Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 200 PM PDT Mon Oct 18 2021

SYNOPSIS. 18/138 PM.

Expect a cool evening after the cold front moved through the area today. Sunny and warmer conditions are slated for Tuesday through Thursday, with the exception of a slight chance of rain in northwest San Luis Obispo County on Wednesday. A more powerful rain system is expected to arrive over the weekend.

SHORT TERM (TDY-THU). 18/138 PM.

Synoptically, there is a 548 dam upper low around the CA-NV border that dragged a cold front across our area today. A minor ridge will build in from the south as this system continues its move eastward. A weak trough will just clip the northern part of our area on Wednesday, bringing a slight chance of showers to northwest SLO County. The ridge builds higher on Thursday and should bring the high temperatures of the week, to near normal levels. Ensembles have another trough extending from a closed Gulf of Alaska low impacting the area beginning next Friday or Saturday evening.

Rainfall totals, on today's system were mostly in the hundredths, but as you moved into the foothills or coastal slopes there were several locations with closer to a tenth of an inch. Skies are clear behind the front. Today will be the coldest day of the next 7 with afternoon high temps largely in the mid sixties. Not expecting low clouds and fog tonight because of the recent cold front.

Tuesday morning may have a little frost in interior locations and the Antelope Valley. It will be a sunny day as a weak ridge will move in and heights build to 576 dam. Max temps will respond to the higher heights and ample sunshine by rising 3 to 6 degrees across the coasts and valleys and 8 to 12 degrees across the mountains and interior. A weak offshore gradient may bump temps even a little higher.

A trough will sweep through the northern half of the state on Tuesday night and into Wednesday, bringing only bring a slight chance of rain to SLO county. The lift ahead of the trough should bring marine layer stratus back to the most of the coastal areas by Wednesday morning. Partly to mostly cloudy skies will follow the morning low clouds as the trough ushers in a slug of mid level moisture. Clouds should counteract and height gain warming and max temps will be similar to Tuesday's readings.

On Thursday the state will still be under the western portion of a growing. Heights will be near 585 dam. There will be near neutral flow in the E/W direction and weak offshore flow from the north. It will likely be a mostly cloudy day (perhaps partly cloudy over LA county) as a grip of mid and high level clouds ride up the backside of the ridge. The height rises and lack of onshore flow will more than compensate for the reduced sunshine and max temps will rise 3 to 6 degrees across the area making this the warmest day of the next 7 for most of the forecast area. This warming will bring most max temps to within a degree or two of normal.

LONG TERM (FRI-MON). 18/159 PM.

Both the GEFS and EC ensemble show a series of troughs pushing through the state Friday through next Monday possibly bringing a multi day rain event. There is not much consensus on exactly when the axes/fronts move through. Thus the exact timing of rain is still a bit of a question mark. The current model runs keep the bulk of the dynamics and mositure to north of the area on Friday and Saturday. The systems on Sun and Mon seem a little stronger and further south and right now this seems the best 48 hour window for rain.

GEFS seems a bit faster with the IVT plume forecast from CW3E for around the middle latitude our area being above 250 kg/ms most of the time from the 23rd to the 27th and peaking on Sunday the 24th, while the ECMWF EPS has a higher but more distinct peak on Monday. This is way out in our forecast range, but preliminary analysis shows 1-2" of rain in the Central Coast watershed is a possibility.

Other than the rain chance it looks like it will be a mostly cloudy period with max temps several degrees below normal.

AVIATION. 18/1811Z.

At 1659Z at KLAX, there was a moist layer of 8000 feet deep. The top of the inversion was around 10000 feet at a temperature of 5 C.

Moderate confidence in all TAFs. Cigs may bounce around between 015 and 035. Good confidence in a gradual switch to VFR conds between 20-22z.

KLAX . Moderate confidence in TAF. Cigs may bounce around between 015 and 035. Good confidence in a switch to VFR conds 18-20Z. Good confidence there will not be an east wind component greater than 5 kt.

KBUR . Moderate confidence in TAF. Cigs may bounce around between 015 and 035. Good confidence in a switch to VFR conds 18-21z.

MARINE. 18/124 PM.

Small Craft Advisory (SCA) level winds continue across the waters from the Central Coast to San Nicolas Island. Moderate to high confidence in SCA level winds expanding into the western portion of the Santa Barbara Channel by late this afternoon, and an SCA remains in effect for this portion starting at 3pm. SCA level winds will likely last through late tonight, then quickly diminish. Winds and seas are then expected to be below SCA levels for all coastal waters Tuesday through Thursday. A large NW swell is expected to enter the waters on Friday with moderate confidence in hazardous seas greater than 10 feet across the outer waters through the weekend.

LOX WATCHES/WARNINGS/ADVISORIES. CA . NONE. PZ . Small Craft Advisory in effect until 3 AM PDT Tuesday for zones 645-650-670-673-676. (See LAXMWWLOX).

.HAZARD POTENTIAL OUTLOOK (THU-MON).

A storm system will affect the region this weekend, with over an inch of rain in the forecast for the northern areas.
