Area Forecast Discussion National Weather Service San Diego CA 820 PM PDT Sun Sep 27 2020

SYNOPSIS. The marine layer and onshore flow of the past couple of days will give way to weak offshore flow through midweek as high pressure rebuilds aloft. Coastal clouds and patchy fog will prevail tonight and possibly again Monday night as it heats up inland. The dry, warm air will push slowly westward, warming coastal areas as bouts of gusty easterly winds visit the coastal slopes, passes, and foothills. Late in the week, the ridge aloft will weaken, allowing onshore flow to return and the marine layer to slowly rebuild inland next weekend.

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

At 8 PM PDT . Marine clouds were still patchy over the inner CA Bight, but were beginning to expand over northern areas. A fairly deep marine layer, and a coastal eddy maintained even cooler conditions along the coast today, while the inland valleys warmed well into the 80s and 90s. The 00Z Miramar sounding did show that slight warming above the inversion, but slight cooling was favored overall. The 7.6C marine inversion was based near 2100 FT MSL. This was up almost 300 FT from yesterday afternoon. Above the inversion, winds were mostly east up the column through 15K FT. The sfc pressure gradients were beginning to trend more offshore from the high deserts this evening, supporting E-NE winds 15 MPH with gusts to 25 MPH far inland.

A coastal eddy was propping up the marine layer today, but should collapse tomorrow, slimming the marine layer. This will keep the cooler more moist air nearer the coast tomorrow as heat builds inland in the dry air as gusty easterly breezes prevail along the coastal slopes and far inland valleys. No forecast updates are planned.

From previous discussion .

The heat will be more noticeable Monday, especially west of the mountains. An expansive area of high pressure will build in over the western states, bringing hot and dry weather to the region through much of the week. The hottest days appear to be Tuesday through Thursday. High temperatures in the Inland Empire will reach 100 to 105 degrees, and highs in the San Diego valleys will be in the mid to upper 90s, with some spots reaching or exceeding 100 degrees Tuesday through Thursday. Coastal areas will also be feeling the heat, with temperatures in the mid to upper 80s, perhaps some inland coastal areas reaching into the low 90s. A Heat Advisory was issued with the afternoon forecast package for the Inland Empire, San Diego valleys, and inland Orange County for Tuesday through Thursday.

Winds will peak in strength overnight tonight through Monday afternoon, with peak gusts to 40 mph in the mountains, passes and foothills. Higher gusts could occur in the windiest areas. Winds will decrease Monday evening, and could increase again late Monday night through Tuesday afternoon, although the strength of the winds appear to be a little weaker at this time. Lower humidity will spread further west on Tuesday towards the coast.

The Fire Weather Watch was upgraded to a Red Flag Warning this afternoon. Although the winds will be weaker Tuesday through Friday, weak offshore flow, combined with low humidity and dry fuels will elevate the fire weather threat through much of the week.

Ensembles are currently showing a slow cooling trend over the weekend as the high begins to break down. Temperatures will still be quite warm and above normal over the weekend, but lowering heights and increased onshore flow should bring temperatures back to normal by early next week.

AVIATION. 280245Z . Coast/Valleys . Low clouds with bases 1000-1500 ft MSL should become more widespread at the coast through 05Z Mon, before spreading inland through 10Z, extending approximately 30 mi from the coast. CIGS will be more uncertain at KONT, with ~30% chance of occurrence 10-15Z, though vis to 4-6 SM in HZ is possible regardless. If low clouds materialize at KONT, vis may reduce to ~2 SM. Similar vis restrictions will occur locally on elevated, obscured coastal terrain. Clouds will clear the terminals 16-18Z. Some patchy low clouds may linger Mon along immediate coast and offshore, but VFR conditions are likely to prevail at the terminals. A few low clouds could redevelop Mon evening after 03Z at the coast, but should be much less extensive, with impact to terminals being quite uncertain.

Mountains/Deserts . VFR conditions prevailing through Mon night. East SFC winds 15-20 kts, gusting up to 30 kts, can be expected near passes, and along and west of mtn ridgetops through Mon night. Localized LLWS and MOD up/downdrafts may impact these areas at times.

MARINE. Northwest winds may see gusts approach 20 kts Tuesday afternoon/evening across the outer waters. Otherwise, no hazardous marine conditions are expected through Friday.

BEACHES. Long period (17-18 seconds) SSW swell will be reinforced Tuesday. This will generate sets of 4-5 ft at SW-facing beaches, primarily in Orange County. The rip current risk will be high as a result.

FIRE WEATHER. Offshore winds surfaced in the mountains today and were continuing this evening with east to northeast winds of 10 to 20 MPH and local gusts to 25 MPH. The stronger offshore winds will occur later tonight through Monday afternoon at 15 to 25 MPH with local gusts 40 MPH. Minimum RH of 10 to 15 percent will create areas of critical fire weather conditions on Monday. A Red Flag Warning is in effect for Monday along the coastal slopes and into the eastern valleys.

Northeast to east winds will weaken late Monday, but will increase again late Monday night through Tuesday afternoon. Right now, it appears the winds will be weaker over northern areas, but just as strong, or a bit stronger over San Diego County. Weak offshore flow will continue each night and morning through the week. These winds, combined with low RH and dry fuels will continue elevated to near- critical fire weather conditions at times.

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

SGX WATCHES/WARNINGS/ADVISORIES. CA . Red Flag Warning from 5 AM to 5 PM PDT Monday for Riverside County Mountains-Including The San Jacinto Ranger District Of The San Bernardino National Forest-San Bernardino County Mountains-Including The Mountain Top And Front Country Ranger Districts Of The San Bernardino National Forest-San Bernardino and Riverside County Valleys -The Inland Empire- San Diego County Inland Valleys-San Diego County Mountains- Including The Palomar And Descanso Ranger Districts of the Cleveland National Forest-San Gorgonio Pass Near Banning.

Heat Advisory from 10 AM Tuesday to 8 PM PDT Thursday for Orange County Inland Areas-San Bernardino and Riverside County Valleys-The Inland Empire-San Diego County Valleys.

PZ . NONE.
