.SYNOPSIS...
A low pressure system from the northwest will deepen the marine
layer into Wednesday and bring a chance of showers for the
mountains, deserts, and inland valleys for Tuesday afternoon
through Wednesday afternoon along with a chance of thunderstorms
for Tuesday afternoon and evening and again for Wednesday
afternoon. It will be dry and gradually warmer for Thursday
through next weekend with high temperatures warming from a few to
around 5 degrees below average on Thuesday to around 5 degrees
above average for next weekend. The marine layer will become
gradually shallower for the latter half of the week with night and
morning coastal low clouds not spreading as far into the valleys.
&&
.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...
.SHORT TERM (Today through Wednesday)...
An upper level low pressure system centered over southwest Arizona
early this morning will move east and weaken today. A second low
pressure system will move southward off the California today, then
move slowly eastward off the southern California coast on Tuesday,
and then inland across southern California and northern Baja for
Tuesday night and Wednesday.
The higher precipitable water values across the area on Sunday
won`t decrease all that much today, but the atmosphere will be
more stable. Precipitable water values will increase again on
Tuesday, similar to those of Sunday, before gradually decreasing
for the rest of the week. That low pressure system from the
northwest will draw more moisture into the area from the south on
Tuesday and increase the instability for Tuesday into Wednesday.
There is a chance of showers for the mountains, deserts, and
inland valleys for Tuesday afternoon through Wednesday afternoon
along with chance of thunderstorms for Tuesday afternoon and
evening and again for Wednesday afternoon.
A marine layer near 2000 feet deep will deepen for Tuesday into
Wednesday to around 3500 feet for Tuesday night into Wednesday
morning with coastal low clouds extending well inland and onto the
lower coastal mountain slopes.
High temperatures will generally slowly cool through Wednesday
with Wednesday high temperatures a few to around 5 degrees below
average. High temperatures for Wednesday will range from the upper
60s near the coast to the mid 70s to lower 80s for the Inland
Empire with the mid to upper 90s for the lower deserts.
&&
.LONG TERM (Thursday through Sunday)...
Low pressure aloft will weaken for Thursday and Friday with high
pressure aloft strengthening for next weekend. It will be dry with
a gradual warming trend with high temperatures warming from a few
to around 5 degrees below average on Thursday to around 5 degrees
above average for next weekend. With the warming, high
temperatures for next weekend will range from around 70 near the
coast to the mid 80s to lower 90s for the Inland Empire with 104
to 108 for the lower deserts.
The greater spread in the high temperature guidance is for the
valleys due to uncertainty in the marine layer depth. The marine
layer will become gradually shallower for Thursday into next
weekend with night and morning coastal low clouds not spreading as
far into the valleys.
&&
.AVIATION...
020930Z...Coasts/Valleys...Low clouds based at around 1000 feet MSL
with tops to 1800 feet will gradually fill coastal areas and
westernmost valleys by 14Z. Vis reduced over higher coastal terrain.
Scatter out by 16-17Z, but patches may linger along immediate coast
thereafter. Low clouds will push ashore after 02Z and head into
inland valleys overnight into Tuesday. Bases will be closer to 1500
feet MSL, with vis reduced inland.
Otherwise...SCT-BKN clouds near 10000-15000 feet MSL will gradually
drift east this morning. Cumulus clouds based at 9000 feet MSL to
form over mountains and locally over deserts 18-02Z.
&&
.MARINE...
No hazardous marine conditions are expected today through Friday.
&&
.BEACHES...
A long period south swell will bring elevated surf up to 6 feet to
the region, especially to south and southwest facing beaches,
through Tuesday, resulting in a higher rip current risk and locally
hazardous swimming conditions. A Beach Hazard Statement is in effect
and contains more information.
&&
.SKYWARN...

encouraged to report significant weather conditions.
