.DISCUSSION...GUSTY SOUTHERLY WINDS ACROSS CLARK...LINCOLN AND 
MOHAVE COUNTIES ASSOCIATED WITH EXITING SHORTWAVE WILL LINGER INTO 
THE EARLY EVENING BEFORE DISSIPATING OVERNIGHT. SKIES WILL BE MOSTLY 
CLEAR UNDER PASSING WAVES OF HIGH CLOUDS.

FROM SOUTHERN CALIFORNIA EASTWARD TO TEXAS. WINDS WILL BE LIGHT 
WEDNESDAY AND THURSDAY BUT WILL START TO INCREASE IN THE FAR 
NORTHWEST (INYO/ESMERALDA COUNTIES) DUE TO AN APPROACHING TROUGH.

FROM SATURDAY ONWARD, THE ECMWF HAS COME MORE IN LINE WITH THE GFS.

MODEL FLIPS BACK TO A DEEPER TROUGH PASSAGE OVER THE WEEKEND. MOST 
AREAS WILL EXPERIENCE GUSTY SOUTHWEST WINDS SATURDAY. LOCALIZED 
DOWNSLOPING POSSIBLE IN THE LEE OF THE SOUTHERN SIERRA AND SPRING 
MOUNTAINS SATURDAY NIGHT INTO SUNDAY MORNING. WINDS LOOK TO STAY 
SUB-ADVISORY THROUGHOUT THE EVENT. WINDS SHOULD SHIFT TO THE 
NORTHWEST SUNDAY FOLLOWING THE PASSAGE OF A COLD FRONT. SATURDAY MAY 
BE THE WARMEST DAY FOLLOWED BY ABOUT 10 DEGREES OF COOLING SUNDAY. 
THAT 10 DEGREE DROP IN TEMPERATURES WILL BRING READINGS BACK DOWN TO 
NORMAL.
