AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MELBOURNE FL
955 AM EDT SUN MAR 23 2008
.DISCUSSION...
SFC OBSERVATIONS INDICATE WEAK SFC WAVE OVER SOUTH FL AND A COLD
FRONT ACROSS N FL. IN BETWEEN ACROSS CENT FL...THERE EXISTS VERY
LIGHT PRESSURE GRADIENT WITH OVC CONDS AND PATCHY LIGHT SHOWERS
AND SPRINKLES. EXPECT SFC WAVE TO CONTINUE EAST OF THE AREA TODAY
WITH WINDS TURNING NE ACROSS THE FA THIS AFTN. SOME DRIER AIR WILL
FILTER INTO NORTHERN SECTIONS AND DECREASE THE CLOUDINESS BUT WILL
STILL CALL IT PARTLY CLOUDY. UPDATED FCST EARLIER TO ACCOUNT FOR
THE SPRINKLES AND LIGHT SHOWERS BUT MEASURABLE RAIN APPEARS
UNLIKELY. GFS CONTINUES TO INSIST THERE WILL BE A PERIOD OF
MEASURABLE RAIN ACROSS NORTHERN SECTIONS THIS AFTN...PRESUMABLY IN
ASSOC WITH INSTABILITY CAUSED BY SFC HEATING AS CLOUDS BREAK UP
AND COLD FRONT SLOWLY DROPS SOUTHWARD. THINK THERE IS A BETTER
CHANCE ACROSS SOUTHERN SECTIONS.

.AVIATION...VFR CIGS SHOULD HOLD ACROSS THE SOUTH (MLB/VRB/FPR)
BUT WILL GIVE WAY TO OCNL SCT CONDS ACROSS NORTHERN SECTIONS
(LEE/DAB/SFB/MCO).

.MARINE...WINDS/SEAS WILL NOT BE A PROBLEM TODAY AS WEAK SURFACE
TROUGH MOVES ACROSS THE WATERS. PRIMARY CONTRIBUTION TO WAVE HGT

ENTER THE NORTHERN WATERS AND OVERSPREAD ENTIRE MARINE AREA MONDAY.
SMALL CRAFT ADVISORIES WILL BE RAISED WITH THE AFTERNOON PACKAGE.
