.DISCUSSION...

...STRONG WINDS AND LOW RELATIVE HUMIDITY LEVELS ARE POSSIBLE
THURSDAY AFTERNOON...

THIS AFTERNOON...LINGERING INSTABILITY WILL KEEP A SLIGHT CHANCE
FOR SHOWERS AND THUNDERSTORMS IN THE SURROUNDING MOUNTAINS.  A STRONG
DISTURBANCE WILL PUSH A DRY COLD FRONT OVER THE FIRE ON THURSDAY
RESULTING IN STRONG NORTHWEST WINDS AND LOW RELATIVE HUMIDITY VALUES.
THIS WILL LEAD TO MARGINAL RED-FLAG CONDITIONS FOR A SHORT PERIOD.
RELATIVE HUMIDITIES WILL INCREASE AS THE STRONGEST WINDS DESCEND ON
THE FIRE THURSDAY AFTERNOON.  A HOT AND DRY PERIOD IS EXPECTED FRIDAY
THROUGH THE BEGINNING OF THE WEEK WITH A SMALL THREAT FOR THUNDERSTORMS
BY THE MIDDLE OF NEXT WEEK.
