Area Forecast Discussion National Weather Service San Diego CA 210 PM PST Thu Dec 5 2019

SYNOPSIS. Dry and a little warmer weather continues through Friday as a weak ridge drifts east across the State. For the upcoming weekend, a moist flow off the Pacific will bring more clouds, slight cooling, and a chance for some occasional light rain. A large west swell may bring high surf to our beaches this weekend. For early next week, a stronger ridge aloft will bring fair and warmer weather.

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

Some patchy high clouds were drifting over SoCal this afternoon with a solid temp recovery in many areas. Some patchy cumulus clouds were near the mountains. Some patchy marine clouds could develop overnight, along with some patchy radiation fog, otherwise it should remain fair tonight. Surface pressure gradients were weak and winds light.

A weak ridge over CA today will drift slowly east on Friday as a low pressure center wraps up 500-600 miles off of Cape Mendocino. The low will weaken and drift east into NoCal this weekend as a weak moist stream with embedded disturbances approaches and moves east over SoCal. With little lift and instability, this event may be largely orographic due to moderate upslope flow on the coastal slopes. The weakened system from the north sweeps through on Monday, gradually clearing out the moisture. Some upslope spots on the San Bernardino Mts could see an inch or more total through the weekend, but most areas look to be well below one inch. Lower elevations are currently projected at mostly one-quarter inch or less total this weekend so only minor runoff expected.

Fair with a warming trend beginning on Tuesday, with high pressure aloft in control through the week. The following weekend could be quite warm with daytime temperatures well above average.

AVIATION. 052000Z . Coasts/Valleys/ . SCT-BKN low clouds with bases around 3000 ft MSL this afternoon. Otherwise, SCT 3000-5000 feet MSL with unrestricted vis through tonight.

Mountains . Coastal slopes obscured above 3000 feet MSL in some areas with fog reducing vis to 1-3 miles at times. Otherwise, SCT 25000 feet MSL with unrestricted vis through tonight.

MARINE. Isolated to scattered showers Saturday and Sunday. Combined seas may rise to around 9 feet Saturday evening into Sunday morning. Otherwise, no hazardous marine weather is forecast through Monday.

BEACHES. A new swell from the WNW will arrive and build on Saturday. Surf up to 8 feet will be possible. The swell and surf will peak late Saturday and early Sunday before subsiding Sunday night. Stay tuned to the Surf Zone Forecast along with any hazard statements that may be issued.

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. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
