Area forecast discussion, Aug 2, 2:45 PM CDT, 1 hour 16 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FORT WORTH TX
245 PM CDT THU AUG 2 2007

.DISCUSSION...
HAVE CONTINUED THE DRYING/WARMING TREND. DID DROP HIGH TEMPS TO
JUST BELOW TRIPLE DIGITS. REASON...MODELS SHOWING WEAK TROPICAL
WAVE ENTERING TX COAST THROUGH THE WEEKEND. WAVE WILL PRODUCE
RAIN TO THE SOUTHEAST OF OUR CWA...NONE UP HERE...BUT WE WILL SEE
ENOUGH HIGH CLOUD FROM THIS SYSTEM TO LIKELY HELP LOWER HIGH
TEMPS JUST A BIT. IN ADDITION...OUR USUAL SUMMER HAS A VERY
SHALLOW MOIST LAYER THAT MIXES OUT DURING THE DAY. DEW POINTS
DROP AS TEMPS RISE...AND THE DRIER AIR HEATS UP QUICKER.
AGAIN...MODELS SHOW MOIST LAYER A BIT THICKER. THIRD FACTOR...ALL
THE GREEN PLANTS WE HAVE...WHICH ARE USUALLY BROWN BY NOW...WILL
ADD THEIR EVAPOTRANSPIRATION MOISTURE TO THE ATMOSPHERE AS WELL.
END RESULT...AFTERNOON HEAT INDICES WILL STILL BE IN THE 105-110
RANGE BUT THE HIGH TEMPERATURE WILL LIKELY STAY A SHADE UNDER
100.       84
