DISCUSSION
THE PATTERN WILL SUPPORT SOUTHWEST WINDS THROUGH MUCH OF TODAY. AS
TEMPERATURES PEAK DURING THE EARLY TO MID AFTERNOON, MIXING HEIGHTS
MAY INCREASE TO NEAR 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 SOUTHWEST. THE
LOWEST RELATIVE HUMIDITY READINGS SHOULD OCCUR JUST PRIOR TO THE SEA
BREEZE LATE THIS AFTERNOON, WITH MIN VALUES AROUND 40 PERCENT. 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.
