Area Forecast Discussion National Weather Service San Diego CA 417 AM PDT Tue Sep 29 2020

SYNOPSIS. Areas of low clouds and locally dense fog for coastal areas will clear quickly during the morning. Hot and very dry conditions will continue through Thursday with the the heat extending almost to the coast. There will be gusty east winds for the coastal slopes of the mountains and inland valleys today. The return of onshore flow and weakening of high pressure aloft will spread cooling inland for Friday through early next week, but with high temperatures remaining above average. Areas of night and morning coastal low clouds and fog will gradually return and spread farther inland for the weekend into early next week.

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

SHORT TERM (Today through Thursday). Areas of low clouds and fog have returned overnight, spreading locally inland along the Orange County coast and spreading inland into the far western valleys in San Diego County. The marine layer is near 800 to 1000 feet deep. Fog will be locally dense early this morning for higher coastal terrain into the western valleys in San Diego County. The cansac WRF shows the low clouds clearing quickly this morning after sunrise.

Weak offshore flow will continue today. For the coastal slopes of the mountains into the adjacent inland valleys in Riverside and San Diego Counties, gusty east winds will continue this morning, gradually diminishing during the afternoon. The stronger gusts will mostly be 35 mph or less, but with isolated gusts to 45 mph in the windiest locations. There will also be gusty north winds below the Cajon Pass, mostly 30 mph or less. Winds will be weaker for Wednesday and Thursday.

Warming will continue west of the mountains today with the heat peaking on Wednesday. The beaches will not be quite as hot with high temperatures mostly in the 80s. Highs of 100 or more are possible from inland coastal areas into to the valleys. Thursday may not be quite as hot as high pressure aloft begins to weaken.

A Heat Advisory is in effect for the coast and valleys for today through Thursday. During the peak of the heat on Wednesday, high temperatures in the mountains and deserts are expected to be 10 to locally 15 degrees above average with high temperatures for the coast and valleys mostly 15 to 20 degrees above average. It has been sufficiently hot in late September in the past such that few high temperature records are expected to be tied or broken.

LONG TERM (Friday through Monday). For Friday through Monday, high pressure aloft will slowly weaken and onshore flow will return. There could also be a weak coastal eddy at times as shown by the local extended run of the WRF. Cooling will spread inland with high temperatures 10 to 15 degrees above average on Friday cooling to 5 to locally 10 degrees above average on Monday. Night and morning coastal low clouds will gradually return and spread farther inland, into the western valley be early next week.

AVIATION. 290930Z . Coast . Low clouds with bases 400-600 FT MSL with VIS 0-5 SM on coastal mesas. Low clouds to dissipate 12-14z. High confidence for no CIGS tonight into Wed morning.

Valley/Mountains/Deserts . Clear with unrestricted VIS today and tonight. East winds 15-20 kts gusting to 35 kts in the mountains and foothills. There will be pockets of LLWS and MOD up/downdrafts west of the mountains through this morning, strongest in San Diego County.

MARINE. Northwest winds with occasional gusts around 20 kts in the outer waters this afternoon and evening. Otherwise, no hazardous marine conditions are expected through Sat.

BEACHES. Building surf today and Wed will produce a high rip current risk.

FIRE WEATHER. Hot and dry conditions will continue for inland areas this week. Through Thursday, lowest daytime humidity for the mountains, deserts, and inland valleys will fall to 8 to 12 percent. That low humidity combined with gusty east winds in the mountains and inland valleys of Riverside and San Diego Counties today will result in critical fire weather conditions. Weaker winds are expected for Wednesday and Thursday.

For Friday through Monday, onshore flow will return and high pressure aloft will weaken with cooling and higher coastal humidity spreading inland.

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

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
