Area Forecast Discussion National Weather Service San Diego CA 154 PM PDT Mon Jun 14 2021

SYNOPSIS. A strong area of high pressure will dominate the weather pattern this week, leading to a prolonged heat wave for much of the region. High temperatures will climb 15 to 20 degrees above average for inland areas, along with very warm overnight temperatures inland as well. A shallow marine layer will result in less warming for coastal areas, where patchy low clouds and fog can be expected nights and mornings. The large area of high pressure is expected to weaken and spread cooling inland by early next week.

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

As you can probably start to feel today, the heat is on as a strong area of high pressure centered over the Four Corners region starts to expand into Southern California. Forecast models continue to show this feature maximizing in strenght around 600 DM later in the week, quite strong, especially for this time of year. Tuesday will be the hottest day of the heat wave for many across the valleys west of the mountains. Portions of the eastern valleys of San Diego County into the Inland Empire will see highs from 100 to 110 degrees, which are prompting these areas to be under Excessive Heat Warnings through the early part of the weekend. This will not be an event where the mountains see relief from the heat, as many areas in the mountains will be in the 90s to slightly over the century mark. Forecast models continue to pick up on some high level moisture making it into the area as southwest flow aloft around the high pressure takes hold over the next few days. This may bring some areas of high level cloudiness, which may slightly inhibit high temperatures but not by much. Mountains and deserts will continue to see breezy afternoon and evening winds, leading to elevated fire weather conditions.

The coastal areas will be the only ones to escape the brutal heat as a shallow marine layer will keep temperatures moderated. Beaches can expect highs in the 70s with 80s just a couple miles further inland. This shallow layer will lead to possible low clouds and fog late nights and mornings intermittently throughout the week. Inland valleys of Orange County will still be in the 90s for much of the event, where a Heat Advisory has now been issued.

As the high pressure slightly weakens later in the week, the monsoonal flow will soon be cut off, leading to a very dry air mass. This will lead to the hottest day being in the desert by Friday. Some places across this area will reach over 120 degrees, which would be getting close to all-time high temperature records. Not only will high temperatures be hot, but also overnight low temperatures across the lower deserts will be quite warm with lows in the upper 80s to near 90 from Palm Springs to Borrego Springs. The deserts will see very hot temperatures through much of the week, but cluster analysis points to the ridge finally breaking down by early next week, which will lead to some relief from the heat across Southern California.

AVIATION. 142000Z . Coast . Areas of low clouds currently limited to the beaches. Cloud bases are about 900 ft MSL with no impacts at TAF sites. Patchy low clouds 09Z-16Z Tuesday. Cigs for any prolonged duration not likely, but intermittently possible vcnty KSAN/KCRQ. Bases would be around 400-700 feet MSL and vis around 3-6SM, locally below 1 mile.

Otherwise . SCT clouds at or abv 20000 ft MSL and unrestricted vis through tonight.

MARINE. No hazardous marine conditions are expected through Friday. However, northwest winds occasionally gusting over 20 knots are expected this evening and Tuesday evening over the outer coastal waters.

FIRE WEATHER. Very hot temperatures through much of the week and low daytime relative humidity for the deserts, mountains, mountains and also into the inland valleys early this week. High temperatures will be around 15 to 20 degrees above average for inland areas with lowest humidity in the deserts falling to around 10 percent each day. The driest day will be Tuesday, where some locales across the mountains and desrts will drop into the single digits.

The low humidity combined with gusty southwest to west winds each afternoon and evening in the mountains and deserts will bring elevated fire weather conditions each afternoon for the deserts onto the desert slopes of the mountains. This will also lead to very high mixing heights each morning and afternoon, which will increase the potential for plume-driven fire growth.

The area of high pressure will begin to break down by early next week, with cooler weather and higher humidity spreading inland.

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

SGX WATCHES/WARNINGS/ADVISORIES. CA . Excessive Heat Warning until 9 PM PDT Sunday for Coachella Valley-San Diego County Deserts.

Excessive Heat Warning from 10 AM Tuesday to 9 PM PDT Saturday for Riverside County Mountains-San Bernardino County Mountains-San Bernardino and Riverside County Valleys-The Inland Empire-San Diego County Mountains.

Excessive Heat Warning until 9 PM PDT Saturday for Apple and Lucerne Valleys-San Gorgonio Pass Near Banning.

Excessive Heat Warning from 10 AM Tuesday to 9 PM PDT Friday for San Diego County Valleys-Santa Ana Mountains and Foothills.

Heat Advisory from 10 AM Tuesday to 9 PM PDT Friday for Orange County Inland Areas.

PZ . NONE.
