Synopsis
The dry and mild spring weather will persist through Tuesday, along
with increasing high clouds as a low pressure trough moves inland to
the north. Onshore flow will increase Wednesday, spreading cooling
inland, along with a small chance of scattered, light showers. An
approaching ridge will begin a warming trend on Friday, that will
carry us through the weekend, along with plenty of sunshine each day.

Discussion For extreme southwestern california including orange...

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

it was mostly clear across socal midday. Surface pressure gradients
were weak and winds mostly light. Satellite imagery showed a band of
clouds advancing slowly SE into the san francisco bay area, but well
offshore farther to the south.

A weak ridge aloft will move east tonight as low pressure off the
pacnw coast drifts slowly east. Precipitation associated with the
storm system will spread SE across northern and central parts of the
state through Wednesday, possibly reaching socal Wed night thu
morning. For now, any amounts look very light as onshore flow ramps
up and the marine layer spreads clouds and fog back onto the coastal
mtn slopes.

The 12z global model runs show fair agreement now in weakening the
low as it slides inland beneath the strong west canadian ridge this
coming weekend. This in tern, has increased confidence in keeping
the weekend dry and mild with little impactful weather expected. The
gfs keeps the weather dry early next week, but the ECMWF turns wet.

This is beyond the current forecast period so we will have some time
to sort it out.

Today looks to be the warmest day of the week, with only slight
cooling on Tuesday. Wednesday and Thursday will be the coolest days,
along with gusty winds over the mts and deserts. Daytime temps
should be about average by Friday, then back above by a few degrees
over the weekend. A wind advisory may be needed at some point for
the gusty onshore winds late Wed thu.

Aviation
251915z... Coast valleys... Clear skies will prevail for the rest of
today and tonight. Low confidence that patchy and intermittent low
clouds could redevelop after 05z tonight 1500 ft msl and below at
ksan, kcrq, and ksna.

Mountains deserts... Clear skies expected through tomorrow.

Marine
No hazardous marine weather is expected today and Tuesday. There is
a slight chance of isolated showers late Wednesday into Thursday,
rain is not expected to be significant. A passing storm system will
bring northwest winds of 12-15 kts with gusts to 20 kts Thursday
evening. These conditions may be hazardous for small craft.

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