(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus66 klox 242140 afdlox area forecast discussion national weather service los angeles oxnard ca 240 pm pdt Sat aug 24 2019 Synopsis 24 757 am. High pressure building over the next few days will allow for the near normal temperatures today to warm on Sunday and remain warm into next week. Night to morning coastal clouds will be less prominent over the the next few days, becoming more widespread along the coast into next week. Short term (tdy-tue) 24 237 pm. The marine inversion early this afternoon was near 700 ft deep at lax. Low clouds were noted at some of the beaches along the central coast early this afternoon, otherwise sunny skies prevailed across the region which will continue thru the rest of the afternoon. Nam forecast onshore gradients of +6.4 mb lax-dag late this afternoon will promote locally gusty s-w winds across the foothills, mtns and deserts. Temps will be much warmer and are expected to top out a few degrees above normal in the warmest vlys. Expected highs range from the upper 60s to low 70s along the immediate coast, mid 70s to mid 80s over the inland coastal plain, 90s to near 100 in the vlys and lower mtns, and upper 90s to 102 in the antelope vly. Through mon, the forecast area will be under the southern portion of an elongated upper level ridge extending from off the NRN ca coast thru central and sern ca into az. H5 heights over the forecast area will be in the 593-595 dm range thru the period. There will be generally weak SE flow aloft, but any monsoonal moisture will continue to remain far to the E of the region. The upper ridging will then weaken slightly Mon night and Tue as the remnant upper level trof from tropical storm ivo moves off the ca coast. The marine inversion will likely remain surface-based at vbg and 600- 800 ft deep or so at lax tonight thru mon, then deepen slightly mon night into Tue morning. Low clouds and fog should affect the coastal plain into the southern san gabriel vly tonight, and the central coast along with the vtu l.A. County coast night and morning hours from Sun night thru Tue morning. Patchy dense fog will be possible with any low clouds tonight, and mainly along the central coast sun and Mon nights. Otherwise, mostly clear skies will prevail tonight thru tue, altho a few mid level clouds may move into the area from the S Sun and Sun night. Afternoon onshore gradients (lax-dag) are forecast by the NAM to be around +6.7 mb sun, +7.2 mb mon, and +8.1 mb tue. These gradients will continue to promote some gusty S to W winds each afternoon and early evening across the foothills, mtns and deserts. In addition, gradients from sba-smx will lower to as low as -2.0 mb Sun evening and Mon evening, with mild sundowners possible along the sba s coast and santa ynez mtns. With decent warming in the boundary layer and 950 mb level, and high 1000-500 mb thicknesses (582-586 dm), temps away from the coast are forecast to warm further Sun the Tue to about 4-10 deg above normal away from the coastal plain. Highs each day for the warmest vlys and lower mtns will be in the mid 90s to about 103. As far as tropical storm ivo... As of 2 pm pdt, the center was about 425 miles W of the southern tip of baja california. Ivo will continue to weaken as it continues to move nnw parallel to baja and be downgraded to a tropical depression by late Sun morning as it continues to move across cooler waters. The only affect for SRN ca from ivo will be surf related. See the "beach discussion" below for more details. Long term (wed-sat) 24 239 pm. The upper level ridging will build back into the area Wed and thu, with a 594 dm high at h5 expected to be over SRN ca by late fri. Upper level ridging will then persist over the region thru sat, with h5 heights lowering slightly to 592-593 dm. The marine inversion should increase slightly for Tue night and wed, with night and morning low clouds and fog expected to expand to all coastal areas and some adjacent vlys. The upper level ridging will lower the marine inversion again to below 1000 ft deep late this week resulting in reduced low cloud coverage. The central coast and mainly l.A. County coast should have the night and morning low clouds Thu night into Sat morning. Otherwise, mostly clear skies will continue across the forecast area thru the extended period. Temps will continue to be several degrees above normal away from the immediate coast Wed thru sat. Highs in the warmest vlys and lower mtns should be generally in the 90s to near 100 each day. Aviation 24 1713z. At 1700z, the marine inversion at klax was based at 1000 feet. |
The top of the inversion was 3700 feet with a temperature of 24 degrees celsius. Overall, high confidence in 18z valley desert tafs, but only low to moderate confidence in coastal tafs. Shallow marine inversion will keep any stratus fog confined to coastal sites tonight. However, confidence in coastal tafs is low as there is an equal chance of either clear conditions or ifr lifr conditions. Klax... Overall, moderate confidence in 18z taf. High confidence in vfr conditions through this evening. For tonight, moderate confidence in return of stratus fog, but low confidence in timing (could be + - 4 hours of current 10z forecast) and flight category (could be either ifr or lifr). Kbur... Overall, high confidence in 18z taf. There is a 10% chance of ifr lifr conditions 11z-15z. Marine 24 205 pm. For the outer waters, moderate to high confidence in current forecast. Today through Wednesday, high confidence in winds and seas remaining below small craft advisory (sca) levels. On Thursday, there is a 60% chance of SCA level winds developing. For the inner waters north of point sal, moderate to high confidence in current forecast. High confidence in winds and seas remaining below SCA levels through Wednesday. On Thursday, there is a 50% chance of SCA level winds during the afternoon and evening hours. For the inner waters south of point conception, moderate to high confidence in current forecast. Today through Thursday, conditions are generally expected to remain below SCA levels. The only exception will be Thursday afternoon evening when there is a 50% chance of SCA level winds across the wester half of the santa barbara channel. Patchy dense fog will impact the coastal waters the next couple of days. Visibilities of one nautical mile or less will be possible at times. A large southeast to south swell from tropical storm ivo will affect the waters Sunday through Tuesday. Swell will likely peak between 3 and 5 feet, with a slight chance of swell peaking between 5 and 7 feet. A swell from this direction would cause strong surges around and inside the vulnerable harbors, especially avalon and san pedro long beach. Large breaking waves near the coast are also likely, which has a history of capsizing small drifting boats. Beaches 24 205 pm. Tropical storm ivo, currently about 350 nautical miles wsw of cabo san lucas, will generate a southeasterly to southerly swell which will reach the coastal waters california Sunday and persist through Tuesday. The peak of the swell should occur Sunday afternoon through Monday morning with a period around 12 seconds. The peak of the swell heights will most likely fall between 3 and 5 feet, with a slight chance of swell heights reaching 5 to 7 feet. Dangerous rip currents and large breaking waves on rock jetties are certain. Surf heights should reach at least 3 to 6 feet over south facing beaches, with a chance of peak surf reaching 6 to 8 feet especially for los angeles county, which would require a high surf advisory. There is a risk of some coastal flooding as well. The highest tides will be late in the afternoon, and should reach 5.7 to 6.7 feet. If the peak swell ends up between 4 and 5 feet as expected, flooding impacts would be mostly minor and mainly in the form of beach erosion and minor overflow. If the swell heights ends up in the 5 to 7 foot range, which is much less likely, more impactful flooding would be expected for vulnerable areas like pebbly beach in avalon and unprotected parts of the long beach peninsula. Lox watches warnings advisories Ca... Beach hazards statement in effect from 2 am pdt Sunday through Tuesday morning for zones 40-41-87. (see laxcfwlox). Pz... None.
