2018 California/Southwest Weather Thread

[Thunder98]

It's going to be much cold and windier tomorrow. Only 51F in Santa Maria with a slight chance of rain with potential 40 MPH gusts. It will feel a lot like Wyoming for the next several days.

 

[Anti Marine Layer]

Marine layer is slow to develop this morning but it might still arrive post sunrise and if it doesn't it's pretty sure to come racing in late afternoon before sunset, but by tomorrow morning any inversion should be a thing of the past.

 

We had record heat last fall with the sun at the declination it is at right now, so it seems fitting that we have some record cold as the sun will reach over 45 degrees above the horizon for the first time since last October tommorow.

 

Trees have already been confused by the warm fall and winter so far, with many still having leaves from last year. Hope to get some wind to get rid of these leaves and if the cool weather sticks around it could be a late bloom this spring.

Frost/ freeze warnings for a good deal of SoCal starting Tuesday.

They're still forecasting mostly sunny with a chance of showers tomorrow morning. I've seen times before where it rained with a clear sky directly overhead, but it was still at least partly cloudy.

"a 520dm 500mb upper low" 

[Anti Marine Layer]

Some random and sparse low clouds are forming, but nothing close to a solid marine layer. Inversion must already be weak.

[Anti Marine Layer]

Sitting out in the sun, it feels pretty hot, but once that afternoon breeze kicks up the cooler air should be noticeable.

WeatherUnderground is forecasting a low of 26* Monday night here in Modjeska. 

 

I sure hope they're wrong, I don't want to be covering plants.

[Anti Marine Layer]

Mostly sunny today and completely free of haze and smog, with only random low clouds at times and it got pretty warm for a while, but the wind really picked up and cooled things down in the afternoon. Whatever marine layer develops won't have much of an inversion, if any, to hold it together. Some waterspouts would be nice.

[Anti Marine Layer]

It was starting to sprinkle outside. Otherwise it looks to be a very chilly day tomorrow by California standards and maybe, just maybe, we can get some measurable rain out of it.

Doing errands I was thinking about your post while observing tall sycamore street trees and down along arroyos. A leafless tree growing near fully leaf sycamores but that seems to be normal. Sadly others are dying from beetle infestation.  Bauhinia & ornamental pear are in full bloom now.  The foothills are still green but the grass will die away early this winter; so it seems. 

 

Sunday: 69/ 51

[Anti Marine Layer]

Fullerton only got down to 52 overnight and Julian down to 32. Sure does not seem cold enough for snow levels at 1500 feet. Also dewpoints have dropped into the teens just recently, which pretty much ends our chances of any significant rain.

[Thunder98]

Snow shower in low mountains west of San Luis Opispo and Avila Beach. Snow in Paso Robles!?

 

 

[Anti Marine Layer]

All clouds have been pushed well inland with Coachella Valley currently having more clouds than us. The wind is blowing and my neighbor across the street is in his shorts and light sweatshirt washing his car. I don't understand how some people never feel cold.

[Thunder98]

Rare snow flurries fell in the Atascadero area!

I love formation of cumulus mediocris within the cold trough. Windy here off and on; now mostly cloudy. 30's are a real possibility tonight.

@SoCalWXwatcher

[Guest happ]

Santa Maria will likely see lows in the upper 20's tonight.

 

Did you get some freezing temps earlier this winter?

Temperatures did dip down to 29F in December 22nd and 32F on the Winter Solstice

[Anti Marine Layer]

Mostly sunny with a chance of showers seems to be accurate as there are dark clouds in front of the Santa Ana Mountains, but the rest of the sky is mostly clear. There were no clouds at all this morning, however.

 

I still like this sort of weather more than the June Gloom. Today is cold and windy, but there is sunshine and the air is crisp and clean.

 

On a June Gloom day, it's overcast and depressing and the dampness makes it feel colder than it is, and any walk will leave you soaked in cold sweat. Also inversions ensure bad air quality.

Brisk morning here in Modjeska

 

[Anti Marine Layer]

Cold this morning, but at least it's not windy.

 

Yesterday had a high of 61 F at the Fullerton Airport. We had quite a few days colder than that last winter, including some during the last week of February.

[Guest happ]

Coldest minimum of winter @ 41F here and 30's widespread.

Ice in Rancho Bernardo this morning

Cold this morning, but at least it's not windy.

 

 

I would have preferred a little wind with the low temps.  It might have mitigated the leaf burn I've got on some of my more tender plants.

[Anti Marine Layer]

Now next week's system does not look to be a significant precipitation producer, but it looks like we will stay below normal for quite some time.

[Guest happ]

Overnight clouds diminished projected minimums but chilly nonetheless and looks to stay cold for a while.

 

L: 44 * correction

[Guest happ]

Relatively cold and dry into next week. Definitely a taste of winter minus rainfall.

[Anti Marine Layer]

None of the forecast discussions are relating the sudden stratospheric warming event to our cold weather. Portland is getting plenty of snow, similar to the UK.

[Anti Marine Layer]

Some wet stuff fell from the sky overnight here.

[Anti Marine Layer]

Despite the cold weather, this winter continues to be boring in terms of rainfall totals. For that reason, not many people are posting here, while the PNW thread gets 100 or more posts a day.

 

 

Today's sunset is 5:42 PM, which is a full hour later than the earliest sunset last December 4. On that day the fires started. The sunrise that day was 6:39 AM, while today's sunrise is 6:26 AM. Last time we had a sunrise of 6:26 AM, sunset was at 4:45 PM. Sadly, there's not much more interesting things to talk about.

The position of the trough limits access to Pacific moisture. All these upper level lows drop temps but not water.

We need this whole pattern to shift westward to off the coast so we are on the eastern side of the trough as opposed to the western side. Only then will the storms have the over water trajectory that would bring more significant rains to the area.

[Anti Marine Layer]

We need some rain to move latitudinally southward and longitudinally eastward so that we can get some significant precipitation very soon.

 

It's just mostly sunny, cold, and windy.

[Guest happ]

Definitely the coldest temps of winter w/ some agricultural concerns esp in the Central Valley.

 

Friday: 57/ 42 [coldest mean]

[Anti Marine Layer]

It got very windy this afternoon. Six straight days of below normal temperatures today with the offshore flow not developing.

[Anti Marine Layer]

We could actually get some measurable rain next week, but I am not counting on it.

[Dan the Weatherman]

Chances are looking better than they have for a good part of this winter. NWS actually has 60% PoPs for Monday night here in Orange County, a forecast I have not seen much at all this season.

[Guest happ]

Hopefully it will rain this week. The most significant factor has been the cold temps. Strong ridging in February followed this winter's warm pattern but positive departures ended abruptly. Frost was widespread this past week in Socal for the first time this year.

 

Saturday: 62/ 41

[Anti Marine Layer]

Warmer today with some places possibly reaching 70 F for the first time in a while, but that cool afternoon breeze is kicking up and the warmer weather won't last long. I'm enjoying the warm sunshine for now and hoping we can get some beneficial rain this week rather than just annoyingly cold and windy weather.
