Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 354 AM PST Sun Dec 10 2023
SYNOPSIS
10/253 AM.
The Santa Ana winds will continue across portions of Ventura County and northwestern Los Angeles County through this morning.
Dry conditions and partly to mostly clear skies are expected through at least the middle of the upcoming week. Offshore flow will result in above-normal high temperatures each day in many areas. The dry air, however, will allow colder than normal overnight lows in wind sheltered areas. Moderate Santa Ana winds may return for midweek.
.SHORT TERM (TDY-TUE)...10/228 AM.
An upper ridge poking in from the SW will rise hgts from 584 dam to 586 dam. More importantly the sfc gradients which are 2 mb stronger offshore from the east and 2 mb weaker from the north. By afternoon there will be onshore trends both to the north and to the east. The current suite of wind advisories that cover most of LA and VTA counties looks good through noon. The strongest winds will be focused in an line from Santa Clarita to Simi Vly this is where warning level gusts will in the hills separating Simi Vly from Fillmore. Given the stronger push from the east the winds will likely be a little more of an easterly direction as opposed to the NE. Cool air advection which was the main ingredient for ydys winds will not be present today and this will allow max temps to warm 6 to 12 degrees with the best warming across the mtns and far interior. Some beaches may cool a few degrees as the sea breeze sneaks in a few hours earlier.
Tonight there the dry air will again bring an odd mix of overnight lows with much colder lows in the wind sheltered areas and warmer than normal lows where it is windy.
Monday and Tuesday look quite benign. Offshore flow will continue from both the north and east and while they will produce some morning canyon winds but only the 15 to 25 mph sub advisory kind.
The ridge will flatten on Monday and a weak dry trof will move over the area Tuesday. A large mass of mid level clouds riding up and through the backside of the ridge will make Monday a mostly cloudy one with clearing skies arriving on Tuesday. Forecasting max temps on Monday will be tricky as the clouds and offshore flow compete against each other. Right now it looks like the Santa Ana wind corridor will warm as there will be no cool air advection.
Less offshore flow will cool the VTA and LA coasts. A little offshore push across SBA county will likely bring 2 to 4 degrees of warming to that county. Tuesday's temp forecast is much easier as the approaching trof lowers hgts and further decreases offshore flow - max temps will fall 4 to 8 degrees. Despite the cooling most max temps will end up 3 to 6 degrees above normal.
.LONG TERM (WED-SAT)...10/253 AM.
Another Santa Ana is on tap for Wednesday as Tuesday's trof morphs into an upper low near Las Vegas. This will set up NE flow aloft and some cool air advection. The forecast gradients are currently about 3 mb offshore both from the N and E. It is likely, however, that this fcst is a little on the low side as the fcst tends to become more offshore as the event grows nearer. This should be a moderate offshore event with 45 to 55 mph gusts likely in the Santa Ana prone areas.
Ridging and offshore flow are on tap for Thu and Fri. There will be sub advisory offshore canyon winds each morning. Rising hgts and continued offshore flow will bring a degree or 2 of warming each day. Overnight lows will be on the cool side in the wind sheltered areas.
There is a large amount of mdl disagreement for the weekend forecast and a large spread in the ensemble members. Most solutions agree that Saturday will be cooler and cloudier. While there is little consensus between various forecasts there does seem to be a growing possibility of rain for Sunday.
