NWS Sacramento, CA wrote its last area forecast discussion before the first event at Jun 11, 3:00 PM PST, 4 hours earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SACRAMENTO CA 400 PM PDT THU JUN 11 2009 .DISCUSSION... SIMILAR WEATHER PATTERN AS YESTERDAY AS THE SOUTHERN BRANCH OF A SPLIT UPPER LEVEL FLOW HAS BROUGHT A LONGWAVE TROUGH OVER CALIFORNIA. AT PRESENT A CLOSED UPPER LOW IS OVER THE SOUTHERN OREGON COAST AND HAS BEEN NEARLY STATIONARY THERE FOR THE LAST 12 TO 24 HOURS. THIS LOW WILL SLOWLY DROP SOUTH INTO INTERIOR NORTHERN CALIFORNIA OVER THE NEXT FEW DAYS. RADAR IMAGERY SHOWS THAT SCATTERED SHOWERS AND THUNDERSTORMS HAVE BEEN DEVELOPING ALONG THE COASTAL RANGE AND SOUTHERN CASCADE CRESTS SINCE AROUND NOON AND HAVE BEEN ADVECTING TO THE NORTH AND EAST. SOME OF THE MORE POTENT CELLS MAY BE BRINGING SMALL HAIL...LOCALLY GUSTY WINDS AND BRIEF HEAVY RAIN. AN AREA CELLS HAVE BEGUN TRAINING OVER THE REDDING AREA AS OF THIS WRITING...EXPECTING THAT THEY MAY SEE SOME DECENT RAINFALL OVER THE NEXT FEW HOURS. TEMPERATURES ALONG MUCH OF THE VALLEY THIS AFTERNOON ARE RUNNING 2-5 DEGREES WARMER THAN YESTERDAY WITH ABUNDANT INSOLATION WITH TEMPERATURES OVER HIGHER ELEVATIONS AROUND WHERE THEY WERE YESTERDAY. SHOWERS WILL SLOWLY DECREASE IN COVERAGE THIS EVENING...ALTHOUGH EXPECTING A FEW SHOWERS TO LINGER OVER HIGHER ELEVATIONS OVERNIGHT. EXPECTING MUCH OF THE SAME FRIDAY AS THE UPPER LOW DRIFTS VERY SLOWLY SOUTHWARD TOWARDS NORCAL. A SHORTWAVE OFF THE SOCAL COAST WILL MAKE ITS WAY NORTHEAST AND INTO CENTRAL CALIFORNIA FRIDAY. THIS SHORTWAVE WILL LIKELY INCREASE THE COVERAGE OF SHOWERS AND THUNDERSTORMS ALONG THE MOUNTAINS. IT WILL ALSO BRING MORE CLOUDINESS...LIKELY LIMITING FRIDAY HIGHS TO A FEW DEGREES COOLER THAN TODAYS. WINDS THROUGH THE CARQUINEZ STRAIT TONIGHT INTO FRIDAY MORNING WILL BE COMPARABLE TO THE LAST FEW DAYS...BUT EXPECTING A CONTINUED DETERIORATING MARINE LAYER AND THUS LESS OF A MARINE LAYER INTRUSION. THE UPPER LOW WILL MOVE OVERHEAD SATURDAY...LIKELY BRINGING ANOTHER ROUND OF SHOWERS AND THUNDERSTORMS OVER THE MOUNTAINS. HAVE ALSO INCREASED CHANCES OF PRECIPITATION OVER THE VALLEY ON SATURDAY AND SATURDAY NIGHT. THE OVERALL PATTERN WILL BE SLOW TO CHANGE WITH CONTINUED SHORTWAVES MOVING THROUGH THE AREA. AS SUCH HAVE CONTINUED THE CHANCES OF SHOWERS AND THUNDERSTORMS OVER THE MOUNTAINS THROUGH THE SHORT TERM PERIOD. DANG .EXTENDED DISCUSSION... LONG RANGE MODELS PLACE THE UPPER LEVEL TROUGH OVER CALIFORNIA WITH LITTLE SHIFTING TO THE SOUTHEAST AS CLOSED LOW PRESSURE SYSTEM DEVELOPS BY TUESDAY MORNING. GFS IS A LITTLE MORE AGGRESSIVE BY BRINGING MORE POSITIVE VORTICITY CLOSE TO OUR CWA. DUE TO THIS SCENARIO...SLIGHT CHANCES OF PRECIP HAVE BEEN ADDED TO THE NORTHERN MOUNTAINS...COASTAL RANGE...AND SIERRA NEVADA DURING THIS PERIOD. AFTER TUESDAY...MODELS SOMEWHAT AGREE WITH CUTTING THE UPPER LOW OFF AND MOVING IT TO SOUTHERN CALIFORNIA MID-TO-LATE WEEK. BY FRIDAY...THIS CUT-OFF LOW RETROGRADES TO THE PACIFIC OCEAN...SOUTHWEST OF THE SOUTHERN CALIFORNIA COAST. ON SATURDAY...MODELS HINT THAT THE CUTOFF LOW WILL BE REABSORBED WITH THE JET STREAM...BRINGING THE TROFFY PATTERN BACK TO CALIFORNIA. AT THIS POINT MODELS DIVERGE SIGNIFICANTLY...AND THEREFORE CONFIDENCE IN SOLUTIONS FOR THE WEEKEND OF JUNE 19 IS LOW. GARCIA && .AVIATION... SHOWERS AND THUNDERSTORMS MOVING EASTWARD NEAR RDD AND RBL TERMINALS THIS AFTERNOON...AS WELL AS CUMULUS CLOUDS WITH A FEW SHOWERS DEVELOPING ALONG THE SIERRA NEVADA AND COASTAL RANGE. OTHERWISE...GENERAL VFR CONDITIONS IN THE SOUTHERN SACRAMENTO AND NORTHERN SAN JOAQUIN VALLEYS THROUGH THE NIGHT. WESTERLY FLOW ALOFT THIS EVENING SHIFTING TO THE SOUTHWEST BY FRIDAY MORNING. EXPECT MORE SHOWER ACTIVITY OVER THE HIGHER ELEVATIONS AND NORTHERN SAC VALLEY FRIDAY AFTERNOON. GARCIA && .STO WATCHES/WARNINGS/ADVISORIES...NONE. &&
