Area forecast discussion, Jul 9, 9:16 PM CDT, 44 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
916 PM CDT MON JUL 9 2007

.DISCUSSION...

WILL LOCALLY CANCEL SEVERE THUNDERSTORM WATCH 500 WITH THIS
UPDATE AS THE AIRMASS ACROSS THE REGION BEGINS TO STABILIZE WITH
THE LOSS OF DAYTIME HEATING. WILL KEEP HIGH POPS OVERNIGHT FOR
MUCH OF EASTERN OKLAHOMA AND PARTS OF NORTHWEST ARKANSAS AS A
THUNDERSTORM COMPLEX IS EXPECTED TO DEVELOP ACROSS SOUTHERN
KANSAS AND NORTH-CENTRAL OKLAHOMA AND MOVE TO THE EAST. THE
THUNDERSTORM COMPLEX IS FORECAST TO DEVELOP NORTH OF A
SURFACE BOUNDARY THAT IS NEAR A KEMP-KGAG LINE AS THE LOW
JET INCREASES AND A MID-LEVEL SHORTWAVE SWEEPS THROUGH THE AREA.

HEAVY RAIN WILL CONTINUE TO BE A CONCERN WITH 1 TO 2 INCHES
OF RAIN POSSIBLE ACROSS PORTIONS OF NORTHEAST OKLAHOMA BY
EARLY TUESDAY MORNING. HAVE OPTED NOT TO ISSUE A FLASH FLOOD
WATCH AT THIS TIME. HOWEVER...THE SITUATION WILL BE MONITORED
CLOSELY.

HAVE MADE SOME MINOR ADJUSTMENTS TO TEMP...QPF AND POP GRIDS
FOR TONIGHT.

&&

.PREV DISCUSSION... /ISSUED 304 PM CDT MON JUL 9 2007/

DISCUSSION...
RAIN EVENT TONIGHT AND TOMORROW IS THE MAIN FORECAST PROBLEM.

STORMS ARE CURRENTLY FORMING OVER CENTRAL OKLAHOMA AND CENTRAL
KANSAS.  THE WRF AND GFS SHOW SIGNS OF CONVECTIVE BLOW UPS IN
THEIR VORTICITY AND QPF FIELDS.  THUS...IT SEEMS LIKE A GOOD
BET IT WILL RAIN. CURRENT THOUGHTS ON QPF WOULD PUT TOTALS
TONIGHT AND TOMORROW IN THE INCH AND A HALF RANGE. SHOULD
IT BECOME OBVIOUS MORE RAIN WILL FALL A FLASH FLOOD WATCH
WOULD BE MERITED.  HAVE DECIDED TO PUT IT OFF BUT USERS WILL
NEED TO MONITOR OUR PRODUCTS TONIGHT.

AFTER TONIGHT THERE WILL BE PERIODIC CHANCES OF RAIN.  THE
MODELS SHOW FRONTS IN THE NEIGHBORHOOD TUEDAY NIGHT AND
WEDNESDAY AND THEN AGAIN THURSDAY NIGHT AND FRIDAY. GIVEN
THE TIME OF YEAR THE CURRENT MODEL TRENDS OF SWEEPING THE
FRONTS THROUGH APPEARS PROBLEMATIC.  IF I TRUSTED THE WRF
I WOULD KEEP WEDNESDAY DRY...BUT THE GFS SUGGESTION OF
CONVECTION SEEMS MORE REASONABLE.  THE SAME SCENARIO OCCURS
FRIDAY INTO SATURDAY.  AT THIS TIME CHOSE TO KEEP SATURDAY
AND SUNDAY DRY BUT THIS MAY NEED REVISITED.

TEMP WISE...CLOUDS AND RAIN WILL BE A FACTOR.  AM A BIT COOLER
THAN MY NEIGHBORS TOMORROW...BUT I THINK THERE WILL BE ENOUGH
RAIN AND CLOUDS TO HOLD THINGS DOWN A LITTLE.  ALL IN ALL DID
NOT STRAY TOO FAR FROM THE MAV AND MEX.
