.DISCUSSION...
VARIABLE WINDS AND SEA BREEZES WILL DOMINATE THE WEATHER TODAY. THE MAIN DIFFERENCE
BETWEEN TODAY AND YESTERDAY IS THAT THERE IS MORE MOISTURE AVAILABLE TODAY. THE COMBINATION
OF THIS MOISTURE WITH VERY COLD TEMPERATURES ALOFT FOR THIS TIME OF THE YEAR COULD
TRIGGER A FEW STRONG THUNDERSTORMS. THESE STORMS WILL PROBABLY START IN THE
INTERIOR AND THEN DRIFT EASTWARD AS THE AFTERNOON AND EVENING PROGRESSES.
THE RELATIVE HUMIDITY THIS AFTERNOON AT THE FIRE SITE COULD DROP BELOW
40 PERCENT BUT REMAIN ABOVE CRITICAL THRESHOLDS. THE LOW LEVEL WIND WILL ALSO
BECOME 5 TO 10 MPH. THIS WILL ALLOW THE DISPERSION TO BEGIN POOR TO FAIR BUT
BECOME GENERALLY GOOD BY EARLY IN THE AFTERNOON.
