QUITE WARM AND DRY. WINDS MAY BE GUSTING TO 25 MPH BY TUESDAY
EVENING. ON WEDNESDAY THE TROUGH MOVES ACROSS THE FORECAST AREA.
THOUGH THE THREAT OF WETTING RAIN IS LOW...THE RELATIVE HUMIDITY

WEDNESDAY NIGHT OVER THE BURN AREA. STRONG DRYING TREND THURSDAY AND
FRIDAY AS A MODERATE OFFSHORE WIND PATTERN SETS UP. THIS WILL BE
