SERVICE.

.DISCUSSION...A WEAK UPPER LEVEL WEATHER DISTURBANCE WILL
INCREASE CLOUDS AND BRING A SLIGHT CHANCE OF LIGHT RAIN AFTER
MIDNIGHT NEAR THE FIRE. WITH THE INCREASED CLOUDS AND GIVEN THE
FIRES PROXIMITY TO THE RIVER...GOOD RECOVERIES ARE EXPECTED
TONIGHT. CLEARING IN THE MORNING WILL ALLOW FOR AN UNSTABLE
ATMOSPHERE TO INTERACT WITH THE UPPER LEVEL WEATHER SYSTEM AND
KEEP A CHANCE FOR SCATTERED SHOWERS AND THUNDERSTORMS NEAR THE
FIRE WEDNESDAY AFTERNOON. GIVEN THE VERY DRY LOW LEVELS...GUSTY
ERRATIC WINDS WILL BE THE MAIN IMPACT FROM NEARBY STORMS...AND
CHANCE OF WETTING RAINS WILL BE LOW UNLESS DIRECTLY UNDER A CELL.
