Area Forecast Discussion National Weather Service San Diego CA 155 PM PST Tue Mar 2 2021

SYNOPSIS. Skies will be mostly clear tonight, followed by increasing clouds Wednesday morning. Rain and mountain snow are likely Wednesday afternoon, and there is a slight chance of thunderstorms west of the mountains. The precipitation will taper off in the evening and end late Wednesday night. Dry with gradual warming Thursday and Friday. A weak trough on Saturday will bring colder weather, gusty winds and a chance for light showers. Sunday and Monday with be dry, breezy and cool.

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

The airmass was very dry this morning with a PW of only 0.13" on the 12Z NKX sounding. Low level moisture has started a slow return to the coastal areas this afternoon where dewpoints at Noon were 10 to 30 degrees higher than at the same time yesterday. Even with the increase, the dewpoint was still only 42 at Imperial Beach, 32 at Oceanside, and 21 at the San Diego Airport at Noon.

Deep layer saturation will take place tomorrow morning as a Pacific trough pulls subtropical moisture into SoCal. Wednesday morning will be mostly dry, but by noon the atmosphere will be nearly saturated from the surface to 15,000 feet, and precipitation is likely in the afternoon and evening. Max temperatures Monday will likely occur in the late morning hours before the rain begins, with afternoon temperatures slowly falling. The storm track favors greatest rain totals in San Diego County and lesser amounts to the north. Rain totals of 0.25" to 0.50" are forecast in the coastal and valleys zones, with perhaps as much as 0.75" in parts of San Diego County. In the mountains the amounts will range from 0.50" to 1.00", locally higher in San Diego County. A thunderstorm is possible in the afternoon and evening when the cold core aloft results in steeper lapse rates and greater instability. CAPE values increase to 300-600 J/kg.

Evaporative cooling will play a role in snow levels with the onset of the precip. Wet bulb zero heights start out near 4,500 feet Wednesday morning, and the precip may start out as snow at that level. Wet bulb zero heights slowly rise thereafter as the airmass saturates and warms in the southerly flow ahead of the trough. A Winter Weather Advisory will be in effect from 1 PM to 10 PM Wednesday above 5,000 feet in the SBD and RIV County mountains, and above 5,500 feet in the SAN County mountains. Snow amounts will range from a Trace to 1" at 5,000 feet, 1-3" from 5,000-7,500 ft, and from 3-6" above 7,500 feet. Precipitation will end late Wednesday night.

The precipitation ends late Thursday night in the mountains followed by a transitory ridge that will bring dry, cool weather Thursday and dry, warmer weather Friday.

Over the weekend a weak low pressure trough will move inland across California. This feature is trending farther north and a little weaker, and the chances for light precipitation here in Southern California on Saturday are low. Another weak ridge will bring dry weather and seasonal temperatures Sunday.

The ensemble outlook for next week shows a progressive pattern over Pacific with two shortwaves making landfall on the West Coast. Timing and intensity differences have yet to be ironed out, but an early precipitation projection is for rain and mountain snow Tuesday and again Thursday. Temperatures next week will generally be below average.
