SYNOPSIS

27/157 PM.

High pressure aloft with locally gusty north winds will result in very warm temperatures today, with record highs. Steady cooling will then follow Saturday through early next week as onshore flow returns. Fog is likely over coastal areas Friday through Sunday, with dense fog possible Friday and Saturday.

LONG TERM (TUE-FRI)

27/157 PM.

Monday's upper low passage will pass to the north. It will sweep in some upslope clouds against the north slopes. Onshore flow and falling hgts will allow for some morning stratus formation across the LA coast and the Central Coast. There will be enough cold air with this system to bring gusty NW winds to the coasts and the mtns. The cool air advection will also lower max temps 3 to 6 degrees for the csts/vlys but 5 to 10 degrees across the far interior.

Monday's cool air advection and developing offshore flow from the north will eliminate the low cloud threat on Tuesday and Wednesday. Mostly sunny skies, rising hgts and the offshore push will all team up and bring 2 to 3 degrees of warming Tuesday and an additional 1 to 2 degrees on Wednesday. Wednesday's max temps will mostly be in the 70s across the csts (away from the beaches) and vlys. These max temps are 3 to 6 degrees over normal.

Cooler and breezier on Thursday as another trof barrels through the northern half of the state. Advisory level winds will be possible for interior mountains.

Both AI-mdls are essentially dry through Sunday the 14th of March.

AVIATION

27/1737Z.

At 1649Z at KLAX, there was no marine layer. There was a surfaced based inversion with a top at 1100 ft with a temperature of 26 C.

High confidence in 18Z TAF Package. VFR conditions expected. The only exception is a 20% chance of VLIFR to LIFR conds at KPRB from 28/10Z - 28/16Z.

KLAX...Good confidence in VFR TAF. Any easterly winds will remain less than 7 knots.

KBUR...Good confidence in VFR TAF. No wind impacts are expected at this time.

MARINE

27/137 PM.

High confidence in seas remaining relatively small through at least Tuesday. Small Craft Advisory (SCA) winds will linger across the waters southwest of Point Sal through this evening. SCA level NE winds will affect the nearshore waters along the Central Coast from this evening through early Saturday morning. Strongest from Point Estero to Morro Bay.

SCA level NW winds will likely return to the waters in an area from near Point Conception down to San Nicolas Island and westward about 40 NM Saturday afternoon and evening. These winds could push into the Santa Barbara Channel by the evening, but SCA levels winds may remain localized. By Sunday, hazardous winds will increase in coverage and strength, with more certainty in impacts for mariners across the SB Channel.

By Monday afternoon/eve, hazardous winds will become very widespread covering the majority of our coastal waters. There is a moderate chance of GALES Tuesday afternoon/eve through Friday morning, focused across the Outer Waters. Details will be ironed out with time.
