FORECAST IS BASED ON REQUEST TIME OF 1121 PDT ON AUGUST 27.
IF CONDITIONS BECOME UNREPRESENTATIVE...CONTACT THE NATIONAL WEATHER
SERVICE.

.DISCUSSION...THE SMOKE INDUCED INVERSION SHOULD GRADUALLY ERODE
DURING THE AFTERNOON AS THE ATMOSPHERE IS EXPECTED TO BECOME MORE
UNSTABLE. HOWEVER THIS INSTABILITY SHOULD ALSO PRODUCE A SLIGHT
CHANCE OF AFTERNOON THUNDERSTORMS, CAPABLE OF PRODUCING GUSTY WINDS,
FREQUENT LIGHTNING BUT LITTLE, IF ANY RAINFALL. THE INVERSION SHOULD
ONCE AGAIN ESTABLISH OVERNIGHT TONIGHT, PREVENTING A PRODUCTIVE
RECOVERY FROM OCCURRING AND KEEPING TEMPERATURES AND HUMIDITY
READINGS NEAR, BUT PERHAPS A BIT WORSE THAN THOSE OBSERVED THIS
MORNING. STRONGER WINDS ARE FORECAST FOR TUESDAY AFTERNOON WHICH
WILL DRIVE RH'S DOWN INTO THE SINGLE DIGITS AT TIMES. TEMPERATURES
AND RH'S WILL BE VERY SIMILAR ACROSS THE ENTIRE SPAN OF THE FIRE'S
ELEVATIONS.
