AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SACRAMENTO CA 910 PM PDT SUN MAR 30 2008 .DISCUSSION...WATER VAPOR IMAGERY CONTINUES TO SHOW A TROUGH OF LOW PRESSURE OVER THE WEST...WITH THE TROUGH AXIS SHIFTING NOW TO THE EAST. AS A RESULT...DRIER NORTHWESTERLY FLOW IS STARTING TO FILTER OVER NORTHERN CALIFORNIA. THIS CAN BE SEEN ON THE FOG PRODUCT...WITH SKIES CLEARING DOWN THE WEST SIDE OF THE VALLEY AND JUST A FEW LOWER CLOUDS LINGERING OVER THE SIERRA AND FOOTHILLS. TEMPERATURES ARE RUNNING 0 TO 8 DEGREES COOLER THAN THIS TIME LAST NIGHT...AND DEW POINT ARE ALSO RUNNING 1 TO 11 DEGREES COOLER. THEREFORE...EXPECT ANOTHER CHILLY NIGHT ACROSS THE REGION...WITH TEMPERATURES DIPPING INTO THE MID AND UPPER 30S IN THE VALLEYS. WILL UPDATE THE FORECAST THIS EVENING TO TWEAK TEMPS A BIT AND REFRESH THE SKY WORDING. OTHERWISE...CURRENT FORECAST LOOKS ON TRACK...WITH DRY AND WARMER CONDITIONS PREVAILING TOMORROW. PALMER .PREVIOUS DISCUSSION (ISSUED AT 330 PM)...SPLIT IN THE FLOW CONTINUES ALONG THE W COAST WITH SHORT WAVE IN THE SRN STREAM CURRENTLY MOVING TOWARDS KLAS. THIS SYSTEM PRODUCED A BAND OF PCPN OVER THE SIERNEV MAINLY FROM YOSEMITE SWD EARLY THIS MORNING...AND SUBSIDENCE IN ITS WAKE DISSIPATED THE CLOUDS IN THE VLY. THIS SYSTEM WILL CONTINUE TO MOVE EWD AND LESSEN ITS IMPACT ON NORCAL TONIGHT. UPSLOPE FLOW OVER THE SIERNEV CONTINUED TO RESULT IN BKN-OVC CEILINGS DURING THE DAY ON SUN. BUFKIT DATA AND GFS CROSS SECTIONS SUGGEST THIS LOW LEVEL MOISTURE WILL NOT BE SCOURED OUT OVERNITE AS MOISTURE REMAINS TRAPPED BELOW THE SUBSIDENCE INVERSION...AND WIND CONVERGENCE BOUNDARY BETWEEN 850-700 MBS. WIND DIRECTION EFFECTS ALSO A FACTOR AND DISCUSSED IN THE NEXT PARAGRAPH. SHORT WAVE ENERGY IN THE NRN STREAM MOVING ACROSS ORE IS MUCH DRIER...MFR PW ONLY .25 INCH...BUT COOLER AND WILL MAINTAIN CAA OVER NORCAL WITH NWLY FLOW. THE OFFSHORE CELLULAR FORM CLOUDS INDICATE THIS...BUT THE WIDELY SPACED CU IS INDICATIVE OF THE LACK OF PW OR DRIER AIR IN THE NRN BRANCH. IN THE WAKE OF THIS SHORT WAVE ENERGY...SURFACE HIGH PRESSURE WILL BUILD ACROSS ORE AND THE GREAT BASIN...AND LIGHT E OR NELY FLOW WILL DEVELOP OVER THE NRN MTNS AND NRN SIERNEV. THE GFS CROSS SECTION OVER THE SIERNEV SUGGESTS THE ELY DOWNSLOPE FLOW WILL DRY OUT THIS LOWER LEVEL MOISTURE AFT 06Z MON...BUT IT MAY ALSO SPREAD SOME OF THE CLOUD COVER DOWNSLOPE BEFORE THE CLOUD COVER ERODES. THIS MAY OCCUR OVER THE NRN MTNS AS WELL...AFFECTING PARTS OF SHASTA CO. BENIGN WX EXPECTED OVER NORCAL MON AS WE WILL BE IN BETWEEN WX SYSTEMS. A SLIGHT MODERATION IN TEMPS IS