Synopsis
28/705 PM.

Increasing northerly flow this week is expected to cause earlier and more complete clearing of the marine layer, leading to slightly warmer temperatures and more afternoon sunshine. Breezy northerly winds will develop across southern Santa Barbara County and some interior areas each afternoon and evening.

Short Term - Tuesday through Friday
28/728 PM.

***UPDATE***

Increasing northerly flow is expected across portions of Southwest California this week, mainly tonight through Wednesday night, but potentially decreasing through Thursday. A trough passing through the Pacific Northwest will extend southward, with weak troughing into southern California tonight into Wednesday. As this occurs, northern flow will increase over SW Santa Barbara County and through the Interstate 5 Corridor, with gusty westerly winds extending into the Antelope Valley. Portions of the Central Coast will likely see gusty winds as well, during the afternoon to evening hours. Southwest Santa Barbara County is most likely to see Advisory level gusts later this evening, but especially Wednesday evening. Another area of concern is the Ventura and LA Mountains around the Grapevine, where gusts to 40 mph with isolated gusts to 50 mph are likely to occur late this evening and overnight.

With the gusty northerly flow, there is a good chance of earlier clearing for the coastal valleys, and even for some coastal areas, although this is somewhat lower confidence.

***From Previous Discussion***

Another tangential impact will likely be decreasing marine layer stratus along the Central Coast through Santa Barbara and a shallower and earlier clearing marine layer elsewhere. There will still be a weak eddy circulation over the southern coastal waters that will maintain a solid cloud cover but it will likely clear earlier in the day and not return until after midnight in most areas. Some warming is expected as well, however, a cool sea breeze is still expected each afternoon near the coast which will cap any warming there to just a couple degrees at most over the next few days. Most valleys should top out in the low to mid 80s

Long Term - Saturday through Tuesday
28/221 PM.

Troughing will return later in the week and especially over the weekend which will increase onshore flow to the east and weaken the northerly flow over the outer waters. This will lead to a deepening and longer lasting marine layer through the weekend as well as cooling temperatures.

Many ensemble solutions are indicating building high pressure early next week, but mainly north and east of southwest California. Most of the NAEFS gradients are still favoring a rather robust onshore flow pattern locally that will keep our natural air conditioning going for most areas west and south of the mountains. Could see some near 90 degrees across our warmest valley areas, but most valleys will top out in the mid 80s and coastal areas in the 60s and 70s.

Marine
28/152 PM.

Moderate confidence in forecast.

In the outer waters, winds and seas are at Small Craft Advisory (SCA) levels. Winds are expected to increase to low-end gales in the northern two zones (PZZ670/673) late this afternoon, and in the southern zone (PZZ676) this evening, with the strongest winds in western portions of these zones. Gales are expected to continue thru late Wednesday night, though they may drop below gale force at times, particularly during the morning. Overall confidence in gales is 70-80% in northern zones, and 60% in the southern zone. If wind do not reach gale force, the will be strong SCA (Small Craft Advisory) levels thru Wednesday night. SCA (Small Craft Advisory) level winds will likely continue Thu/Thu night, and while winds should drop off, seas may remain close to SCA (Small Craft Advisory) levels Fri thru Sat.

In the inner waters N of Pt. Sal, SCA (Small Craft Advisory) winds are likely (80% chc) this afternoon/eve, and again Wednesday afternoon/eve. SCA (Small Craft Advisory) level seas are likely Wednesday night thu Thu night, and there is a 40-50% chance of SCA (Small Craft Advisory) level winds Thu afternoon/eve. SCA (Small Craft Advisory) conds are not expected Fri thru Sat.

In the southern inner waters, SCA (Small Craft Advisory) winds are likely (80% chc) in western portions of the SBA Channel late this afternoon thru late tonight, and again late Wednesday afternoon thru late Wednesday night. There is 20-30% chance of gales in western portions of the SBA Channel late Wednesday afternoon/Wednesday night. Otherwise, SCA (Small Craft Advisory) conds are not expected.
