.DISCUSSION...
WILL GO WITH A BLEND OF NAM/GFS/ECMWF FOR THIS FCST PACKAGE. MADE
VERY LITTLE CHANGES TO THE PREVIOUS FCST...BOTH SHORT AND LONG TERM.

OTHERWISE CDFNT PUSHING INTO THE NRN SECTIONS OF THE CWA ATTM WITH
ONLY SCT SHRA/TSRA ACROSS THE AREA...MAINLY EAST OF I65. THE CDFNT
SHOULD BE OUT OF THE TN VALLEY BETWEEN 12Z AND 14Z WITH CLEARING
SKIES. TEMPS WILL STILL BE ON THE WARM SIDE (MID/UPPER 80S) HOWEVER
THE DEWPOINTS WILL DROP INTO THE LOWER 60S BY THE AFTN. A MUCH LESS
HUMID DAY.

THE DRIER AIRMASS WILL CONTINUE TO OVERSPREAD THE AREA THRU THURSDAY
WITH BELOW NORMAL TEMPS. HIGHS THRU THURSDAY WILL GENERALLY BE IN THE
LOW/MID 80S WITH LOWS IN THE UPPER 50S/ARND 60. WEDNESDAY MRNG LOOKS
TO BE THE COOLEST MRNG WITH LOWS IN THE MID 50S...NOT BAD FOR THE
END OF JULY IN AL. THERE COULD BE A FLY IN THE OINTMENT ON THURSDAY
AS A WEAK UPPER DISTURBANCE IN NW FLOW MAY EFFECT THE CWA...IF GFS IS
CORRECT. ECMWF KEEP DRY CONDITIONS ON THURSDAY.

ECMWF ALSO HINTS AT KEEPING MAINLY DRY CONDITIONS THRU NEXT
WEEKEND...WHERE GFS IS A LITTLE MORE BULLISH WITH THE CHC OF PCPN FOR
NEXT WEEKEND. AS MENTIONED ABOVE WILL NOT MAKE ANY MAJOR CHANGES TO
THE EXTENDED FCST ATTM.
