SEASONAL TEMPERATURES WILL CONTINUE ONE MORE DAY AS STRONG NW

BIT OF A GRADIENT AS THE RIDGE WILL IMPACT VALLEY WINDS NEAR MCE

NORMAL THROUGH TUESDAY BEFORE A DIGGING TROUGH OF LOW PRESSURE
WILL MOVE INTO THE REGION AND COOL THINGS DOWN AGAIN LATE IN THE

INTO THE KERN DESERT AND BELOW THE PASSES. THIS SYSTEM WILL BE
SLOW TO MOVE OUT AS THE MAIN CENTER OF LOW PRESSURE WILL REMAIN
OVER THE PAC NW AS AN OMEGA BLOCKING PATTERN SETS UP OVER THE US

ONSHORE FLOW OVER THE REGION WITH SEASONAL TEMPERATURES AND DRY
CONDITIONS INTO THE HOLIDAY WEEKEND.
