Area Forecast Discussion National Weather Service San Diego CA 145 PM PDT Thu Sep 16 2021

SYNOPSIS. Seasonally cool conditions are expected through this weekend. Winds will turn offshore Monday into Tuesday and high temperatures will slowly rise through next week. Night and morning low clouds will cover the coast and valleys through the weekend.

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

At 1 PM, skies were clear across Southern California. Temperatures were running 2 to 6 degrees below at this time yesterday, and highs are expected to range 2 to 10 degrees below normal this afternoon west of the mountains. Highs will be near seasonal averages for the deserts. High temperatures are expected to remain pretty steady through Sunday, only varying a degree or two each day. Night and morning low clouds will cover the coast and much of the valleys each night and morning through this weekend.

A weak, longwave trough is situated off the coast today. Increasing upper-level moisture will move into the region on Friday, producing some high clouds across our area, but very dry conditions near the surface will prevent any precipitation. An amplified longwave trough will progress eastward through the Pacific Northwest and Great Basin on Saturday and Sunday. The main impacts for Southern California will be some breezy winds across the mountains and the deserts slopes this weekend. Peak wind gusts are expected to reach 25-40 mph.

As the upper low moves eastward early next week, a ridge will begin to develop across the eastern Pacific. This will set the stage for winds to turn offshore late Monday into Tuesday. At this time, Santa Ana winds look to remain on the weaker side. Highs will slowly warm through the week, with temperatures expected to return to near normal or slightly above normal by Wednesday.

AVIATION. 161930Z . Coast/Valleys . Mostly clear skies expected through 03Z Friday. After 03Z cigs likely to return to coastal TAF sites, spreading into the valleys including KONT/KSBD after 08Z Friday. Vis of 3-5SM BR/HZ possible near higher coastal terrain and along the inland extent of the stratus in the valleys. Low clouds and vis restrictions expected to clear 16-18Z Fri.

Mountains/Deserts . Clear skies with unrestricted vis into Friday.

MARINE. No hazardous marine weather is expected through Wednesday.

BEACHES. Elevated surf of 3 to 5 feet, with sets to 6 feet is possible at Orange County and northern San Diego County beaches today. Surf will continue to decrease through the weekend. Strong rip and longshore currents are likely at all beaches today.

FIRE WEATHER. Fire weather conditions will continue elevated to locally critical for a few hours along the desert slopes and near passes today, where very low RH (5-10%) and gusty southwest to west winds will prevail, especially in the afternoon and evening. Slightly higher RH is on the way for Fri-Sat with a slight increase in winds by Saturday. Temperatures will remain near or below average through the weekend, followed by warming to around average early next week under high pressure aloft and weak offshore flow.

SKYWARN. Skywarn activation will not be needed today.
