Showers will gradually decrease in frequency and coverage today. However, isolated Thunderstorms are possible over the coastal waters this morning. Weak offshore flow develops for Friday through the weekend, producing weak easterly winds nights and mornings and northwest breezes afternoons and evenings.

Area Forecast Discussion National Weather Service San Diego CA 930 AM PST Thu Nov 21 2019

SYNOPSIS. Scattered showers with a slight chance of mainly coastal thunderstorms will occur today, with precipitation ending this evening. Fair weather will return Friday, and there will be a gradual warming trend Friday through Sunday. The fair weather will continue through early next week with a cooling trend beginning Monday, then a trough of low pressure could bring more precipitation Wednesday and Thanksgiving.

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

Scattered showers have mostly been in coastal areas this morning, with a few strong cells with some rotation over the coastal waters as low-level wind shear was favorable for waterspouts earlier. Only a small amount of in-cloud lightning was detected due to the relatively low cloud tops (locally over 20000 feet but mostly lower), and the trend in the intensity is decreasing at mid-morning. Only minor convective activity is expected the rest of today as the HREF ensemble showed the probability of CAPE > 500 J/kg near zero, and the thickness of the near saturation in the low layers gradually decreases though moisture will remain up to around 700-750 mb this afternoon. Thus, a few showers will continue this afternoon and possibly even early this evening with best chances near the immediate coast close to the warmer water. Some additional light snow could occur in the mountains, and our winter weather advisory continues until 7 PM in the northern mountains, though if convection remains limited there even in our daytime heating, we will consider ending the advisory earlier.

The upper low currently over southern Nevada will accelerate to the east and reach the central plains Friday while another upper low dives south a few hundred miles off the California coast and closes off. Weak ridging here between the two lows will develop and contribute to warming and clear to partly cloudy conditions, which will continue through Sunday, followed by some cooling early next week as a long-wave trough builds over the interior western US. A deeper trough digs off the west coast Tue/Wed of next week, though GFS/ECMWF ensemble solutions are rather inconsistent with placement and timing of the trough. All ensemble solutions have precipitation over many parts of California, and we will likely have precipitation down here sometime in the Wed-Thu time frame next week, possibly even later, though probabilities are higher farther north, and for many areas of central and northern California this will be the first significant rainfall of the season. NBM precipitation probabilities are mostly around 45-50 precent here Wed-Thu and will go mostly around or just above that in the weather grids. There will be cold air aloft with the trough, and current guidance shows the snow level could fall to 5000 feet or less.

AVIATION. 211700Z . SHRA and isolated TSRA to continue this morning, mainly over San Diego County, but will gradually decrease in coverage this afternoon and evening. Clouds will scatter out at times near the coast today, especially in Orange County. Cloud bases will generally be 3500 to 5000 ft MSL, with lower bases down to 2000 ft MSL in SHRA with brief vis down to 4-6 miles. Higher terrain will be locally obscured in clouds/fog and precipitation.

MARINE. Showers and isolated thunderstorms will continue over the coastal waters this morning, diminishing in coverage this afternoon and evening. No additional marine weather hazards are expected through Monday.

BEACHES. A Beach Hazard Statement remains in effect through noon today for a high rip current risk and hazardous swimming conditions.

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

SGX WATCHES/WARNINGS/ADVISORIES. CA . Winter Weather Advisory until 7 PM PST this evening for Riverside County Mountains-San Bernardino County Mountains.

Beach Hazards Statement until noon PST today for Orange County Coastal Areas-San Diego County Coastal Areas.

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.
