NATIONAL WEATHER SERVICE SALT LAKE CITY UT
619 PM MDT TUE OCT 19 2010

.DISCUSSION...A LOW PRESSURE SYSTEM OVER FAR SOUTHERN CALIFORNIA
WILL TRACK EAST-NORTHEAST ACROSS ARIZONA THROUGH THURSDAY. AS IT
DOES SO...MOISTURE WILL SPREAD NORTH INTO SOUTHERN UTAH BEGINNING
LATE TONIGHT. THIS COULD RESULT IN SHOWERS BEGINNING NEAR THE BURN
SITE BY 0800...WITH AREAL COVERAGE INCREASING THROUGH THE AFTERNOON.
THUNDERSTORMS WILL LIKELY HOLD OFF UNTIL 1200-1300...ALTHOUGH IT IS
IMPOSSIBLE TO RULE OUT AN ISOLATED MORNING THUNDERSTORM. AMPLE
MOISTURE WILL REMAIN OVER THE AREA THROUGH THURSDAY...CAUSING
SHOWERS/THUNDERSTORMS TO CONTINUE THROUGH THAT TIME. EXPECT A TREND
OF COOLER TEMPERATURES AND HIGHER HUMIDITIES THE NEXT COUPLE OF
DAYS. SNOW LEVELS WILL GENERALLY REMAIN ABOVE 9500 FT...BUT THE
HEAVIER SHOWERS MAY DRAG THAT DOWN CLOSER TO 8500-9000 FT. UNSETTLED
WEATHER THEN LOOKS TO CONTINUE INTO THE WEEKEND AS ANOTHER WEAK
SYSTEM IMPACTS THE AREA.
