NWS Hanford, CA wrote its last area forecast discussion before the first event at May 17, 2:00 PM PST, 2 hours 25 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SAN JOAQUIN VALLEY - HANFORD CA 300 PM PDT WED MAY 17 2006 .SHORT TERM...ISOLATED THUNDERSTORMS HAVE INDEED FIRED OVER THE SIERRA AND KERN COUNTY MOUNTAINS AND A FEW CELLS HAVE DEVELOPED OVER NORTHWEST SAN BERNARDINO COUNTY. THUS FAR, NO SEVERE STORMS HAVE BEEN DETECTED BY RADAR IN THE HANFORD WARNING AREA, HOWEVER STRONG TO SEVERE CELLS HAVE POPPED OVER THE VENTURA AND SANTA BARBARA COUNTY MOUNTAINS. WATER VAPOR IMAGERY SHOWS LITTLE TO NO CHANGE IN THE POSITION OF THE GREAT BASIN HIGH AND EASTERLY TO SOUTHEAST FLOW CONTINUES. THIS FLOW WILL BLOW ANVILS AND CONVECTIVE DEBRIS CLOUDS OVER AND ACROSS THE SAN JOAQUIN VALLEY, HOWEVER I STILL DONT THINK A BIG CONVECTIVE THREAT EXISTS FOR THE LOW LANDS. WILL KEEP THE ISOLATED THUNDER IN THE GRIDS FOR THE MOUNTAINS AND KERN COUNTY DESERT THIS EVENING. MODELS ARE IN GOOD AGREEMENT IN MOVING THE HIGH CENTER EAST ON THURSDAY THUS THE THUNDERSTORM THREAT SHOULD BE CONFINED TO THE SIERRA CREST. WORDS CANNOT DESCRIBE THE NUMBER OF UNCERTAINTY PROBLEMS FACING FORECASTERS BEGINNING FRIDAY AND LASTING INTO NEXT WEEK. FIRST OF ALL, THE LONGWAVE PATTERN OVER THE U.S. IS VERY STABLE, WITH THE LARGE LOW IN THE NORTHEAST, AND THE VERY LARGE HIGH PRESSURE RIDGE OVER THE ROCKIES. THESE SIZABLE SYSTEMS TEND TO MOVE AND OR WEAKEN VERY SLOWLY, WHILE WEATHER FORECAST MODEL OUTPUT MANY TIMES TRIES TO WEAKEN AND OR MOVE THEM MUCH QUICKER THAN WHAT ACTUALLY OCCURS. WITH THIS SAID, THE FORECAST FOR THE FRIDAY NIGHT THROUGH SATURDAY IS BASED ON VERY LOW CONFIDENCE MODEL SOLUTIONS. HAVE BASED THE FORECAST ON THE GENERAL MODEL TREND, BUT HAVE DRASTICALLY REDUCED THE CHANCES OF PRECIPITATION AND THE FORECAST AMOUNTS WITH THUNDERSTORM CHANCES COMMENCING ON FRIDAY NIGHT AND CONTINUING THROUGH SATURDAY AS BOTH THE NAM AND GFS MODELS MOVE THE RIDGE EAST AND BRING THE LOW, WHICH IS CURRENTLY OUT NEAR 30/140W CLOSER TO THE WEST COAST WHILE SWINGING A TROUGH OF LOW PRESSURE AND A VORTICITY CENTER INTO THE BAY AREA FRIDAY NIGHT. THIS FEATURE IS THEN PROGGED TO SWING EAST ON SATURDAY. THE FORECAST MODELS HAVE VERY HIGH POPS (AS HIGH AS 100%) OVER PARTS OF THE AREA AS WELL AS PROJECTED RAINFALL AMOUNTS OF 1-2 INCHES IN THE SIERRA, IN ADDITION TO LIGHTER AMOUNTS IN THE SAN JOAQUIN VALLEY. IN COORDINATION WITH OTHER NWS OFFICES, HAVE INTRODUCED 30% POPS TO THE NORTHERN PART OF THE FORECAST AREA AND IN COORDINATION WITH THE RIVER FORECAST CENTER IN SACRAMENTO HAVE KEPT THE PROJECTED RAINFALL AS LIGHT AND SPOTTY. WILL OBVIOUSLY NEED TO WATCH THE NEXT FEW MODEL RUNS TO SEE IF THE HEAVY RAIN THREAT IS REAL OR JUST A PRODUCT OF FORECAST MODELS HAVING A DIFFICULT TIME PREDICTING A MID MAY WEATHER EVENT. STAY TUNED. .LONG TERM...SATURDAY NIGHT THROUGH WEDNESDAY...LOW CONFIDENCE IN THE FORECAST THROUGH THE EXTENDED PERIOD AS MODELS CONTINUE TO HAVE INCONSITENCIES FROM RUN TO RUN IN HANDLING THE TROUGH OVER THE EASTERN PACIFIC. THE 12Z GFS KEEPS THE TROUGH OFF THE CENTRAL CA COAST SATURDAY NIGHT...LIFTING IT THROUGH THE CWFA SUNDAY BRINING PRECIP TO THE ENTIRE CWFA...THEN MOVING IT EAST MONDAY MORNING. THE 12Z ECMWF IS SLOWER THAN THE GFS BUT ALSO INDICATES THE SOUTH END OF THE TROUGH LIFTING OVER THE REGION SUNDAY AS WELL...WHICH IS A CHANGE FROM THE PREVIOUS RUNS WHICH HELD IT OFF THE COAST. THE UKMET IS ABOUT A DAY SLOWER WITH THIS WHOLE PATTERN. CAN NOT IGNORE THE GFS SOLUTION SINCE THE ECMWF OF LEANING THAT WAY TOO...SO HAVE ADDED CHANCE POPS TO THE SIERRA AND SLIGHT CHANCE POPS ACROSS THE REMAINDER OF THE AREA FOR SUNDAY. THE GFS AND ECMWF BOTH INDICATE A LOW REMAINING SOMEWHERE OFF THE PACNW COAST MONDAY AND TUESDAY WITH MOST OF THE ENERGY MOVING INTO THE NORTHERN HALF OF CALIFORNIA. GFS STILL TRYING TO BRING SOME PRECIP ACROSS THE NORTHERN HALF OF THE CWFA...BUT FOR NOW PREFER TO JUST KEEP 10 PERCENT POPS IN THE GRIDS AND NOT MENTION IN THE ZONES AS CONFIDENCE IS VERY LOW. AS FAR AS TEMPS...GFS BRINGS CONSIDERABLE COOLING TO THE REGION SUNDAY AS IT BRINGS THE TROUGH THROUGH...DROPPING TEMPERATURES INTO THE UPPER 60S AND LOWER 70S. IF THE TROUGH DOES COME THROUGH THERE WILL DEFINATELY BE SOME COOLING BUT HAVE OPTED TO NOT GO QUITE THAT COOL AT THIS TIME. EXPECT TEMPERATURES TO RECOVER BACK TO NEAR NORMAL BY WEDNESDAY AS HEIGHTS RISE WITH MORE ZONAL FLOW. && .AVIATION....FOR SPECIFIC DETAILS...VFR CONDITIONS CAN BE EXPECTED THROUGH 00Z FRIDAY.
