DISCUSSION
THE PATTERN WILL SUPPORT SOUTHWEST WINDS THROUGH MUCH OF TODAY. AS
TEMPERATURES PEAK DURING THE EARLY TO MID AFTERNOON, MIXING HEIGHTS
MAY PEAK WITHIN 4 TO 5 KFT, YIELDING SOME GUSTS AROUND 20 MPH
FROM THE SW UNTIL SUNSET. A WEAK SEA BREEZE MAY CROSS THE BURN SITE
LATE THIS AFTERNOON, WITH A SLIGHT WIND SHIFT FROM THE SSW. THE
LOWEST RELATIVE HUMIDITY READINGS SHOULD OCCUR JUST PRIOR TO THE SEA
BREEZE LATE THIS AFTERNOON, WITH MIN VALUES BETWEEN 40 TO 45%. VERY
LOW RISK FOR FOG TONIGHT. HIGH PRESSURE WILL PROVIDE ANOTHER DAY OF
SOUTHWEST WINDS. A BACKDOOR COLD FRONT IS TIMED TO PUSH ACROSS BURN
SITE MONDAY EVENING, ACCOMPANIED BY SCATTERED SHOWER AND
THUNDERSTORMS. GUSTY NORTHEAST WINDS SHOULD DEVELOP MONDAY NIGHT,
REMAINING THROUGH TUESDAY.
