FALL.

THIS EVENING THE UPPER PATTERN BEGINS TO CHANGE AS THE HIGH IS
PUSHED TO THE S AND E BY AN APPROACHING UPPER TROF. THERE WILL BE
ENOUGH LIFT ALONG WITH ONSHORE TRENDS TO BRING SOME MARINE CLOUDS TO
THE BEACHES OF THE CENTRAL COAST AND LA COAST. MAX TEMPS WILL FALL
BUT WILL BE ABOVE NORMAL. THE BIGGEST TEMP DROPS WILL BE NEAR THE
BEACHES WITH MUCH LESS COOLING INLAND.

MORE TROFING WILL BRING MORE MARINE LAYER STRATUS AND MORE COOLING

NORMAL VALUES WHILE THE INLAND AREAS WILL SEE MAX TEMPS 2 TO 3
DEGREES ABOVE NORMAL.

THERE WILL BE SUNDOWNERS EACH NIGHT ACROSS THE SBA SOUTH COAST.
