.DISCUSSION...
AN APPROACHING UPPER LEVEL TROUGH WILL BRING A SLIGHT CHANCE OF
THUNDERSTORMS AT THE FIRE...BUT MOST LIKELY ANY STORMS THAT FORM
SHOULD OCCUR EAST OF THE FIRE. WINDS ARE A BIT STRONGER THAN
YESTERDAY...WITH BOTH WEST AND EAST FACING SLOPES GETTING
WEST WINDS IN THE LATE AFTERNOON. WINDS TOMORROW WILL BE SIMILAR TO
TODAY. TEMPERATURES WILL TREND 5 TO 10 DEGREES COOLER DUE TO THE
TROUGH PASSAGE. THE AIR MASS
ALOFT WILL BE TOO DRY TO SUPPORT THUNDERSTORMS TOMORROW. THE TROUGH
SHOULD BRING SOME CLOUDS OVER THE WILDFIRE SITE TUESDAY MORNING.
TUESDAY NIGHT WILL FEATURE COLDER TEMPERATURES WITH MORE SLOPE
DRIVEN FLOWS.
