OVER LAND WILL DEFINE THE NEXT SEVERAL DAYS.
PERSISTENT FORECAST IN PLAY THROUGH EARLY NEXT WEEK COURTESY OF
BERMUDA HIGH PRESSURE PROVIDING CONTINUED ADVECTION OF WARM,
MOIST AIR. INLAND TEMPS IN THE LOW 80S INTO THE MIDDLE OF NEXT
WEEK, WITH AFTERNOON SEA BREEZE KEEPING THE IMMEDIATE COASTLINE
IN THE LOW TO MID 70S. LOW TEMPS EACH NIGHT AROUND 60F. THESE
TEMPERATURES ARE MORE REPRESENTATIVE OF EARLY MAY VERSUS EARLY
MARCH. THE NEXT COUPLE OF DAYS WILL REMAIN DRY DUE TO MID LEVEL
RIDGING ALOFT. AFTERNOON THUNDERSTORMS WILL BE POSSIBLE SUNDAY
THROUGH TUESDAY, DUE TO DAYTIME HEATING AND SEA BREEZE, AS THE
SUBSIDENCE ALOFT WEAKENS.
DENSE FOG WILL BE POSSIBLE EACH NIGHT AND MORNING INTO EARLY
NEXT WEEK DUE TO DEWPOINTS IN THE 60S AND HIGH PRESSURE KEEPING
WINDS RELATIVELY LIGHT. HIGH DEWPOINTS WILL ALSO CONTRIBUTE TO
