What happened

The episode as NWS HNX wrote it up.

The 2004-2005 cool season in Interior Central California was one of the better rain accumulation years recently. Rain periods with snow at the higher elevations started in mid-October and continued consistently through mid-May. This water year was in stark contrast to the averaged below normal rainfall from the past 6 years. Generally the Central and South San Joaquin Valley ended with 140% of rainfall normals while the higher elevation snowpack for the Southern Sierra Nevada finished at 185% of normal and the Kern River Basin on the Southern end of the S.Sierra Nevada at 154% of normal. From October through May every month had above normal rain/snow amounts with the exception of just below normal precipitation for November and April. October, December, and May had significantly large amounts of rain/snow. Furthermore, the mountain snowpack was marked by its staying power as cool weather persisted into June and reservoirs were able to hold more water for a longer period of time than ever seen before. Campgrounds at the higher elevations of the Southern Sierra Nevada in Yosemite National Park did not open for the summer of 2005 due to the large and late snowpack.

.SHORT TERM...FOR THE CENTRAL CALIFORNIA INTERIOR...VIS LOOP
INDICATING SKIES ARE MOSTLY CLEAR OVER THE CENTRAL CA INTERIOR
THIS EVENING AS THE UPPER LOW OVER THE PAC NW AND IT/S ASSOCIATED
TROUGH EXTENDING SOUTHWARD INTO NORCAL HAS HAD LITTLE IMPACT ON
OUR CWFA. TEMPS ARE GENERALLY RUNNING 6-8 DEG F ABOVE YDAY AT THIS
TIME. WITH WINDS EXPECTED TO SLOWLY DIMINISH OVERNIGHT AND SKIES
EXPECTED TO REMAIN CLEAR...ANTICIPATE OVERNIGHT MIN TEMPS TO REACH
FORECASTED VALUES. THE REMAINDER OF THE FORECAST LOOKS ON TARGET FOR
TONIGHT AND WEDNESDAY SO WILL NOT UPDATE THE CURRENT GRID AND TEXT
PACKAGES THIS EVENING.

00Z NAM/NGM/GFS INDICATE THAT THE PAC NW TROUGH WILL MOVE INTO THE
INTERMOUNTAIN WEST OVERNIGHT. A STRONG UPPER VORT IS THEN EXPECTED TO
DROP BEHIND THE DEPARTING TROUGH AS IT DEEPENS OVER THE NORTHERN
ROCKIES WEDNESDAY AND THURSDAY. THIS SYSTEM IS EXPECTED TO TAKE AN
INSIDE SLIDER TRAJECTORY AND DROP SOUTHEAST OVER NV THURSDAY NIGHT...
RESULTING IN A DRY COLD FRONTAL PASSAGE USHERING IN ANOTHER SHOT OF
COOLER AIR ALONG WITH A BRIEF STRENGTHENING OF P-GRADS AND SUBSEQUENT
WINDY CONDITIONS ACROSS THE KERN MOUNTAINS AND DESERTS FOR THURSDAY
EVENING. SINCE HIGH WIND WARNING CRITERIA IS NOT ANTICIPATED...DO
NOT ANTICIPATE THE NEED FOR A HIGH WIND WATCH. HOWEVER...WILL LIKELY
NEED TO ISSUE A WIND ADVISORY FOR THESE AREAS AS THE TIME APPROACHES.
WITH THE MODELS GOING A BIT SLOWER ON THE TIMING OF THIS SYSTEM...THE
ANTICIPATED COOLING FOR THURSDAY WILL PROBABLY BE SLOWED DOWN A BIT.
MAX TEMPS FOR THURSDAY WILL PROBABLY NEED TO BE BUMPED UP SOME AS 00Z
GUIDANCE IS SEVERAL DEG F ABOVE WHAT IS CURRENTLY FORECASTED. WILL
MAKE THIS RECOMMENDATION TO THE MIDNIGHT SHIFT. RH PROGS INDICATING
ANY MOISTURE WITH THIS SYSTEM WILL REMAIN NORTHEAST OF OUR AREA SO
THE MENTIONED CLEAR SKIES FORECAST LOOKS GOOD. ANTICIPATE THAT MAX
TEMPS ON FRIDAY WILL BE WELL BELOW SEASONAL NORMALS FOR EARLY JUNE AS
A COOL AND DRY NORTHWEST FLOW BRINGS A GOOD SHOT OF CAA TO CENTRAL
CA.  DS

.LONG TERM...FROM PREVIOUS DISCUSSION...FRIDAY NIGHT THROUGH
TUESDAY...THE DISTRICT REMAINS UNDER A WEAKLY CYCLONIC BUT DRY FLOW
THROUGH AT LEAST SUNDAY NIGHT. MODERATE ONSHORE FLOW CONTINUES SO
EXPECT MILD TEMPERATURES WITH OCCASIONALLY BREEZY CONDITIONS BELOW
THE KERN COUNTY MOUNTAIN PASSES. SOME DISAGREEMENT GOING INTO THE
NEXT WORK WEEK, AS THE 00Z GFS TENDS TO BE MUCH DEEPER WITH A SERIES
OF DISTURBANCES MOVING INTO THE PACNW THAN THE ECMWF. PREFER A WEAKER
AND MORE PROGRESSIVE, QUASI-ZONAL PATTERN WHICH WILL REINFORCE THE
ONSHORE FLOW AND PROVIDE ONLY VERY SLIGHT COOLING. GENERALLY CLEAR
SKIES THROUGH THE PERIOD ALTHOUGH A FEW CUMULUS WILL LIKELY APPEAR
EACH AFTERNOON OVER THE SIERRA NEVADA.  BURGER

.AVIATION...VFR CONDITIONS WILL CONTINUE FOR ALL CENTRAL AND
SOUTHERN SAN JOAQUIN VALLEY LOCATIONS THROUGH AT LEAST 06Z
THURSDAY. REFER TO TAFS AT KMCE, KFAT, AND KBFL.  JSN
