930 pm pst Tue feb 19 2019

Synopsis
Dry weather will continue through Wednesday morning with a cold
night tonight and areas of frost in the valleys and lower deserts.

From Wednesday afternoon through Thursday night, another cold low
pressure system from the north will bring showers with low snow
levels and strong and gusty westerly winds in the mountains and
deserts. Heavy snowfall is possible in the mountains. Dry and a
little warmer weather will occur this weekend. Small chances of
light precipitation could return for Sunday night and Monday.

Discussion For extreme southwestern california including orange...

san diego... Western riverside and southwestern san bernardino
counties...

forecast looks on track with the next system currently elongated
from SE alaska to off the washington coast but clear dry conditions
over so-cal. Winds were mostly light this evening, and temperatures
were generally near or slightly warmer than 24 hours ago, so more
frost is expected in the valleys and lower deserts overnight. Model
guidance continues to place the beginning of light precipitation
around or a little below noon Wednesday with more substantial
precipitation developing late Wednesday afternoon and evening. More
details are in the previous afd below, but best precipitaiton will
be in san diego county due to the better over-the-water trajectory,
with enough northwesterly flow for lighter precipitation to occur
farther north. Substantial snow in the mountains is most likely from
big bear south through the riverside county and san diego county
mountains, with heaviest snow Thursday when the 700-500 mb layer
will be mostly saturated and below -10 c for dendritic snow crystal
growth. Right now, it looks like precipitation should mostly end
Thursday night. Don't look for warm weather anytime soon as
temperatures will remain below normal through next Tuesday, with
next Wednesday (feb 27) being the first possibility of temperatures
at seasonal normals.

From previous discussion...

a cold, upper-level low will dive down across the west mid to late
this week, with precipitation developing across our area by
Wednesday afternoon and continuing through early Friday.

Preliminary precipitation amounts are 0.10-0.20 inches in the
deserts, 0.10-0.50 inches for coastal orange county and the
inland empire, 0.50-0.75 inches for the san diego county coast and
santa ana mountains, 0.75-1.50 inches for the san diego county
valleys and the riverside san bernardino county mountains and
1.50-2.00 inches for the san diego county mountains. Isolated
thunderstorms are possible Thursday as the cold airmass moves into
place, which could create locally higher precipiation where
storms develop.

Snow levels will be quite low, ranging from 3000-3500 ft
Wednesday, to 1500-2500 ft Thursday and 1000-2000 ft Friday
morning, with lowest levels in san bernardino county and highest
in san diego county. Total snow accumulations of 1-3 inches from
2500-3500 ft, 3-5 inches from 3500-4500 ft, 5-10 inches from
4500-5500 ft and 12-16 inches above 5500 ft, with localized
amounts up to 20 inches, are expected. A winter storm warning has
been issued for the mountains from 1 pm Wednesday through 1 am
Friday for heavy snow and gusty winds. Snow may be more
infrequent Thursday afternoon for the san bernardino county
mountains. A dusting is possible down to 2000 ft in the mountains,
with a dusting to around an inch is possible in the high deserts.

The cajon, san gorgonio and i-8 mountain passes are likely to be
affected by accumulating snow, which would create travels hazards
during the period. Westerly wind gusts of 50-60 mph are also
expected across the mountains into adjacent deserts as the system
moves across the area, mainly affecting san diego and riverside
counties. A wind advisory has been issued for the high deserts
from 10 am Wednesday through midnight.

Dry and cool weather will develop over the weekend, with a small
chance of light precipitation Monday morning as a system moves by
to our north. High temperatures will remain below normal into
early next week.

Aviation
200430z... Mostly clear with unrestricted vis through Wednesday
morning. Increasing sct-bkn cloud layers with bases 3000-5000 ft msl
late Wednesday morning, lowering to around 1500-2500 ft msl with
tops to 9000 ft msl in -shra Wednesday afternoon and evening. Local
vis 3-5 sm possible in heavier showers, mainly after 21 00z.

Sw to W winds will strengthen over the mountains and deserts
Wednesday afternoon and evening. Surface gusts 30-45 kt, stg uddfs,
llws, and rotors likely over and NE E of the mountains.

Marine
West-northwest winds and seas will increase Wednesday afternoon as
the next storm moves in, leading to hazardous boating conditions.

Winds 15 to 20 kt with gusts 25 to 30 kt and combined seas up to 10
feet will continue into Thursday night before diminishing. There is
also a slight chance of thunderstorms Thursday afternoon. A small
craft advisory is in effect for the coastal waters from 1 pm
Wednesday through 10 pm Thursday.

encouraged to report significant weather conditions.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
