Area Forecast Discussion
National Weather Service San Joaquin Valley - Hanford CA
151 PM PDT Sun May 26 2019

.SYNOPSIS...A storm system will bring scattered thunderstorms
to the central California interior through early this evening
with showers and higher elevation snow in the mountains. The
storm will exit into the Great Basin on Memorial Day yet clouds
and a few residual showers will linger in the mountains.
Otherwise, unseasonably cool weather will continue through the
holiday. Temperatures will warm to seasonable levels by the
middle of next week with a daily chance of showers over the
mountains.

&&

.DISCUSSION...Our "February in May" weather pattern has made
its return to the central California interior today. Saturday's
seasonably warm air mass was chased away by an eastward moving
cold front early this morning. The front brought nominal
precipitation with its passage, but what's more impressive is
how dramatically cooler temperatures are in its wake this
afternoon...15 to 25 degrees lower in most locations compared to 24
hours ago!  Scattered thunderstorms are rumbling about in the post
frontal environment this afternoon. In the meantime, numerous
showers are occurring over the mountains. Above roughly 5,000 feet,
it's a wintry scene today with accumulating snow and potentially
hazardous, slick travel.

Our throwback to winterlike weather can be blamed on an upper
level low which originated in the Gulf of Alaska only a few days
ago and is now centered over northern California.  It's very unusual
for a low pressure system so deep and so cold to come this far south
at this time of year. 500 MB temperatures near the center of this
low are near -27C. Cooling aloft today with warming in the lowest
levels has created a very unstable environment, particularly in the
San Joaquin Valley. We are also in the left front quadrant of the
upper level jet which is now situated over southern California. All
of these synoptic factors combined support the development of
isolated strong to severe thunderstorms with hail and gusty winds
into the early evening hours today. A few of those thunderstorms
could spawn a funnel cloud. Compared to yesterday, the storms are
quick movers, so any heavy precip they bring will be short lived.

The threat of thunderstorms will diminish after sunset as the
atmosphere stabilizes. Nonetheless, showers will likely continue
over the mountains through tonight as the cold core low drifts
southeastward and exits into southern Nevada by daybreak. Brisk
westerly winds through and below the Kern county mountain passes
will diminish by then. The weather on Memorial Day will be a
slight improvement over today, but still not ideal for outdoor
plans, especially over the mountains where skies will remain
rather cloudy and some light precip is possible in some locations.
Temperatures will remain well below normal for the holiday even
where sunshine makes an appearance. Otherwise, the storm system
that's currently impacting us will end up over the Four Corners
region by Monday night.

In spite of how distant this storm will be by then, don't think it
won't have any influence on our weather pattern beyond Monday night.
An amplifying ridge of high pressure over the southeastern states
will impede the normal eastward movement of storm systems across the
nation and keep an upper level trough carved out over the Western
states for much of the week. The models bring at least two more
short waves southward into the Golden State in the 3 to 7 day
period. Timing these disturbances will be next to impossible, so
each and every day from Tuesday through next weekend will bring a
chance of precipitation to the Sierra. The system during midweek
could bring also bring showers southward into the Kern county
mountains Wednesday and Thursday. The good news is that temperatures
will finally bounce back to seasonable levels Wednesday and remain
pretty close to normal through Friday. Temperatures could trend
slightly warmer next weekend but only if the block in the upper air
pattern weakens. The longer range models do forecast troughiness
to linger over the Great Basin on days 6 and 7, hence the reason for
carrying shower possibilities over the Sierra through next Sunday.

&&

.AVIATION...
Scattered thunderstorms can be expected in the San Joaquin Valley
and adjacent foothills through 03z Monday. MVFR conditions with
areas of IFR will occur along the west slopes of the Sierra and
the north facing slopes of the Tehachapi mountains through at
least 18z Monday. Additionally, wind gusts in excess of 35 knots
will occur in the Kern county desert until 12z Monday. VFR
conditions can be expected elsewhere over the central California
interior during the next 24 hours.
