&&

.SHORT TERM (FRI-MON)...22/816 PM.

***UPDATE***

A cold front extending from northern California to the coastal
waters off the Central Coast has an associated rain band that has
been slowly approaching San Luis Obispo County this afternoon and
evening. Rain should begin to spread over the NW Central Coast
area within the next couple of hours (between 800 to 1000 PM)
spreading southwestward across San Luis and Santa Barbara Counties
overnight, and then across Ventura and LA Counties on Saturday.
Gusty southerly winds will accompany the front, with gusts
generally between 20 to 35 mph across the windiest areas,
including the mountains and foothills. North of Pt. Conception the
stronger winds are expected this evening through tonight, then
shifting to areas further south on Saturday, mainly affecting the
mountains and Antelope Valley.

Rainfall totals for tonight through Saturday will be light over LA
County, up to 0.10 inch. For Ventura and Santa Barbara Counties,
totals will be 0.10 to 0.25, with 0.20 to 1.0 inch over San Luis
Obispo County, except for potentially up to 1.5 inches in the
Santa Lucias.

***From Previous Discussion***

The large cyclone off the Pac NW coast has split into two which
are pinwheeling around each other. The southern extent of the
moisture is around Monterey, but that will be sagging south
tonight and through early next week as the main upper low shifts
south to near the OR/CA border. With the upper low remaining that
far north that will limit the impacts and rainfall amounts
locally.

Latest ensembles and hi res models all indicating 3-5 hours of
very light amounts with this first impulse, mostly under a quarter
inch most areas. Locally up to a half inch in the upslope areas
of SLO/SB Counties. For LA County light rain expected to start mid
to late morning with most areas under a tenth of an inch and many
areas may not receive more than a trace.

After that there`s a roughly 24-36 hour break before the second
impulse comes through Sunday (for SLO County) and later Sunday
into Monday south of there. The 12z ENS solutions definitely
ticked up across SLO County, with the precip means between now
between 1 and 1.5 inches. Which means upslope areas in the Santa
Lucias could be looking at around 3" or rain with with this
impulse through Tuesday. The GEFS means remain well under an inch
in all areas so still some uncertainty there. Even with these
slightly higher numbers the chances for any significant flooding
issues remains under 10%.

Amounts drop off quite a bit to the south, and especially south of
Santa Barbara with totals through Tuesday still under 1 inch and
likely under a half inch for most of LA County. No snow and wind
issues expected, though it will be breezy at times, mainly at the
higher elevations.

.LONG TERM (TUE-FRI)...22/155 PM.

Still a possibility of some lingering light showers Wednesday but
the ensembles have basically gone back to a dry pattern the
remainder of the week and through the Thanksgiving weekend. There
are some indications of increasing offshore flow but so far the
ENS ensembles are mostly on the weak to moderate side, which
matches up well with the deterministic LAX-DAG gradients which
are between -4 and -5.5mb while the GFS gradients are weaker.
Temperatures will be on a steady but slow climb each day but
generally remaining slightly below normal through Friday.
