...THE SOUTHEAST...
WIDESPREAD SHOWERS AND EMBEDDED THUNDERSTORMS CONTINUE ACROSS PARTS
OF FL/SERN GA AND INTO SC...NEAR AND AHEAD OF A COLD FRONT WHICH
CONTINUES MOVING SEWD ACROSS THIS REGION. MODEST INSTABILITY AND
MINIMAL SHEAR SUGGEST LITTLE SEVERE POTENTIAL...THOUGH AN ISOLATED
STRONGER GUST OR 3/4 INCH HAILSTONE WILL REMAIN POSSIBLE WITH ONE OR
TWO OF THE MOST VIGOROUS STORMS OVER THE NEXT COUPLE OF HOURS
BEFORE STORMS UNDERGO FURTHER DIURNAL WEAKENING.
...S CENTRAL AZ...
SHOWERS AND A FEW STRONGER THUNDERSTORMS ARE ONGOING ACROSS
AZ...WHERE MARGINAL CAPE IS INDICATED ATOP A DEEP/WELL-MIXED
BOUNDARY LAYER. A WEAK WAVE MOVING WWD ACROSS SRN AZ -- APPARENT AS
A ZONE OF MOISTENING IN THE LATEST WV LOOP -- APPEARS TO BE
ENHANCING THE CONVECTIVE ACTIVITY. WHILE ANY SEVERE POTENTIAL
SHOULD REMAIN MINIMAL...AN ISOLATED STRONGER/POSSIBLY SEVERE GUST
COULD OCCUR THROUGH MID-EVENING...GIVEN DEEP INVERTED V-TYPE
PROFILES SUPPORTIVE OF STRONG SUB-CLOUD EVAPORATION.
