2019 California and Southwest Weather Discussion Thread

[Anti Marine Layer]

60 F to start the day for Downtown L.A which would make it quite incredible if the high was only the forecast 62 F. Same for Fullerton where it is currently 59 F with a forecast high temperature of only 61 F.

[Anti Marine Layer]

Well, ok. It's actually getting colder every hour despite the sunrise.

[Anti Marine Layer]

Nice winter weather for the unofficial start of summer, but our summer is really the middle of July to the end of October. Very few places have a cooler May average than October.

Still am thinking a cool and troughy summer with little monsoon activity, and highs below 80 some days for KCQT/KFUL and the biggest heat waves after the Fall Equinox

[Anti Marine Layer]

Rain showers are moving through pretty quickly and the deep marine layer (if you can still call it that) is pushing over the mountains into the Coachella Valley. Maybe the coldest Memorial Weekend ever.

[Anti Marine Layer]

14 hours and 9 minutes of wasted daylight. The record low maximum list will be impressive today.

[Anti Marine Layer]

Satellite loop seems to show some sort of massive eddy circulation. Notice the strong northwest flow over the outer waters and the southerly flow near San Diego.

[Anti Marine Layer]

Now there's a slight chance of snow showers for ... Julian!!! Julian! 4200 ft.

[Anti Marine Layer]

Last Christmas was 5 degrees warmer in Fullerton than it was today.

[Anti Marine Layer]

Has not been 62 or cooler for the high temperature since March 21 ... until TODAY!

[Anti Marine Layer]

Finally getting some light rain here after mostly periods of sprinkles throughout the afternoon.

[Anti Marine Layer]

Rainfall is at least moderate here now. No one else has anything to say because they are either sleeping or having Memorial Weekend picnics in the weather they enjoy the most - cool, damp, and overcast with occasional rain showers.

[Anti Marine Layer]

0.21" for Foothill Ranch so far with most of the rain now headed inland towards Temecula.

[Anti Marine Layer]

5 degrees cooler for the high today than last Christmas. Can't wait until Christmas when things finally warm up.

[Anti Marine Layer]

Holiday tea ... perfect for this chilly holiday weekend.

 

[Anti Marine Layer]

Absolutely nobody here had a single word to say about today's storm. Amazing!

I had been in L.A. for most of the day. Got rained on in the Santa Ana Canyon on the 91.

 

Also rained here a bit in the evening, and rain just resumed again around midnight. Got 0.05" yesterday.

[Anti Marine Layer]

Thunder98, Dan the Weatherman? How much rain did you get?

[Anti Marine Layer]

We have just had our first low below 50 F since March 22.

[Anti Marine Layer]

I saw some birds flying south this morning.

[Anti Marine Layer]

Phoenix may tie or break their record for the coolest Memorial Day today.

[Anti Marine Layer]

This run of cool, wet May weather in California has indeed been remarkable, but only in the light of recent years in which it has seemed like the only achievable anomalies have been warm, dry ones.

 

It's nice to see some daily low-max temp records set, and a top-20 monthly anomaly on the cool end of the spectrum for a change, but these would simply be business as usual if they were warm anomalies.

 

I can remember numerous daily record highs, both maximum and minimum, being set over the last 7 years.  How many of the 84 months over that time period do you suppose ranked in the top warmest 20?  I'd guess that more than half of them did.

 

Still, it's always nice in what seems to be a changing climate when any capability of achieving new cold records is demonstrated.

Could call it a Miracle May, especially up north. Problem is if any resemblance of summer heat decides to kick in soon, all the melting Sierra snow will flood rivers and possibly some areas of the Central Valley.

 

Also not sure why 4 out of the last 5 Mays have been well below normal. Climate change seems to favor late spring West Coast troughing and dry and warm winters. While the last 4 years were well above average overall, 3 out of 4 of them had May temperatures (at least highs) well below average.

