.DISCUSSION...TUESDAY NIGHT THROUGH FRIDAY. RIDGE ALOFT SUPPORTS
CLEAR SKIES THROUGH MUCH OF WEDNESDAY. THEN, THE UPPER LOW THAT IS

SHOWERS AND A SLIGHT CHANCE OF AFTERNOON AND EVENING THUNDERSTORMS
FROM WEDNESDAY NIGHT THROUGH FRIDAY. AFTERNOON TEMPERATURES COOL A
BIT ON THURSDAY AND FRIDAY DUE TO INCREASED CLOUD COVER.

WEDNESDAY, BUT UNTIL THEN CLEAR WITH LIGHT WINDS.

.LONG TERM...SATURDAY THROUGH TUESDAY. AN UPPER-LEVEL TROUGH OFF
THE PACIFIC WILL MOVE ACROSS THE AREA SATURDAY THROUGH TUESDAY.

PRECIP THROUGHOUT THE PERIOD. TEMPERATURES WILL COOL DRAMATICALLY,
WITH HIGHS ONLY IN THE 50S IN THE LOWER VALLEYS, AND IN THE 40S IN
THE MOUNTAINS BY EARLY NEXT WEEK. SNOW LEVELS WILL LOWER FROM
