SPOT FORECAST FOR RKS-EBMK...ROCK SPRINGS RUN SATE RESERVE
NATIONAL WEATHER SERVICE MELBOURNE FL
1007 AM EDT TUE MAY 20 2014

FORECAST IS BASED ON IGNITION TIME OF 1000 EDT ON MAY 20. 
IF CONDITIONS BECOME UNREPRESENTATIVE...CONTACT THE NATIONAL WEATHER
SERVICE.

.DISCUSSION...THERE WAS ALREADY A NORTHEAST WIND FLOW THIS MORNING...
AND BY EARLY-MID AFTERNOON THERE WILL BE AN ENHANCEMENT OF THIS FLOW
AS THE SEA BREEZE SHIFTS TO THE INTERIOR OF THE PENINSULA.  A RATHER
DRY AIR MASS WITH MIN RH VALUES 35-40 PERCENT WILL LEAD TO DEEP MIXING
DURING DAYTIME HEATING. SO WITH THE INCREASING WINDS/MIXING HEIGHTS...
DISPERSION VALUES WILL BECOME GENERALLY GOOD. A LATE NIGHT TEMPERATURE
INVERSION WILL FORM IN THE LOW LEVELS AND SURFACE WINDS WILL BECOME 
LIGHT. DRYNESS OF THE AIR MASS AND A WEAK BOUNDARY LAYER WIND FLOW 
SHOULD PRECLUDE DENSE FOG BUT THERE COULD BE PATCHY GROUND FOG.