[Anti Marine Layer]

Strong May sun battles a winter-like air mass. Downtown L.A is 68 F so far.

[Anti Marine Layer]

Still looking like coldest May in 42 years for Downtown L.A. The average high is 69.35 as of this morning and it would need to fall below 69.16 with 5 days to go to be the coldest in 73 years.

[Anti Marine Layer]

No May Gray at the beach today. Instead it's near the mountains.

[Anti Marine Layer]

No snow on Santiago Peak according to the webcams.

[Anti Marine Layer]

It is not a good day for stargazing at Mt Wilson Observatory today.

[Anti Marine Layer]

2% chance of showers for Los Angeles today, according to the NWS San Diego page. So you're telling me there's a chance!

 

[Anti Marine Layer]

Unusual situation today with mostly sunny skies to start the morning here, but a deep marine layer filling the Central Valley. However, nothing has been usual this crazy May.

[Reg]

Somewhat warmer today, clearest skies I've seen in a while.

[Anti Marine Layer]

Just went for a walk and saw some impressive thunderclouds. This May continues to amaze. Also it really didn't feel like ONLY 70 degrees out there. However, that's likely due to the strong May sun angle and the cool temperatures we have been so accustomed to lately.

[Anti Marine Layer]

Clouds from the thunderstorms were drifting NNE into the inland valleys according to satellite loop.

[Reg]

There were some clouds drifting above us early this afternoon but nothing came of it. Just a few lingering clouds over the San Jacinto Mountains to the east and nothing else now.

[Anti Marine Layer]

Low temperatures well below normal with 57 F in Palm Springs and 52 F in Fullerton this morning. Assume these should also moderate over the next couple of days as well, but starting out so low in the morning means more sun energy required to warm up the air for the high temperatures.

[Dan the Weatherman]

Thunder98, Dan the Weatherman? How much rain did you get?

 

I only managed to pick up 0.01" here in Orange with this storm. There were only a couple periods of light rain here in Orange and it seemed that most of this storm somehow missed my area.

 

I have been posting much more frequently on Weather West and I have been forgetting to post on this forum, especially this past winter and spring season. That is the reason I have been absent as of late despite exciting weather in Socal. I will try to remember to post some things on here in the future when the weather pattern turns exciting once again.

[Anti Marine Layer]

Last storm gave Lake Forest 0.22", which was one of the higher totals. It rained pretty hard for about half an hour around sunset.

[Anti Marine Layer]

San Diego is only -0.1 below the monthly average for this May so far, while most other places are far below. However, numerous days of reverse clearing probably have led to more sunshine near the coast than is normal for this time of year while the same reverse clearing pattern inland has kept them WELL below normal and much cloudier than normal and even cooler than the coastal areas. This may explain why closer to the coast, jacarandas are in full bloom while in Lake Forest look like they are half dead.

 

[Anti Marine Layer]

Downtown LA had a daytime low of 49 on Memorial Day. It is the first time Downtown LA had a low temp below 50 degrees in the month of May since 1967.

 

A bit suspicious of this, however, as I would not be surprised to see below 50 F near the beginning of May at least once every couple of years. Also, it was not included in the Daily Record Report for NWS Los Angeles. Here is a link to the full article from WaPo.

 

California cold: Record-breaking chilly and wet weather settles in, along with a hefty snowpack

 

Today Downtown L.A. reached a high of 77 F early morning, before mysterious falling back down to 69 F by early afternoon. Temperatures went back up somewhat after that.

[Reg]

Local Temecula station currently has May 2019's average high nearly 8 degrees below the 20-year normal (70.1 F vs 77.6 F).

[Anti Marine Layer]

Haze is back today with a stronger inversion and possibly a coastal eddy. It has been quite a while since we had a shallow marine layer.

 

Some models are showing that we could possibly get a ridge sometime next week.

[Reg]

It was briefly very, very windy here early this afternoon. Has calmed down to a standstill since, though.
