14/128 PM.
Well above normal temperatures will continue in most areas through next week. The next chance of rain will be the week of Christmas.
(tdy-Wed), 14/204 PM.
Another day of well above normal temperatures for all areas except the coast where morning fog, cool ocean temps, and light onshore flow kept highs in the 60s.
Another warm up is on the way starting Monday as high pressure builds into to California and another weak Santa Ana wind event develops. Not expecting advisory level winds as upper support is almost nil but some gusts to around 30 mph are possible in the mountains and some of the valleys. Between the building high and downslope warming from the offshore flow temperatures will warm up quite a bit, especially at the coast. Overall, most areas will be in the 70s and 80s which is 10-15 degrees above normal. Humidities will be lowering as well with most areas between 15 and 25 percent during the afternoon.
Not a lot of change Tuesday and Wednesday, though gradients to the north will be increasing which should generate some increasing north winds through the Santa Ynez Range and possibly the I5 corridor. Temperatures will remain well above normal. May see a little bit of cooling at the immediate coast as gradients start to trend onshore.
(Thu-Sun), 14/224 PM.
Dry weather still expected through at least next weekend, however, models continue to advertise at least one storm coming through on or just before Christmas. There remains a fair amount of spread in terms of arrival time and amounts, which is to be expected for a storm that is still around 10 days out. Likely not a big snow producer locally as the system is tapping into moisture coming in from the southwest.
