SYNOPSIS

27/1206 PM.

A low pressure system will bring cool temperatures and a chance of drizzle or light showers, as well as gusty winds to the beaches, mountains, and deserts through Thursday. A warming trend will begin Friday and continue into next week.

LONG TERM (SUN-WED)

27/131 PM.

Neutral or slight offshore flow will continue at least into early next week while a ridge of high pressure starts to build along the West coast. Low 90s are likely across the warmer valleys Sunday or Monday while coastal areas more than 5-10 degrees inland (including Downtown LA) will be in the upper 70s to mid 80s, generally 4-8 degrees above normal. Any offshore flow likely won't have much impact at the coast where highs will be near normal, mostly in the mid 60s to low 70s. And roughly a 60-80 percent chance of marine layer stratus each morning within 10 miles of the coast.

Slight warming into Tuesday then leveling off the rest of the week as high pressure aloft continues.
