Many thanks to a user for reporting an error on one of the Edit pages. The switch to PHP 7.2 caused many pages that previously worked to quit working. I fixed many but I still depend on users to report ones I missed. Please report errors HERE or send an email to me at L-36.com. Allen |

Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 351 AM PST Sat Dec 7 2019
SYNOPSIS. 07/306 AM.
A cloudy and showery weather pattern will continue across the region into Sunday as a moist air mass with a storm system moves over the area. Dry weather will develop for much of next week along with some warming for latter half of the week.
SHORT TERM (TDY-MON). 07/351 AM.
A showery weather pattern continues to develop across the area this morning as an upper-level trough near 40N and 130W continues to move toward the North Coast of California. A moist air mass continues to stream over the area this morning. A look into some breaks in the cirrus deck on GOES-West shows a large swath of clouds moving northeast into southern California. NAM-WRF solutions show 850 mb mixing ratios greater than 8 g/kg across the area pushing into the southern area this morning. An upslope flow with weak warm air advection will interact with the moisture and continue precipitation across the region. Orographic lift should enhance precipitation totals right along the south facing slopes of foothills and mountains. PoPs have been nudged high across the coastal and valley areas today.
Around an additional 0.33 to 0.50 inch of rainfall is forecast across the coastal and valley areas into Sunday night, with up to between an additional 0.75 inch to 1.50 inches in the foothills and mountains. Storm total precipitation should come in around 0.50-1.00 inch across the coastal and valley areas. Mountain locations could do a tad better with some local amounts between 2.00 and 2.50 inches possible. Much drier conditions are forecast for the desert with totals ranging around 0.10-0.20 inch.
Some marginal instability moving across the region late tonight and Sunday could bring isolated thunderstorms to portions of the area, mainly north and west of Ventura County, which includes the Cave burn area in Santa Barbara County. Isolated higher rainfall rates up to around 0.50 inch per hour are possible as this instability moves, but rainfall should remain less than USGS estimates for mud and debris flows.
While snow levels will largely remain above 6000 feet with this storm system, colder air aloft with the trough moves into the region Sunday night and into early Monday, which could lower the snow levels as low as 5000 to 5500 feet in some locations. With the moisture source region of this system, snow to water ratios should be a little lower and only an inch or two of snow is expected above 7000 feet.
LONG TERM (TUE-FRI). 07/340 AM.
Drier weather is the theme for next week. Ridging aloft will build in across the region between Monday and Tuesday, then a weak weather system will brush the area. A slight cool down is expected for Tuesday and Wednesday with a bit more clouds. By late next week, ridging aloft should grab ahold of the weather pattern for the latter half of next week and bring warmer temperatures.
AVIATION. 07/0635Z.
At 04Z, there was no marine inversion at KLAX.
Low-to-moderate confidence in the current forecast. Ceilings at or below 5000 feet will be prevalent through the period. IFR to MVFR conditions will occur in heavier rainfall at times.
KLAX . Ceilings at or below 5000 feet will be prevalent through the period. MVFR conditions will become likely after 08Z with a 30 percent chance of IFR conditions in heavier rainfall. There is a better chance of IFR conditions after 03Z. East winds greater than 7 knots are likely after 08Z and continuing through 20Z or 21Z.
KBUR . Ceilings at or below 5000 feet will be prevalent through the period. MVFR conditions will become likely after 08Z with a 30 percent chance of IFR conditions in heavier rainfall. There is a better chance of IFR conditions after 01Z.
MARINE. 07/258 AM.
For the Outer Waters, moderate confidence through this afternoon, than high confidence through at least Monday. A Small Craft Advisory (SCA) remains in effect for the northern zone PZZ670 through this afternoon and for PZZ673 just to the south through mid morning. There is a 30% chance that the southern zone PZZ676 will need a SCA through mid morning as well. On Tuesday and Wednesday, there is a 60% chance of SCA level winds across PZZ673 and PZZ676.
For the Inner Waters north of Point Sal, moderate to high confidence in current forecast. A SCA remains in effect. There is an 80% chance of SCA level winds and seas this morning. There is a 60% chance of SCA winds continuing into Saturday afternoon. For Sunday through Wednesday, high confidence in winds and seas remaining below SCA levels.
For the Inner Waters south of Point Conception, moderate to high confidence in current forecast. There is a 30%-40% chance of SCA level southeast winds across the northwestern half of the Santa Barbara Channel tonight through this morning. Otherwise, high confidence in winds and seas remaining below SCA levels through Tuesday. On Wednesday, there is a 50% chance of SCA level northwest winds across the western half of the Santa Barbara Channel.
BEACHES. 07/302 AM.
A relatively large, long-period, west to northwest swell will bring high surf conditions to the Central Coast as well as the Ventura county coast through Sunday morning.
For the Central Coast, surf heights will peak between 9 and 12 feet with local sets to 14 feet. For west-facing beaches of Ventura county, surf heights between 4 and 7 feet. Local sets to 9 feet can be expected through tonight. High surf will continue for these areas as HIGH SURF ADVISORIES will remain in effect through mid Sunday morning. For the west-facing beaches of southern Santa Barbara county and Los Angeles county, elevated surf conditions can be expected across exposed west facing beaches through Sunday with surf heights of 3-6 feet for Los Angeles county and 3-5 feet for southern Santa Barbara county.
For all coastal areas . there will be an increased risk for ocean drowning. Rip currents can pull swimmers and surfers out to sea. Large breaking waves can cause injury . wash people off beaches and rocks . and capsize small boats near shore.
LOX WATCHES/WARNINGS/ADVISORIES. CA . High Surf Advisory in effect until 8 AM PST Sunday for zones 34-35-40. (See LAXCFWLOX). PZ . Small Craft Advisory in effect until 3 PM PST this afternoon for zones 645-670. (See LAXMWWLOX). Small Craft Advisory in effect until 9 AM PST this morning for zone 673. (See LAXMWWLOX).

Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program. |
