.DISCUSSION...
UPPER LEVEL PATTERN REMAINS FAIRLY CONSISTENT...WITH A TROUGH OFF
THE COAST AND A RIDGE OVER THE CENTRAL U.S. AN UPPER LOW PASSING
THROUGH BRITISH COLUMBIA IS FLATTENING THE RIDGE IN THE WEST WITH
SLIGHTLY LOWER TEMPERATURES EXPECTED THROUGH THE WEEKEND. CURRENT
TEMPERATURES ARE 1 TO 3 DEGREES LOWER THAN THIS TIME YESTERDAY.
HIGHS TODAY WILL BE AROUND 90 IN THE VALLEY AND MAYBE A BIT LITTLE
LOWER TOMORROW. GUSTY WINDS WILL DEVELOP OVER HIGHER MOUNTAINS THIS
AFTERNOON AS PRESSURE GRADIENT INCREASES AND 70 KT JET MOVES OVER
NORTHERN CALIFORNIA...AND INCREASE FURTHER SUNDAY AFTERNOON/EVENING.
MINIMUM RELATIVE HUMIDITY LEVELS FOR SUNDAY AFTERNOON CONTINUE TO
LOOK QUITE LOW FOR THE BURNEY BASIN...AND SHOULD MEET CRITERIA FOR A
RED FLAG WARNING. CURRENT PLAN IS FOR THE SUNDAY AFTERNOON/EVENING

THROUGH MIDWEEK...BUT RELATIVE HUMIDITY LEVELS SHOULD INCREASE WITH
SOUTHWESTERLY FLOW. TEMPERATURES WARMING TO AROUND AVERAGE LEVELS
