Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 938 PM PST Mon Jan 25 2021
SYNOPSIS. 25/910 PM.
A cold storm system will continue to exit the region tonight. Drier conditions are forecast for Tuesday, then a much wetter storm system will stall over the region Wednesday and Thursday, mainly Santa Barbara and northward, then move through area later Thursday and Friday. Several inches of rain are likely with feet of high elevation mountain snow, along with moderate to strong southwest winds. Much quieter weather expected over the weekend into early Monday.
SHORT TERM (MON-THU). 25/936 PM.
A cold upper-level trough of low pressure continues to move east of the area, now located over the Lower Colorado River Basin. Showers continue across the region, mainly along the Central Coast, across the Channel Islands, and along the northern slopes of the mountains this evening.Skies will continue to clear across the Southland tonight and into the Tuesday morning. Winds are showing some signs of weakening tonight in relation to earlier in the evening. This trend should continue through tonight and into Tuesday morning. The winter weather and wind headlines look agreeable and no changes are planned to the timing at this time.
A tricky overnight low temperature forecast is in play for tonight and into Tuesday morning. If winds die off much quicker than expected, temperatures could drop colder than forecast and frost and freeze issues could pop-up. With the current thinking that winds will stay up for a majority of tonight, the current temperatures look mostly agreeable. As less winds are expected across the Los Angeles County valleys, a Frost Advisory will be added for late tonight and early Tuesday morning in the latest update.
Some warming will take place on Tuesday as weak high pressure builds in. A drier day in on tap for Tuesday, except for lingering showers along the northern slopes of the mountains in the morning and some afternoon and evening clouds over the mountains due to residual moisture.
***From Previous Discussion***
A low pressure system, currently spinning over the Gulf of Alaska, is on target to drop south and stall off the Oregon Coast by Wednesday. This will create a steady and nearly persistent stream of moist southwest flow (known in some circles as an Atmospheric River) over the region Tuesday Night through at least Thursday. Fairly certainly this will bring 2 to 3 days of nearly steady rain to San Luis Obispo County, and likely to Santa Barbara County. There is a decent chance that Ventura County will at least see several hours of rain during this period, but being right on the fringe of that flow in the latest projections, not sure if it will be a couple of hours or more like 48 hours. same story for Los Angeles County, but to a lesser degree being further away from the core of the moisture. With that said, Los Angeles and Ventura County will definitely see rain this week, but if the stalled plume stays to the north, they will have to wait until later Thursday into Friday when the plume is expected to finally move to the south. Expecting things to taper off by Friday afternoon or night.
To no surprise, San Luis Obispo and Santa Barbara Counties are in store for a copious amount of rain. Upped the amounts through Friday to 3 to 6 inches, with 8 to 10 inches possible in the foothills especially near the Santa Lucia Range. For Los Angeles and Ventura Counties, 1 to 2 inches are expected, with 2 to 5 inches in the foothills and mountains. With these types of amounts, expect peak rain rates between 0.50 and 0.75 inches per hour, which can result in debris flows near recent burn areas. A Flash Flood Watch will be considered. While the chance is not high enough yet to mention, there is a very small chance of thunderstorms on Wednesday, especially on the Central Coast. Otherwise, expect a lot of roadway and small creek flooding. Snow levels will be much higher than our current event, with most of the precipitation in the 5000 to 6000 foot range. Mountains above 6000 feet should expect several feet of snow, depending on how long they are in the moisture plume. Winter Storm Warnings will likely be issued. Period of gusty south winds are also expected, especially on Wednesday over San Luis Obispo and Santa Barbara Counties, with gusts between 40 and 60 mph expected (even near the coast). To no surprise, temperatures will stay about 10 degree below normal.
LONG TERM (FRI-MON). 25/347 PM.
For Fridays discussion, see section above. The weather for the weekend into Monday looks fairly benign, with a maybe a few residual showers linger on Saturday. Temperatures will remain below normal, but could touch normal on Monday.
AVIATION. 26/0003Z.
At 23Z at KLAX, there was no marine layer nor an inversion.
Overall, moderate confidence in TAFs with higher confidence in flight category and less confidence in wind speeds. VFR conditions are likely to continue through the period with passing scattered showers. There is a 20-30% chance of a quick shower mainly for sites north of Point Conception through the evening, before tapering off after midnight. If a shower does develop, conditions will likely briefly drop to MVFR, or IFR for a heavier shower. As for winds, gusty west to northwest winds will likely continue through early to mid- evening, then start to diminish overnight. Wind speeds may be off by up to 10 kt and timing may be off by an hour or two. Areas if moderate to possibly severe turbulence are possible through the evening.
