Updated national weather service los angeles oxnard ca 457 pm pdt Mon oct 23 2017 Updated aviation discussion... Synopsis Strong high pressure aloft and gusty santa ana winds will create well above normal temperatures and record breaking heat through Wednesday. Temperatures will begin cooling, but still above normal at the end of the week. Short term (tdy-thu) afternoon high temperatures in many areas coming in above 100 degrees in la and ventura co. Downtown la, lax, burbank, and camarillo all breaking records. The high pressure aloft will continue to dominate the weather through Wednesday. 500mb heights will be around 594 dm today and Tuesday and will fall to 592 dm on Wednesday as the ridge slightly weakens. The high pressure and offshore winds will keep skies clear through the period. The offshore winds will be the major story for the next two days as they are in large part driving the temperatures. Current gradients are -6.4 mb from kdag and -6.6 mb from kbfl. On Tuesday the east to west kdag gradient is forecast to peak at -8.3 mb while the north to south kbfl gradient weakens some to -4.9 mb. This will switch the winds to more of an easterly direction. Winds will peak Tuesday. There is little upper support so this will primarily be a gradient-driven event and as such should keep wind below warning levels. There will most likely be a few warning level gusts across the ridgetops. Winds will diminish on Wednesday but will remain at advisory levels until afternoon. Very high heights (15 dm higher than normal) and offshore flow will combine to bring record heat today, Tuesday (highs 95-105 common) and likely in to Wednesday. Uncomfortably warm nights (65-75, some above 80) will raise the impact of this event. This prolonged heat poses a concern for heat-related illnesses among the vulnerable population, especially for the elderly and children. Heat warnings advisories are in effect for much of the area. Please see the product laxnpwlox for a detailed description of all heat and wind warnings and advisories. Major fire concerns exist as well (see fire weather section below). Weaker offshore flow Wednesday along with lowering heights will bring cooling to most areas, most significant north of point conception and near the coast. However, temperatures will remain well above normal with widespread 80s and 90s. Both the GFS and the ec now agree that a tall and skinny 588 dm ridge will set up on Thursday. Weak morning offshore and afternoon onshore winds will allow for a good cooldown, but max temps will be 6 to 12 degrees above normal over much of the area. Long term (fri-mon) the ridge will persist into Friday only to be replaced by a smaller ridge poking in from the SW over the weekend. While it doesn't look like the marine layer will return in strength over the weekend, it does appear that the rh levels will finally rise above the 10-20 percent levels with at least some high clouds helping to cool things down. The jet drops down over our area on Monday and that may finally be enough to get our pattern back to more seasonal for late october. Aviation 23 2350z... at 2317z, there was a marine inversion at klax at around 200 ft deep. The top of the inversion was at 1000 ft with a temperature of 35 deg c.

Marine 23 200 pm. For the outer waters, high confidence in current forecast. Winds and seas are expected to remain below small craft advisory (sca) levels through Friday for pzz670 673. For pzz676, there is a 60% chance of SCA level northeast winds Tuesday and a SCA has been issued. For the inner waters, high confidence in current forecast. For the waters north of point sal, winds and seas will remain below sca levels through Friday. For the waters south of point conception, sca level winds are likely from ventura south to santa monica today through Wednesday with the strongest winds in the morning to early afternoon hours. On Tuesday morning, there is a 40% chance of gale force gusts, but the coverage of these gusts are expected to be localized. There is a chance that the northeast winds will reach avalon and two harbors on Tuesday, but since this is a hot santa ana event the likelihood of significant winds out that far is small. 30 percent chance of 10-20 kt winds in the harbors, 10 percent chance of 15-25 kt. Fire weather 23 100 pm. A moderate to locally strong santa ana wind event will bring windy, hot and very dry conditions through Wednesday to much of los angeles and ventura counties. This event is especially concerning because of the multiple day nature of it, which we have not seen yet this season and such events have a history of large fires. The winds will peak on Tuesday with 20 to 30 mph gusting to 50 mph common in the wind prone coastal and valley areas of los angeles and ventura counties, and 20 to 35 mph gusting to 60 mph common in the mountains. Minimum humidities of 6 to 12 percent will be common through Wednesday, with poor overnight recoveries. Widespread record breaking heat will exasperate the situation, with highs between 95 and 105 common and lows between 65 and 75 common. Some windy and hilly locations may only drop into the 80s at night. A red flag warning will remain in effect through Wednesday as a result. Over san luis obispo and santa barbara counties, similar heat and dry air is expected, but easterly winds peaked on Sunday and should locally gust between 20 and 30 mph in the wind prone areas. As such, elevated fire weather conditions exist there. With these prolonged weather conditions, and the very dry fuels vegetation, extreme fire behavior is likely if any fire ignition begins... Threatening life and property. The public should be very, very careful with any potential ignition sources such as welding and brush clearing equipment, as well as campfires and cigarettes.
