Synopsis
A large-scale trough over western North America will persist through this week. Temperatures will remain below seasonal averages with gusty winds across the mountains and deserts. A closed upper level low will move across the region on Monday, which will bring the coolest and windiest conditions overall. Low clouds will continue nigheights and mornings, retreating back to the coast each afternoon.

For Extreme Southwestern California Including Orange... San Diego...Western Riverside and Southwestern San Bernardino Counties
The marine layer continues to gradually fill the coastal basin with low clouds this morning. A weak trough of low pressure to the west will get picked up by a larger jet stream-driven trough to the north this morning and push through SoCal today. This should deepen the marine layer and produce patchy drizzle this morning, most likely near the coast. Winds through mountain passes into adjacent deserts will continue strong and gusty through this evening, with isolated top gusts through San Gorgonio Pass exceeding 50 mph, but more widespread gusts of 35-45 mph. As the trough exits east, the trend will be to decrease the onshore flow and tamp down the marine layer a little. That should bring more sunshine west of the mountains and weaker winds in the mountains and deserts for Tuesday and Wednesday. High temperatures in the 60s to low 70s west of the mountains today represent up to 10 degrees below normal in the valleys. Tuesday and Wednesday will be a few degrees higher, approaching but still not achieving normal. A very weak trough rotates through California again Thursday into Saturday. This should deepen the marine layer again and extend low clouds into foothills each night and morning, and make it harder for coastal areas to get sunshine in the afternoons. This will also boost those seasonal winds in the mountains and deserts. The cooler weather starts Thursday, and right now appears to bottom out Saturday, when temps will be more than 10 degrees below normal in the valleys. Next week the mean trough over the West appears to weaken, maybe making way for an actual ridge of high pressure. While ensembles paint a wide range of outcomes, most solutions indicate at least weaker low pressure and warmer weather next week.

Marine
No hazardous marine conditions are expected through Friday.

Beaches
A series of southwest swells of 2-3 ft at 16-18 seconds from 200-220 degrees will build through Monday and produce above normal surf of 3- 5 ft with locally higher sets on exposed SW facing beaches, as well as a high risk of rip currents at all beaches. A Beach Hazards Statement is in effect through this evening. Swell and surf will slowly lower Wednesday and Thursday.

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