Area Forecast Discussion National Weather Service San Diego CA 200 PM PDT Mon Sep 21 2020

SYNOPSIS. Fair weather will prevail this week. Areas of low clouds and fog will occur at times during the nights and mornings near the coast. Some gusty southwest to west winds will occur in the mountains and deserts through Tuesday night. Temperatures will mostly be mild Tuesday, but some warming will occur again over inland areas Wednesday and Thursday. Some cooling will occur Friday and Saturday, but then offshore flow under a building high pressure ridge will bring more warming next Sunday along with locally gusty east winds and low humidity. Autumn officially starts at 631 AM PDT Tuesday.

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

Skies were mostly sunny over the region, except for shallow cumulus over the mountains and a few patches of stratus at the beaches. Temperatures were mostly seasonal over the region. Stratus was over the coastal waters, and like Sunday afternoon, were moving east, indicating our onshore flow pattern. We should have stratus and patchy fog in similar areas tonight and early Tuesday that happened last night and this morning.

We will have a couple of troughs moving by to the north this week, though nothing too strong. The first will move by Tuesday with the second around Friday, with a moderate high pressure system over our area Wednesday/Thursday. That will result in the temperature fluctuations--milder with the trough Tue/Fri/Sat and increased west/southwest flow in the mountains/deserts and warmer Wed/Thu, with some highs in the upper 90s in the Inland Empire, even locally 100.

A pattern change will happen around Sunday as an upper high moves over the West Coast, and surface offshore flow develops. This looks like more of an easterly flow versus northerly flow, so most of the gusty east winds will occur on the west slopes in San Diego and Riverside Counties and through Banning/San Gorgonio Pass. Temperatures will be quite warm with near 100 possible west of the mountains again, and humidity will be low, around 10 percent in some valleys possible. That upper high could get strong over the western US early next week based on ensemble projections.

AVIATION. 212000Z . Coast/Valleys . Stratus to develop after 01z Tue across coastal sites and will spread 15-20 miles inland after 03z Tue. Bases to drop to 600-1000 FT MSL. Fog will be possible where clouds intersect with terrain, vis 1-4 miles. Stratus to diminish after 16z Tue inland, and between 16z-18z Tue across coastal areas.

Mountains/Deserts . Clear with unrestricted vis (VFR) through Tue. Surface gusts to develop after 21z Mon with west to southwest wind gusts to 25-35 kts. This may lead to moderate updrafts and downdrafts. Winds to diminish after 02z Tue.

MARINE. No hazardous marine conditions through Saturday.

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

SGX WATCHES/WARNINGS/ADVISORIES. CA . NONE. PZ . NONE.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
