...THE FLASH FLOOD WARNING REMAINS IN EFFECT UNTIL 145 AM PST FOR
NORTHEASTERN KERN AND SOUTHEASTERN TULARE COUNTIES...

At 1259 AM PST, doppler radar indicated heavy rain across the warned
area.  Although rain rates have fallen to around quarter of an inch
per hour, the likelihood of flash flooding remains.

Excessive rainfall over the burn scar will result in debris flow
moving through the Kern River drainage in the warned area. The debris
flow can consist of rock, mud, vegetation and other loose materials.

Some locations that will experience flooding include...
Wofford Heights, Riverkern and Kernville. 

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Move to higher ground now. Act quickly to protect your life.

Area Forecast Discussion
National Weather Service San Joaquin Valley - Hanford CA
237 PM PST Thu Dec 15 2016

.SYNOPSIS...A strong storm system will move across Central
California through Friday. Moderate to heavy rain and higher
elevation snow along with gusty winds will accompany the storm as
it passes. Much cooler temperatures and drier conditions are
expected Satruday through the middle of next week. Temperatures
will lower to below normal by the end of the week and into the
weekend.

&&

.DISCUSSION...Rain and higher elevation snow pushed into our area
overnight ahead of a strong upper low currently centered well off
the northern Baja coast near 32N/130W. Precipitation totals so far
have generally ranged from 0.50 inches to 0.75 inches of liquid
precipitation in Yosemite National Park with the snow level
currently running around 9000 feet. Further south rainfall amounts
of a quarter to half inch have been common in the Southern Sierra
Nevada between Yosemite Park and Kings Canyon while amounts have
been a tenth of inch of less so far in higher elevations of Tulare
County. Rainfall amounts in the San Joaquin Valley have been
generally light with most locations picking up between a trace and
a tenth of an inch of rain.

Radar composites are showing a band of moderate to heavy
precipitation north of our area. As this band of deep moisture
continues to drift southward this evening as the low approaches it
will be fed additional tropical moisture being pulled up northward
from the offshore low which will result in periods of moderate to
heavy precipitation for our area this evening through Friday
morning. QPF progs are indicating some very impressive rainfall
totals for our area with 4-6 inches of liquid precipitation
expected for much of the Southern Sierra Nevada from Kings Canyon
northward and 2-4 inches of liquid precipitation in the Tulare
County mountains. As a result of the heavy precipitation several
feet of new snow will be possible through Friday in the southern
Sierra Nevada and a Winter Storm Warning remains in effect above
8000 feet through 1000 am PST Friday.

Below 8000 feet, a big concern is with heavy rainfall expected
over burn scarred areas the potential exists for flash flooding in
the mountains and adjacent foothills and a Flash Flood Watch
remains in effect the Southern Sierra Nevada below 8000 feet, the
southern Sierra foothills and the Kern County mountains through
400 pm PST Friday. Moderate to heavy rainfall is also anticipated
for the San Joaquin Valley this evening through Friday morning
with most locations on the west side picking up between half an
inch and an inch of rain while an inch to 1.5 inches of rain is
expected on the eastern side of the valley. The moderate to heavy
rainfall will result in nuisance flooding over San Joaquin Valley
and a Flood Watch remains in effect for the valley through Friday
afternoon. Lesser rainfall amounts are expected in the Kern County
Deserts, but localized street flooding will be possible tonight
through Friday morning.

As the low moves east of our area on Friday a cold front will push
through the area behind it on Friday afternoon resulting in
plummeting snow levels and increased winds. This will adversely
impact travel over the Kern County Mountains and Deserts and as a
result a wind advisory has been issued for the Kern County Deserts
from 1000 am PST Friday through 1000 pm PST Friday where wind gusts
above 50 mph will be possible. A Winter Weather Advisory has been
posted for the Kern County Mountains from 1000 am PST Friday
through 400 am PST Saturday where winds gusts above 50 mph and
light snowfall accumulations over the passes will potentially
make travel difficult.

By Saturday morning the precipitation will taper off and a colder
and drier airmass will settle in over our area. Some upslope low
clouds will persist in the south end of the San Joaquin Valley and
the valley facing slopes of the Tehachapi Mountains on Saturday
morning with skies clearing out by Saturday afternoon. With clear
skies, diminished winds, light winds and a dry airmass in place
there is a potential for a widespread freeze across the San
Joaquin Valley on Sunday morning. Another freeze will be possible
on Monday as the cold and dry airmass remains in place across our
area.

The medium range models and their ensemble means are in good
agreement indicating high pressure will amplify off the CA coast
early next week with dry weather anticipated across our area
through midweek with a slight day to day warming trend. A Pacific
shortwave pushing through the PAC NW on Tuesday Night will provide
for some high clouds and enough mixing to inhibit widespread fog
formation inn the San Joaquin Valley. The models are indicating
the potential for another low pressure system pushing into central
CA by the end of next week with the GFS indicating the northern
portion of our CWFA will have the potential for some precipitation
while the ECMWF is further north.

&&

.AVIATION...MVFR/IFR in ceilings and precipitation across Central
CA through 18z Friday. Mountain obscurations in Sierra
precipitation. VFR in the Kern County desert through 03z becoming
MVFR tonight in ceilings and precipitation.

&&

.AIR QUALITY ISSUES...None.
