.SYNOPSIS...
High pressure will strengthen over the area by the middle of the
week, leading to hotter weather for inland areas. The marine layer
will become shallower, leading to low clouds and patchy fog near
the coast each night and morning. The high pressure will weaken
slightly, keeping the deserts slightly warmer than average and
closer to average elsewhere.

&&

.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...

Our area continues to be sandwiched in between low pressure off the
Central Coast and high pressure NW Mexico (Sonora, Chihuahua).
This continues to keep us right near average for this time of year
with elevated onshore winds across mountain passes and adjacent
deserts 20-35 mph. The area of low pressure will stick around one
more day where the marine layer will be fairly similar to what it
was this morning with far western valleys and coastal areas seeing
low clouds and fog. The high pressure system over Mexico will
strengthen into Tuesday, causing the marine layer to become
shallower and keep clouds/fog confined closer to the coast. As the
high provides greater influence over the region, we can expect
temperatures for inland areas to nudge up a couple degrees. Lower
level moisture will also creep into SoCal, where higher humidity
will be felt Tuesday through Thursday.

Models show the high continuing to amplify on Wednesday and Thursday
as it moves over our region. This will lead to the hottest
temperatures of the week with highs reaching near 5 to 10 degrees
above normal. Confidence on highs reaching 115 are moderate as
influxes of low level moisture can make for a tricky high
temperature forecast; though whatever the outcome, it will feel
hotter and humid by the middle of the week. Please take extra
precautions if you must be outside for long periods or do not have
adequate cooling/hydration methods. As the high peaks in strength,
high temperatures have a moderate to high chance of reaching 100
degrees across the Inland Empire and high desert. Widespread 90s are
in the forecast for inland valleys of Orange and San Diego counties,
though some spots in the SD co valleys may reach near 100 degrees.
Make sure to only recreate outdoors in the early mornings or
evenings in the mountains as well, since highs will be in the upper
80s to upper 90s from Idyllwild to Julian.

Models are in fair agreement of the area of high pressure weakening
slightly but staying over our region into next weekended.
This will continue a fairly thinner marine layer with low clouds and
fog closer to the coast. Also if this occurs, most areas will cool
with high temperatures near average except the deserts, which will
stay near 5 degrees above normal.

&&

.AVIATION...
0601930Z....Coast/Valleys..CLear conditions will continue through
the remainder of the daylight hours. Low clouds 900-1400 ft MSL will
reform and move ashore again after 04Z Mon. Local visibility
restrictions will occur where clouds intersect with elevated
terrain. Breakup of the marine layer inversion and associated
stratus deck is expected to occur between 15Z-17Z Monday morning.

Mountains/Deserts...Mostly clear with unrestricted VIS through
Monday.

&&

.MARINE...
No hazardous marine weather conditions are expected through
Wednesday.

&&

.BEACHES...
Southerly swell (190 degrees) of 3 to 4 feet at 14-16 seconds will
generate elevated surf of 4-6 ft with sets to 7 ft along south
facing beaches through Sunday evening. In addition, strong rip and
longshore currents are expected at all beaches through Sunday. A
Beach Hazards Statement is in effect and contains more information.
Surf may remain elevated into early next week.

&&

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