WILL RISE INTO THE LOWER 80S ON SUNDAY...WITH A FEW LOCATIONS
REACHING THE MID 80S.

LOW-LEVEL WIND FLOW WILL BECOME LIGHT SOUTHERLY SUNDAY NIGHT INTO

BEFORE N FLOW RETURNS LATE TUESDAY.

THE UPPER RIDGE WILL SHIFT E EARLY NEXT WEEK AS A LOW PRESSURE
TROF DIGS OVER THE E PACIFIC. AN OMEGA BLOCK PATTERN WILL DEVELOP
OVER THE ROCKIES. THIS WILL BRING TEMPERATURES BACK DOWN TO MORE
SEASONAL LEVELS BY MID-WEEK. ENOUGH MOISTURE AND INSTABILITY WILL
BE IN PLACE TO BRING CHANCES FOR SHOWERS ACROSS MAINLY INLAND
PORTIONS OF THE AREA. HAVE CONTINUED TO INCLUDE ISOLATED
THUNDERSTORMS OVER THE INTERIOR AS WELL. A FEW STORMS MAY DEVELOP
TUESDAY AFTERNOON OVER THE EXTREME NE PORTION OF THE AREA WITH
ANY STORMS MOVING NE-E OUT OF THE AREA. CAPE AREAS ARE VERY
NARROW DURING THIS PERIOD. SLIGHTLY BETTER CHANCES FOR STORMS ARE
EXPECTED ON WEDNESDAY AFTERNOON WITH DEEPER AVAILABLE CAPE. A FEW
THUNDERSTORMS ARE AGAIN POSSIBLE ON THURSDAY AFTERNOON...AND SLOW
NE-SW STORM MOTION MAY ALLOW FOR A STRAY STORM TO DRIFT BACK
TOWARD THE COAST BEFORE WEAKENING. INSTABILITY WILL DECREASE LATE
IN THE WEEK...WITH DECREASING RAIN CHANCES AND NO THUNDERSTORMS
ANTICIPATED. /SEC
