2018 California/Southwest Weather Thread

[Dan the Weatherman]

The Santa Ana wind never even came up here in Orange either last night or today so far, and my area is very prone to Santa Anas, too.

[Guest happ]

It isn't windy here, as well. Pleasant day. If rain is modest at least temps will come down this week.

Nice day today with pleasant temperatures. Not too cool and not too hot. We had our latest solar noon of standard time today, so enjoy the extra daylight with the sundial being nearly 14 1/2 minutes late.

[Anti Marine Layer]

Dewpoints are already going up in places like Riverside as the flow completes its U-turn. There were already a few low clouds in front of Saddleback Mountain around 3 PM with the pleasantly warm sun, but the cool sea breeze was strengthening.

Was there really a Santa Ana Wind event this morning?

Not here in Orange, anyway, but it may have blown in the Inland Empire or points further north such as Ventura County.

 

EDIT: It did blow in the Inland Empire, as Mr. Marine Layer posted below that it blew at the Riverside Airport from about 4:00 this morning to 2:00 this afternoon.

 

The flow is solidly onshore here this evening as I saw low clouds starting to come in before I ate dinner. The low clouds were slow to clear last night as well, so the offshore flow such as it was was quite weak and short-lived.

[Anti Marine Layer]

Dewpoint/humidity roller coaster ride today for places that actually did get the Santa Ana Winds today. Unlike last December's long lasting Santa Ana Wind event that caused over 300000 acres of fires, this one had to be one of the shortest Santa Ana Wind events in history.

 

Riverside Airport.

We can hope that the cut-off low will pick up some Pacific moisture besides "inside slider" oriented rainfall that often leaves us dry. The position of the trough should drop minimums below 50F given some clear nights this week.

[Dan the Weatherman]

I have had a few sprinkles here in Orange tonight. Hopefully that it is a good sign for more in the way of showers tomorrow.

[Anti Marine Layer]

Marine layer inversion looks rather weak with lots of breaks in the clouds this morning, so any rain that does fall will be convective and random.

[Guest happ]

Radar shows scattered showers in San Diego county though nothing being reported in hourly data yet. Just some scattered clouds here but it is still early so maybe the sun will help convection later. The low is forecast to move offshore tomorrow/ Wednesday so better chances for rain are possible. 

 

L: 49F 

[Anti Marine Layer]

No rain here so far. Just annoyingly cold and breezy. Unlike me, I know most people love the cooler weather.

[Dan the Weatherman]

I had a brief shower here in Orange while i was eating dinner and was enough to get everything wet. Hopefully there's more where that came from.

[Anti Marine Layer]

We had a brief shower here too. Still this is mainly a marine layer event, despite plenty of clouds in the desert and some rain in parts of Arizona that is more than we are getting.

[Anti Marine Layer]

So far Fullerton Airport and Downtown L.A. have got 0.01 while San Diego and John Wayne Airport have nothing.

[Guest happ]

A big zero for rainfall here though reports of showers in nearby Burbank/ La Crescenta last night. Oh well

Beautiful sunrise in Santa Barbara this morning

Not many clouds at all today and less windy so far.

[Guest happ]

Now we can look to next week for cold temps and maybe rain.

All that activity out in the bight but none here

It appears we will be in for some much cooler weather here in Socal if that 6-10 Day Outlook verifies. Hopefully those cooler temps are accompanied by some much needed rain and mountain snow, that will not only help with the water supply, but help the ski resorts as well.

[Anti Marine Layer]

6-10 day outlooks are far from reliable, but we would get cooler weather if it verified.

 

This storm has been disappointing so far, but I remember a cutoff low one Valentine's Day that brought much more rain than forecasted, and guess what tomorrow is. Can we have a repeat?

[Dan the Weatherman]

I picked up 0.10" here in Orange with this low last night and very early this morning.

[Anti Marine Layer]

Power outage this morning. Another cloudy morning with no rain.

[Guest happ]

Around 5:30am I watched channel 5 show radar of heavy showers moving north through Orange county/ LA but they failed to mention that very little rain was reaching the ground. Woke up several hours later looking forward to evidence

.EXTENDED DISCUSSION (Sunday THROUGH Wednesday)
  Extended forecast period consists of high amplitude upper ridging
  in the EPAC with deep troughing along the West Coast. Troughing 
  forecast to dig Sunday into Monday ushering significantly colder 
  air into Interior NorCal. Unsettled weather expected with showers 
  possible over the foothills and mountains and snow levels lowering
  into the foothills Monday. Highs in the lower 60s in the Central 
  Valley Sunday drop into the 50s Monday and Tuesday. Cold overnight
  low temperatures forecast early next week with 20s to low 30s 
  forecast in the Central Valley Tuesday morning.
 

[Anti Marine Layer]

There could be some snow in the PNW next week. Portland had some in their forecast.

[Anti Marine Layer]

Low was absolutely pathetic, and so our weather continues to be boring as the drought worsens. Therefore it's time for some more Arctic sun tracking.

 

Longyearbyen is about to experience something they have not experienced since October 26.

 

Yes, there are people who actually live here.

This has been one of the worst winters I have ever seen here in Socal in terms of boredom and dryness. 2006-07 was quite bad as well, but it was quite cold at times during that year, especially about mid January.

[Anti Marine Layer]

Longyearbyen, where dying is illegal

[Anti Marine Layer]

Here we have it. Longyearbyen's first official daylight of 2018. No clouds to obscure anything and a much better webcam than Barrow. Look at that sunshine on top of the hill just four minutes after solar noon.

 

 

It won't be until March 8, however, that sunshine reaches the town.

 

For us, we have reached just over 11 hours of daylight today. Still a few clouds left from our low pressure system, but they should not last too long, with offshore flow developing.

Last winter it basically stopped raining around mid February. I've recorded less than 3 inches in nearly a full year's time since then.

That's right, March onward was very dry except for one storm in early May. It has been a very abnormal long stretch of dry weather we have been experiencing. In years past, an early end to the rainy season would often lead to at least some storms starting in October or November of the following year, as opposed to just staying dry all fall.

 

Something different is going on in our weather patterns than what we used to see in the recent past, and this pattern seemed to really begin in earnest around 2012-13.

We appear to be in uncharted territory but I hope rainfall occurs before the rain season comes to an end or that we benefit from the monsoon this summer. At least the reservoirs are full.

There's the potential for some of the coldest temperatures of winter next week

 

74/ 54

 

 

[Dan the Weatherman]

Let's hope this cold air is accompanied by some moisture for some very beneficial snows in the mountains!

 

Since this cold pattern is coming later in the year with a higher sun angle and longer days, it probably won't get as cold here in lower elevation parts of Socal as it did in January 2007.

[Anti Marine Layer]

Cool start to what should be our last warm day in quite a while. Hopefully tomorrow night's system is able to bring some measurable rain.

[Anti Marine Layer]

For Monday, partly cloudy with a chance of showers in the morning, then mostly sunny in the afternoon. Then in the evening partly cloudy again with a chance of showers before becoming mostly clear.

 

Why does the chance of showers return in the evening?

 

I'll be amazed if we can get at least 0.05 inches somewhere.
