Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 241 PM PST Fri Jan 22 2021

SYNOPSIS. 22/133 PM.

A cool and unsettled week of weather begins today as three storm systems move through the region through next Friday. The precipitation intensity will increase and snow levels will lower with each successive storm. There will be breaks between storms on Sunday and again midday Tuesday through midday Wednesday.

SHORT TERM (TDY-MON). 22/236 PM.

Partly to mostly cloudy skies covered the forecast area early this afternoon and will persist thru sunset. A cold front associated with a fairly strong upper level trof was moving into VTU County and will pass quickly thru L.A. County through mid afternoon. Showers have moved thru SLO/SBA Counties with up to 0.25 inch in some areas. These showers will move thru VTU/L.A. Counties with rainfall about 0.10 inch or less overall. Snow levels will drop as a colder air mass moves in, and should be near 5000-5500 feet thru this afternoon with snow showers in the mtns. Any snow accumulations should be about an inch or less above about 5500 feet.

Increasing onshore flow will prevail thru this afternoon as well, with the NAM fcst LAX-DAG pressure gradient up to +4.9 mb at 00Z. There will be gusty W to NW winds for many areas this afternoon, and should reach Advisory levels in the L.A. County mtns and Antelope vly, where a Wind Advisory is in effect for gusts up to 45 mph.

The aforementioned upper level trof will move into the forecast area by late today, then push quickly E of the area by late this evening. Another sharper upper level trof will move down the nrn and central CA coast later tonight then strengthen into a cold 544 dm H5 upper level low over srn CA on Sat. This system will move gradually E of the forecast area Sat night followed by flat upper level ridging on Sun altho another upper level trof will approach the Central Coast from the NW Sun afternoon.

Additional showers will affect the forecast area tonight through early Sat evening, with snow levels lowering further to 3500-4000 feet by later tonight and continuing into Sat. There will also be some increased instability by Sat afternoon, and a slight chance of thunderstorms is expected over the L.A. County coast and adjacent coastal waters.

Additional rainfall amounts during the period are expected to be about 0.15 to 0.33 inch across the region, with local amounts of to 0.70 inch over the eastern San Gabriel mtns. Accumulating snow of up to 2-6 inches in are forecast for the mtns above about 4000 feet, with most of the accumulating snow over the eastern San Gabriel mtns. There could be a some icy conditions across the Grapevine with up to an inch accumulation there by Saturday afternoon. Snow accumulations are not expected to be high enough to justify a Winter Weather Advisory, but motorists should be careful driving through the Grapevine and I-5 Corridor.

Dry weather will prevail later Sat night thru Sun, except for a slight chance to chance of rain moving into NW SLO County for Sun afternoon as the next weather system approaches.

A much colder upper level trof will dig down into swrn CA from the N Sun night and Mon, with H5 heights plunging to 534-535 dm over the region on Mon. A cold air mass will move into the region, as 850 mb temps fall to -1 to -3 deg C by Mon afternoon, and 950 mb temps dip to as low as 4 to 6 deg C Mon morning). This system will spread rain and mountain snow across the region Sun night into Mon, with a chance of pcpn lingering into Mon evening. Snow levels are expected to be around 3500-4000 ft Sun night then drop to around 2000 to 2500 ft Mon into Mon evening. There will also be gusty NW winds at times especially in the foothills and mtns.

Rainfall with this system is expected to be about 0.25 to 0.50 inch overall across the forecast area, with local amounts up to about 0.80 inch in the mtns. Snow accumulations are expected to be around 3 to 6 inches between 3500-4500 ft, and 6 to 10 inches above about 4500 ft. With the expected snow and gusty winds, a Winter Storm Watch has been issued for the SBA/VTU/L.A. County mtns (excluding the Santa Monica Mtns) from late Sun evening to late Mon evening. Potential impacts include wintry driving conditions and poor visibilities. Travel will likely be impacted along I-5 in NW L.A. county, including over the Grapevine, as well as the higher portions of Highway 14.

Temps across the region thru Mon are forecast to be several degrees below normal, altho the coolest day will be on Mon with highs 8-16 deg below normal.

LONG TERM (TUE-FRI). 22/235 PM.

12Z EC/GFS are in generally good agreement for the extended period. A cold upper level trof lingers over swrn CA Tue with a few more showers and snow showers possible. In fact, it looks like snow levels could be down to as low as 1500 feet late Mon night into early Tue morning, with a slight chance of snow even in the hills in and around the VTU/L.A. County vlys.

This system ejects eastward later Tue. However, a much stronger upper level trof and surface frontal system along and off the nrn CA coast will move into the area quickly late Tue night and Wed. Warm-frontal pcpn will start over SLO/SBA Counties later Tue night then spread into VTU/L.A. Counties on Wed. The main cold front with this system is expected to push into SLO/SBA Counties Wed afternoon or early evening, then into VTU/L.A. Counties later Wed night into Thu. The front will move little thru the day Thu with the potential of many hours of moderate to heavy rain over the area. The heaviest rain amounts thru Thu will depend on exactly where the front stalls, and the models are not in complete agreement on this. The strong upper level trof will linger just off the coast thru Thu night with the front probably remaining over L.A. County. Finally, the upper level trof is forecast to move over the area on Fri, with the surface front moving E and pcpn diminishing.

The models have been consistent with this system, including the mean ensembles. Our confidence in increasing that the forecast area could have a high impact rain and mtn snow event Wed thru Fri. There will be above normal PWATs as well as plenty of orographically enhanced pcpn. Very early rainfall estimates for Wed thru Fri are up to 3-4 inches for the coast and vlys, and 5-10 inches in the mountains, with the highest amounts along S facing slopes. These numbers will likely change some as additional model runs come in, but it does appear a heavy rain event will affect the region and bring potential impacts such as flash flooding, mud and debris flows out of recent burn areas, and heavy snow in the mtns mainly above 5000 feet.
