.DISCUSSION...

PACIFIC NORTHWEST AND DEPARTING LOW PRESSURE MOVING ITO THE
DESERT SOUTHWEST WILL REMAIN MOIST AND UNSTABLE ENOUGH FOR A
PASSING SHOWER OR THUNDERSTORM OVER THE BURN SITE THIS EVENING.
HIGH PRESSURE WILL BUILD OVER NORTHERN CALIFORNIA ON FRIDAY WITH
LIGHT NORTHEAST FLOW ALOFT CONTINUING. THERE WILL STILL BE A CHANCE
OF ISOLATED SHOWERS AND THUNDERSTORMS OVER THE NORTHERN SIERRA
NEVADA FRIDAY AFTERNOON AND EVENING...BUT THE FLOW WILL LIKELY BE
TOO LIGHT TO SPREAD ANY SHOWERS AND STORMS OVER THE BURN AREA.
