915 PM EST FRI JAN 21 2011

.DISCUSSION...

COLD FRONT CURRENTLY SITUATED ACROSS THE PENINSULA AROUND LAKE
OKEECHOBEE THIS EVENING. SFC ANALYSIS INDICATES A WEAK LOW PRESSURE
BEGINNING TO DEVELOP ALONG IT TO THE NORTH OF THE BAHAMAS AS THE
120KT JET OVERHEAD MOVES OFF TO THE NORTHEAST. HEAVIER RAIN HAS
MOVED OFFSHORE THIS EVENING...BUT A FEW LIGHT SHOWERS/DRIZZLE REMAIN
AS THE AREA REMAINS UNDER THE DIMINISHING INFLUENCE OF THE RIGHT
REAR QUAD OF THE JET AND A BAND OF 500 MB VORTICITY ROTATING
THROUGH. WILL LEAVE A SLIGHT CHANCE OF SHOWERS THROUGH THE NIGHT
ACROSS THE AREA TO ACCOUNT FOR ANY LINGERING ACTIVITY.

MAIN IMPACT OVERNIGHT WILL BE THE DEVELOPMENT OF FOG/STRATUS ACROSS
THE AREA. AS THE SFC RIDGE DRIFTS E...SUBSIDENCE OVER THE PENINSULA
WILL INCREASE...TRAPPING THE ABUNDANT LOW LVL MOISTURE BELOW IT
OVERNIGHT. EARLIER EXTENSIVE BLANKET OF STRATUS TO OUR NW HAS
DIMINISHED SOMEWHAT...BUT STILL EXPECT LOCAL DEVELOPMENT AS WELL AS
SOME ADVECTION INTO THE AREA. 15KT BOUNDARY LAYER WINDS WILL LIMIT
FOG COVERAGE TO PATCHY...WITH LOW STRATUS BEING THE MAIN CONCERN.

WITH LESS STRATUS CURRENTLY IN PLACE THAN EXPECTED RIGHT NOW...TEMPS
ARE DROPPING A LITTLE QUICKER...BUT AS WINDS WONT COME AROUND TO THE
N AND NW UNTIL LATER TONIGHT AS THE SFC LOW DEVELOPS AND PULLS
