Area Forecast Discussion National Weather Service San Diego CA 146 PM PST Tue Jan 26 2021

SYNOPSIS. Dry weather will take place through tonight with chilly conditions. A low pressure system will slowly make its way down the West Coast Wednesday and Thursday, which may ebb an flow toward SoCal and may bring light precipitation to areas bordering Los Angeles County to the east. The system also features an atmospheric river that will begin to move eastward on Thursday with precipitation becoming widespread across southwestern California during the late afternoon and evening. The precipitation may become heavy at times for Thursday night into Friday morning, becoming more scattered in nature by late Friday afternoon into the evening. Drier weather will be in store with a warming trend for the weekend into early next week with high temperatures nudging closer to average.

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

SHORT TERM (Today through Thursday). Onshore flow prevails across the region with some patchy clouds across the mountains into San Diego County. Another chilly night is in store, mostly across the high desert with temperatures near the freezing mark. Temperatures will warm slightly into Thursday, though still below seasonal averages. A broad through will slowly elongate and move into the State by Wednesday and Thursday. As the system does a bit of a dance from side to side, Southwestern California will be on the eastern fringe of this moisture for Wednesday and Thursday. This will bring a chance for showers for areas near the LA County line. Models trends show the system make a decision to push off to the east on Thursday.

LONG TERM (Thursday night through Monday). As the atmospheric river pushes east, it may weaken some as it gets into our area, but it will still bring bouts of heavy rain and high elevation snowfall. Hi-res guidance bring the main band of precipitation from west to east, starting in our northern regions sometime around midnight on Thursday into early Friday morning, for southern and eastern areas. There will also be a slight chance of thunderstorms for the much of Friday as well for the mountains westward to the coast. Areas of lighter showers will continue into Friday afternoon and evening, ending from north to south Friday night.

As far as precipitation amounts go, a combination of WPC and hi-res model ensemble guidance was used to produce rain totals of an inch to locally two inches for areas west of the mountains, where highest totals will be in coastal slope communities. Snow levels will start out higher 5000 to 5500 feet on Thursday afternoon, lowering to around 4500 to 5000 feet Friday afternoon and 3500 to 4000 feet for Friday night. A Winter Storm Watch is now in effect for the San Bernardino and Riverside County Mountains for Thursday into Friday for areas above 5000 feet. Heavy snowfall is possible feet with greatest amounts across the San Bernardino County Mountains, with 8 to 16 inches possible for most, while those in the Riverside County mountains will see closer to 4 to 8 inches of snowfall is possible. The San Diego County mountains will also see a few inches of snow as well.

With rising snow levels, snow melt will add the runoff from rainfall, especially for the San Bernardino County mountains. Runoff potential will be greater due to deep layer moisture, recently saturated ground, melting snow, and higher snow levels.

Dry weather with a warming trend will follow into early next week with high temperatures on Sunday and Monday still a few degrees below average. Ensemble models develop a broader troughing pattern off into the eastern Pacific for early next week. The question of how strong this trough deepens is whether we can leave the storm door open or have to say it's closing time.

AVIATION. 262130Z . Mostly clear skies, except for local BKN clouds around 5000 feet MSL, will prevail through this evening. Clouds will increase tonight, with bases mostly above 5000 feet MSL and possible local mountain obscurations late tonight and early Wed. There is a slight chance of -SHRA/-SHSN in San Bernardino County Wed morning. Otherwise, visibility will be mostly unrestricted through Wed.

MARINE. Winds have decreased over the coastal waters with gusts in the 20-25 knot range. Seas are still 11 feet at San Clemente Basin Buoy, but this should decrease later this afternoon. The Gale Warning was downgrading to a Small Craft Advisory which will be in effect until 4 PM today. The next storm will move through Thursday night and Friday and could bring a period of gusty south winds with the onset of the storm.

BEACHES. Very large, short-period swells will gradually subside this afternoon, and the High Surf Advisory should be able to expire at 6 PM today. Elevated surf is likely with the next storm system late Thursday through Friday, with a 13-14 second swell from 270-280 degrees. The high risk of rip currents will continue through at least Friday.

HYDROLOGY. A low pressure system stalled off the California coast will begin to move eastward on Thursday with precipitation spreading across southwestern California during the late afternoon and evening. The precipitation may become heavy at times for late Thursday night into Friday morning, becoming showery Friday afternoon with the showers ending from the northwest Friday night and early Saturday.

Near the coast, rainfall could range from around 1.5 inch over northern Orange County to one inch over southern San Diego County. For the mountains, rainfall (and liquid equivalent above the snow level) will range from 2 to 3 inches for the coastal slopes of the San Bernardino County mountains to 1 to 2 inches for the coastal slopes of the mountains in Riverside and San Diego Counties.

Snow levels will start out higher 5000 to 5500 feet on Thursday afternoon, lowering to around 4500 to 5000 feet Friday afternoon and 3500 to 4000 feet for Friday night. With rising snow levels, snow melt will add the runoff from rainfall, especially for the San Bernardino County mountains. Runoff potential will be greater due to deep layer moisture, recently saturated ground, melting snow, and higher snow levels.

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