AREA FORECAST DISCUSSION

319 PM PDT WED JUN 12 2013

.SYNOPSIS...A DRY SOUTHWEST FLOW WILL PERSIST OVER THE CENTRAL
CALIFORNIA INTERIOR FOR THE NEXT SEVERAL DAYS. SEASONAL TEMPERATURES
AND DRY WEATHER WILL PREVAIL.

&&

.DISCUSSION...
AN UPPER LEVEL CLOSED LOW OFF OVER THE PACIFIC NORTHWEST CONTINUES
TO REMAIN IN PLACE BRINGING SHORTWAVE ENERGY IMPULSES AROUND THE
SOUTHERN PERIPHERY OF THE UPPER LOW.

LATEST WATER VAPOR IMAGERY SHOWS THE LATEST MID LEVEL SHORTWAVE
TROUGH CURRENTLY CENTERED OVER THE PACIFIC NEAR 34N/120W AND
MOVING EASTWARD TOWARDS THE SOUTHERN CENTRAL CALIFORNIA COAST.
AHEAD OF THIS DRY SHORTWAVE THE MARINE LAYER HAS BEEN THICKENING
THROUGH THE MORNING AND AFTERNOON HOURS AND ACCORDING TO FORT ORD
PROFILER DATA IS CURRENTLY AROUND 1900 FEET. AS THE TROUGH GETS
CLOSER THE MARINE LAYER WILL BEGIN TO SPILL THROUGH THE PACHECO
PASS AND SUNFLOWER VALLEY. SFO-LAS P-GRADS WILL HOVER AROUND 10 MB
THIS EVENING. WINDS ALONG THE WEST SIDE OF THE SAN JOAQUIN VALLEY
WILL APPROACH 35 TO 40 MPH FOR A SHORT TIME AND COULD KICK UP
SOME PATCHY DUST...ESPECIALLY NEAR THE AFOREMENTIONED PASSES. WINDS
WILL BE GUSTY IN THE KERN COUNTY DESERT AREAS AS WELL THIS
EVENING. AT THIS TIME WIND ADVISORIES DO NOT LOOK NECESSARY AS
THE DURATION OF THE STRONGEST WINDS WILL BE SHORT-LIVED. PRESSURE
GRADIENTS ARE PROGGED TO INCREASE TOMORROW AFTERNOON AND IS LIKELY
A HARBINGER OF ANOTHER MARINE PUSH TOMORROW.

THIS DRY ONSHORE FLOW WILL CONTINUE INTO EARLY NEXT WEEK AND WILL KEEP
TEMPERATURES NEAR NORMAL LEVELS. ALTHOUGH...THURSDAY TEMPERATURES WILL
BE KEPT SLIGHTLY BELOW NORMS FOR MOST OF THE AREA AS THE COOLER
DRIER MARINE AIRMASS SETTLES INTO THE SAN JOAQUIN VALLEY.
TEMPERATURES WILL THEN AGAIN GRADUALLY INCREASE UNTIL ANOTHER
MARINE PUSH ON SUNDAY KNOCKS TEMPERATURES BACK BELOW NORMAL LEVELS
ONCE AGAIN. THIS PATTERN LOOKS TO CONTINUE AT LEAST THROUGH NEXT
THURSDAY.
