Synopsis 25 733 pm.

A low pressure system will bring increasing clouds and showers to
the area late tonight through Sunday. Isolated thunderstorms are
expected for interior areas Sunday afternoon and evening, along
with a chance of mountain snow. Warming and drying is expected
early next week.

Short term (sat-tue) 25 817 pm.

***update***
busy afternoon in the mtns as a little trof went over the region
and interacted with the usual area of instability over the
northern vta county mtns produced two large near severe tstms.

These two tstms moved to the nne into kern county where they all
merged with a very strong TSTM that formed there. The resultant
tstm then moved to SE following the path of the very strong kern
county tstm. This storm advected into NRN la county mtns near the
grapevine bringing lightning and brief heavy downpours along with
it. The trof has moved to the east and the Sun has set both of
which combined to end the TSTM threat for the night.

Moderate onshore flow kept the marine layer stratus over the
central coast all day long. There was good clearing early this
afternoon over the coasts and vlys south of pt conception but low
clouds are already rapidly filling into the area and by early
morning Sunday low clouds should cover almost all of the coastal
and vly areas. An unseasonably cold upper low will also dive down
through the state overnight and the lowering hgts and weak
peripheral lift will bring drizzle or light rain to many areas
across the coasts and vlys as well as the coastal slopes.

00z runs still show that the unusual Sunday forecast is on track
with the upper low bringing widespread rain to the entire area.

Snow down to 5000 feet (locally 4500 feet) and afternoon and
evening tstms near the kern county line.

There will be enough snow and rain with the system to create a
multitude of winter weather problems and a winter weather advisory
is in effect from 600 am Sunday morning through late Sunday
evening.

***from previous discussion***
a rather potent upper level low pressure system for this time of
year (as low as 543 dm at h5) is forecast to move to the far NRN ca
coast by late tonight then SE into central ca on sun. This system
will continue tracking SE into sern ca Sun night then E into NRN az
on mon. A broad NW flow aloft will be over SRN ca Mon night. A fast-
moving and weak upper level disturbance should move into swrn ca
from the N on tue. The upper level low will quickly lower h5
heights and bring in colder air aloft thru Sun afternoon, down to
-20 deg c over NRN l.A. County to as low as - 26 deg c for NRN slo
county. The 12z NAM does not indicate much instability over the
fcst area on Sun likely due to cloud cover, but surface-based lis
were still 0 to -2 over portions of the mtns to NRN slo county in
the afternoon. The area will also be under the left exit region of
a 120 kt jet Sun afternoon. Altho the nam MOS was showing a
slight chance of thunderstorms over a large portion of swrn ca,
for now will keep a slight chance of thunderstorms over the mtns,
antelope vly, cuyama vly and interior slo county vlys for sun
afternoon and early evening. Otherwise, showers and mountain snow
showers will be likely across most of the fcst area thru sun
afternoon, with decreasing showers Sun evening.

Rainfall totals are expected to generally be under 0.10 to 0.25 inch
for the coast and vlys, except up to 0.50 inch in some foothill
areas, and 0.25 to 0.75 inch in the mtns with local amounts up to
1.00 inch possible. Snow levels will fall to 6000 to 6500 feet on
Sunday, then drop further to 4500 to 5500 feet Sunday night, with
accumulating snow expected over a wide area above 5000 to 5500 feet.

It looks like up to 1 inch of snow will be possible below 5500 feet,
with about 2 to 4 inches between 6000 and 6500 feet, and about 3 to
6 inches with local higher amounts above 6500 feet. The highest
peaks may see accumulations up to 8 or 9 inches.

Gusty mainly sub-advisory level south to west winds will also affect
the mtns, producing reduced visibilities in snow and blowing snow.

Expect wintry driving conditions in the mtns above 5000 to 6000 feet
Sunday into Sunday night, with snow and ice covered roads. These
conditions are more typical in a mid-winter storm. If you plan on
going into the mtns Sunday, be prepared for hazardous driving
conditions and dress for winter weather.

With the unusual winter-like storm expected, a snow advisory has
been issued for the ventura and los angeles county mtns from 6 am
sun thru 3 am Mon for the accumulating snow and gusty winds. Please
see the latest winter weather message (laxwswlox) for further
details.

There will be a slight chance of rain and snow showers thru late sun
night in the mtns, otherwise dry weather can be expected later sun
night thru Mon across the region. Decreasing cloudiness can also be
expected thru mon, with a fair amount of sunshine for Mon afternoon.

Marine layer clouds and fog are forecast to return to much of the
coast and vlys Mon night into Tue morning, otherwise mostly clear
skies can be expected thru Tue with breezy onshore winds tue
afternoon.

Temps will be well below normal in all areas on sun, as much as 15-
25 deg or more below seasonal norms. It will be so chilly on sun
that many climate stations will likely have near record to record
cold high temps for that date. For example, the lowest MAX temp
recorded for may 26th at downtown l.A. Is 63 deg set in 1947 while
the fcst MAX temp on Sun there is 61 deg. Temps for Mon will turn
warmer but still be at least 5-15 deg below normal for many areas.

Highs will turn much warmer on Tue but remain 3-7 deg below normal
overall.

Long term (wed-sat) 25 218 pm.

The ec and GFS are in generally good agreement in the extended
period. Another weak upper level trof will move into the forecast
area on wed, then broad upper level troffiness will persist over
the region Thu thru sat.

There will be a slight chance of showers in the mtns in the
afternoon and early evening Wed and thu, with a small chance of a
thunderstorm (less than 15%). Otherwise, clear to partly cloudy
skies with varying amounts of night and morning low clouds and fog
for the coast and vlys can be expected. Temps will have minor day-to-
day changes thru the extended period, but overall remain several
degrees below seasonal norms.
