.DISCUSSION...

THIS WILL BE THE LAST DAY FOR THE EXTREMELY WARM...RECORD BREAKING
HEAT THAT HAS OCCURRED OVER THE PAST COUPLE OF WEEKS. WINDS WILL
BE LIGHT AND MAINLY TERRAIN DRIVEN TODAY...WITH SIMILAR
TEMPERATURES AND RELATIVE HUMIDITY OVER THE FIRE SITE TO WHAT
OCCURRED YESTERDAY.

A PACIFIC STORM SYSTEM WILL DIG INTO THE SOUTHWEST U.S. TODAY AND
MONDAY. THIS SYSTEM WILL BRING IN COOLER TEMPERATURES AND HIGHER
RELATIVE HUMIDITY MONDAY. IN ADDITION...WIDELY SCATTERED SHOWERS
AND POSSIBLY A THUNDERSTORM COULD AFFECT THE FIRE SITE MONDAY.
SOUTHERLY WINDS WILL ALSO PICK UP MONDAY. UNSETTLED WEATHER WITH
TEMPERATURES NEAR SEASONAL AVERAGES WILL PREVAIL THIS UPCOMING
WEEK. HOWEVER...SHOWERS ARE EXPECTED TO REMAIN SPOTTY AND LIGHT
WITH SLIM CHANCES OF RECEIVING A WETTING RAIN.

...THUNDERSTORMS IMPLY STRONG GUSTY AND ERRATIC WINDS...
