Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 152 PM PDT Sat Mar 28 2020

SYNOPSIS. 28/119 PM.

There is a chance of light showers tonight through late Sunday with any snow remaining above major pass levels. Next week will be warm and dry with many locations reaching 80 degrees Tuesday and Wednesday.

SHORT TERM (TDY-TUE). 28/152 PM.

Weak upper level trough developing off the coast of California will bring increasing high clouds to the region today, while maintaining cool temperatures. Scattered light showers have developed today across Monterey county, with a slight chance of showers developing north of Morro Bay later this afternoon. The weak upper trough will push through the region tonight through Sunday. There will be 20-50 percent pops with this weak system, mainly north of Point Conception as well as interior areas of LA/Ventura/SBA counties. The best chance of precipitation for most of these areas is expected to be Sunday afternoon. Any rain that does fall with this system is expected to be light, with totals generally less than a tenth of an inch. Snow levels will likely remain above 5000 feet and there will not be any snow issues over the major mountain passes.

The upper trough passage will also usher in gusty west to northwest winds across portions of the forecast area Sunday afternoon into Sunday night. The strongest winds will be focused across southern SBA county, the I-5 corridor in the LA county mountains, and the Antelope Valley, where gusts between 30 and 45 mph will be common. Wind advisories may be needed for portions of these areas late Sunday.

Dry northwest flow aloft sets up on Monday, with building heights across the district. This in combination with weak offshore flow to the north will bring a warming trend on Monday, with warmest areas peaking into the mid 70s. Northerly offshore flow increases Monday night into Tuesday morning (with LAX-Bakersfield gradient expected to peak around -6 mb), which will bring additional warming to most areas on Tuesday. Warmest coastal/valley areas could even see temperatures topping 80 degrees by Tuesday. The north-south offshore pressure gradients combined with some upper level wind support will enhance gusty northerly winds across southern SBA county and I-5 corridor Monday night into Tuesday.

LONG TERM (WED-SAT). 28/327 AM.

Both the EC and GFS agree that there will be dry NW flow over the area Tue and Wed and then weak ridging on Thu and Fri. It will be dry all four days.

There will be offshore flow from both the east and north on Tuesday and this will be the warmest day for the coasts and vlys. The warmest days for the interior will be Thu and Fri under the ridge.

All four days will have warmer than normal max temps and 70s will be the order of the day, but cannot rule out a few 80 degree readings in the warmest locations.

AVIATION. 28/1800Z.

At 1730Z at KLAX, there was no marine inversion.

Moderate to hi confidence in the 18Z TAFs. VFR conditions are expected at all the airfields thru early this evening, then MVFR cigs should develop at many of the coastal and vly airfields, with a 50%-60% chance of development. The cigs are expected to improve back to VFR for many of the airfields by early Sun morning, except may linger til late morning at KSBP and KSMX. The timing of onset and dissipation of the MVFR cigs may be off +/- an hour or two. Otherwise VFR conditions should prevail thru late Sun morning.

KLAX . Moderate to hi confidence in the 18Z TAF. VFR conditions are expected thru this evening, then MVFR cigs should develop 07Z-17Z, with a 60% chance of development. The cigs are expected to improve back to VFR aft 17Z Sun and continue thru Sun afternoon. The timing of onset and dissipation of the MVFR cigs may be off +/- an hour or two.

KBUR . Moderate to hi confidence in the 18Z TAF. VFR conditions are expected thru this evening, then MVFR cigs should develop 07Z-12Z, with a 60% chance of development. The cigs are expected to improve back to VFR aft 12Z Sun and continue thru late Sun morning. The timing of onset and dissipation of the MVFR cigs may be off +/- an hour or two.

MARINE. 28/121 PM.

Across the outer waters, Small Craft Advisory (SCA) winds and short period seas will cont thru late tonight for the southern two zones (PZZ673/676). There is a 30-40% chance that winds will reach SCA levels across the northern zone this evening. There is a 30%-40% chance of SCA level winds Sun afternoon into Sun night, except SCA level winds are likely across the southern zone. SCA level winds are likely Mon thru Wed. SCA level seas can be expected for Thu.

Across the inner waters north of Pt. Sal, there is a 20% chance of SCA level winds this evening. SCA level winds are likely during evening hours Mon and Tue. Otherwise, winds and seas will remain generally below SCA levels Sun thru Thu.

Across the inner waters south of Pt Conception, there is a 30% chance of SCA level winds across western portions of the SBA Channel this evening. SCA level winds are likely across much of the area Sun afternoon/evening, then there is a 40% chance of SCA level winds Mon afternoon/evening for th SBA Channel. Winds and seas will then remain below SCA levels Tue through Thu.

Overall, there will be an extended period of hazardous short period seas under 9 seconds through at least Tue.

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.
