Area Forecast Discussion National Weather Service San Diego CA 219 AM PDT Sun May 31 2020

SYNOPSIS. Developing low pressure offshore and building high pressure to the east will bring a warming trend and a shallower marine layer with limited night and morning low clouds through midweek. The low pressure area will move inland on Friday, accompanied by stronger onshore flow, cooling and a deeper marine layer into next weekend.

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

Areas of high clouds overnight have obscured the lower clouds, but sfc observations indicate patches have formed and expect some of this to persist through mid morning over coastal/western valley areas As of 2 AM PDT. The onshore sfc pressure gradients have relaxed quite a bit, and the strongest westerly wind gusts of 35-45 MPH were confined to the wind-prone mtn/pass areas. Some gusts over 20 MPH continued in the lower deserts, otherwise winds were mostly light at lower elevations.

Temperatures should be about average today to wind up the month of May and any marine stratus this morning should burn away leaving generally fair skies with areas of high clouds at times.

A broad trough over the EastPac this morning will consolidate into a cut-off low west of San Diego on Monday as strong ridges hold/build over the southern Rockies and along 150W. Large differences remain in the location and ultimate track of the low, but later this week all solutions have it moving rapidly NE as a colder, dynamic trough deepens along the West Coast. Due to the disparate model solutions regarding the development and track of the cut-off low, confidence remains low in our temperature forecast for SoCal much of this week. Model solutions come together better by next weekend as the stronger westerly winds aloft to the north, dip south. The ultimate movement of the upper low could also end up generating a few showers or even an isolated thunderstorm late this week, but at this time the chance appears quite small at any given point and time interval.

For now, expect gradual warming over SoCal early this week, along with periods of high clouds. The National Blend of Models was leaned on heavily for max temp forecasts this week, which suggests hot weather well inland, moderating to the Coast each day. Wednesday is forecast to be warmest with an anomaly of 6-12F. A quick cool-down ensues as the low offshore moves inland on Friday. Strong onshore flow will develop as the trough from the north joins the party, reinforcing the cooling well inland. It looks warmer again early next week as the trough lifts out.

AVIATION. 310845Z . Coast/Valleys . Low clouds are very patchy at this time, and will likely remain so through Sunday morning given abundant high cloud coverage and a much weaker temperature inversion. Thus, alternating periods of SCT-BKN skies are likely for most of the TAF sites for the next several hours. Cloud bases will range between 1600 and 2200 ft MSL with tops to around 2800 ft MSL. Any VIS restrictions will be confined to the foothills and higher coastal elevations. Most terminals will clear by around 17Z Sun, +/- 1 hour. Low clouds will return Sunday night, mostly after 06Z, but are only expected to affect coastal locations up to 10 miles inland. Yet again, coverage will likely be patchy, perhaps moreso than this morning, although CIGS should lower by a few hundred feet.

Mountains/Deserts . Abundant high clouds through Sunday evening, generally above 20,000 ft MSL, with VFR conditions prevailing. The desert slopes will remain gusty today, with winds surfacing at PSP and TRM at times as well, gusting to around 25 kts in the afternoon/evening. Some LLWS and MOD up/down drafts will still be possible over and east of the mtns.

MARINE. Occasional wind gusts nearing 20 knots are expected again Sunday and Monday evenings over portions of the outer coastal waters. Otherwise, no hazardous marine conditions are expected through Thursday.

BEACHES. A moderate period SSW swell will continue to generate locally elevated surf at south and southwest-facing beaches through Sunday afternoon, with sets to 5 ft (locally up to 6 ft). This elevated surf will be accompanied by a high risk of rip currents. A Beach Hazards Statement remains in effect for the Orange County beaches through 2 PM this afternoon.

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

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
