AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SACRAMENTO CA 940 PM PST THU FEB 15 2007 .UPDATE DISCUSSION... UPR RIDGE STILL OUT OVER 130W TRANSLATING DOWN TO SFC RIDGE OVER NRN CAL AND EAST INTO THE GREAT BASIN. WATER VAPOR METSAT IMAGERY SHOWS THE PFJ DEEPENING UPR LVL TROUGH NEAR 160W. THE TROUGH IS BECOMING MORE AMPLIFIED AS THE ASSOCIATED BAROCLINIC LEAF IS BEGINNING TO TAKE ON A CLASSIC COMMA SHAPE. INITIALLY NORCAL WILL HAVE LESS UPR CLOUDINESS FRIDAY AS THE TROUGH/RIDGE COUPLET AMPLIFIES. THEN THE STEERING FLOW WILL SWITCH FROM NORTHWEST TO SOUTHWEST AS THE UPR LVL TROUGH APPROACHES. THE 00Z GFS AND NAM BOTH SPLIT THE TROUGH NEAR 40N AS IT MAKES LANDFALL SUNDAY MORNING...OF COURSE PRECIP WILL START OVER THE NRN MOUNTAINS OVERNIGHT SATURDAY INTO SUNDAY. GFS AND ETA BUFKIT PRECIPITABLE WATER AMOUNTS ARE LESS THAN 0.6 FOR THE SAC VALLEY AND LESS THAN 0.3 FOR BLUE CANYON ON SUNDAY. BUFKIT ONLY WENT OUT TO SUNDAY AFTERNOON AND THE UPR TROUGH DOES NOT PASS THROUGH NORCAL UNTIL OVERNIGHT SUNDAY. WE SHOULD EXPECT GREATER PRECIP AMOUNTS OVER THE MOUNTAINS THAN IN THE VALLEY...ESPECIALLY WITH THE PERPENDICULAR OROGRAPHIC WIND COMPONENT. LOOK FOR STRONG NORTHEASTERLY SFC FLOW OVER THE SIERRA SUNDAY INTO MONDAY AS THE TROUGH PASSES. RIDGE BUILDS IN LATE MONDAY INTO TUESDAY UNTIL... WEDNESDAY A MORE VIGOROUS STORM ADVECTS INTO NORCAL WITH STRONGER UPPER DYNAMICS...120KT JET MAX AND COLDER AIR ALOFT. PRECIP AMOUNTS CAN VARY WIDELY A WEEK OUT. BUT GFS SHOWS STRONG PRECIP AMOUNTS OVER THE CWA...ESPECIALLY OVER THE MOUNTAINOUS TERRAIN. SNOW AMOUNTS WILL BE MORE OF A FACTOR AS THE SNOW LEVELS WILL DROP TO 4000 FT IN THE SIERRA...POSSIBLY LOWER...ESPECIALLY UP NORTH. JCLAPP .PREVIOUS DISCUSSION 300 PM PST... RIDGE OF HIGH PRESSURE OVER THE EASTERN PACIFIC WILL DOMINATE THE WEATHER PATTERN THE NEXT FEW DAYS AS IT SLOWLY MOVES EAST. RIDGE SHOULD GIVE US ABOVE SEASONAL NORMAL MAXIMUMS FOR THE NEXT COUPLE OF DAYS. AS THIS RIDGE MOVES EAST INTO NEVADA ON SUNDAY THE SOUTH END OF A LOW PRESSURE SYSTEM THAT IS MOVING INTO BRITISH COLUMBIA WILL BRING RAIN, WITH SNOW ABOVE 4,500 TO 5,500 FEET, TO INTERIOR NORTHERN CALIFORNIA. CURRENT QUANTITATIVE PRECIPITATION ESTIMATES ARE LIGHT TO MODERATE, ALTHOUGH WE COULD SEE 1/2 INCH OR MORE FOR THE LASSEN PARK AREA AND PORTIONS OF THE SIERRA, WHICH COULD MEAN 3 TO 6 SNOW ALONG THE HIGHEST PEAKS. EASTERN PACIFIC RIDGE WILL MOVE THIS SYSTEM EAST BY LATE MONDAY, WITH THE NEXT MORE VIGOROUS SYSTEM DUE TO COME IN BY WEDNESDAY. SNOW LEVELS SHOULD RANGE FROM 4,000 TO 5,000 FEET WITH THIS STORM & PRECIPITATION ACCUMULATIONS WILL LIKELY BE MUCH HIGHER THAN THE SUNDAY SYSTEM. AT THIS TIME, IT LOOKS LIKE THAT STORM WILL LAST AT LEAST THROUGH NEXT SATURDAY. RANDY HARTLEY && .AVIATION... HIGH AND MID CLOUDS WILL CONTINUE TO SPREAD SOUTHEAST OVER NORTHERN CALIFORNIA MOVING SOUTHEAST DOWN THE EAST SIDE OF THE EASTERN PACIFIC RIDGE. VFR CONDITIONS ARE EXPECTED OVER RTES AS HIGH PRESSURE BUILDS AND MOVES INLAND ON FRI. NLY FLOW ALOFT AND OCNL CLOUD COVER WILL PRECLUDE FOG DEVELOPMENT IN THE INTERIOR CENTRAL VALLEY TONIGHT AND FRIDAY MORNING. && .STO WATCHES/WARNINGS/ADVISORIES...NONE. &&
