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

SYNOPSIS. Showers will gradually decrease later this afternoon and evening. Fair weather will return Friday, and there will be a gradual warming trend Friday through Sunday. Locally gusty northeast winds will occur Saturday and Sunday mornings below passes and canyons. 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. Gusty west winds will be likely at times next week mainly in the mountains and deserts.

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

Scattered showers were occurring this afternoon in San Diego County, with isolated showers farther north. The risk of snow had decreased this morning in the mountains, so the winter weather advisory was canceled. The instability had decreased as well by late morning, mostly ending the thunderstorm risk, though a few brief moderate to heavy showers could still occur this afternoon mainly in San Diego County.

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. Weak offshore flow will develop over the weekend, and that will result in local northeast winds on the coastal mountain slopes and below passes and canyons, with peak gusts likely around 35 MPH Saturday or Sunday morning. 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 lower.

AVIATION. 212130Z . Isolated SHRA possible through this afternoon, decreasing in coverage this evening. Clouds will scatter out at times today, especially along the coast. 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 through this afternoon. Clouds decreasing in coverage overnight, with mostly clear skies expected for Friday.

MARINE. Isolated showers possible through this afternoon. Otherwise, no marine weather hazards are expected through Monday.

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

SGX WATCHES/WARNINGS/ADVISORIES. CA . None. PZ . None.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
