR BALANCE OF OUTFLOW AND INFLOW
WHICH IS ALLOWING THE FOCUS FOR REDEVELOPMENT TO MOVE VERY SLOWLY.
THE HOBART MESONET REPORTED 3.45 INCHES OF RAIN IN ONE HOUR EARLIER
WITH THE KFDR RADAR IN GOOD AGREEMENT. KFDR 3-HOURLY RAINFALL
ESTIMATES FOR A SIGNIFICANT PORTION OF KIOWA COUNTY AND PORTIONS OF
OTHER COUNTIES TO ITS NORTH SHOW 6 TO 8 INCHES OF RAIN IN ONLY 3
HOURS EARLY THIS MORNING.

REGARDING TODAYS WEATHER...EXPECT EARLY MORNING CONVECTION TO
DIMINISH BY LATE MORNING WITH RAINFALL RATES DIMINISHING...WITH
REDEVELOPMENT EXPECTED DURING THE AFTERNOON ALONG ASSOCIATED
OUTFLOW/DIFFERENTIAL HEATING BOUNDARIES AND NEAR THE UPPER LOWS
SURFACE REFLECTION OVER WESTERN OKLAHOMA. GIVEN THE EXTENT OF
OVERNIGHT CONVECTION...A REPEAT OF THE RAINFALL EXPERIENCED THE LAST
12 HRS SEEMS UNLIKELY WITH LOWER INSTABILITY AND LOWER PRECIPITABLE
WATER VALUES. HOWEVER...SO MUCH RAIN HAS FALLEN RECENTLY ACROSS
PARTS OF THE WEST WHERE VARIOUS FLASH FLOOD/FLOOD WARNINGS ARE STILL
IN EFFECT...WE WILL BE EXTENDING THE FLASH FLOOD WATCH THROUGH TODAY
FOR AREAS JUST INSIDE THE WESTERN OKLAHOMA BORDER AND MAINLY WEST OF
INTERSTATE 35.

BY TONIGHT...THE UPPER LOW BEGINS DRIFTING SOUTHWARD THROUGH THE
AREA WITH WIDESPREAD BUT POTENTIALLY GRADUALLY LOWER RAINFALL
AMOUNTS AS THE INSTABILITY AXIS PIVOTS SOUTHWARD WITH THE SURFACE
LOW. WILL NOT BE EXTENDING THE FLASH FLOOD WATCH BEYOND TODAY.
RATHER...PREFER TO LET THE MESOSCALE ENVIRONMENT DICTATE THAT
DECISION LATER TODAY OR EVEN EARLY TONIGHT.

PRELIMINARY POINT TEMPS/POPS...
OKLAHOMA CITY OK  85  68  84  67 /  90  70  50  40

A RELATIVELY HIGH PROBABILITY OF SHOWERS AND THUNDERSTORMS INTO THE
WEEKEND.

ACTIVITY... THE POTENTIAL WILL EXIST FOR SOME AREAS TO RECEIVE HEAVY
RAINFALL AND POSSIBLE FLOODING INTO THE WEEKEND.
