Synopsis
For this afternoon through Thursday night, another cold low
pressure system from the north will bring showers with low snow
levels. Heavy snowfall is possible in the mountains. Snow showers
may linger near the mountains on Friday. There will also be
stronger and gusty southwest to west winds in the mountains and
deserts for this afternoon into tonight. Saturday through
Wednesday will be dry with a warming trend with high temperatures
returning to around average by mid week.

Discussion For extreme southwestern california including orange...

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

at 9 am, water vapor satellite showed an upper-level trough racing
south across central ca, with an upper-level low over eastern
washington. Temperatures are on the rise this morning, therefore
the frost advisory was allowed to expire at 9 am. The trough will
move across the region later today through tonight, with the low
diving south and being positioned over southern ca by Thursday
afternoon. This will create showers across most of the region this
afternoon and overnight, then the majority of showers Thursday
look to be mostly over san diego county. H500 temperatures near
-32 c could create a thunderstorm or two across the area Thursday.

In orange and southwestern san bernardino counties, rainfall
could range from 0.25-0.50 inch for the coast and valleys to 1 to
1.5 inches in the mountains. In san diego and western riverside
counties, rainfall could range from around 0.50 inch near the
coast to 1 to 2 inches in the mountains with locally greater
amounts. Amounts in the deserts will mostly be 0.10-0.25 inch.

Amounts could be locally higher in thunderstorms.

The snow level will rise to 4000 to 4500 feet for late this
afternoon, then lower to 2500 to 3500 feet for tonight through
Thursday, lowering to 2000 to 2500 feet for Thursday night. The
lower end of the snow level ranges will be in the san bernardino
county mountains with the higher end in san diego county. In the
mountains, snowfall of 2 to 4 inches is expected down to 3500 to
4000 feet, with 4 to 8 inches from 4000 to 5000 feet, 6 to 12
inches from 5000 to 6500 feet, with local amounts to around 20
inches on the higher peaks. A few snow showers could linger near
the mountains into Friday. A trace to around 1 inch of snow is
expected over the high desert, with local areas around 2 inches.

A winter storm warning remains in effect from 1 pm this afternoon
through 1 am Friday for heavy snow and west to southwest wind
gusts of 50-60 mph for the mountains. A wind advisory remains in
effect for the high deserts through midnight for wind gusts to 50
mph.

Low pressure aloft will finally weaken across the area with dry
weather and a warming trend for Saturday through Tuesday. The gfs
is slower with the warming, but with high temperatures still
returning to near average by Wednesday. The ECMWF has high
pressure aloft near the west coast for early next week with
faster warmer for early next week.

Aviation
201700z... Gradually increasing low clouds today with bases 3000-5000

to 9000 feet in -shra this afternoon and evening. Occasional vis
restrictions 2-4 sm possible in heavier showers after 00z and
through Thursday.

Sw to W winds will strengthen over the mountains and deserts this
afternoon and evening. Surface gusts 40-50 kt, stg uddfs, llws, and
rotors likely over and NE E of the mountains.

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.
