California’s Central Coast | Everywhere

Dave Hovde

Storm system arrives Tuesday

A low pressure system will drop into the central coast Tuesday. Rain will arrive earlier in the day along the north coast and moving south into Santa Barbara county during the evening. S to SE winds increase during the day to 15-25mph. For most of the area the significant rain will wait until afternoon. The system is part of a low pressure core that will actually keep rain in the forecast Wednesday and early Thursday.

Showers Saturday with more potential for heavier rain next week

Another cold front is on the way for the Central Coast this weekend. This front looks to touch off a few showers but it will not be as strong as the storm earlier this week.

I light some folks will stay dry and even the high side of the system probably produces .25″ of rain. The rain could start early in the say, but the highest opportunity for showers will be the afternoon, by evening the system will have moved on. Sunday looks dry.

Rain tapers off tonight

The cold unstable air associated with this storm system is moving over the Central Coast, this produced some pockets of heavy rain and isolated thunderstorms Thursday afternoon and evening. This activity will slowly wane tonight into Friday morning. Not only will the rain taper off but the winds which produced advisories thru 9pm will also slow, a little. Breezy to windy conditions are expected again Friday but the winds shift out of the NW.

Storm system will continue to bring rain into Thursday evening

The two day storm even still has hours of potential rainfall to deliver to the Central and Southcoast. Rain will continue with periods of moderate to heavy showers. On and off rain will taper off tonight. Over the course of the day .25-2″ of additional rain may fall over the area.  Highest rain accumulations will take place on SW facing slopes and in parts of the Santa Ynez mountains.

An atmospheric-river system aimed at California

A rain system with .75-3″ potential of rain for the Central Coast arrives locally Wednesday with rain rates of .30-.50″ per hour. The storm will peak Wednesday night into Thursday morning.

Models are in agreement that the Central Coast will see some rain Wednesday morning that will bring scattered showers throughout the afternoon intensifying later.

Rain returns mid-week with significant potential

This week will start off with very pleasant weather but change Wednesday.  Offshore winds Monday produced very nice skies, but already Tuesday we’ll be watching a front moving down the coastline.  I don’t think it gets here most of Tuesday but we’ll see some transitional weather with increasing clouds especially later in the day.

Rain could begin as light showers as early as Tuesday night and become more intense Wednesday morning, but very likely in the evening and overnight and continuing Thursday.

Rain into the overnight hours with improvement Thanksgiving Day

Rainfall totals through Thursday morning can be expected to be about 0.25 to 0.75 inches across SLO and SBA Counties, with local totals of 1 to 1.50 inches in the foothills and mountains. Isolated totals up to 2 inches are possible across the higher terrain of northwestern SLO County.

Wednesday rain likely for much of California

One of the busiest travel days of the year will be greeted with some potentially challenging conditions. Rain is likely Wednesday. Timing for the Central Coast puts the bulk of the moderate rainfall over the area in the afternoon into the late evening and early overnight hours with the main band moving from the NW to the SE.
Strong south winds will also develop ahead of the frontal boundary and locally winds of 15-30mph should peak in the afternoon into the early evening.

Wednesday rainfall could make travel tricky

The weather pattern is about to make a major shift. The dry weather of the last several weeks will quickly turn wet on Wednesday with rainfall over much of the state of California. For the Central Coast showers may greet us early Wednesday but the bulk of the moderate rainfall looks to begin Wednesday afternoon thru Wednesday evening before becoming more showery into Thanksgiving morning.
Rainfall totals will have a rather wide range from under .25″ for some inland location to more than an inch along the coast.

Rain in the forecast for next week

Smoke in the skies will linger into the weekend as there is still new smoke being produced and the predominant flow is from the north bringing smoke into SLO and to a lesser extent Santa Barbara county from the Camp Fire. The time of year is also a factor, cooler temps allows the smoke to hug the ground and also the winds are currently light not allowing for much mixing.

Our local weekend will feature temps dropping into the 70s for most with 60s at the beaches with a mix of high clouds and more low clouds developing.

Daytime highs will cool a bit as onshore flow returns

We’ve seen extended offshore flow around the entire state which set the stage for the numerous wildfires. The good news is that the offshore winds are fading and also the pace of the wind is slower. This will allow a mix of low clouds and high clouds to come across the area thru the weekend for cooler conditions. There is also ample smoke and haze from the Camp Fire since the winds are NW we get some transport down here to the Central Coast.

Fire weather improves with rain prospects around Thanksgiving

High pressure is still in the area but the winds driving the dangerous fire weather conditions are improving. Red flag warnings for Southern California have been allowed to expire. Thursday and Friday will still be warm for much of the area and as the weekend arrives so does onshore flow and the return of some night and morning marine layer near the coast.
More mid to upper 70s in the SLO interior valleys with 70s and low 80s in the coastal valleys for Friday. The beaches will be mostly in the mid to upper 60s and lower 70s.

Temps look warm mid-week but a pattern change is in sight

Highs Wednesday should be in the upper 70s and some lower 80s for the coastal valleys with inland valleys in the mid 70s and beaches also in the mid 70s. Wednesday should be the warmest day of the week, it is largely dependant on the offshore winds but the amount of high clouds are also a factor. It’ll take mostly clear skies to stretch into the 80s I think. Thursday looks similar but probably about 4 degrees cooler across the board. Friday also sees another 2-5 degree temp drop as the ridge starts to break. But I see big changes later next week.

Dangerous fire weather conditions continue

Temperatures locally will be in the 70s inland this week with coastal valleys in the mid 70s to mid 80s thru Wednesday with the beaches in the low to mid 70s.  Skies will remain mostly clear however smoke haze will be a concern until more fire suppression takes place.

Very dry air will result in very cold lows inland and lingering fire concerns

Offshore flow has dominated California weather over the last couple days with devastating results. That will continue into early next week. The pace of the winds will slow a bit tonight into tomorrow but an invigorated offshore event picks up Sunday morning-Tuesday. Across Southern California the Red Flag Warnings have been extended into next week.

Freezing conditions inland linger into next week

The dry air and clear skies will allow temps to drop like a rock tonight in the interior valleys where lows in the low 30s or even upper 20s are possible. Freezing mornings may take place well into next week. Also a pattern change later this month could produce rain around Thanksgiving.

Warm daytime highs with offshore winds but also freezing nights for some

For the Central Coast some localized gusty winds could hit 20 but there is no advisory. The general winds offshore in the night and morning hours should stay under 20 for most. Winds will turn back in the afternoons over the next few days. Highs will be much warmer than average with coastal valleys in the upper 70s and lower 80s Thursday thru the weekend with beaches and interior valley highs in the mid to upper 70s.
