Windy and Warm Thanksgiving Week
6:37 AM November 23, 2009
Windy and warm conditions will introduce Thanksgiving Week here in the Southland. High pressure is currently building into the Western States, deflecting storm systems to our north and generating offshore winds. These winds will peak tomorrow and Wednesday, before diminishing Thanksgiving.
A WIND ADVISORY for the the mountains of Los Angeles, Ventura and Santa Barbara Counties is set to expire at 10 AM this morning; however pressure gradients will continue to tighten into the afternoon hours and this will likely lead to new WIND ADVISORIES for the mountains and for some of the valleys.
Tomorrow's forecast is nothing short of spectacular as bright sunny skies and Santa Ana winds spread warmer temperatures across the coastal and valley zones. Temperatures should climb to the upper 70's for most of these areas, with a few towns topping 80. Overnight lows will continue to be chilly; especially in the wind protected valleys.
Expect this excellent weather to last through the busiest travel day of the year, Wednesday. The only potential travel impediment is the threat of strong winds; which could affect high profile vehicles traversing the passes. Hopefully we won't see winds develop this strong.
Thanksgiving could be the warmest day of the week as high pressure slowly begins to relax. It will be a clear day and winds will no longer be an issue. We'll probably have the sea breeze returning to the coastal zones during the afternoon hours.
Friday a trough of low pressure is forecast to move into the Pacific Northwest bringing cooler weather to the Los Angeles area.

Gusty Winds Sunday
3:07 PM November 21, 2009
The National Weather Service will issue a WIND ADVISORY, effective 10 PM this evening through 10 AM Monday, for the mountains of Los Angeles, Ventura and Santa Barbara Counties. North to northwest winds 20 to 35 MPH will develop in these areas with occasional gusts to 55 MPH. The strongest winds are expected late Sunday morning through evening; especially along the Interstate 5 corridor. By midday Monday winds will decrease and become offshore.

Slight Chance Of Rain Tonight
5:41 AM November 20, 2009
Later today a trough will bring cooler temps to the region, with a slight chance of showers late tonight into Saturday. Tomorrow morning, expect mostly cloudy conditions and a few lingering showers. Later in the day we'll have clearing skies and gusty winds; especially in the mountains. Sunday, into next week, high pressure will bring warm and dry conditions as offshore winds develop.
Today moisture will increase over the area and temperatures will be cooler, with clouds increasing. This afternoon we see a good chance of precipitation over the Central Coast. Rainfall will spread south and east through this evening. However, the front loses its steam by the time it reaches Southern California; so we’ll likely only have a slight chance for light showers overnight.
Rainfall amounts will be light here in Southern California. Most areas will only see a few sprinkles, totaling less than a tenth of an inch. A light dusting of snow is also possible in the mountains; however we're not forecasting any significant accumulations. Winds will become quite gusty later today and tomorrow. WIND ADVISORIES may be needed in the mountains and in the high deserts.
Thanksgiving week will be dominated by high pressure and mild temperatures. Light offshore winds will drive up temperatures Monday and Tuesday.

Windy Early, Warmer Afternoon
6:19 AM November 19, 2009
A WIND ADVISORY is in effect for the mountains of Los Angeles and Ventura Counties until 9:00 AM this morning. Gusty northerly winds in excess of 50 MPH have been noted in these areas. Expect the winds to diminish before noon.
This morning gusty offshore winds have scoured out most of the marine layer, leaving only patchy clouds and fog near the beaches; otherwise skies are crystal clear. Today, high pressure is building over California and this is producing our gusty winds and it will also cause high temperatures to bump up above normal. Look for highs to range from the upper 60's near the beaches to near 80 degrees in the valleys.
Tomorrow our brief warm up will come to an end as a cold front moves into California. We'll start out with mostly clear skies, except for patchy fog near the coast. The afternoon and evening hours will bring increasing cloudiness and cooler temperatures. Rain will spread down the Central Coast, arriving in Los Angeles after dark. Precipitation amounts are forecast to be on the light side with most of us receiving under a tenth of an inch of rain.
This is a dynamic storm system, originating in the Gulf of Alaska, thus we are expecting cool temperatures and strong winds. WIND ADVISORIES and potentially WIND WARNINGS may be issued late Friday into Saturday.
Sunday a ridge of high pressure is forecast to follow directly behind the front, orienting the winds into the Santa Ana direction. This should produce warmer temperatures for the coastal and valley zones under generally clear skies.

