WILL CONTINUE TO PUSH HIGH LEVEL CLOUDS OVER THE REGION AS IT
APPROACHES. SOUTHWEST WINDS WILL INCREASE INTO MONDAY FOLLOWED BY A
CHANCE OF PRECIPITATION MONDAY NIGHT INTO TUESDAY. AS A
RESULT...TEMPERATURES WILL COOL DOWN TO NORMAL VALUES BY MIDWEEK.

PUSHING MOISTURE ACROSS THE SOUTHWESTERN STATES. THE STRONG UPPER
LEVEL JET ASSOCIATED WITH THIS STORM WILL CONTINUE TO PUSH MOISTURE
OVER THE REGION. AT THE SAME TIME A NORTH-SOUTH SURFACE PRESSURE
GRADIENT IS SETTING UP TO BRING GUSTY SOUTH TO SOUTHWEST WINDS
OVERNIGHT TONIGHT. HIGH RESOLUTION MODELS STILL INDICATE DYNAMICS
FOR A WEAK TO MODERATE DOWNSLOPE EVENT IN THE LEE OF THE SIERRA AND
SPRING MOUNTAINS. HOWEVER...WIND GUSTS SHOULD REMAIN BELOW ADVISORY
CRITERIA IN BOTH LOCATIONS. THE TROUGH WILL BECOME MORE DEFINED AS
IT MOVES ON SHORE OVER THE NORTHERN CALIFORNIA AND OREGON BY MONDAY

DROPPING TEMPERATURES TO NORMAL VALUES FOR THE REMAINDER OF THE
SHORT TERM.

.LONG TERM...RIDGING TO BRIEFLY TAKE PLACE WEDNESDAY BEHIND THE
AFOREMENTIONED SHORTWAVE. SURFACE HIGH IS FORECAST TO BUILD IN OVER
NORTHERN NEVADA WEDNESDAY BRINGING AN INCREASING SURFACE PRESSURE
GRADIENT TO THE SOUTHERN HALF OF THE CWA. THIS WILL LEAD TO BREEZY
TO WINDY CONDITIONS DOWN THE COLORADO RIVER VALLEY WEDNESDAY AND
WEDNESDAY NIGHT. THE CURRENT RUN OF OF THE GFS IS SHOWING A
SHORTWAVE PUSHING INTO NORTHERN CALIFORNIA WEDNESDAY NIGHT AND
ACROSS THE EASTERN HALF OF THE CWA THURSDAY. BOTH THE ECMWF AND GEM
