Synopsis
Warm high pressure will strengthen over the Southwest this week, bringing fair skies, low humidity, and locally gusty Santa Ana winds at times. Thursday will be the warmest day, then cooling and onshore flow will prevail into the weekend. The threat of a few showers marginally exceeds climatology by Sunday, but timing is uncertain.

For Extreme Southwestern California Including Orange... San Diego...Western Riverside and Southwestern San Bernardino Counties
Moderate offshore surface pressure gradients remained from the high deserts this evening, and this was supporting NE wind gusts of 30 to around 50 MPH, mainly near the passes and in the Santa Ana Mts. Count on another very chilly night in the sheltered valleys and where winds die off, but it will be warmer on Tuesday under sunny skies. No forecast updates are planned this evening.

From previous discussion... Short Term - Today Through Thursday
A departing trough will continue to push east in Arizona through tomorrow, resulting in a weakening pressure gradient here in SoCal on the back end of this system. This has brought stiff offshore flow today, with Santa Ana winds gusting 30-45+ MPH. The winds will stick around the foothills and through the Inland Empire through Tuesday morning before becoming localized thereafter. Low temperatures will continue to be on the cooler side for wind- sheltered locations the next couple of nights, becoming not as cold by the middle of the week.

High pressure off the coast will slowly gain strength through the coming days over SoCal, where mostly clear skies and warmer weather will occur by the middle of the week. Thursday will be the warmest day overall, with temperatures 5 to 10 degrees above average for most locations. Many areas west of the mountains will be into the 70s with some spots reaching into the low 80s as the weak offshore flow pattern persists.

.LONG TERM (Friday through Early Next Week)... Model ensemble cluster analysis is in fair agreement that a trough of low pressure will deepen along the West Coast on Friday, potentially forming a cut off low near our region this weekend. There is still great uncertainty on the exact track of this system, which is a key component on how/if any wet weather occurs. The confidence on timing is gaining some movement, with the thinking that showers may come in sometime Saturday afternoon/evening, so slight chances have been introduced to the forecast. Ensembles depict Sunday having the best chance for precipitation across the area, notably San Diego County. The low will depart early next week, but the unsettled pattern may continue with cooler and breezy weather along with small chances for precipitation.

Marine
Seas and winds will continue to gradually lower overnight, though local gusts over 20 knots will continue this evening along with local seas 8-9 feet, especially in the outer waters.

Beaches
A WNW swell from around 285-290 degrees at 5-7 ft and a period of 12- 13 seconds will continue through Tuesday morning, then gradually weaken through Wednesday. This will continue the elevated to locally high surf to 7-8 feet through Tuesday morning, mainly in San Diego County. The surf and strong rip currents will create dangerous swimming conditions through Tuesday.

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