Area Forecast Discussion National Weather Service San Diego CA 937 PM PST Sat Jan 18 2020

SYNOPSIS. Building high pressure aloft and offshore flow will bring warmer weather through Sunday. On Monday, it will be cooler as thick high clouds from the subtropics snuff out most of the sun. There may even be some sprinkles or light rain showers as this moisture drifts overhead through Tuesday. A deep marine layer on Wednesday will continue the cooling, along with the possibility of some scattered, light rain showers. Fair, dry, and warmer weather returns later in the week. The next chance of

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

Evening Update:

Besides bumping up the sky cover a bit overnight due to the abundant high clouds streaming into the region from the Subtropical Pacific, no major changes were needed to the forecast this evening. Temperatures are trending warmer overall across the area this evening from yesterday. This is a result of weak warming aloft and abundant high cloudiness limiting radiational cooling. Relative humidity is also trending down as well. Conditions will become a bit even milder Sunday and drier as well given additional slight warming aloft. Sunday will likely be the warmest day of the next 7 days for most communities, with upper 60s near the coast, mid 70s inland and lower deserts, and 50s and 60s in the mountains and high desert.

Previous Forecast Discussion (issued at 102 PM PST):

It was a chilly start this morning as many valley temperatures fell into the upper 30s or low 40s. Abundant sunshine today remedied that quickly, so by midday many temp reports were in the upper 60s. Helping out was offshore flow, drying and warming the air further near the sfc west of the mts At Noon PST. the sfc pressure gradient had reached -8 mbS (SW NV to KSAN) and peak NE wind gusts had reached 45-50 MPH near the passes. Based on the local WRF model, these winds will continue gusty along the coastal foothills and through the passes into Sunday before weakening late in the day.

Skies will remain mostly clear overnight, and with low dewpoints, it will be quite cool again by morning, but overall, not as cold as last night. A warmer day is on tap for Sunday as high clouds begin to thicken from the west. Many areas should top 70F. Those clouds were visible today in IR imagery well off the Coast. Cloud signatures near 30N and 140W, were indicative of cyclogenesis and better organization of this feature. Several operational model runs show it peaking well offshore this weekend, then weakening as it moves over SoCal, but many maintain at least some light precip as the remnants drift over us.

Thick high clouds are likley on Monday ahead of this system and there is a chance of sprinkles or light showers for now. Tue night into Wed morning another weak disturbance from the northwest deepens the marine layer with more light showers possible, mainly along and west of the mts. None of this is expected to amount to much, but it could get things wet at times and limited sun will keep it cooler during the days.

After Wednesday, another ridge builds along the West Coast bringing SoCal fair and warmer weather to wrap up the week, but the outlook is clouded a bit into the following week. It looks like about half of the 12Z GFS ensemble members turn wet just after the weekend as a North Pacific shortwave dives down the Coast. Both the ECMWF/GFS operational runs tracks are not favorable for heavy precipitation here, but the ECMWF model, as usual, is considerably stronger with the wave and more it's ensemble members generate precip.

AVIATION.

190430Z . High clouds at/above 20,000 ft with unrestricted vis through Sunday. Locally gusty winds around 25-30 kts expected in the mountains through Sunday morning, subsiding in the afternoon.

MARINE. A fresh NW swell will generate wave heights of 6-8 feet Wednesday in the far southwestern portions of the Outer Waters, south of San Clemente Island. Otherwise, no hazardous marine conditions are expected through Thursday.

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