.DISCUSSION...
LITTLE CHANGE FROM THE HUFF BRIDGE FORECAST.

A HIGH PRESSURE RIDGE...EXTENDING FROM A HIGH PRESSURE CENTER IN THE
CENTRAL GULF OF MEXICO...WILL LAY NORTH OF THE AREA ACROSS CENTRAL
FLORIDA THIS MORNING. AS THE DAY PROGRESSES...THE RIDGE WILL SAG SOUTH
WITH THE HIGH PRESSURE CENTER MOVING OVER SOUTH FLORIDA TONIGHT. THIS
ENSURES CONTINUED DRY WEATHER AND NORTHERLY WINDS. SUSTAINED WINDS SHOULD
REMAIN BELOW 10 MPH AND COULD POSSIBLY BECOME A LITTLE BIT NORTHEAST IN
THE AFTERNOON HOURS WITH GUSTS 12 TO 15 MPH POSSIBLE. TONIGHT WINDS SHOULD
BECOME NORTH TO NORTHWEST AT 3 TO 5 MPH AT MOST THEN GO CALM LATER TONIGHT.

NO FOG IS EXPECTED.

DUE TO THE HIGH PRESSURE BUILDING OVER SOUTH FLORIDA...TRANSPORT WINDS ARE
RELATIVELY LOW AS WELL AS MIXING HEIGHT WHICH LEADS TO DISPERSION IN THE POOR
TO FAIR CATEGORY.
