DISCUSSION
A SEA BREEZE WILL REMAIN SOMEWHAT PINNED CLOSER TO THE COAST INTO LATE
AFTERNOON, PRIOR TO BRIEFLY NUDGING INLAND ACROSS THE BURN SITE APPROACHING
SUNSET. IF THE SEA BREEZE PASSES, SFC WINDS COULD TURN MORE SOUTHWEST FOR
ABOUT 1-2 HOURS. A COLD FRONT WILL THEN APPROACH FROM THE NORTH EARLY THIS
EVENING, LIKELY IMPACTING THE BURN SITE AROUND 8 PM. A FEW SHOWERS COULD ACCOMPANY
THE FRONT, BUT WILL REMAIN VERY ISOLATED IN NATURE. AN ISOLATED THUNDERSTORM
CAN NOT BE RULED OUT WITH THE FRONT PASSING, BUT CONDITIONS APPEAR LESS
SUPPORTIVE OF THIS ACTIVITY. WINDS TURN NORTHERLY ONCE THE FRONT PASSES,
GENERALLY RANGING BETWEEN 10-15 MPH INITIALLY, BUT THEN INCREASING TO
15-20 MPH BY AROUND 10 PM. GUSTY WINDS ARE LIKELY THROUGH THE REMAINDER OF
THE NIGHT ONCE THIS OCCURS AND COULD EVENTUALLY TIP MORE NORTHEAST IN DIRECTION
LATE. DRY HIGH PRESSURE IS FORECAST TO BUILD OVER THE REGION ON TUESDAY. NORTHEAST
WINDS BETWEEN 10 TO 15 MPH SHOULD ADVECT DEWPOINTS IN THE 30S ACROSS THE BURN
SITE ON TUESDAY. AS A RESULT, RELATIVE HUMIDITY VALUES ARE FORECAST TO
DROP INTO THE MID-UPPER 30S TUESDAY AFTERNOON.
