Area Forecast Discussion National Weather Service San Diego CA 226 AM PST Wed Dec 11 2019

SYNOPSIS. Building high pressure will bring dry, mild weather through Friday. Thursday and Friday will be the warmest days. A weak trough moving over Southern California this weekend will bring cooler weather along with gusty winds in the mountains and deserts. Offshore flow and higher pressure will bring some northeast winds Monday and a warming trend.

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

High clouds are exiting stage right this morning as patchy low clouds appear and disappear intermittently near the coast. We are looking at fair weather this upcoming week, but with a variety of trends in clouds and breezes. A weak shortwave trough moving through the state this morning will be followed by a high pressure ridge over California. That will warm our air mass some, enough to boost high temperatures 5-10 degrees above average Thursday and Friday. A mix of patchy high and patchy low clouds will continue. The jet stream drops southward this weekend, breaking down the ridge and energizing the westerly onshore flow. It will be much cooler this weekend as a result. Increased humidity will generate some clouds from the coast to the mountains. There are hints of very light precipitation Saturday evening, but not enough to forecast showers yet. The main impact from this trough will be strong winds in the mountains and deserts with gusts that could peak over 50 mph in spots. Some offshore flow gets started Sunday and peaks Monday morning, but recent guidance has dialed back the strength of offshore winds. Current estimates are for top gusts reaching around 35 mph in the wind- prone foothills. High pressure aloft builds a bit, making for a modest warming trend next week with high temps inching above average. After a dry nine days or so, there is some guidance showing the next Pacific trough drawing moisture from the southwest for precipitation next Wednesday or Thursday, but there is little model consensus or consistency in that solution.

AVIATION. 110945Z . Coastal areas . SCT-BKN low clouds at times through 16Z with bases 700-1000 ft MSL. Any cigs at coastal airports will be brief.

Otherwise, SCT-BKN clouds above 20000 ft MSL through Wed night with mostly unrestricted vis.

MARINE. No hazardous marine weather is expected through Thursday. A large, long period west-northwest swell will create combined seas of 8 to 11 ft Friday through Sunday. This could create hazardous boating conditions. West-northwest winds will increase over the outer coastal waters Saturday through Sunday with gusts of 25 kt possible.

BEACHES. A west northwest swell with a period of 16-17 seconds will bring elevated to high surf and strong rip currents to the beaches Friday through Sunday. Current projections are for 5-7 foot surf with local sets to 8 feet, especially in southern San Diego County. Swell periods are likely to be in the 16-17 second range. A Beach Hazards Statement is in effect from 10 AM Friday through 4 PM Sunday.

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

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