.DISCUSSION...
WILL BE AMENDING THE ZONES SHORTLY TO LOWER THE PRECIP CHANCES ACROSS
THE FORECAST AREA OVERNIGHT. THE LATEST IR SATELLITE IMAGES AND
SURFACE ANALYSIS DOES INDICATE THAT THERE ARE A COUPLE OF WEAK
BOUNDARIES THAT ARE THE CULPRITS FOR THE WIDELY SCATTERED
SHOWERS/STORMS THAT ARE CONTINUING TO FORM. THE AREAS OF EMPHASIS FOR
SHOWER/STORM DEVELOPMENT ARE TO THE NORTHWEST ACROSS WEST TENNESSEE
AND ACROSS NORTHEAST ALABAMA. HAVE LOWERED POPS INTO THE SLIGHT
CHANCE CATEGORY FOR THE OVERNIGHT FORECAST AND HAVE SLIGHTLY TWEAKED
TEMPS UPWARD IN A FEW LOCATIONS ACROSS THE AREA ALONG WITH DEWPOINT
TEMPS. HAVE ALSO SLIGHTLY LOWERED THE AMOUNT OF CLOUDS ACROSS THE
FORECAST AREA DUE TO IR SATELLITE TRENDING THIS EVENING.
HAVE NOT MADE ANY OTHER CHANGES TO THE GRIDS AND THE ZONES WILL BE
ISSUED SHORTLY.
