SYNOPSIS
28/148 PM.

A cool and unsettled weather pattern will affect southern California for the latter half of this week, as a series of weak storm systems affect the region. Isolated to scattered light showers, and areas of gusty northerly winds, are expected to accompany these systems from Wednesday through Saturday. A warming and drying trend is expected Sunday into early next week, with increasing offshore flow.

.SHORT TERM (TDY-FRI)...28/148 PM.

Satellite loops indicate a compact upper cyclone offshore near the coast of northern California. This disturbance will quickly progress south-southeastward across central and southern California late tonight into Wednesday. After another night of cold conditions including sub-freezing temperatures in portions of the interior valleys tonight, increasing cloud coverage and lowering midlevel heights will lead to Wednesday high temperatures cooling about 5-10 degrees from those of Tuesday. This system is expected to interact with enough moisture to support scattered light showers across the region. The greatest chance for showers will be over the Central Coast and adjacent inland areas, and total QPF from this first system should be one-quarter inch or less. The coverage and intensity of this activity will likely be decreasing as the system tracks farther southeast in California, and the upper low gradually weakens. In addition, the strengthening downslope component of flow aloft will contribute to minimizing precipitation chances farther to the southeast in lower elevations of LA and Ventura Counties, where some areas may not receive precipitation. While an isolated thunderstorm cannot be ruled on Wednesday in the vicinity of the Central Coast (less than 5 percent chance), modestly higher thunderstorm probabilities should remain confined to the northern coastal waters where buoyancy profiles will be more favorable for such activity.

Subsidence behind the departing disturbance will end precipitation in most areas from northwest to southeast later Wednesday into Wednesday night. Then for Thursday, persistent troughing along the Pacific Coast will maintain similarly cool temperatures, though the coverage of shower activity should be considerably less on Thursday behind the departing lead disturbance, and it should remain dry in most areas on Thursday.
Additional QPF from any precipitation on Thursday should be minimal. Snow levels will generally be around 6000 feet through the duration of precipitation through Thursday, keeping snow accumulations -- if any -- confined to the highest elevations.

Later Thursday night into Friday, another disturbance is expected to track south-southeastward over the region. Confidence is high that this pattern will allow cool temperatures to linger into Friday and Saturday. While differences among model solutions become more notable regarding the trajectory and the strength of the late-week system, there appears to be increasing model consensus for a drier outcome to occur, owing to a lower- amplitude/weaker impulse affecting the region. Downslope flow over portions of LA County and Ventura Counties in lower elevations will also limit precipitation potential. Present indications are that the highest chances for late-week precipitation will come in the form of widely scattered showers crossing the area Thursday night into Friday, with total QPF generally one-tenth inch or less. Snow levels are generally expected to lower to 4500 feet in response to additional cooling aloft with the amplifying trough, though any snow accumulations are expected to be minimal. While precipitation impacts from this system should be minimal, it is expected to be accompanied by a pronounced surge in northwesterly momentum in the lower atmosphere. This could be transferred to the surface in some areas, favoring gusty north to northwest winds in wind-prone locations including the Interstate-5 corridor on Friday. There is a 30-50-percent chance for Wind Advisories to become necessary for these winds. This second disturbance is expected to be departing the region by Friday night, followed by a drying trend.

.LONG TERM (SAT-TUE)...28/149 PM.

By late weekend and into early next week, there continues to be increasing consensus among model solutions for a midlevel ridge to build over the east Pacific waters in the wake of the departing trough. This pattern shift is expected to support pressure gradients turning increasingly offshore by Sunday into early next week. This will favor a warming trend and continued dry conditions. In addition, model ensembles suggest KLAX-KDAG offshore gradients reaching 3-6 mb by early next week, suggesting the potential for moderate to strong offshore winds in wind-prone areas.

AVIATION
28/1803Z.

At 1735Z at KLAX, there was no inversion or marine layer.

Expect some high clouds with MVFR conds across most of the region thru late tonight. Some mid level clouds associated with a frontal system may push into SLO/SBA Counties around midnight, with some MVFR cigs there late tonight, and a 20% chance of VCSH after 13Z.

KLAX...High confidence in the 18Z TAF with VFR conds thru late tonight. Some MVFR cigs are expected after 15-16z. There is a 20% chance of an east wind component of 7-8 kt thru 17Z this morning.

KBUR...High confidence in the 18Z TAF with VFR conds thru the pd.

MARINE
28/1231 PM.

In the Outer Waters, winds and seas are expected to remain below Small Craft Advisory (SCA) levels thru Thu morning. From Thu afternoon thru Sat, SCA level NW winds are expected. There is a 20-30% chance of GALE FORCE winds Thu night into Fri, mainly across the western portion of the outer waters.

For the Inner Waters N of Pt. Sal, winds and seas are expected to remain below SCA levels thru Thu morning. SCA level NW winds are likely late Thu afternoon into Thu night, and again Fri afternoon and evening. There is a 30% chance of SCA level NW winds Sat.

For the Inner Waters S of Pt. Conception, winds and seas are expected to remain below SCA levels thru early Thu afternoon. SCA level W-NW winds are likely across the SBA Channel and the inner waters from Malibu to Pt. Mugu to Anacapa Island late Thu thru Fri evening, with a bit of a lull in the winds possible Fri morning, There is a 20-30% chance of SCA conds Sat.
