Area Forecast Discussion
National Weather Service San Joaquin Valley - Hanford CA
411 AM PDT Sat May 25 2019

.SYNOPSIS...A low pressure system will bring an increased chance
of showers and thunderstorms over our area today, and especially
on Sunday. Some thunderstorms could become strong with small hail,
gusty winds, and locally heavy rainfall possible. Several inches
of snowfall is forecast over parts of the Sierra Nevada.
Temperatureswill become significantly cooler on Sunday. A
warming trend is expected next week with a few afternoon and
evening showers possible over the Sierra Nevada each day. &&

.DISCUSSION...Shortwave energy dropping out of the Pacific
Northwest will track across central CA today and will bring a
chance for some showers and a few thunderstorms over much of our
area this afternoon and evening. Temperatures will be slightly
warmer across much of the area but still running a few degrees
below climo.

A more significant developing low pressure system is progged to
follow behind the shortwave trough and is expected to swing
across central CA on Sunday. This system will have more
associated moisture and is forecast to bring as much as 4-8 inches
of snow over the higher elevations of the Sierra Nevada. This
relatively cold system will lower snow levels to around 6000 ft
and will bring a significant change in weather conditions. The
additional incoming snowfall will cause travel impacts in the
Sierra above 6000 ft and a Winter Weather Advisory has been issued
for there from 5 AM Sunday through 5 AM Monday.

The storm system will also bring significant weather to the lower
elevations in our area. As the system pushes in early Sunday,
precipitation will spread southward across our area. The upper low
will track overhead and will help to destabilize the airmass,
providing a chance for thunderstorms over most of the area Sunday
afternoon and evening. The storms could become strong with heavy
downpours and some hail. QPF ranges from around 1 to 3 tenths of
an inch in the SJ Valley to around 4 to 6 tenths in the
foothills. Desert locales are expected to generally see a few
hundredths to around 1/10 of an inch. Temperatures Sunday will
also be much lower, with highs around 15 to 20 degrees lower than
on Saturday. The passing system will also bring gusty winds Sunday
afternoon and evening, especially through and below mountain
passes.

The low pressure system is progged to swing eastward toward the
Four Corners region Monday with just some lingering Sierra
convection possible. Models suggest additional shortwave energy
will keep us in a general troughy pattern throughout next week.
This will maintain chances for mainly mountain convection each
afternoon and evening through the end of the week. Temperatures
will slowly moderate, and should just reach around normal for this
time of year by next weekend.

&&

.AVIATION...
Scattered showers and a few thunderstorms are expected this
afternoon. Local IFR conditions in storm showers after
20z Sat. Otherwise VFR conditions will prevail elsewhere over the
central California interior during 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