Cool and Breezy Day
5:46 AM November 18, 2009
This morning a cold front is passing through Southern California. Some patchy low clouds and fog is present near the beaches and it is mostly cloudy along the north facing mountains. The forecast today calls for much cooler conditions with a trough of low pressure sitting on top of California. There is a slight risk of shower activity along those north facing mountain ranges; however nothing has been reported so far this morning.
Afternoon and evening winds will be quite breezy in the mountains and in the high deserts; although no advisories are anticipated some gusts could exceed 40 MPH. Daytime highs will mostly be in the lower 70's, with 60's expected at the beaches.
Tomorrow we're forecasting brilliant weather as offshore winds and high pressure conspire to give us clear and warmer conditions. Temperatures will warm by 5 to 8 degrees for the coastal and valley zones. However overnight lows will remain very chilly. Winds will be northerly at 15 to 20 MPH Inland.
Friday a second cold front is going to move into California bringing a slight chance of showers or drizzle late in the day. The heavier rain will be limited to areas north of Pt Conception. Locally the rain will probably only amount to a few hundredths of an inch. Another round of cold temperatures and gusty winds will accompany the front. WIND ADVISORIES will be possible in the mountains and in the high deserts.
Saturday expect a cool and breezy day after the clouds clear away. Highs will mostly be in the 60's. Look for warmer temperatures Sunday.

Another Mild Day
6:44 AM November 17, 2009
Another mild day is ahead for Southern California after very chilly temperatures overnight - Camarillo tied its record low of 39 degrees. Hard freezes continued for many of the upper desert and mountain locations. One more day of high pressure and gorgeous weather is forecast with highs reaching 80 in the valleys. Not a cloud to report either as skies remain clear.
Tomorrow some pretty big changes are in store for the region as a cold front works its way south. The first thing we'll see is the marine layer ginning up some low clouds during the morning hours. After that skies will be clear to partly cloudy and the winds will kick up. Some WIND ADVISORIES may be need in the northern mountain ranges and in the high desert valleys. Daytime temperatures will run 5 to 10 degrees below today's numbers.
Thursday, winds will turn briefly offshore allowing temperatures to climb a few degrees under sunny skies.
Friday a second, more vigorous cold front is going to bring a chance of rain to Southern California. Presently rainfall amounts are not expected to be significant with most areas south of Pt. Conception receiving only a few hundredths of an inch.
Otherwise expect partly cloudy skies, gusty winds and cooler temperatures. This cooling trend will last into Saturday, with slightly warmer temperatures Sunday.

A Spectacular Autumn Day
4:56 AM November 16, 2009
A FREEZE WARNING is currently in effect for the the High Desert Valleys until 8:00 AM this morning. Dry conditions and weak offshore winds are allowing temperatures to drop well below freezing. Hard freeze conditions will persist until 8:00 AM.
A spectacular autumn day is ahead for the region with sunshine, azure skies and mild temperatures. High pressure is situated over the West and this is the reason for our beautiful weather. Weak offshore winds are blowing mainly during the morning hours; however we don't have any advisory level winds. Temperatures are going to top out in the 70's for most of us, with a few valley cities reaching 80 degrees. Despite the mild daytime temperatures, overnight lows will continue to be on the chilly side.
Little change is expected in tomorrow's forecast as high pressure remains the primary weather maker. However a series of cold fronts will begin deepening a trough into the West late Tuesday, pushing the high eastward.
Wednesday expect cooler conditions with the onshore returning and clouds increasing. A cold front will move into Southern California, but presently we're not forecasting any rainfall with this system. A second front will move into Southern California Friday bringing a slight chance of rain to the region. Temperatures will be at or slightly below normal through Friday with breezy conditions.

