(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus66 klox 232037 afdlox area forecast discussion national weather service los angeles oxnard ca 137 pm pdt Fri jun 23 2017 Synopsis A slight chance of showers and thunderstorms for the coast and some valleys north of los angeles into Saturday morning. The high will bring temperatures that are well above normal inland, and normal at the coast Saturday into Monday. The skies should be fair except for an overnight marine layer through next week. A low will move in Tuesday through Thursday for a cooling trend and increasing cloudiness. Then the end of the week may be in transition as the low exits. Short term (tdy-mon) marine lyr again hugging the coast and in some cases inland by several miles. Gradients still showing decent northerly trends which bodes well for less inland push tonight and earlier and more complete clearing Saturday. This GOES along with the 2-4 degree (c) increase in 950mb temps which should translate into 4-8 degrees (f) of warming on average for the coastal valleys and less warming in other areas. Temps should not require expansion of the current heat advisory warning product, though there will be small portions of zones, particularly southeast slo county where heat risks will be higher due to the combination of hot daytime temps and minimal overnight relief. For now though will leave the heat advisory warning alone and let it rise for the same areas through Sunday. Keeping a close eye on some moisture and energy coming up from the southeast. Lightning had been detected earlier this morning but nothing since then. Still, it's a sign that there is some decent instability with this feature even though most of it and the moisture is above 600 mb. Since there is some energy with it it won't necessarily need afternoon heating to kick storms off. However it's so dry below 600 mb that the chances for anything measurable reaching the ground are really low. So for now given its history of lightning and the trajectory of the moisture have added in a slight chance of dry lightning to the forecast for our western zones (mainly extreme western ventura county and all of sb slo counties) tonight into early Saturday. Air mass stabilizes through the day Saturday so the dry lightning potential has been confined to the night and early morning hours. This feature is gone by Sunday leaving behind a warmer air mass and continued northerly flow at the surface. So temps expected to warm a couple more degrees Sunday which should be the highest of the next several days. Sundowner winds expected to start developing as early as this evening in the SRN sb area but stronger Saturday and Sunday evenings. May be borderline advisory level there. Some winds also through the i-5 corridor but below advisory levels. A slight cooling trend is expected Monday as a weak trough moves into or and NRN ca. This will knock the ridge down and cool most areas by at least a few degrees. Long term (tue-fri) both the GFS and ec in pretty good agreement through about Thursday showing a trough developing along the west coast next week. While the patterns are similar the ECMWF now has trended slightly cooler than the gfs. So while the magnitude of cooling may not be entirely certain, confidence is high that a cooling trend will begin Monday and continue through Thursday. At that point models both show the ridge returning through next weekend, though somewhat stronger warmer on the gfs. Expecting highs to return to normal levels by Tue or wed, then slightly below normal thu before warming again Friday. Marine lyr will become more expansive especially by around mid week and again clear to near the beaches. Aviation 23 1800z. At 1723z at klax, the marine layer depth was 1700 feet. The top of the inversion was around 4600 feet with a temperature near 27 degrees celsius. Low to moderate confidence in the 18z tafs. Today is roughly |
similar to yesterday as a few coastal locations are expected to struggle to clear this afternoon. The main element of doubt with the forecast is the possibility of weaker onshore flow tonight and Saturday causing a reduction in marine cloud coverage. For now, we have kept the marine clouds in the valleys, but do not be surprised if the valley tafs soon reflect a sunnier, more optimistic tone. Elsewhere the marine clouds will return tonight with another round of MVFR to ifr conditions. Klax... Moderate confidence in taf. There is a 30 percent chc of no afternoon clearing. Very high confidence that there will not be an east wind component over 5kt. Kbur... Low to moderate confidence in the 18z taf. There is a 40 percent chc that CIGS will not make it into the airfield tonight at all. Marine 23 900 am. Winds will remain below small craft advisory levels through Friday night across the outer waters, then gradually increase through Monday. There is a 50 percent chance of small craft advisory level winds developing Saturday morning with a better chance by the afternoon across the outer coastal waters. Across the inner waters, confidence is high there will not be any sca through the weekend. However there will be a 50-60% chance for local gusts to 25 kt across the W portion of the sba channel. A 2-3 foot south swell at 16-17 second period will last through Saturday and may pose a risk for breaking waves nearshore. People boating or kayaking near shore should use extra caution. Although the coverage of dense fog is easing a bit, there is still a 40% chance of patchy dense fog during the night and mornings through the weekend. Fire weather 23 900 am. Hot and dry conditions will continue through Monday of next week. The hot conditions will also bring the potential for plume dominated fires which can create their own intense winds. Gusty onshore winds will continue today focusing the concerns to interior los angeles county. Weaker but locally breezy northwest winds should follow Saturday through Monday... Shifting the area of concern to santa barbara county and the tejon pass. Tropical moisture aloft will move through the area tonight and Saturday. While this should have little impact on humidities at the surface, this moisture is producing a small area of high- based thunderstorms. If this feature persists, dry lightning will be a major concern as an ignition source with little to no rain. With such conditions, elevated fire weather concerns will persist through Monday, especially over all interior sections away from the influence of the marine layer. If fire ignition occurs, dangerous fire behavior should be expected. As such, the public should be extreme careful when handling potential ignition sources such as cigarettes, campfires, hand torches and metallic weed trimmers. Lox watches warnings advisories Ca... Heat advisory in effect until 9 pm pdt Sunday for zones 38-52>54. (see laxnpwlox). Beach hazards statement in effect through Saturday evening for zones 40-41-87. (see laxcfwlox).
