The episode as NWS HNX wrote it up.
Strong monsoonal moisture push came into the area early in the morning hours. This resulted in a broad area of convection (MCS) across western Arizona and southeastern California. These storms moved towards Kern County quickly resulting in some brief thunderstorm outflow winds and localized heavy rainfall.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JOAQUIN VALLEY - HANFORD CA
305 AM PDT WED JUL 1 2015
.SYNOPSIS...
THUNDERSTORMS WILL SPREAD INTO KERN COUNTY THIS MORNING...THEN
ACROSS MUCH OF THE CENTRAL CALIFORNIA INTERIOR TODAY AND THURSDAY AS
MONSOONAL MOISTURE CONTINUES TO SURGE INTO THE REGION. TEMPERATURES
WILL BE NEAR TO ABOVE NORMAL THE NEXT FEW DAYS.
&&
.DISCUSSION...
NOCTURNAL THUNDERSTORMS DEVELOPED OVER SOUTHEASTERN SAN BERNARDINO
COUNTY OVERNIGHT AND HAVE SPREAD WESTWARD THE LAST FEW HOURS.
THUNDERSTORMS COULD REACH THE EASTERN KERN COUNTY DESERT BY DAYBREAK
AND CONTINUE INTO THE KERN AND SOUTHERN TULARE COUNTY MOUNTAINS THIS
MORNING WITH A THUNDERSTORM OR TWO DRIFTING INTO THE SOUTHERN SAN
JOAQUIN VALLEY. THIS HAS LED TO AN INCREASE IN POPS FOR THIS MORNING
AND THE ADDITION OF SLIGHT CHANCE POPS TO THE SOUTHERN HALF OF THE
SAN JOAQUIN VALLEY THIS AFTERNOON AND EVENING.
THE MODELS HAD BEEN FORECASTING A DEEPER MONSOONAL MOISTURE SURGE
INTO AT LEAST THE SOUTHERN PART OF THE CENTRAL CALIFORNIA INTERIOR
FOR TODAY...BUT THE OBSERVED CONVECTION HAS BEEN STRONGER THAN THE
MODELS HAD FORECAST.
AS EXPECTED TEMPERATURES WARMED TO WELL ABOVE NORMAL TUESDAY WITH
BOTH BAKERSFIELD AND FRESNO REACHING 106 DEGREES. RESIDUAL WARMTH
AND CIRRUS OVER CENTRAL CALIFORNIA HAVE KEPT OVERNIGHT TEMPERATURES
UP...RESULTING IN A WARM START TO TODAY.
CLOUDS ASSOCIATED WITH THE MONSOONAL SURGE WILL MAKE THE TEMPERATURE
FORECAST TRICKY THE NEXT FEW DAYS. THE FORECAST OF WELL ABOVE NORMAL
TEMPERATURES TODAY WAS BASED ON MOSTLY CLEAR SKIES OVER THE SAN
JOAQUIN VALLEY. SHOULD THE CLOUD COVER BE MORE EXTENSIVE THAN
ORIGINALLY THOUGHT...TEMPERATURES COULD BE CAPPED. IT IS POSSIBLE
THAT MERCED COULD BE WARMER THAN BAKERSFIELD TODAY AS MERCED MAY NOT
SEE THE THICK CLOUD COVER THAT WILL BLANKET AREAS TO THE SOUTH.
THE UPPER-LEVEL RIDGE IS FORECAST TO REMAIN OVER THE GREAT BASIN
THROUGH AT LEAST THURSDAY NIGHT...KEEPING A SOUTHEAST FLOW ALOFT
OVER CALIFORNIA AND CONTINUING TO ADVECT MONSOONAL MOISTURE INTO THE
STATE. AS A RESULT...THUNDERSTORMS WILL BE POSSIBLE OVER MUCH OF THE
CENTRAL CALIFORNIA INTERIOR THE NEXT TWO DAYS.
THE RIDGE IS FORECAST TO WEAKEN BEGINNING FRIDAY. BY SUNDAY...THE
FLOW ALOFT IS FORECAST TO TURN SOUTHERLY...AND THEN SOUTHWESTERLY
FOR THE FIRST PART OF NEXT WEEK AS AN UPPER-LEVEL LOW WEST OF THE
CENTRAL CALIFORNIA COAST BECOMES THE DOMINANT WEATHER FEATURE.
&&
.AVIATION...
ISOLATED TO SCATTERED THUNDERSTORMS CAN BE EXPECTED OVER THE
MOUNTAINS AND DESERT THROUGH TONIGHT WITH LOCAL MVFR CEILINGS OVER
THE HIGHER TERRAIN. A FEW THUNDERSTORMS COULD DRIFT INTO THE SAN
JOAQUIN VALLEY AND ADJACENT FOOTHILLS FROM FRESNO COUNTY SOUTHWARD
TODAY THROUGH EARLY THIS EVENING. OTHERWISE...VFR CONDITIONS WILL
PREVAIL THROUGHOUT THE CENTRAL CALIFORNIA INTERIOR DURING THE NEXT
24 HOURS.
