SPOT FORECAST FOR JUNO DUNES 5...PALM BEACH COUNTY ERM
NATIONAL WEATHER SERVICE MIAMI FL
558 AM EDT THU MAR 25 2010

FORECAST IS BASED ON IGNITION TIME OF 1000 EDT ON MARCH 25.
IF CONDITIONS BECOME UNREPRESENTATIVE, CONTACT THE NATIONAL WEATHER
SERVICE.

.DISCUSSION...HIGH PRESSURE RIDGING OVER THE WESTERN ATLANTIC WILL
CONTINUE MOVING EAST. AS THIS HAPPENS, WINDS WILL BE SOUTHEAST ALL
AREAS TODAY AND WILL BECOME SOUTH TONIGHT WITH A SLIGHT INCREASE
IN WINDS IN THE MIXING LAYER POSSIBLE. CLOUDS WILL BEGIN TO REALLY
INCREASE AND THICKEN TONIGHT...AS WINDS SHIFT TO THE SOUTH AND DRAW
MORE MOISTURE ACROSS THE AREA. SOME SHOWERS WILL BE POSSIBLE TONIGHT
AREA WIDE AS THIS HAPPENS BUT MOST WILL BE LIGHT. LATEST COMPUTER
MODEL FORECASTS INDICATE THAT THESE SHOWERS WILL BE ISOLATED ENOUGH
TO POTENTIALLY LEAD TO PATCHY FOG FORMATION TONIGHT ESPECIALLY OVER
INTERIOR AREAS. A COLD FRONT WILL APPROACH THE REGION ON FRIDAY LEADING
TO INCREASED CHANCES FOR SHOWERS AND THUNDERSTORMS AS SOUTHWEST TO WEST
TRANSPORT WINDS AND DISPERSION INDICES INCREASE. DISPERSION LEVELS TODAY
WILL BE FAIR EXCEPT GENERALLY GOOD NORTH INTERIOR, GOOD TO VERY GOOD
TONIGHT AND VERY GOOD ALL AREAS FRIDAY.

.NOTE...AMENDED THE FIRE WEATHER FORECAST WITH NEWER MODEL GUIDANCE
AND IT GAVE ME SLIGHTLY HIGHER TRANSPORT WINDS FOR A MAX LDSI OF 42.
