Fair and dry weather is expected this week. It will be a little breezier late Tuesday into Wednesday, with some coastal clouds. Stronger high pressure and weak offshore flow will bring dry and warmer weather Thursday and Friday. It looks much warmer with stronger offshore breezes this weekend.
For extreme southwestern California including Orange, San Diego, western Riverside and southwestern San Bernardino counties,
, UPDATED AVIATION DISCUSSION,
The showers ended last evening and skies have cleared out quite cleanly early this morning. With clear skies in the valleys allowing for maximum radiational cooling, there should be some patches of ground fog early this morning to go with the chilly temps, dipping into the 40s for many valleys. Skies today will be quite sunny, but with increasing high clouds late today and tonight. A trough of low pressure will move west to east to the north of SoCal Tuesday into Wednesday. This will enhance onshore breezes, especially for the mountains, deserts, and coastal waters during this time, but only to around 25-30 mph. It will also regenerate some marine layer low clouds for the coast and valleys. Later Wednesday into Friday, high pressure aloft amplifies more meaningfully, producing a noticeable warming trend for Thursday into the weekend. With colder air occupying the interior West at the same time, some offshore flow will develop for SoCal, but at this time offshore winds do not appear strong or otherwise problematic, especially through Friday. However, right now it looks like the weekend could have stronger offshore winds, but for now that is a low confidence idea. High temperatures through Wednesday will continue several degrees below average for this time of year, mostly in the 70s at lower elevations, low 80s for the low deserts. Lows will be mild, actually a few degrees above seasonal averages in the mid 40s and 50s. Highs and lows will increase by the weekend, and the offshore flow will change the distribution of the highest temperatures. That means lots of 80s west of the mountains, even close to the coast. Some upper 80s even look probable for inland coastal areas and western valleys, if all goes to plan.
011030, VFR conditions expected through the period with mostly clear skies through this morning followed by increasing clouds AOA 20kft this afternoon and evening. Weakly offshore winds will very likely keep any low clouds offshore this evening and tonight.
Weak winds expected through Tuesday morning, followed by more elevated onshore winds Tuesday afternoon and evening, with gusts in the outer coastal waters potentially exceeding 20 knots.
Southwesterly swell (3 ft at 15 seconds from 200 degrees) will bring elevated surf through today, with breaking wave heights 3 to 6 feet. Surf combined with a high tide near 6 ft will continue the potential for minor tidal overflow during today's high tide around 3:30 PM.
Tides are expected to increase for the end of the week, with tides reaching 7 ft as early as Friday, bringing the potential for at least minor tidal overflow even with little contribution from surf. Tides will peak over the weekend into early next week around 7.5 ft.
Reminder, tides mentioned have been corrected to reflect the current trends in actual tide observations.
