What happened

The episode as NWS HNX wrote it up.

An upper level low pressure system remained nearly stationary over southern California and continued to spread wrap around moisture into the area. This resulted in another afternoon of showers and thunderstorms on June 2. One cell produced a tornado east of Bakersfield while several others produced heavy rainfall and small hail. A slow moving thunderstorm produced flash flooding in downtown Coalinga which damaged several structures. The low moved east on June 3 and 4 which resulted in less moisture spreading into the area and fewer thunderstorms on the following afternoons.

.SYNOPSIS...
An area of low pressure will remain over Southern California
the next couple of days and look to influence the weather over
our forecast area. This feature will continue to bring a continued
threat of afternoon and evening thunderstorms over mainly the
mountain areas through at least Tuesday. However, isolated storms
are even possible over parts of the San Joaquin Valley and into
the Kern County desert. Temperatures will remain generally
seasonal for this time of year through Monday, and then warmer
than average temperatures are expected as high pressure builds
over the area.

.DISCUSSION...
This very stagnant pattern looks to continue at least through the
next couple of days. The cutoff low that has increased the
instability over the area the last couple of days is moving very
little and will continue to sit over southern California through
Tuesday. This will bring another day of showers and thunderstorms
for especially the higher elevations of the Sierra. With the upper
low circulation centered over central southern California the west
side of the valley will have a northerly flow and the Sierra will
have a more southerly flow. A few of the thunderstorms that
develop over the Sierra could meander into parts of the San
Joaquin Valley, such as what happened yesterday. Some of the
storms could become strong but the main impact with slow storm
movement will be heavy rainfall where the storms do develop. Of
course lightning, hail, and gusty winds will also be threats.
Near normal temperatures in the upper 80s to low 90s will be
likely once again today. It will also continue to feel humid
across many parts of the area as surface dew points are near 60
degrees in the SJV. So even though temperatures are running near
normal it will feel hotter than it actually is with the increased
humidities.

On Tuesday, weak ridging will move into the region and warm
temperatures to above normal and begin to bring us a break in the
action for at least the rest of the week. By next weekend another
trough will drop southward from the Pacific Northwest and once
again destabilize things. At this time, guidance has the trough
just skirting our area to the north but would not be surprised if
the trough moves a bit further south into central California. Even
if the trough does stay further north there will be increased
chances for afternoon showers and thunderstorms over the Sierra
crest. Now with meteorological summer officially here as of
yesterday temperatures are looking more seasonable, which
depending on who you ask is a bit of a shame. I guess it has to
come sooner or later. I prefer the latter of the two, but have to
admit we have been spoiled this year.

&&

.AVIATION...
Scattered thunderstorms from 20z today through 03z Monday across
the Sierra. Mountain obscuration in IFR conditions precip and
clouds. VFR conditions will prevail at MCE, MER, FAT, VIS, and BFL
through at least the next 24 hours.

&&

.HYDROLOGY...
Areal Flood advisory is in effect along the Kings River from Pine
Flat Dam to Kingsburg. Releases from Pine Flat dam have caused
minor flooding along parts of the Kings River.

The Merced River at Stevinson will remain above monitor stage
for the next several days.

.AIR QUALITY ISSUES...
None.
