AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIDLAND TX
343 AM CDT TUE AUG 25 1998

OVER LAST SEVERAL HOURS...SATELLITE AND RADAR HAVE INDICATED
IMPRESSIVE NEW CONVECTIVE DEVELOPMENT ALONG NRN PERIPHERY OF
CIRCULATION ASSOCIATED WITH REMNANTS OF CHARLIE. A FLASH FLOOD
WARNING HAS BEEN ISSUED FOR N TERRELL AND FAR E PECOS COUNTIES UNTIL
6 AM CDT. WE ARE MORE INCLINED TO BELIEVE SATELLITE ESTIMATES OF
RAINFALL (SEE RECENT SPENES) THAN OUR DOPPLER RADAR ESTIMATES...
WHICH ARE PROBABLY UNDERESTIMATING AMOUNTS SIGNIFICANTLY DUE TO THE
HIGHLY TROPICAL NATURE OF THIS CONVECTION.

FORECAST PROBLEM IS RAIN THREAT FROM REMNANTS OF CHARLIE. SATELLITE
AND UPPER AIR DATA SHOW UPPER HIGH CENTERED SSW OF BIG BEND...WHICH
MODELS PROG TO MOVE LITTLE TODAY. THIS WILL KEEP FAR SE ZONES IN NW
FLOW ALOFT. MODELS ALSO TRY TO OPEN CIRCULATION ASSOCIATED WITH
CHARLIE (BEST SEEN AROUND 700 MB) TODAY INTO INVERTED TROUGH. BASED
ON FLOW ALOFT...EXPECT CHARLIE TO MAKE LITTLE ADDITIONAL PROGRESS NW
INTO OUR CWA. REMNANTS OF TROPICAL SYSTEMS OVER LAND OFTEN PRODUCE
HEAVIEST RAIN AT NIGHT...SO WE BELIEVE THE HEAVY RAIN THREAT SHOULD
DIMINISH SIGNIFICANTLY LATER THIS MORNING. A FLASH FLOOD WATCH WILL
THEREFORE BE ISSUED UNTIL NOON FOR SE ZONES...INCLUDING CRANE...
UPTON...AND REAGAN COUNTIES...WHICH IS WHERE PRESENT ACTIVITY IS
CURRENTLY HEADING. WILL LEAVE IT TO DAY SHIFT TO ASSESS HEAVY RAIN
THREAT ALONG NRN PERIPHERY OF CHARLIE LATER THIS MORNING.

CONSENSUS WITH OTHERS IS THAT GUIDANCE HAS BEEN OVERDOING POPS OVER
NRN ZONES. WILL UNDERCUT THESE...AND USE A GUIDANCE/PERSISTENCE
BLEND FOR TEMPERATURES. COORDINATED WITH LUBBOCK.
