Area Forecast Discussion National Weather Service San Diego CA 524 AM PST Mon Nov 30 2020

SYNOPSIS. Weak offshore flow will become weak to occasionally moderate offshore flow for Thursday through Saturday. Above average high temperatures early this week will cool to around average for Thursday into next weekend. Locally gusty east to northeast winds early this week near the coastal slopes of the mountains could be a little stronger and more widespread later in the week.

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

SHORT TERM (Today through Wednesday). High pressure aloft will prevail along the West Coast with generally weak lower level offshore flow across southern California. High temperatures around 5 degrees above average for the deserts, and 5 to 10 degrees above average for the coastal and valleys will begin to cool a few degrees on Wednesday. High clouds this morning will decrease in the afternoon with the incoming 12Z NKX sounding showing the moisture centered between 400 mb and about 250 mb.

Locally gusty east winds near and along the coastal slopes of the mountains and below passes and canyons will become a little stronger on Tuesday and Wednesday with the stronger gusts to around 40 mph. For Ontario, about half of the ECMWF ensemble members have weak offshore winds for late Tuesday into Tuesday night with about a quarter of the ensemble members continuing the winds into Wednesday morning. For Campo, the ECMWF ensemble members mostly show weak offshore winds today, then still weak but a little stronger winds for Tuesday into Wednesday with about a quarter of the ensemble members having moderate strength winds for late Tuesday night into Wednesday.

LONG TERM (Thursday through Sunday). There continues to be greater spread in the model guidance across southern California for late in the week into next weekend in what should be a blocking pattern in some form by the weekend across the mid latitudes of western North America. High temperatures will generally be within a few degrees of average.

The greatest spread in the wind gust intensity guidance is for Thursday with the range generally from little wind to moderate strength winds, both for areas favored for northeast and east flow. For Friday into Saturday, there is still a decent amount of the spread in the ensemble guidance with winds relatively weaker in areas favored for northeast winds and relatively stronger in areas favored for east winds. For areas favored for east flow on Friday, the bulk of the guidance supports moderate strength winds, but with support for both weaker and stronger winds from a smaller number of ensemble members. The range of winds for Saturday is weaker overall.

AVIATION. 301015Z . Locally gusty north to east winds of 15-25 kt will continue at times through the wind prone passes and canyons today and tonight. Otherwise, except for high clouds above 20000 feet this morning, mostly clear skies with unrestricted vis will prevail through tonight.

MARINE. No hazardous marine conditions are expected through Friday.

FIRE WEATHER. Weak offshore flow will become weak to occasionally moderate strength offshore flow for Thursday through Saturday. Above average high temperatures early this week will cool to around average for Thursday into next weekend. Inland areas will remain dry with lowest daytime humidity falling to around 10 percent each day.

Elevated to briefly critical fire weather conditions will continue at times into Wednesday, mainly for the coastal slopes of mountains into the inland valleys with periods of critical fire weather conditions for the mountains, valleys, and inland Orange County for Thursday through Saturday as the low humidity combines with weak to occasionally moderate strength gusty east to northeast winds.

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

SGX WATCHES/WARNINGS/ADVISORIES. CA . NONE. PZ . NONE.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
