SYNOPSIS 19 828 AM.

An upper level low pressure system approaching the California Coast will bring significantly cooler conditions today. Then, periods of rain and mountain snow will be likely tonight through Thursday. Drier and warmer conditions will return to the area going into the weekend.

SHORT TERM (TUE-FRI) 19 147 PM.

A pretty complicated forecast next few days for what likely will be minimal impact for most people. We are currently sandwiched between a cold upper low to our north and a cutoff subtropical low to our south. The southern low has been sending up thunderstorms into San Diego County but the air mass is too stable this far north. So for most of tonight the weather will be dry with increasing clouds. Increasing north winds are expected tonight across the western portion of the area, strongest in and around the western Santa Ynez Range. Will likely be some gusts between 30 and 40 mph near Gaviota but mostly 15-25 mph elsewhere so will hold off issuing a wind advisory unless advisory level winds become more widespread.

The subtropical low will shift east Wednesday while the low to the north drops south to near Pt Conception. Typically upper lows coming at us from this direction are dry but this one will have the left over moisture from the southern low to interact with and showers are expected to develop Wednesday morning, mainly south of Pt Conception. Because of the amount of cold air aloft associated with the northern upper low thunderstorms are a possibility, mainly over the coastal waters and in LA Ventura Counties. Rain amounts will generally be light but will also be quite variable.

Most areas should end up with a quarter inch or less with hourly rates a tenth of an inch or less but if a thunderstorm develops that would raise the amounts quite a bit. The other exception is the eastern San Gabriels where upslope flow will create added lift to squeeze out more precip. The concern for impactful debris flows is very low at this time but not zero because of the possibility of thunderstorms.

Snow levels will fall rapidly Wednesday to 6000' or lower by mid morning. A winter weather advisory will be issued for the LA mtns, mainly the eastern San Gabriels where up to 6" of snow could fall at higher elevations. Most of that Wednesday and Wednesday night.

The upper low moves east Thursday but leaves behind a moist air mass below 800mb and a light southerly flow which could squeeze out a few showers, again mainly south of Pt Conception and best chances in the foothills. No thunderstorm chances as the cold air aloft will have moved east with the upper low. Light snow accumulations still possible in the mountains.

Low confidence with the Friday forecast. The last couple NAM solutions have shown another upper low approaching Pt Conception Friday morning tapping into lingering low level moisture and generating some light showers. The EC and GFS and most of their ensembles are dry in most areas favoring a farther west placement of the upper low. Have gone ahead and added some low pops for Friday but low confidence and minimal impact other than to maintain a cool damp regime.

LONG TERM (SAT-TUE) 19 212 PM.

Low confidence forecast continues into the weekend given the NAM solution for Friday and possibility of that upper low lingering into Saturday (the NAM solution stops Friday evening so will have to wait for the next couple runs to see how it handles the low).

The GFS and EC as well as their ensembles are favoring a warm up back to and even slightly above normals over the weekend, keeping that upper low well south and west and allowing for some weak ridging aloft. Given the consistency of those two models and good ensemble agreement went ahead and kept the warming trend in the forecast but with the caveat that we'll have to see what happens with the Friday upper low to have more confidence either way.

Going into early next week both the EC and GFS are advertising another inside slider, this one dry but developing a strong northerly gradient Monday evening. Gusty north winds would be strongest in the I5 corridor, Santa Clarita Valley, and SRN SB County.

Another low confidence forecast for Tuesday as the deterministic GFS solution is indicating a fairly strong system coming in.

However, none of the ensembles have that nor does the EC which keeps the system well to the north. So for now will go with some increase in clouds and cooler temps but no precip.

AVIATION 20 0136Z.

At 0049Z, there was no inversion around KLAX. A moist layer will develop overnight.

S of Point Conception... Low confidence in 00Z TAF package. Mostly VFR conditions are expected for areas N of LA County through late this evening. Then low moderate confidence in timing of VCSH SHRA development south of Point Conception. There is a slight chance of TSTMs this evening through Wednesday morning across Ventura and Los Angeles counties.

N of Point Conception... Low confidence with timing of CIGs developing and CIG category. There is a 40% chance that VCSH SHRA could begin 2 hours later than 00z TAFs indicate.

KLAX... Moderate confidence in 00Z TAF through 06z then lower confidence after that. For tonight Wednesday morning, low to moderate confidence in development of -SHRA, but low confidence in timing of -SHRA and associated MVFR CIGs. There is a 15% chance of a TSTM 10Z-18Z. There is a 10% chance for an easterly wind component through Wed evening.

KBUR... Moderate confidence in 00Z TAF through 06z.then lower confidence overnight into Wednesday with development of -SHRA, with timing and associated CIG category.

MARINE 19 108 PM.

For the Outer Waters, moderate confidence in current forecast.

Stronger winds in the outer waters have arrived, so the GALE WARNING remains in effect for this afternoon and tonight. On Wednesday, SCA level winds are expected through the day. For Thursday through Saturday, winds and seas are expected to remain below SCA levels.

For the Inner Waters north of Point Sal, moderate confidence in current forecast. SCA level winds and seas are expected this afternoon through tonight. For Wednesday through Saturday, winds are expected to remain below SCA levels with a 30% chance of SCA level seas continuing through Wednesday.

For the Inner Waters south of Point Conception, moderate confidence in current forecast. There is a 70% chance of SCA level winds this afternoon through Wednesday morning across the western half of the Southern California Bight. On Wednesday, there is a 30 percent chance for SCA level winds across western sections. For Thursday through Saturday, high confidence in winds and seas remaining below SCA levels.

There is a slight chance of thunderstorms south of Point Conception tonight through Wednesday afternoon. Thunderstorms will be capable of producing locally rough seas, brief heavy rain, gusty erratic winds and frequent lightning.

BEACHES 19 108 PM.

A cold storm system will move over the region between tonight through Thursday. As this storm moves through, it will generate high surf conditions along the coast from this evening through Thursday morning. For the Central Coast, peak surf heights between 7 and 10 feet are expected while surf height of 4-8 feet are expected south of Point Conception.

A HIGH SURF ADVISORY is in effect for the Central Coast as well as the coasts of Ventura and Los Angeles counties from this evening through Thursday morning. For west-facing beaches along southern Santa Barbara County, a BEACH HAZARDS STATEMENT is in effect from this evening through Thursday morning. Along with the high surf conditions, strong and dangerous rip currents can be expected.
