AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FORT WORTH TX
400 AM CDT WED AUG 6 2008

.DISCUSSION...

TROPICAL DEPRESSION EDOUARD CONTINUES MOVING WEST THROUGH NORTH
TEXAS. ITS PATH WILL TAKE THE CENTER THROUGH WEST CENTRAL PORTIONS
OF NORTH TEXAS...EXITING THE CWA LATER THIS MORNING. ALTHOUGH
EDOUARD HAS BEGUN PRODUCING SOME MODERATE RAIN SOUTHWEST OF THE
CENTER...AND ITS SPIRAL PATTERN IS CLEARLY EVIDENT ON RADAR...THE
LACK OF SIGNIFICANT NOCTURNAL CORE RAINS SHOWS THE SYSTEM HAS LOST
ITS POTENCY. THE 4 AM ADVISORY FROM HPC NOTES MAXIMUM SUSTAINED
WINDS OF 10 MPH...WITH AN UNIMPRESSIVE MINIMUM CENTRAL PRESSURE OF
29.85 INCHES. REGARDLESS...ANY WELL ORGANIZED AREA OF LOW PRESSURE
INTERACTING WITH UNSTABLE MT AIR WILL MAINTAIN A POTENTIAL FOR
HEAVY RAIN. FWD 00Z SOUNDING SAMPLED THE PERIPHERY OF EDOUARD...PW
VALUES IN EXCESS OF 2 INCHES WILL REMAIN ALONG ITS PATH. THE AREA
OF CONVECTION WILL LIKELY EXPAND IN AREAL COVERAGE WITH THE AID OF
DAYTIME HEATING...BUT THE HIGHEST PRECIPITATION EFFICIENCIES AND
POTENTIAL FOR PROLONGED RAINFALL WILL BE NEAR THE PATH OF EDOUARD
IN SW COUNTIES... GENERALLY BKD-GDJ-ILE AND SOUTHWEST. VORTICITY
OF THE SYSTEM IMPARTED TO INDIVIDUAL CELLS MAY ALLOW FOR A STRONG
STORM...BUT SEVERE THREAT APPEARS LOW. REMAINDER OF CWA WILL SEE
WEAKENING SPEED SHEAR AND LARGELY UNIDIRECTIONAL WINDS ABOVE THE
SURFACE.

DFW AIRPORT HAS SEEN 100 DEGREES OR MORE 17 OF THE LAST 18 DAYS.
THE ONLY DAY THAT FAILED TO REACH TRIPLE DIGITS WAS JULY 24 WHEN
CLOUDINESS FROM DOLLY KEPT HIGHS IN THE 90S. SIMILAR SCENARIO
TODAY AS LOWERED HEIGHTS AND INCREASED CLOUDINESS MAY YIELD BELOW
NORMAL TEMPERATURES THROUGHOUT MUCH OF THE CWA.

ABUNDANT MOISTURE AND WEAKNESS ALOFT MAY LINGER THURSDAY WITH SOME
POTENTIAL FOR AFTERNOON SHOWERS AND THUNDERSTORMS. STILL APPEARS
THAT...AS THE REMNANTS OF EDOUARD SLIDE WEST ALONG THE UNDERBELLY
OF THE UPPER RIDGE...THE RIDGE WILL AMPLIFY SIGNIFICANTLY. THE NW
FLOW INDUCED ACROSS THE SOUTHERN PLAINS MAY ALLOW A NOCTURNAL MCS
TO CROSS THE RED RIVER LATE THURSDAY NIGHT. DEPENDING ON EXTENT
OF PRECIPITATION...AND HOW RAINFALL IMPACTS SURFACE TEMPS...COULD
SEE A COLD FRONT (OR EFFECTIVE FRONTAL BOUNDARY) SLIP INTO NORTH
TEXAS FRIDAY. DO NOT EXPECT SIGNIFICANT DROP IN TEMPS...BUT THIS
MAY HELP DELAY THE RETURN OF TRIPLE DIGIT HIGHS.

WEEKEND AND BEYOND...
ALTHOUGH RIDGING APPEARS SUFFICIENT TO BRING AN END TO RAIN
CHANCES BY THE WEEKEND...RIDGE LOOKS CONSIDERABLY LESS INTENSE
THAN RECENT WEEKS. EXTENDED MODELS HAVE SUBSTANTIAL RUN-TO-RUN AND
MODEL-TO-MODEL INCONSISTENCIES...BUT MODEL SOLUTIONS FAILING TO
RE-ESTABLISH A RIDGE IN EARLY-TO-MID AUGUST REQUIRES CONFLICT WITH
CLIMATOLOGY. ANY PROSPECTS TO TAKE THE EDGE OFF THE HEAT WILL BE
WELCOME NEWS.

.CLIMATE...

DFW CURRENTLY AT 12 CONSECUTIVE DAYS WITH 100 DEGREES OR MORE. ONE
MORE DAY (TODAY) AND THIS STREAK WOULD TIE FOR 10TH LONGEST ON
RECORD...THOUGH THIS APPEARS UNLIKELY.

CURRENT STREAK IS LONGEST SINCE 19 STRAIGHT DAYS IN AUGUST 2006.
