[Anti Marine Layer]

Nice day today. Hoping to see some measurable rain for Tuesday.

[Anti Marine Layer]

Sunny this morning over Orange County while many other areas have marine layer clouds.

[Anti Marine Layer]

Desert is cooler today due to a marine layer trying to push through the Banning Pass.

[Anti Marine Layer]

Plenty of sunshine today despite the large eddy and deep marine layer. However, it looks like there will be more clouds tonight.

 

Even the desert has a chance of showers and thunderstorms on Tuesday and maybe Wednesday.

[Guest happ]

Despite the scattered clouds/ wind the longer daylight allowed the temp to finally reach 70F late this afternoon. May showers would be extra nice this week.

[Anti Marine Layer]

Clouds are increasing early this evening and the breeze is blowing steadily. Strong late April sunshine made the temperatures feel warmer than they were. Looks like tomorrow could be cooler before really dropping by Tuesday.

[Anti Marine Layer]

Looking like a classic reverse clearing day today. It's the last day of April and DWTS premiere is tonight.

[Guest happ]

The cold cut off low is definitely contributing to a very chilly day so far. Reports of very light/ trace to 0.05 rain scattered about SoCal.

 

Currently: cloudy/ 63F

 LAS VEGAS, NV  CLOUDY    69  30  23 NE7       29.84F                 

[Anti Marine Layer]

_{Marine layer clouds have the most clearing near the coast, but thickening high clouds are moving in on top of them.}

[Anti Marine Layer]

Marine layer clouds are aching to push over the mountains into the Coachella Valley. By tomorrow morning, they probably will. They won't make it very far once they hit the dry desert air.

Light rain in Fullerton. Still a chance to get something measurable before May begins.

[Anti Marine Layer]

Last May started out warm/hot and then temperatures took a nose dive. Looks like the opposite this year.

That's a 37 degree drop in 2 days!

If 37 degrees is not a big enough 2 day drop, how about 40 degrees?!

 

Finally, a place that's a little more dynamic...

Good old California micro-climates.

[Anti Marine Layer]

Rain has begun. Not just a marine layer drizzle.

[Anti Marine Layer]

0.29" so far for Foothill Ranch.

 

Record low highs are not out of the question for today. Savor winter while it lasts.

[Anti Marine Layer]

As I remember last year, the May 7 storm brought the coldest day ever recorded in the month of May to a few areas away from the coast. Snow levels were about 4000 ft.

 

For this one, snow levels are 5500-6000 ft., but it looks like coastal areas could be colder than last year. Sea surface temperatures are just slightly below normal. Last year they were above normal.

[Guest happ]

It is dark/ gloomy out there but still dry here. Yesterday NorCal experienced thunder showers. Hopefully it will rain here as well.

[Anti Marine Layer]

Not very likely, but possible today's highs will have occurred at 12 am this morning in some places.

[Guest happ]

Satellite shows a circulation of sorts of the mostly stratiform clouds. Very cold for late morning.

 

55F

[Anti Marine Layer]

Another reverse clearing pattern trying to set up with something even colder than a marine layer.

[Anti Marine Layer]

The cloud leakage has begun.

 

[Anti Marine Layer]

57 F right now in Las Vegas. Keep in mind that this is supposed to be a hot desert with global warming making it hotter each year.

[Anti Marine Layer]

Based on the current temperatures, it should be completely dark by 5:30 PM.

Today would be considered a cold day in mid-winter. Too bad rainfall was pathetic but convective activity tomorrow could produce better results.

0.29" so far for Foothill Ranch.

 

Record low highs are not out of the question for today. Savor winter while it lasts.

 

It only rained just enough last night to wet the ground here in Orange, but nothing has fallen here today.

[Anti Marine Layer]

If I could only see the day of the month, I might be saying Happy New Year today.

 

[Dylan]

We picked up over 1/10th of an inch in Santa Barbara today.  Some of the Mountain areas in Santa Barbara and Ventura Counties picked up over .5 inches.  

[Anti Marine Layer]

Rain is falling, but it's stratiform and not cumulonimbiform, which I would prefer over the stratiform.

 

Once again Lake Forest is one of the areas with the most rain, being near the Santa Ana mountains.

 

Snow appears to be falling in the San Bernardino Mountains and even Palm Springs is overcast this second day of January, I mean May.

[Anti Marine Layer]

Got a little May Gray in the place where people go to get away from the May Gray.

Oh, the weather outside is frightful
But the fire is so delightful
And since we've no place to go
Let it snow, let it snow, let it snow

Man it doesn't show signs of stoppin'
And I brought some corn for poppin'
The lights are turned way down low
Let it snow, let it snow, let it snow

California was burning down last Christmas and everyone was stressed out, so now is the appropriate weather to enjoy some Christmas carols.

[Guest happ]

Managed to record a measly 0.02 overnight but May showers are generally quite limited in SoCal. North Pacific storms lose most if not all of the dynamics to produce rainfall and the monsoon hasn't developed yet. Noteworthy are the very cool maximums; 20 degrees below average yesterday. Similar readings during winter would have produced maximums below 50F; quite rare. At least we are getting in on "weather" that normally escapes us this time of the year. 

 

Storm: 0.03

Wow, snow in May in Southern CA!

[Anti Marine Layer]

Northerly flow, inversion should be weak to non-existent, low moving out, so what's holding together the deep marine layer?

 

Then, I should not complain about marine layer as they'll probably get some severe weather and tornadoes moves past the Rockies.

The weather roller coaster should be heading up, up, up in the next few days if they're correct.

[Jesse]

Wow, snow in May in Southern CA!

 

Probably not that unusual historically.

 

In Mr. Marine Layer's dream world where global warming is even faster and more severe it would probably never happen, though.

[Anti Marine Layer]

Reverse clearing again today. When the sun does come out, the warmth reconvects the clouds and it's gloomy again within a few minutes. Still thinking inversion will not form at a lower height in until tomorrow afternoon.