KLAX . Moderate confidence in TAF. There is a 20% chance of showers through the evening. If a shower does develop, MVFR to possibly IFR cigs are possible. Otherwise good confidence in VFR conditions. Gusty west winds will likely continue through the evening, then start to taper off after midnight. Good confidence in no east wind component.
KBUR . Moderate confidence in TAF. There is a 20% chance of showers through the evening. If a shower does develop, MVFR to possibly IFR cigs are possible. Otherwise good confidence in VFR conditions. Gusty northwest winds will likely continue through the evening, then start to taper off after midnight, and areas of turbulence are likely.
MARINE. 25/826 PM.
***Very dangerous wind and sea conditions across the entire coastal waters through early Tuesday*** Widespread Gale force winds will continue to affect the entire coastal waters through this evening before tapering off overnight into Tuesday morning. Winds will likely gust up to 40 kt, but some local areas may gust in excess of 50 kt through the evening. The Gale Warning will expire at 9am, but there is a chance that winds may diminish faster by around dawn. There will likely be SCA level winds Tuesday morning before diminishing below SCA level by the afternoon.
In addition to gusty winds, dangerous seas will also remain an issue through Tuesday. Seas of 15 to 20 feet are likely through this evening across the waters north of Point Conception and southwest of the Channel Islands. Seas of 10 to 16 feet are likely through tonight for the waters inside the Southern California Bight. Seas will begin decreasing Tuesday before rising again Wednesday.
The decrease in winds will be short-lived on Tuesday as the next major storm system will be making its approach Tuesday night. Winds will shift to the south on Tuesday evening and strengthen to at least SCA level after midnight spreading from north to south. There will likely be another round of Gales across the waters from the Channel Islands northward, with a 50% chance for the Santa Barbara Channel starting during the early morning hours on Wednesday through much of Thursday. Models are indicating lighter winds across the waters adjacent to LA and Orange Counties due to the fact that the storm will likely stall across the Central Coast. Then by Thursday night winds will increase to SCA level. So the forecast for these waters has much lower confidence because this forecast track may change with future model runs.
BEACHES. 25/843 PM.
Surf will peak at 14 to 18 feet with local sets to 20 feet on the Central Coast through tonight. On west facing beaches south of Point Conception, surf will peak at 8 to 12 feet with local sets to 14 feet through early Tuesday. Surf will slowly subside on Tuesday before increasing again Wednesday.
There may be minor coastal flooding through Tuesday morning, especially within a few hours of the times of high tide and again Thursday. There will be strong and dangerous rip currents on all area beaches through Tuesday. The surf will likely cause some beach erosion.
LOX WATCHES/WARNINGS/ADVISORIES. CA . High Surf Advisory in effect until 10 PM PST Tuesday for zones 34-35. (See LAXCFWLOX). Wind Advisory in effect until 6 AM PST Tuesday for zones 34>36-39>41-46-59-87. (See LAXNPWLOX). Wind Advisory in effect until 10 PM PST this evening for zones 37-44-45-88-547. (See LAXNPWLOX). Winter Weather Advisory in effect until 10 PM PST this evening for zones 38-51-52. (See LAXWSWLOX). High Surf Advisory in effect until 6 PM PST Tuesday for zones 39>41-87. (See LAXCFWLOX). Frost Advisory in effect from 3 AM to 9 AM PST Tuesday for zones 44-45-88-547. (See LAXNPWLOX). Winter Storm Warning in effect until 4 AM PST Tuesday for zones 53-54. (See LAXWSWLOX). High Wind Warning in effect until 10 PM PST this evening for zones 549-550. (See LAXNPWLOX). PZ . Gale Warning in effect until 9 AM PST Tuesday for zones 645-650-655-670-673-676. (See LAXMWWLOX).
.HAZARD POTENTIAL OUTLOOK (THU-MON).
Multiple days of steady moderate to heavy rainfall and mountain snow is likely Wednesday through Friday. Rainfall intensities could result in debris flow issues for the recent burn areas. Feet of mountain snow may result in high mountain road closure. Gusty southerly winds could result in downed limbs, trees and power lines.
