(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus66 klox 261719 afdlox area forecast discussion national weather service los angeles oxnard ca 1019 am pdt Sun may 26 2019 Synopsis 26 738 am. There will be scattered showers today across the region with isolated afternoon and evening thunderstorms and a chance of mountain snow. Conditions will be generally warmer and drier this week though with patchy overnight and morning coastal fog most days and a slight chance of mountain showers midweek. Short term (tdy-tue) 26 831 am. ***update*** there have been several reports of light rain or drizzle occurring across the forecast area this morning except for the antelope valley. Forecast looks on track for increasing showers this afternoon and evening as the upper low moves overhead across interior portions of the forecast area. Showers will increase late this morning and afternoon as the upper low moves closer to the region this afternoon. Made minor changes to the forecast in respect to precipitation amounts by trending down amounts slightly through this morning. Forecast looks on track for increasing showers this afternoon and evening as the upper low moves overhead across interior portions of the forecast area. Slight chance for thunderstorms remains in effect across interior locations across all counties. 500 mb temps peak around -22 to -24 degrees celcius late this afternoon and evening across interior locations which should cause some marginal instability to occur. Best convective indices remain over the ventura and western portion of l.A. County mountains this afternoon and evening. One fly in the ointment will be if cloud cover remains in tact over the mountains, that thunderstorm chances could be hindered with less warming across the surface. This will likely be the case across coast and coastal valleys as cloud cover should remain intact hindering afternoon convection chances and 500 mb temps are slightly warmer towards the coast. Although there are high pops in the forecast the actual rain totals should remain light to locally moderate overall today except near thunderstorms where up to an inch of rain could fall most likely across the mountains. If thunderstorms do develop, not anticipating any flash flooding as steering winds will be relatively fast moving from W NW to E se. Gusty SW winds will develop across the antelope valley and la vtu county mountains later this morning and continue through this evening. Since there is a winter weather advisory in effect for the l.A. And ventura county mountains which includes wind wording, have added a wind advisory for the antelope valley from 10 am this morning through 9 pm this evening. Expect gusty SW winds 20 to 30 mph with gusts to 45 mph. Local gust to 50 mph around lake palmdale and adjacent mountains. ***from previous discussion*** moderate onshore flow both to the east and the north along with lowering hgts have conspired to lift the marine layer to over 3000 feet. Marine layer stratus has developed and covers all of the coasts and vlys and penetrates deep into the mountain passes. A cold (for this time of year) 544 dm upper low is currently north of the bay area. A weak impulse rotating around the low is bringing a band of rain to the central coast. The low will also bring just enough lift this morning to squeeze drizzle or light rain across the coast and vlys ESP close to the foothills. The low will spin into the monterey bay area this afternoon. This will allow multiple PVA lobes to move through the forecast area. This will generate numerous showers during the afternoon. There will be enough cold air aloft this afternoon to warrant a slight chc of tstms along the kern county line. The upper low will make its closest approach early this evening as the low center moves over kings county. 500 mb temps will dip to minus 26 over northern border this will keep the threat of tstms going this evening near the kern county line. The showers and tstms will diminish later the evening and then end after midnight as the low pulls to the east and NVA washes over the area. Rainfall totals will generally be between 0.10 to 0.25 inch for the coast and vlys, except up to 0.50 inch in some foothill areas, and 0.25 to 0.75 inch in the mtns with local amounts up to 1.00 inch possible. Snow levels will fall to 6000 to 6500 feet, then drop further to 4500 to 5500 feet tonight, with accumulating snow expected over a wide area above 5000 to 5500 feet. Up to 1 inch of snow is possible form 5000 to 6000 feet, with about 2 to 4 inches between 6000 and 6500 feet, and about 3 to 6 inches with local higher amounts above 6500 feet. The highest peaks may see accumulations up to 8 or 9 inches. This snow along with gusty sub-advisory level winds will bring hazardous winter weather conditions to the mtns and a winter weather advisory is in effect through 300 am Monday. Please see the latest winter weather message (laxwswlox) for further details. Dry NW flow will bring fair skies and dry weather to southern ca Monday. |
A good eddy and onshore flow will generate a stratus deck that will cover most of the coasts and vlys Monday night and Tuesday morning. There should be some offshore trends later in the morning which will help clear the stratus out and make for a sunny afternoon. Max temps will be below normal through the period despite a warming trend. Today will be the coldest day with MAX temps 10 to 20 degrees blo normal (25 degrees blo normal for lancaster and palmdale!) there should be about 5 degrees of warming on Monday and then another 5 or so degrees on Tuesday. Long term (wed-sat) 26 346 am. The GFS and the ec agree in the synoptic pattern for extended period. On Wednesday a little trof will retrograde out from nevada. The day will start off with a good deal of morning stratus which will clear by late morning. The cold air associated with the trof will produce a slight chc of tstms over the vta mtns in the afternoon. After that dry NW flow sets up between a weak ridge to the NW and a weak trof to the se. Not much will happen during this time there will be varying degrees of morning marine layer stratus. More importantly there will be a warming trend with MAX temps rising to normal values by Thursday and then holding pretty steady through Saturday. Aviation 26 1719z. At 1700z, there was no marine inversion at klax. However, there was a moist layer up to 8000 feet. Overall, low to moderate confidence in 18z TAF package. Bkn-ovc conditions will persist through this evening. Confidence in timing of flight category changes fromVFR to MVFR is low as cigs will likely fluctuate chaotically. There will be the chance of some light showers through this evening. For tonight, moderately confident in some MVFR conditions north of point conception and vfr conditions south of point conception. Klax..Low to moderate confidence in 18z taf. Low confidence in cig forecast through this evening as there is a 50 50 chance of cigs remaining atVFR or MVFR levels with the possibilty of light showers. For tonight, moderate confidence inVFR conditions with a 20% chance of MVFR CIGS developing. Kbur... Low to moderate confidence in 18z taf. Low confidence in cig forecast through this evening as there is a 50 50 chance of cigs remaining atVFR or MVFR levels with the possibilty of light showers.

Northwest winds will increase to small craft advisory (sca) levels today and will remain at SCA levels through Thursday with the occasional slight lull during the overnight hours. For the inner waters north of point sal, moderate confidence in current forecast. There is a 70% chance of SCA level winds today through this evening. For Tuesday through through Thursday, there is a 30% chance of SCA level winds each afternoon and evening. For the inner waters south of point conception, moderate confidence in current forecast. There is a 70% chance of sca level winds this afternoon and evening and a 50% chance of sca level winds Monday afternoon and evening. For Tuesday through Thursday, winds and seas are expected to remain below SCA levels. Lox watches warnings advisories Ca... Winter weather advisory in effect until 3 am pdt Monday for zones 53-54.
