SHORT WAVE ENERGY CURRENTLY TRACKING ACROSS THE TN VALLEY AND
SPARKING SCATTERED CONVECTION ACROSS MUCH OF AL WILL PUSH EAST
TONIGHT. HOWEVER...A WEAK MID-UPR LEVEL SHEAR ZONE GETS LEFT BEHIND
THAT STRETCHES ALONG THE GULF COASTAL SECTIONS BACK TO WEST TX ON
MON. THE AVN AND ETA MODELS ARE IN FAIR AGREEMENT AND HOLD THIS SHEAR
ZONE ACROSS THE FA THRU MON BEFORE SAGGING IT SLIGHTLY SWD AND OVER
THE NRN GULF BY TUE. THIS FEATURE COUPLED WITH A CONTINUED MOIST AND
UNSTABLE AIRMASS WITH 2500+ CAPES...-5 LIS AND 2.0 INCH PWS WARRANT
A CHANCE OF POPS THRU THE FCST PERIOD.  WILL SHOW A SLIGHT DECREASE
IN POPS INTO TUES AS MODELS SHOW A SLIGHT DRYING/MORE STABLE TREND AS
THE UPR LEVEL RIDGE OVER TX BUILDS EAST AND THE SFC RIDGE BUILDS WEST
FROM FL.  HOWEVER...WILL KEEP CHANCE POPS IN THE FCST AS A FRONTAL
BNDRY CONTINUES TO SLOWLY SAG SWD OUT OF NORTH MS-AL ON TUE AND
PROVIDES THE FOCUS FOR MAINLY AFTN-EVNG CONVECTION.  WILL LEAN TOWARD
THE MUCH WETTER AVN POPS AND A SLIGHT WARMING TREND FOR HIGHS BY
TUE.

FOR TONIGHT...EXPECT SCATTERED CONVECTIVE ACTIVITY TO PERSIST THRU
THIS EVENING BEFORE WEAKENING AND PUSHING E-SE BY MIDNIGHT. ALTHO
GROUNDS ARE WELL SATURATED...NO FLOOD PROBLEMS HAVE BEEN REPORTED SO
FAR.  WILL CONTINUE TO HANDLE TONIGHTS ACTIVITY WITH URBAN AND SMALL
STREAM ADVISORIES AND MONITOR FOR THE ISOLATED POTENTIAL FLASH FLOOD
THREAT.

OVER THE COASTAL WATERS...RIDGE BUILDING BACK INTO EASTERN GULF WILL
KEEP A 10-15 KT SOUTHWEST FLOW OVER THE COASTAL WATERS THROUGH TUE.
SCATTERED SHOWERS AND THUNDERSTORMS WILL PERSIST OVERNIGHT WITH
NOCTURNAL INFLUENCES.
