Area Forecast Discussion
National Weather Service Hanford CA
227 PM PDT Tue Mar 10 2020

.SYNOPSIS...
A system will approach the coast of California through Wednesday.
Significant rainfall is likely in the Kern County mountains and
desert Tuesday afternoon and Tuesday night, along with a chance of
stronger thunderstorms through this evening. This storm system
should stall just offshore of California Wednesday, before
shifting southward Wednesday night and Thursday. Another system
may potentially impact the region by the weekend.

&&

.DISCUSSION...
Current analysis has the upper level low situated at 32N/125W.
Ahead of the upper low, light showers have spread across the SJV
and Kern County desert this morning, with generally light amounts.
Cutoff low pressure will continue to slowly drift northeast, but
will remain around 300 miles off Point Conception. The region will
experience strong upper level difluent flow (with our area in the
favored left exit region) which will further enhance convection
into the evening. In addition, southeasterly flow in the lower
levels will continue to transport higher moisture into the
southern half of the district, with PW values approaching one inch
into Kern County. The first threat today will be the possibility
of severe weather this afternoon and evening, especially into
Kern County. MUCAPES of 250-500 J/kg along with decent shear
(Effective Bulk shear 20-25 kts and 0-6km shear near 70kts into
the desert) will help produce stronger organized storm cells later
today, with the primary threat being strong damaging winds. The
other serious impact today will be the risk of very heavy rainfall
and flash flooding, especially into Kern County desert and
mountains. The aforementioned instability, increasing low level
moisture, and local orographic enhancement will produce t-storms
with intense rainfall rates of up to 0.5 inches per hour this
afternoon and evening.

Lastly, winter weather will return to the high elevations of the
Tulare County mountains this afternoon and evening, with 6 to 12
inches of snowfall expected above 7000 feet. General precipitation
totals of 0.5 to 1 inch is expected in the desert, and 1 to 2
inches of precipitation expected into the Kern County mountains.
Although, heavier rainfall totals are possible in stronger
thunderstorms. In the valley, precipitation will be generally
between 0.25 and 0.5 inches from Kings County southward, to 0.1
to 0.25 from Fresno north to Merced county, but with high totals
possible in thunderstorms.

Cutoff low pressure will approach Point conception by Wednesday
morning. This cutoff low will then move due southward over the
course of Wednesday into Thursday morning. As the main cold core
(500mb temps of -25C) of this upper level low moves over the
district, the atmosphere will quickly destabilize late morning
into the afternoon. High-Res Ensemble increases 700-500 mb lapse
rates to 7.0 to 7.5 C/km. When combined with diurnal heating will
be sufficient enough for MUCAPES of 250 to 500 J/kg. With the
absence of any shear, the main threat will primarily be small hail
and locally heavy rainfall, with the greatest risk from Fresno
County southward to Kern County.

The cutoff low pressure then moves due east into northern Baja by
Thursday evening. Our region will experience minor ridging over
the course of Thursday, before the upper level flow becomes
northwesterly on Friday. Moving into the weekend into the end of
the forecast period on Tuesday, deterministic/ensembles all point
to a fairly deep, very cold upper level trough dropping southward
into the western U.S. However, confidence on the position/timing
of this upper level feature is very low, but precipitation looks
to be possible end of the week into the early part of next week.
Of more certainty at this time is that high temperatures will be
far below average from Sunday until the end of the 7 day forecast
period on Tuesday.

&&

.AVIATION...
Areas of IFR in precipitation and mountain obscuration over the
Tehachapis and S Sierra Nevada until at least 18Z Wednesday. MVFR
and local IFR conditions in rain and low clouds will overspread
the San Joaquin Valley and Kern County desert this afternoon into
the evening, eventually clearing by 12Z Wednesday. Thunderstorms
are possible into the Kern Country desert and Southern portions
of the valley until 03Z today. Otherwise, VFR conditions will
prevail the next 24 hours.

&&

.AIR QUALITY ISSUES...
None.

&&

.CERTAINTY...

The level of certainty for days 1 and 2 is high.
The level of certainty for days 3 through 7 is medium.

Certainty levels include low...medium...and high. Please visit
