SYNOPSIS

07/824 PM.

A warming trend will continue through Sunday, then a weak storm system will move into the region and bring cooler temperatures and a chance of precipitation between Tuesday and Wednesday night. A warming trend is possible for late next week, then a cool, wet, and unsettled weather pattern looks to resume for next weekend into the third week of the month.

LONG TERM (WED-SAT)

07/250 PM.

Moist west to southwest flow with a series of storms looks to continue, potentially well into the following week, supporting the potential for a prolonged stretch of active weather. Below normal confidence on the timing and strength of this activity, although any shower activity will mostly be on the weak to moderate side through at least Friday. The initial storm continues to track towards the weaker side with most areas expecting between a tenth and a half of an inch of rain. Snow levels will likely initially be above 7000 feet, but may fall to around 6000 feet with light accumulations possible above those levels. Increased cloud cover and weak troughiness will support near to slightly below temperatures through this period. Gusty southwest to northwest winds are likely at times, but mainly below advisory levels outside of wind prone areas.

There is a 70-80 percent chance of above normal precipitation February 13-17 (next Friday through the following Tuesday). Or in other words active weather is likely to continue at times through at least the 6-10 day period. There is the potential for at least a moderate cold storm with much lower snow levels around Sunday or Monday within this window.

AVIATION

07/2352Z.

At 2350Z at KLAX, there was no marine layer.

Moderate confidence in TAFs. There is a 20-30% chance of IFR to MVFR cigs at KLGB from 10Z-17Z. Other than KPRB, TAF sites are expected to have VFR conditions through the period due to offshore flow.

KLAX...High confidence in TAF. No significant east wind component expected, but light north winds (under 8 knots) are likely from 04Z-10Z.

KBUR...High confidence in VFR TAF.

MARINE

07/301 PM.

Hazardous marine conditions are likely to continue through much of next week.

A long period west swell will continue to impact the region with seas of 8 to 12 feet across the outer waters and the nearshore waters along the Central Coast. Seas will trend downward going forward likely falling below Small Craft Advisory (SCA) level sometime late tonight, however NW winds are increasing thus current SCAs will continue through at least late Sunday, and may be extended through Monday night or longer. Local low end Gale Force winds may occur in the afternoon and evening hours this evening and Sunday evening (greatest chance) from Point Conception south to San Nicolas Island and west through the Outer Waters.

Local gusts to 25 kts are possible across portions of the San Pedro Channel, and from Ventura to Santa Monica tonight through Monday morning, with the strongest winds on Sunday morning.

BEACHES

07/243 PM.

A long period west swell will continue to bring high surf to Southwest California, focused across west facing beaches through late tonight. Elevated surf will likely continue through next week.
