Area Forecast Discussion National Weather Service San Diego CA 337 AM PDT Thu Oct 29 2020

SYNOPSIS. For the next week, lower level flow will generally be weak onshore near the coast and weak offshore inland. A weak coastal eddy may bring slight cooling near the coast on Friday and Saturday with some patchy night and morning low clouds and fog near the coast possible. Inland areas will warm through Sunday and Monday to 5 to 10 degrees above average. There will be locally gusty east to northeast winds near the coastal slopes of the mountains each morning with the winds possibly a little stronger and with more coverage for Sunday and Monday mornings, but with gusts mostly 35 mph or less. Weak onshore flow may begin to spread slow cooling inland for the middle of next week.

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

For the next week, lower level flow will generally be weak onshore near the coast and weak offshore flow inland. Higher resolution models show a weak coastal eddy for tonight into Friday morning and Friday night into Saturday morning. This could bring slight cooling near the coast on Friday and Saturday and some patchy night and morning low clouds and fog near the coast. This would be followed by slow warming for Sunday and Monday.

Inland areas will have a slow warming trend for today through Sunday and Monday with high temperatures on Sunday and Monday generally 5 to 10 degrees above average, except 10 to 15 degrees above average in some valley and inland coastal locations.

Offshore flow for Sunday and Monday may be slightly stronger, but with the stronger gusts near the coastal slopes of the mountains for Sunday and Monday mornings mostly 35 mph or less. Offshore flow for Tuesday and Wednesday would be weaker with some cooling spreading into the coast and valleys.

AVIATION. 290915Z . Mostly clear skies with unrestricted vis today and tonight. Local east to northeast winds gusting to 20-30 mph are expected across mountain ridges, foothills and into parts of far inland valleys today.

MARINE. No widespread hazardous marine conditions are expected through Monday. Except, patchy fog with visibility below 1 NM is possible tonight through Saturday morning.

FIRE WEATHER. Onshore flow near the coast and weaker offshore flow inland will allow for a slight recovery in humidity through Friday. Lowest daytime humidity of 10 to 15 percent for inland areas combined with locally gust east to northeast winds less than 25 mph near the coastal slopes of the mountains will continue elevated fire weather conditionS for inland areas during the day for each day through Saturday.

Offshore flow for inland areas may be slightly stronger for Sunday and Monday with greater coverage of gusty winds near the coastal slopes of the mountains for Sunday and Monday mornings, but with the stronger gusts mostly 35 mph or less. Lowest daytime humidity for inland areas will also be a little lower, around 8 to 12 percent. Elevated fire weather conditions will continue for inland areas each day, but could be briefly near critical near the coastal slopes of the mountains.

For Tuesday and Wednesday, offshore flow will weaken with slow cooling and a slow recovery in humidity spreading inland from the coast. Stronger onshore low with greater cooling and greater recovery in humidity may occur late next week as a large trough of low pressure may develop near the West Coast.

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.
