.DISCUSSION...

STRONG HIGH PRESSURE WILL PERSIST OVER THE PROPOSED BURN SITE TODAY
AND SATURDAY. THIS WILL RESULT IN DRY AND STABLE CONDITIONS...BUT
ALSO POOR TO MODERATE SMOKE DISPERSAL. THE RIDGE WILL BREAKDOWN ON
SUNDAY AND MONDAY AND TRACK A COLD FRONT ACROSS THE BURN AREA. EXPECT
MUCH COOLER TEMPERATURES...INCREASED WINDS...BUT LITTLE IN THE WAY
OF RAIN. SPLIT FLOW IS POSSIBLE NEXT WEEK AS HIGH PRESSURE BUILDS INTO
BRITISH COLUMBIA AND A CLOSED LOW TAKES UP POSITION OVER CENTRAL
CALIFORNIA FOR MORE DRY CONDITIONS.
