Area Forecast Discussion National Weather Service San Diego CA 151 PM PST Mon Dec 9 2019

SYNOPSIS. Fair and warmer weather is expected this work week as high pressure and weak offshore flow take hold of the region. The upper ridge will build over the area through Friday, resulting in warming conditions. A weak trough will move over Southern California this weekend. While no precipiation is anticipated, it will bring cooling. A weak ridge will likely build early next week, followed by a potentially stormier period during the second half of next week.

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

Highlights.

* Dry week ahead; Warming through Friday, then a cooler weekend * Tranquil start next week; Possibly turning wet late next week

The rest of the week will feature upper level high pressure dominating, which means dry weather and warmer temperatures, especially late this work week. Storm systems will be passing us by to the north with some high clouds reaching us from time to time, including tomorrow afternoon/evening. Still, SoCal will get our fill of sunshine and warmer temps this week, allowing some green up after the nice rainfall we have seen over the past several weeks!

GEFS and ECMWF ensemble means shows H5 height anomalies building through the week, peaking on Friday. Then, a shortwave (inside slider) dives south-southeast which knocks the ridge down. This does not look to provide any rain to the area with NBM POPS 5% of less. However, after warming temps through Friday, cooling will occur over the weekend associated with this feature.

GFS and ECMWF ensemble mean both show transitory ridging early next week followed by a more established U.S. West Coast trough for the end of next week as we head towards Christimas time. CPC does indeed highlight a favored wetter pattern developing in the Dec 17-23 timeframe. It is during this period when additional Pacific storms could impact Southern California. Something to watch on the horizon.

AVIATION. 092100Z . Coasts/Valleys . SCT-BKN clouds with bases 2000-2500 ft MSL gradually clearing after 00Z. Low clouds may redevelop after 10/08Z with bases near 1500-2000 ft MSL and spread 10-15 mi inland through 16Z, but confidence is too low to include in the TAFs. Otherwise increasing high clouds Tuesday afternoon and unrestricted vis.

Mountains/Deserts . Mostly clear through Tuesday morning, with increasing high clouds Tuesday afternoon. Vis remaining unrestricted.

MARINE. No hazardous marine weather is expected through Friday.

BEACHES. Elevated surf pf 3-5 ft and strong rip currents today as the west- northwest swell continues to fade. Another large, long period west- northwest swell is forecast to arrive this weekend, bringing another round of elevated to high surf and strong rip currents.

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.
