DRY AND MILD WEATHER WILL CONTINUE THROUGH THE
REMAINDER OF TODAY AS AN UPPER-LEVEL BLOCKING RIDGE REMAINS
ANCHORED OVER THE WEST COAST. FOR THE PLANTATION THIN 106 UNIT,
THE PRIMARY OPERATIONAL FOCUS IS ON THE STABLE BOUNDARY LAYER AND
LIGHT IN-STAND WINDS.
* TODAY (IGNITION WINDOW): EXPECT QUIET CONDITIONS WITH MOSTLY
SUNNY TO PARTLY CLOUDY SKIES. MIXING HEIGHTS WILL PEAK BETWEEN
2600-3500 FT AGL THIS AFTERNOON, PROVIDING ADEQUATE VERTICAL
ROOM FOR SMOKE LIFT. TRANSPORT WINDS REMAIN LIGHT FROM THE SOUTH
AT 6-8 MPH, WHICH IS BELOW THE IDEAL THRESHOLD (9-20 MPH) FOR
OPTIMAL HORIZONTAL DISPERSAL AND MAY RESULT IN LOCALIZED SMOKE
LINGERING WITHIN THE DRAINAGE. AT THE REQUEST OF THE USFS, EYE-
LEVEL WINDS ARE FORECAST TO BE VERY LIGHT AND VARIABLE AT 1-3
MPH WITHIN THE TIMBER STAND.
* TONIGHT & SATURDAY: HIGH-LEVEL MOISTURE WILL INCREASE, LEADING
TO MOSTLY CLOUDY SKIES. TRANSPORT WINDS ARE FORECAST TO
STRENGTHEN FROM THE SOUTHEAST TO 9-12 MPH BY SATURDAY MORNING,
WHICH WILL SIGNIFICANTLY IMPROVE SMOKE VENTILATION.
* CONTINGENCY: WHILE A WEAK COLD FRONT WILL APPROACH THE NORTHERN
PORTION OF THE AREA ON SUNDAY, WETTING RAIN (CWR) REMAINS AT 0%
FOR THIS LOCATION THROUGH THE CURRENT FORECAST PERIOD.
