A broad high pressure ridge brought well above average temperatures to the Central Valley. There were daily high maximum and minimum temperature records in the northern San Joaquin Valley.
Deaths and injuries are direct and indirect together, as the offices filed them. Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.

NWS Sacramento, CA wrote its last area forecast discussion before the first event at Jun 19, 9:25 PM PST, 2 hours 35 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SACRAMENTO CA 1025 PM PDT THU JUN 19 2008 .DISCUSSION... SHORT WAVE ENERGY NEAR 140W ROTATING BENEATH THE CLOSED UPPER LOW OVER THE NERN PAC WILL DIG THE UPPER TROF OVER THE ERN PAC AND ALLOW THE HIGH PRESSURE RIDGE FROM THE DESERT SW TO BUILD INTO NORCAL. MAX TEMPS ON FRI EXPECTED TO BE ABOUT 2 TO 4 DEG WARMER THAN THU OVER MOST AREAS. WEAK SHORT WAVE MOVING INSIDE 130W IS PRECEDED BY HIGH LEVEL CLOUDINESS THAT IS CURRENTLY MOVING ACROSS NORCAL. NWS SPEED TRACKER INDICATES THE BACK EDGE OF THE HIGH CLOUDINESS WILL BE NEAR TAHOE BY 17Z FRI...SO MUCH OF THE HIGH CLOUDINESS SHOULD TEMPORARILY CLEAR OUT FRI AFTN. SATELLITE INDICATES AN AREA OF ACCAS/FLOCCUS SW OF THE CENTRAL CA COAST WHICH WILL LIKELY ROTATE INLAND LATER TONIGHT AND FRI...BUT IS EXPECTED TO PRIMARILY PASS JUST S OF OUR AREA. AIR MASS WILL BE TOO DRY IN THE SUB-CLOUD LAYER BUT WE COULD SEE WHAT LOOK LIKE TOPS/REMNANTS OF CBS MAINLY TO OUR S DURING THE DAY ON FRI. MONO CO E OF THE SIERNEV CREST MAY SEE A RUMBLE OR TWO OF THUNDER FRI AFTN FROM THIS AREA OF CLOUDINESS. THE UPPER TROF OFF OVER THE ERN PAC IS FORECAST TO MOVE INSIDE 130W SAT AFTN AND BEGIN TO WEAKEN THE RIDGE OVER NORCAL. WE EXPECT THE ONSHORE BREEZE TO INCREASE AND RESULT IN A COOLING TREND...MOST NOTICEABLY THROUGH THE DELTA AND INTERIOR VLY ON SAT. GFS/NAM DIVERGE ON SOLUTIONS AFTER 48 HRS WITH THE GFS MOVING THE WAVE THROUGH NORCAL AND THE PAC NW WEAKER AND FASTER THAN THE NAM. SO THERE IS SOME UNCERTAINTY AS TO THE IMPACT OF THIS TROF ON INTERIOR NORCAL. THE GFS SOLUTION WOULD LESSEN THE IMPACT OF THE TROF ON INTERIOR NORCAL...INCLUDING LESS COOLING AND COOLING. MEANWHILE... THE 00Z SUN NAM CAPE FIELDS SUGGEST THE SWLY FLOW WILL BE STRONG ENOUGH TO FIRE OFF THE CONVECTION E OF THE SIERNEV CREST DURING SAT AFTN...AND PERHAPS OVER THE TRINITY MTNS. AMSU DATA INDICATE A MOIST PW PLUME /PWS 1.25 TO 1.30 INCHES W OF 140W/ AND A RATHER EXTENSIVE AREA OF RAIN BETWEEN 130-150W. THIS AREA OF CLOUDINESS/PCPN IS ROTATING BENEATH THE UPPER LOW AND LIFTING NEWD TOWARDS THE PAC NW. THUS...THE NAM SOLUTION WOULD SUGGEST THIS SHORT WAVE/UPPER TROF WILL BE SPREADING MORE CLOUDINESS/MOISTURE INTO NORCAL ON SAT THAN THE GFS. BEHIND THIS TROF...DRIER SWLY WILL PREVAIL OVER NORCAL ON SUN...WITH ONSHORE FLOW AND SYNOPTIC COOLING ON SUN CONTINUING A COOLING TREND. JHM .PREVIOUS EXTENDED DISCUSSION... GFS/CANADIAN KEEP THE RIDGE FLATTENED INTO EARLY NEXT WEEK AS A MORE PROGRESSIVE FLOW TAKES SHAPE ACROSS THE PACIFIC. THIS WOULD RESULT IN A SLOW COOLING TREND WITH A PERSISTENT WESTERLY FLOW ALOFT. THE FORECAST HAS HIGH TEMPERATURES COOLING INTO THE UPPER 80S IN MANY AREAS BY SUNDAY...AND REMAINING NEAR NORMAL THROUGH NEXT WEEK. SG && .AVIATION... VFR WITH BKN CIRRUS MOVING NEWD ACROSS NORCAL INTO FRI. SURFACE WINDS WILL BE LIGHT DUE TO WEAK PRESSURE GRADIENTS. HIGH PRESSURE FROM THE DESERT SW WILL BUILD OVER NORCAL WITH WARMER TEMPS ON FRI. SURFACE WINDS EXPECTED TO PRIMARILY TURN LIGHT NWLY DURING THE DAY. && .STO WATCHES/WARNINGS/ADVISORIES...NONE. &&
