Area Forecast Discussion National Weather Service San Diego CA 911 AM PST Thu Dec 5 2019

SYNOPSIS. Dry and a little warmer weather returns today 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 and a chance for some occasional light rain. 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 morning, otherwise skies were fair. Surface pressure gradients were weak and winds light. Looks like a nice day shaping up. No forecast changes.

From previous discussion .

The low pressure system that brought the rain yesterday is now centered over Utah and moving east. The lower levels across the area remain moist and winds are light. There have been areas of fog in the high desert and patchy dense fog in portions of the lower deserts. In lower lying portions of coastal and valley areas, there has also been patchy dense fog.

The San Diego River at Fashion Valley had an initial peak at 3 PM yesterday at 8.92 feet and has had a secondary lower peak overnight of 8.39 feet at 12:45 AM. It should continue to fall today and fall below action stage of 7.5 feet around mid morning.

Today will warm slightly with high temperatures Friday a few degrees warmer. For Friday night through the weekend, a closed low pressure system centered off the northern California coast will move slowly toward the coast and weaken. This will draw some subtropical moisture into and across southern California but provide only weak lift. This will generate some light precipitation at times, but with uncertain placement and timing. In general, overall rainfall is expected to be fairly light through Sunday, less than quarter inch for coastal and valley areas and up to around one half inch in the mountains.

For early next week, high pressure will move to near the West Coast with high temperatures warming to near average by Tuesday and Wednesday.

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.
