Area Forecast Discussion National Weather Service San Diego CA 851 PM PST Wed Jan 22 2020

SYNOPSIS. High pressure will continue to build over Southern California through Saturday. Mostly clear skies and warmer than normal temperatures can be expected during this time. On Sunday, a weak system coming in off the Pacific will bring cooler and cloudier weather, as well as a chance of light precipitation through Monday. Warm and dry weather will return on Tuesday as high pressure begins to rebuild.

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

Update:

Mostly clear skies are expected for the rest of this evening into Thursday morning. Weak offshore flow is prevailing across the forecast area. At 8 PM, the pressure gradient from San Diego to Tonopah, NV was -3.9 mb. The offshore flow will likely prevent the formation of low clouds and fog along the coast tonight. High temperatures tomorrow will be about 5 degrees above normal, with temperatures expected to continue to rise through Saturday. The only change made to the forecast this evening was to remove the areas of patchy fog along the coast.

From previous discussion:

The warming trend will continue through Saturday, with Saturday being the warmest day of the week. There could be an increase in high clouds throughout the weekend ahead of a weak Pacific trough.

This weak trough will move inland Sunday and Monday, bringing cooling and a chance for light precipitation. Models and their ensembles are trending weaker with this system, so confidence is fairly high that the region will only see light precipitation. Any precipitation that does fall will be light and not impactful.

Deterministic and ensemble solutions are in good agreement on an even stronger ridge building in from the west on Tuesday, bringing dry weather and a greater warming trend for next week.

AVIATION. 230445Z . Mostly clear skies and unrestricted vis will prevail through Thu evening. Local E/NE surface winds 15-25 knots with gusts to 35 knots will occur along mountain crests and through passes through 22Z Thu.

MARINE. 8-10 ft swells from 290 degrees at 16 seconds will develop south of San Clemente Island this weekend. Otherwise, no hazardous marine conditions are expected through Monday.

BEACHES. The WNW swell from 290 degrees with a 15 second period will gradually diminish through Thursday. A few sets around 6 feet could occur through early Thursday in southern San Diego County and northern Orange County, and strong rip currents and hazardous swimming conditions will continue in those locations through Thursday.

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

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

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.
