Synopsis
The rest of this afternoon will be sunny with temperatures
continuing to be below normal. High pressure aloft will expand over
the southwest next week and bring warmer weather and less extensive
night and morning coastal low clouds. Moisture from the southeast
and more instability will bring chances of mostly afternoon and
early evening mountain and desert thunderstorms Monday through
Thursday, with best chances Tuesday and Wednesday.

Discussion For extreme southwestern california including orange...

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

sunny skies prevailed this afternoon with temperatures continuing 5-
10 deg f below normal in most areas. Winds were mostly light to
moderate at early afternoon, except for a few locations on the
desert slopes which had gusts over 20 mph, including the white water
raws which had a recent gust of 37 mph.

A large high pressure ridge extends from the mid-atlantic states
west through the central and south-central us to northern baja
california, with a broad trough over the NE pac and NW us. The upper
high will gradually shift towards the southwestern us Sunday and
expand over the west Mon tue. The GFS ensembles have been good with
consistency between members and runs in recent days, with the center
of the upper high likely over the four corners region mon-the. This
is a favorable pattern for monsoonal thunderstorms in the
mountains deserts of socal, and moisture will be abundant during
this time at above 700 mb, with a mostly dry layer below that except
for occasional near-surface moisture surges from the gulf of
california into the lower deserts. Instability will be the key to
thunderstorm development, with best instability likely Tue or wed.

12z GFS is showing capes of 2000-3000 j kg Wed afternoon over many
of our mountain areas with some CAPE along the elsinore convergence
zone in the inland empire where there is a small chance of a
thunderstorm in the afternoon. National blend of models show Wed as
the best day for thunderstorms as well. With total precipitable
water exceeding 1.5 inches in the lower deserts Tue wed, there could
be a risk of flash flooding then as well. West of the mountains, the
stratus should be far less extensive and more patchy Sun night-mid
week, partly due to the greater amount of longwave radiation
reflecting off the mid-level moisture.

Late in the week, the upper high could shift a bit farther west,
though not all models ensemble members agree with this. If the high
shifts west, monsoonal activity should decrease somewhat, and
temperatures should increase a bit, though 850 mb temperatures
mostly just increase in the deserts. Especially with lower humidity
in the deserts late in the week, temperatures should rise to around
110 by then.

Aviation
201950z... Coast valleys...VFR conditions will continue this
afternoon with low clouds returning to the coast after 04z with
bases 1000-1500 ft msl. Vis may be reduced on higher coastal terrain
in areas of low clouds overnight. Low clouds along the coast
expected to scatter out 16-18z Sunday.

Mountains deserts... Skc with unrestricted vis through Sunday.

No hazardous marine weather expected through Thursday.

Skywarn activation is not requested. However weather spotters are
encouraged to report significant weather conditions.
