AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
325 PM PDT WED JUL 11 2001

DEEP MOIST CONVECTION CONTINUES TO FIRE ACROSS HIGHER TERRAIN OF
NORCAL AIDED BY FAIRLY STRONG SHORT WAVE. THIS WAVE IS FORECAST TO
MOVE TO OUR NORTH BY 06Z WITH NVA RELATED SUBSIDENCE PUTTING AN
END TO THE CONVECTION THEREAFTER. MODELS AGREE ON BETTER SOUTHWEST
FLOW DEVELOPING ALOFT FOR THURSDAY THROUGH THE WEEKEND...BUT
CONTINUE TO SHOW WEAK SHORT WAVES CIRCULATING AROUND THE OFFSHORE
TROUGH. MODELS ALSO AGREE ON A SMATTERING OF CONVECTIVE PRECIP
EACH AFTERNOON ACROSS THE CA/OR BORDER REGION THROUGH THE UPCOMING
WEEKEND. SHORT WAVES ARE EXTREMELY DIFFICULT TO TIME IN THIS TYPE OF
PATTERN...AND DESPITE DRYING INDICATED ON THE MODELS...IT DOESN/T
TAKE MUCH MOISTURE TO TRIGGER ELEVATED CONVECTION OVER THE
MOUNTAINS. SO WILL KEEP A SLIGHT CHANCE OF AFTERNOON/EVENING TSTMS
ACROSS OUR NORTHERN MOUNTAINS EACH DAY THROUGH THE WEEKEND.

MARINE LAYER WILL ALSO OFFER A FEW CHALLENGES FOR OUR TEMPERATURE
FORECAST. MARINE LAYER HAS BECOMINE SOMEWHAT MIXED OFFSHORE THIS
AFTERNOON AS A RESULT OF THE SHORT WAVE PASSAGE. HOWEVER...IT IS
EXPECTED TO QUICKLY REBUILD OVERNIGHT AS SUBSIDENCE RETURNS. IN
FACT...THE ETA VIEWED WITH BUFKIT EVEN SHOWS A MINOR STRATUS
INTRUSION INTO THE SOUTHERN SAC VALLEY BY MORNING. DESPITE GRADUALLY
BUILDING HEIGHTS INTO THE WEEKEND...ANY WARMUP WILL BE TEMPERED BY
CONTINUED ONSHORE FLOW AND RELATIVELY DEEP MARINE LAYER.

IN THE EXTENDED...MODELS CONTINUE TO SHOW TROFFINESS OVER THE WEST
COAST FOR DAYS 3-7. MRF LOOKS TO BE THE MOST AGGRESSIVE ON DROPPING
UPPER LOW FROM THE PACIFIC NORTHWEST INTO EXTREME NORCAL. EVEN THE
NEW AVN IS LESS AGGRESSIVE THAN THE MRF...MAKING THE MRF SOLUTION A
LITTLE SUSPECT. GOING WITH MORE OF A MODEL CONSENSUS...LOOKS LIKE
DRY WEATHER FOR MOST LOCALES WITH A GRADUAL COOLING TREND AS WE HEAD
INTO EARLY NEXT WEEK. THE ONLY EXCEPTION MIGHT BE ACROSS OUR FAR
NORTHERN MOUNTAINS WHERE THERE MAY BE ENOUGH CYCLONIC CONVERGENCE
OFFERED BY THE AFOREMENTIONED TROUGH/UPPER LOW TO GENERATE A FEW
AFTERNOON SHOWERS EACH DAY.