EXPECTED. THEN...THE SPLIT FLOW PATTERN OVER THE PAC WILL RESULT IN A COUPLE OF CLOSED CUT-OFF LOWS FORMING NEAR 30N THIS WEEK. APPEARS THE GFS/EURO ARE FORECASTING THE TROF ALONG 150W TO DIG SEWD AND FORM A CLOSED CUT-OFF LOW VCNTY OF 32N/130W BY TUE...WITH PCPN SPREADING INLAND MAINLY WED INTO THU MORNING. THIS SYSTEM IS FORECAST TO TRACK ACROSS SOCAL/NRN BAJA...SO IT WILL BE MAINLY AFFECTING THE SRN PORTION OF THE FORECAST AREA FROM I-80 SWD. THE DRIER NLY FLOW FROM THE NRN STREAM IS FORECAST TO KEEP OUR NRN ZONES PCPN FREE...AND THESE ADJUSTMENTS WERE MADE IN THE GRIDS AND TEXT FORECASTS THIS AFTN. THE GFS SHOWS A PW PLUME OF 1.0 TO 1.2 INCHES ROTATING NEWD INTO THE CENTRAL CA COAST BY WED PROVIDING MOISTURE FOR THIS SYSTEM FOR PCPN OVER THE SRN PORTION OF THE FORECAST AREA. THE SECOND SYSTEM...CURRENTLY W OF THE DATELINE...IS FORECAST TO FORM A SECOND CLOSED CUT-OFF LOW FURTHER W NEAR 30N/145-150W WHICH WOULD BUILD A DOWNSTREAM RIDGE ALONG THE W COAST LATER IN THE WEEK. THIS WOULD GIVE NORCAL JUST THE ONE SHOT OF PCPN NEXT WEEK INSTEAD OF MULTIPLE CHANCES. THE EURO SUGGESTS BOTH BRANCHES OF THE SPLIT FLOW MAY PHASE INTO A WEAK LONGER WAVE POSITIVELY-TILTED TROF BY SUN...BUT PCPN WOULD BE MUCH LIGHTER THAN THE MID WEEK SYSTEM. MEANWHILE THE GFS SHOWS LESS PHASING WHICH MAY BENEFIT SOCAL AS THIS SYSTEM TAPS THE HIGHER PW RESERVOIR S OF 30N AND RESULTS IN A MUCH WETTER SCENARIO THAN THE EURO...ESPECIALLY FOR SOCAL NEXT SUN. JHM .EXTENDED DISCUSSION (WEDNESDAY NIGHT THROUGH SUNDAY)... THE MEDIUM RANGE MODELS SEEM TO BE CONVERGING ON MORE OF A SPLIT- FLOW PATTERN FOR WEDNESDAY NIGHT...WITH AN UPPER LOW DIVING INTO SOUTHERN CALIFORNIA, AND A HIGH PRESSURE RIDGE BUILDING INTO THE PACIFIC NORTHWEST. THIS COULD CONTINUE TO PROVIDE SHOWERS IN THE SOUTHERN END OF OUR ZONES THAT NIGHT...BUT THE RIDGE SHOULD KEEP AREAS DRY THURSDAY AND FRIDAY. ANOTHER UPPER LOW IS FORECAST TO MOVE TOWARD SOUTHERN CALIFORNIA BY SUNDAY, SO HAVE SLIGHT CHANCE PROBABILITIES ACROSS OUR WESTERN ZONES SATURDAY, WITH INCREASING CHANCES SUNDAY AS THE LOW MOVES INTO THE STATE. RANDY C. HARTLEY .AVIATION... ACROSS THE LOWER ELEVATIONS, VFR CONDITIONS PREVAIL AS RIDGE BUILDS ACROSS THE EASTERN PACIFIC AND A LIGHT NORTHERLY WIND DOMINATES THE WEATHER PICTURE. RESIDUAL LOWER LEVEL MOISTURE WILL KEEP POCKETS OF MARGINAL VFR TO IFR CEILINGS IN SPOTS OVER THE SIERRA. OTHERWISE... REGION IS SEEING VARYING AMOUNTS OF CLOUDS FROM 4,000 TO 8,000 FEET WITH THE POSSIBILITY OF LOCALLY GUSTY NORTHWEST WIND. RANDY HARTLEY && .STO WATCHES/WARNINGS/ADVISORIES...NONE. &&