Cool and Windy Start to the Weekend
6:29 AM November 13, 2009
A cold front moved into the Southland overnight bringing spotty showers and a dusting of snow to the mountains. Isolated heavy showers fell over the La Canada Flintridge area producing a localized mud and debris flow. Otherwise the rain was not significant enough to cause any problems.
This morning showers continued to fall in the Inland Empire, mainly heading up into the San Bernardino Mountains. Otherwise most of the Southland is now dry. Gusty northwest winds are filling in behind this first front and this is going to make today blustery. High temperatures are mostly going to be in the mid 60's.
Tonight a second front drops into the West, reinforcing the cold air and fueling more winds. This is going to make Saturday a tad bit cooler than today. Additionally it's likely that WIND ADVISORIES will be issued for the mountains and for the high deserts. Tomorrow is going to be mostly sunny and windy. Highs will continue to hang out in the mid 60's, while overnight temperatures will be quite cold.
Sunday high pressure is forecast to build into the Southwest bringing gusty Santa Ana winds to the Los Angeles area. With a cold airmass in place we won't see a dramatic warm-up; however look for temperatures to return to the 70's Monday and Tuesday.

Light Showers, Strong Winds and Cool Temps
6:34 AM November 12, 2009
Today autumn makes a return appearance as a cold front races down the California Coast. Presently the front is moving through Central California and it will move south of Pt. Conception this afternoon and into the evening hours. Before the front arrives we're going to have partly to mostly cloudy skies with cool temperatures.
This morning painted skies signal changes to our weather. As the day evolves and the front approaches, look for increasing clouds and winds. High this afternoon are going to run about 10 degrees less than yesterday, cooling even more as the front passes.
Rainfall will be scattered and light across Southern California. Most areas will only receive a trace or so of precipitation, with a few isolated totals of a tenth of an inch. This evening snow levels will drop to around 6,500 feet with a light dusting possible on the higher peaks. WIND ADVISORIES will likely be issued for the mountains and for the high deserts.
Early Friday we'll have lingering showers, mainly against the mountains. Otherwise expect partly cloudy skies, windy conditions and cool temperatures. Highs will mostly be in the 60's. Friday night a second weather system is forecast to move into the Great Basin. Locally another surge of cool air and winds will push into the Southland overnight and this will keep conditions blustery on Saturday.
Sunday an area of high pressure will follow on the heels of the low and this could trigger a moderate Santa Ana wind event. Due to the cold airmass over the West we won't see a dramatic warm up; however temperatures will be seasonal by Monday.

Chance of Light Rain Tomorrow
6:27 AM November 11, 2009
Tomorrow we'll have a slight chance of rain as a cold front moves into Southern California late in the day. Rainfall amounts will be light with most areas receiving less than a tenth of an inch. Tomorrow evening snow levels could drop to about 6,000 feet and there could be a couple inches of the white stuff on the highest peaks. WIND ADVISORIES will be likely in the mountains and in the high deserts.
Today we're going to have partly to mostly cloudy skies as a huge volume of moisture, in the form of mid and high clouds, drifts over the Southland. One might expect temperatures to be down with this overcast, however weak offshore breezes continue to keep temperatures mild. Here in Los Angeles look for a high near 80 degrees, while the valleys push up into the lower 80's.
The clouds will thicken up tomorrow as the cold front moves down the coast. This weather system should reach Southern California late in the day, bringing a chance of showers to the Los Angeles area. It will be noticeably cooler with daytime temperatures running 10 to 20 degrees below today's mild numbers.
Friday will be a blustery day with gusty northwest winds, cool temps and partly cloudy skies. There may be an early morning shower lingering in the high country; otherwise it should be dry. A second, weaker storm, will drop into California late Friday into Saturday morning. This system appears to be dry; however it will bring in more cool and breezy conditions to the Southland.
The remainder of the weekend will be mostly sunny and cool. Monday, warmer weather returns as high pressure builds over the West.
