.DISCUSSION...

CURRENT-TONIGHT...WEAK SURFACE RIDGE WILL KEEP A DRY AND STABLE
AIRMASS ACROSS THE REGION TONIGHT. ACTIVE SOUTHERN STREAM JET
OVERHEAD WILL CONTINUE BRINGING IN ABUNDANT HIGH CLOUDS. RADAR
ECHOES OBSERVED OFF THE WEST COAST OF FLORIDA ARE LIKELY VIRGA IN
ASSOCIATION WITH MID TO HIGH LEVEL MOISTURE. 00Z OBSERVED TAMPA AND
XMR SOUNDINGS REVEAL VERY DRY AIR FROM THE SURFACE TO 700 MB THAT
WILL LIKELY CAUSE ANY PRECIP TO EVAPORATE BEFORE REACHING THE
GROUND. REGARDING MIN TEMPS TONIGHT...A CHECK OF THE ACTUAL 00Z
TEMPS VS THE 18Z MAV GUIDANCE FCST FOR 00Z SHOWED TEMPS GENERALLY
3-6 DEG F ABOVE MAV GUIDANCE ACROSS EAST CENTRAL FLORIDA. DEWPOINTS
WERE ALSO A COUPLE OF DEGREES ABOVE GUIDANCE. WITH A STEADY STREAM
OF HIGH CLOUDS EXPECTED TO CONTINUE OVERNIGHT DO NOT BELIEVE WE WILL
REACH GUIDANCE LOWS. THE PREVIOUS FORECAST ALREADY ACCOUNTED FOR

.FIRE WEATHER...(PREVIOUS)...SFC/TRANSPORT WINDS TO VEER TO THE E/NE
SAT AFTN AS WEAK SFC RIDGE BUILDS OFF THE SERN SEABOARD.  THE

KEEP AFTN RH VALUES ABV CRITICAL LVLS FOR COASTAL AREAS.  HOWEVER...THE
REGIONAL PGRAD WILL BE QUITE WEAK WITH SFC/TRANSPORT WIND SPEEDS
ONLY EXPECTED TO BE ~5MPH.  THIS MAY NOT PROVIDE SUFFICIENT MOISTURE
ADVECTION TO KEEP AFTN RH VALUES FROM CRASHING OVER THE INTERIOR.
FIRE WX WATCH IN PLACE FOR THE INTERIOR COUNTIES.
