Strong Wind in California, May 10, 2004

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HANFORD CA
300 AM PDT MON MAY 10 2004

.SHORT TERM...FOR THE CENTRAL CALIFORNIA INTERIOR...A CHANGE IN THE
WEATHER IS FINALLY IN-STORE FOR THE CWFA AS SEEN ON WATER VAPOR
IMAGERY ALONG WITH RUC ANALYSIS. THE UPPER LOW THAT REMAINED
SOMEWHAT STATIONARY OUT OVER THE EASTERN PACIFIC IS NOW DROPPING
INTO NORTHERN CALIFORNIA THIS MORNING. TROF AXIS...BASED ON
SATELLITE AND RUC ANALYSIS...IS CURRENTLY ALONG THE PACIFIC
NORTHWEST COAST LINE AND PROGGED TO PUSH FURTHER INLAND DURING THE
MORNING HOURS. MODEL TIMING HAS THE BULK OF THE TROF ENERGY OVER THE
DISTRICT AROUND 500 PM THIS AFTERNOON. THIS TIMING AGREES WITH
FORECAST PACKAGE OF SHOWING MUCH OF THE WEATHER ACTIVITIES OCCURRING
DURING THE AFTERNOON HOURS. WILL KEEP A MENTION OF SHOWERS NEAR
YOSEMITE THIS AFTERNOON AND GO AHEAD AND ISSUE A WIND ADVISORY FOR
THE KERN COUNTY MOUNTAINS AND DESERTS ALSO FOR THIS AFTERNOON.
WHILE 700MB WINDS ARE NOT PROGGED BY THE MODELS TO RISE ABOVE 30KTS
...SURFACE PRESSURE GRADIENTS WILL TIGHTEN ABOVE 12MB FROM SFO TO
LAS. MODELS SHOW A GRADIENT OF BETWEEN 14MB TO 16MB AT 500PM. IN
ADDITION...MODELS ARE SHOWING MODERATE SUBSIDENCE TO HELP SUPPORT
THE STRONG WINDS OVER KERN COUNTY. FURTHERMORE...MODELS SHOW A GOOD
POOL OF COLD AIR DROPPING INTO THE REGION WITH SOME INFLUENCES FELT
OVER THE DISTRICT. TEMP/S AT THE 850MB LEVEL DROP SOME 2-3 DEG-C IN
THE 24 HOUR PERIOD ENDING AT 5PM THIS AFTERNOON. THIS TRANSLATES IN
A COOLING TREND FOR TODAY WITH MAX TEMP/S DOWN SOME 3-5 DEG-F.

THIS EVENING...THE DISTRICT WILL BE BETWEEN TROF/S AS A SECONDARY
TROF DROPS IN BEHIND THE FIRST. MODELS SHOW GOOD CONSENSUS ON TIMING
THE SECONDARY TROF OVER THE SIERRA NEVADA BY 5PM ON TUESDAY. YET...
THIS TROF IS ASSOCIATED WITH LESS MOISTURE AS THE TRAJECTORY IS MORE
OF AN INSIDE SLIDER. THEREFORE...WILL SEE WINDS PICK UP AGAIN ON
TUESDAY AFTERNOON WITH AN EVEN LESSER CHANCE OF POSSIBLE PRECIP.
TEMPERATURE WILL CONTINUE ITS COOLING TREND AS THE AIRMASS OVER THE
DISTRICT WILL BE INFLUENCED BY THE CYCLONIC FLOW OVER THE REGION.
WEDNESDAY WILL SEE THE REGION BEGIN RECOVERING FROM THIS
DISTURBANCE. MODELS SHOW SLIGHT 500MB HEIGHT RISES AS THE LONGER
WAVE TROF PATTERN BEGINS TO SHIFT EAST OF THE DISTRICT. THAT THIS
TIME...WILL START A WARMING TREND AFTER HAVING TODAY AND TUESDAY ON
THE COOL SIDE.

.LONG TERM...FOR THURSDAY THROUGH SUNDAY...MEDIUM RANGE MODELS IN
GOOD AGREEMENT THROUGH THURSDAY...THEN START TO DIVERGE FRIDAY OVER
THE THE EASTERN PACIFIC. AN UPPER LEVEL TROUGH WILL MOVE EASTWARD
INTO THE ROCKIES ALLOWING HEIGHTS AND THICKNESSES TO RECOVER OVER
THE WEST COAST THURSDAY AND FRIDAY. MEANWHILE AN UPPER RIDGE ALONG
THE EAST PACIFIC WILL AMPLIFY AND BUILD INTO THE CANADIAN/U.S. WEST
COASTS FRIDAY. THIS WILL ALLOW TEMPERATURES TO RECOVER TO NEAR
SEASONAL NORMALS. MODELS MAINTAIN DRY CONDITIONS ACROSS CENTRAL
CALIFORNIA BUT DIVERGE AS TO THE AMOUNT OF WARMING THAT WILL TAKE
PLACE OVER THE WEEKEND. THE EURO SHOWS A STRONGER RIDGE ALONG THE
WEST COAST AND A BETTER WARMING TREND. HOWEVER THE LATEST CANADIAN
MODEL IS TRENDING TOWARDS THE COOLER GFS SOLUTION WHICH PROGS COOLER
WSW OVER CENTRAL CALIFORNIA AS AN UPPER LEVEL LOW REACHES THE
PACIFIC NORTHWEST COAST SATURDAY. THE LOW SHOULD SUPPRESS HEIGHT
RISES AND KEEP TEMPERATURES FROM RISING MUCH ABOVE SEASONAL NORMALS.

.HNX WATCHES/WARNINGS/ADVISORIES...WIND ADVISORY FOR THE KERN COUNTY
     MOUNTAINS AND DESERTS TODAY THROUGH 800 PM PDT.
