Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 201 PM PDT Sun May 5 2024

SYNOPSIS
05/114 PM.

A cold storm system has shifted east today, leaving cooler temperatures and gusty west to northwest winds. A warming trend will begin Monday and continue through Wednesday, then little change into next weekend. Gusty northerly winds are expected at times, especially in the mountains and in southern Santa Barbara County.

.SHORT TERM (TDY-WED)...05/141 PM.

The storm has passed but it has left behind some cool and blustery winds across the area, especially near the coast as well as the mountains and Antelope Valley. Winds are expected to settle down in most areas overnight, however, gusty northerly flow will continue across the area through mid week and chances are high that wind advisories will be needed most of if not all days, at least for the late afternoon and overnight hours across in southern Santa Barbara County and possibly in the I5 corridor as well.

Temperatures will turn warmer Monday (especially inland) as heights rise and offshore flow creates some downslope warming.
This will also either eliminate or at least minimize any marine layer return. High temps should creep back into the lower 80s across the warmer valleys Monday, and likely mid 80s Tue/Wed as a high pressure ridge over the eastern Pacific nudges closer to the coastline. Not quite as warm at the coast which, despite the light offshore flow, will still get a decent sea breeze each afternoon. And with ocean temps still mostly in the high 50s, that sea breeze will cut into the temperatures quite a bit near the coast.

.LONG TERM (THU-SUN)...05/200 PM.

Still a fair amount of uncertainty for the end of the week into next weekend, though the only impacts would potentially be cooler temperatures than currently forecast and likely a faster return of the marine layer. Deterministic models are favoring a low pressure system dropping into the northern Rockies Wednesday and then retrograding back to the Great Basin Thu-Sat. However, model clusters are mixed but with more solutions favoring a continued warmer pattern with ridging along the West Coast. There should at least be a light onshore trend for the latter half of the week that should nudge temperatures slowly downward. If some of these deeper trough solutions pan out temperatures would be several degrees cooler than expected. But no rain is is expected this week or for the foreseeable future.
