Max temps will climb another 1 to 3 degrees Wednesday and then hold steady on Thu. There will be offshore flow from the north each morning with a diurnal reversal to weak onshore later in the afternoon. There will only be weak onshore flow to the east (The EC has offshore flow but it is almost always a mb or two too low with its gradient fcsts). The upper ridge will continue to cover most of the state. Medium range deterministic models (GFS, EC) as well as ensembles (GEFS ECS GEPS) agree than next Wednesday and Thu will be unremarkable. Breezy but even lighter northerly winds are possible across other mountain locales, especially near the I-5 corridor. At this time it appears that the wind gusts will not reach advisory levels. Gusty winds will likely develop across southwest Santa Barbara County early next week as north to south develops over the area. Max temps Tuesday away from the beaches will be 4 to 8 degrees above normal with most of the vlys seeing max temps in the upper 80s to mid 90s range. Look for 3 to 6 locally 8 degrees of warming on Monday and then an additional 2 to 4 degrees on Tuesday. Marine layer stratus will start its retreat Monday and by Tuesday low clouds will be confined to the Central Coast and the LA coasts. In addition building high pressure over the Great Basin will weaken the onshore flow to the east each day and will actually produce weak offshore flow from the north each morning. Two days of warming are on tap for Monday and Tuesday as an upper high noses in from the west and hgts climb to 587 dam. Despite the warming all areas save for the Antelope Vly will be 4 to 8 degrees below normals. The interior of SLO county will warm even more as the cooling SW winds shut off. The weaker onshore flow and increasing hgts will bring 2 to 4 degrees of warming to most areas. Clearing will be fairly slow again but quicker than ydy as the onshore push will relax some. Marine layer stratus covers all of the csts/vlys and even the coastal slopes. Lift from a departing upper low and moderate onshore flow has lifted the marine layer to an anomalous (for October) 3200 ft. Weather-wise its seems that the calendars changed to June rather than October. Warming and drying trends are expected early next week as a ridge of high pressure squashes the marine layer towards the coast. National Weather Service Los Angeles/Oxnard CAĪ deep marine layer will support continued cool conditions with widespread night to morning low clouds focused west of the mountains today.
