SYNOPSIS
THE WEATHER WILL CONTINUE TO BE FAIRLY BENIGN AND UNCHANGED FROM
DAY TO DAY THIS WEEK WITH MARINE LAYER CLOUDS MAKING AN APPEARANCE
EACH EVENING AND MORNING ALONG THE COAST INTO FAR WESTERN
VALLEYS. SLIGHT COOLING MAY OCCUR BY NEXT WEEK AS A LOW PRESSURE

..NEW AVIATION DISCUSSION FOR THE 06Z TAF PACKAGE
ITS A BENIGN, WARM DAY OUT THERE TODAY. TEMPERATURES THIS
AFTERNOON AWAY FROM THE IMMEDIATE COAST ARE ANYWHERE FROM 1 TO 12
DEGREES WARMER THAN THIS TIME YESTERDAY, WITH 60S TO MID 70S ALONG
THE COAST, 70S TO LOW 80S INLAND AND IN THE MOUNTAINS, AND 90S TO
100 IN THE LOW DESERTS. WE'VE SEEN NEARLY COMPLETELY CLEAR SKIES
TODAY FOLLOWING THE BURN OFF OF MARINE LAYER LOW CLOUDS LATE THIS
MORNING.
TODAY IS PRETTY REPRESENTATIVE OF WHAT THE REST OF THE WEEK WILL
LOOK LIKE. TEMPERATURES WILL FLUCTUATE ONLY A FEW DEGREES UP OR
DOWN EACH DAY THROUGH THURSDAY, ALBEIT WITH SLIGHT WARMING IN THE
DESERTS THROUGH WEDNESDAY. MARINE LAYER LOW CLOUDS WILL RETURN TO
THE COASTS AND WESTERN VALLEYS EACH EVENING THROUGH MID TO LATE
MORNING, FOLLOWED BY MOSTLY CLEAR SKIES WITH THE OCCASIONAL
CUMULUS OVER THE MOUNTAINS OR UPPER LEVEL CLOUDS PASSING OVER.
AFTERNOON BREEZES WILL BE MILD AND SEASONABLY TYPICAL.
BROAD TROUGHING OVER THE NORTHWEST U.S. LATE WEEK INTO THE
FOLLOWING WEEK WILL LIKELY LEAD TO AT LEAST A SLIGHT COOLING
TREND LOCALLY. THE EXTENT OF THE COOLING WILL DEPEND ON TROUGH
POSITION, WHICH STILL DIFFERS BETWEEN MODELS, ESPECIALLY HEADING
INTO THE FOLLOWING WEEK.
