SYNOPSIS
09/225 PM.
Moderate to locally strong Santa Ana winds will continue across portions of Ventura County and northwestern Los Angeles County through tonight and into Sunday morning. Damaging wind gusts are expected to continue in the most wind-prone locations of the Santa Susana Mountains. Winds will diminish Sunday afternoon into early parts of the upcoming week. Dry conditions and partly to mostly clear skies are expected for the remainder of this weekend and into the upcoming week. Offshore flow will result in above- normal high temperatures each day in many areas, though a hard freeze is likely across the Antelope Valley tonight. Moderate Santa Ana winds may return for midweek.
.SHORT TERM (TDY-TUE)...09/225 PM.
Moderate to strong Santa Ana winds are well underway across Ventura and Los Angeles Counties, where widespread 45-60-mph northeast wind gusts are ongoing as of early this afternoon where wind headlines are in effect. Observations show that offshore pressure gradients remain strong, on the order of 7-7.5 mb for LAX-DAG.
Forecast models suggest that gradients could even strengthen a bit more going into this evening and tonight, as a large surface anticyclone strengthens across the Great Basin beneath ample subsidence aloft.
In the past few hours, a gradual weakening of offshore flow magnitudes has become apparent in surface observations. This has come with typical diurnal weakening of winds, especially well after offshore pressure gradients had previously undergone rapid tightening. Moreover, with upper support continuing to weaken over the region -- in conjunction with the eastward motion of a deep trough over the central CONUS -- stronger gusts will become increasingly confined to the most wind-prone areas through the remainder of this afternoon and into tonight and Sunday.
Given these factors, High Wind Warnings have been converted to Wind Advisories for most areas and extended through noon Sunday while the strong offshore pressure gradients persist. An exception is for the Santa Susana Mountains, where ensemble model guidance suggests high probabilities (at least 80 percent) for areas of 60-65 mph wind gusts to persist tonight into Sunday morning, resulting in extension of the High Wind Warning until noon Sunday. Elsewhere, Wind Advisories had earlier been extended until noon Sunday, and those remain in effect in most cases.
However, for the eastern San Fernando Valley, surface observations suggest that winds have weakened sufficiently to preclude continuation of the Wind Advisory there, similar to the earlier Wind Advisory cancellation for the San Luis Obispo County Mountains including the Santa Lucia range. In summary, for areas remaining in Wind Advisories through noon Sunday, areas of northeast wind gusts of 45-55 mph are expected, while for the Santa Susana Mountains, the High Wind Warning remains in effect through noon Sunday and areas of northeast wind gusts of 60-65 mph are expected.
For Sunday afternoon into Monday and Tuesday, offshore pressure gradients will decrease further, ending the strong-wind event.
However, generally light offshore flow will persist. Warming from the downslope flow will support above-normal high temperatures each day in many areas, especially on Sunday when a midlevel ridge moves over the area. Sunday high temperatures are forecast to reach the mid and upper 70s across many locations in lower elevations. However, temperatures will cool a few degrees into Monday and Tuesday in response to falling midlevel heights resulting from a midlevel shortwave trough dropping south- southeastward over the Intermountain West and weakening offshore gradients.
Regarding low temperatures through the period, cold overnight lows in the 20s and 30s are expected in many locations across the interior sections, owing to efficient radiational cooling amid the dry air mass. The coldest of these temperatures are expected across the Antelope Valley tonight -- when clear skies will further enhance radiational cooling, and temperatures as low as 19 to 23 degrees are expected in wind-sheltered locations warranting a Hard Freeze Warning. Thereafter, high clouds moving over the region should limit the degree of overnight cooling to some extent.
.LONG TERM (WED-SAT)...09/225 PM.
Offshore pressure gradients are expected to become reinforced for Wednesday and Thursday in response to surface ridging behind the previously mentioned upper trough. The trough is expected to close off as an upper low over Arizona on Wednesday. While differences exist among models regarding the depth and position of the upper low, there is consensus for offshore pressure gradients to support the potential for moderate Santa Ana winds to return Wednesday into Thursday -- especially with some upper support over the region along the western flank of the upper low.
Present indications are that winds could reach advisory levels over portions of the Los Angeles and Ventura County mountains (20 percent chance). The downslope flow will keep high temperatures above-normal in many areas for Wednesday and Thursday, while dry conditions continue west of the upper low. By the end of next week, multi-model consensus indicates upper ridging over the region allowing even warmer high temperatures to occur.
Looking further ahead to next weekend, there exists rather substantial model-to-model variability, and also substantial run- to-run variability of individual models. This casts significant uncertainty on sensible weather conditions starting next weekend.
However, there are at least some model solutions that indicate the onset of upper troughing over the east Pacific waters off the California coast, corresponding to unsettled weather including possible precipitation.
AVIATION
09/1823Z.
At 1736Z, there was no marine inversion or marine layer at KLAX.
Moderate to high confidence in 18Z TAF package. High confidence in CAVU conditions for all sites through the period. High confidence in northeasterly winds, mainly across Ventura and LA counties, but moderate confidence in speeds and timing of wind changes. Light to moderate turbulence and LLWS will be possible just about anywhere, particularly across the mountains and foothills through the period.
KLAX...High confidence in 18Z TAF as CAVU conditions are expected through the TAF period. There is a 50% chance of easterly winds near 6 knots 12Z-18Z Sun.
KBUR...Moderate to high confidence in 18Z TAF. High confidence in CAVU conditions through the period. There is a 30% chance of north to northeast winds surfacing through 22Z.
MARINE
09/1025 AM.
For the Outer Waters, moderate confidence in current forecast.
Across PZZ670/673, winds and seas are expected to remain below Small Craft Advisory (SCA) levels through Sunday. For PZZ676, there is a 80% chance of SCA level northeast winds today and a 30-40% chance of SCA level northeast winds continuing tonight and Sunday. For Sunday night through Tuesday, there is a 50-70% chance of SCA level northwesterly winds across all the Outer Waters. For Wednesday, high confidence in winds and seas remaining below SCA levels.
For the Inner Waters north of Point Sal, moderate to high confidence in current forecast. Today through Sunday night, high confidence in winds and seas remaining below SCA levels. For Monday, there is a 30-40% chance of SCA level northwest winds in the afternoon and evening hours. For Tuesday and Wednesday, high confidence in winds and seas remaining below SCA levels.
For the Inner Waters south of Point Conception, moderate to high confidence in current forecast. For today, high confidence in SCA level northeast winds and choppy seas with a 50-70% chance of Gale force winds from Point Mugu to Santa Monica. Therefore, a GALE WARNING remains in effect through this afternoon. For tonight and Sunday, there is a 50-70% chance of SCA level northeast winds continuing from Ventura southward with the strongest winds between Point Mugu and Santa Monica. For Sunday night through Wednesday, high confidence in winds and seas remaining below SCA levels.
