COUNTIES...

...Updated Aviation Section...

This weekend...

A longwave trough located over the entire CONUS is allowing for
another upper level low to drop down over California throughout the
day, and then pass to the south as it propagates eastward and opens
back up to become absorbed back into the trough. As there still
remains to be a decent amount of saturation in the lower levels up
to the 700 mb level, the added lift will allow for the cooler
temperatures to persist, and also allow for there to be a slight
chance of light rain and/or drizzle to be possible this morning,
especially for the foothills of San Diego and Orange counties. There
could also be some patchy areas of fog for some of the coastal and
inland locations. By later in the day, snow levels will continue to
drop to around 5500-6500 ft due to colder air advection from the
north, which may allow for a dusting of snow later this evening for
Mt Laguna, and the surrounding areas. This trough will also allow
for the surface pressure gradient to tighten and bring about some
stronger and gusty winds across the higher terrain by later this
afternoon, and then weaken overnight into tomorrow, with gusts up to
around 45-50 mph possible along some of the foothills and through
the passes. Drier conditions will also set in tomorrow as the
trough begins to flatten and shift further eastward. Winds will
continue to turn more easterly tomorrow weak downsloping offshore
winds will result in high temperatures being about 3 to 5 degrees
warmer from where they will be today.

Monday through Friday...

Drier conditions and a gradual warming trend will occur from the
beginning through mid part of next week as a positivitely-tilted
ridge begins to build in over the Great Basin. Some of the
deterministic models are hinting at the probability of an area of
low pressure possibly influencing the region towards the end of the
week, although this is still quite far out in the forecast period,
and therefore is subject to change. The marine layer will likely
struggle to reform overnight and move inland during the early part
of next week with weak offshore winds, although once the winds
switch back to being onshore by later in the week, the marine layer
will also become subsequently more persistent through the early
morning hours.
