Winter is still throwing one last punch at Southern California later this week, as an unusually strong late winter storm is forecast to bring potentially heavy rainfall and a chance of thunderstorms Wednesday night and Thursday. Models bring between 0.5" and 1.5" precipitation to the inland valleys.

A warming trend will take over next weekend.

After the last 2-3 storms this month managing only a few hundredths of rain here in the low deserts, I'm definitely looking forward to this wet storm. We need some relief from this weekend's 103-107 degree temperatures here so early in the season! Yeesh! A good quarter to half inch would be welcome out here.

Given the trend of the last few springs, I would not be surprised to see a few more storms in May, with a potential for low snow levels, and possibly a decent soaker in early June.

One of the more interesting things about this storm - will Thursday be warmer at the beaches than it was anytime last Friday or Saturday while the deserts were roasting? I've seen storms hit Eureka in summer before and knocking out the marine layer raising highs from the usual upper 50s/low 60s, to around 70 degrees.

You can say that again! laugh.gif

I still haven't gotten to 1/2" for 2012 (currently at 0.47"). This could very well be our wettest storm of the 2011-12 season (so far, the honor belongs to the mid-September monsoon storm which dumped 0.33" at my house).

If this front has a nice subtropical tap like they say, These totals could be underdone for my area. We had a storm like this in I believe October a few years back, An early storm, but it was very similar and ended up dumping over 4" of rain. Of course I don't expect those totals, but I would not be surprised if there are totals that were not expected. Either way, A nice storm indeed...Of course things could change for the better (wetter), or worse (Drier) before then..So we'll see!!

Conversation between two Californians and someone who does not know about California microclimates.

Non-Californian: (To Californians 1 and 2) So how did you guys enjoy the heat wave this weekend?

Californian 1: What heat wave? It was overcast, drizzly, and freezing all weekend long. Not a single peak of the Sun. It was the coldest weekend we had this entire winter/spring.

Californian 2: Oh boy, was it hot? I can't stand it. Could this be a preview of a unbearable summer?

Non-Californian: One of you is not telling the truth.

ML pushed all the way to the desert floor this morning in Palmdale. There was almost no wind, which allows the clouds to sink to the valley floor instead of being blown into haze.

Today will be one heck of a bone-chilling day. Marine layer looks at least 5000 ft deep and the cloud bases are down to 500 ft. That's a 4500 ft thick cloud layer.

Still raining here at 10 am. This is a marine layer on steroids. 60 degrees will be tough to reach today.

Picked up 0.05" of ML precip overnight. Also, I wonder if there will be reverse clearing today as the visible satellite sort of seems to be hinting at that.

Last summer we had the following:

May Gray
June Gloom
July Where's the Sky
August Disgust
September December

What's something ugly that rhymes with April?

Also, I think there was an earthquake about a minute ago. Earthquake weather?

looking towards Palmdale from Mojave, I can see that the ML isn't burning off AT ALL. It shouldn't be visible at this time of the day.

There's also some tropical moisture coming over the mountains with some nice clouds developing.

Edit: The wind is really localized, but where its happening, its strong. Lake Palmdale has had sustained winds over 35mph with gusts over 50mph all morning, while Plant 42 over in the valley just a vew miles away has been mostly calm and light all morning

This appears to be what you felt. I'm in San Diego County this morning so I didn't feel anything.

This summer will be either summer or winter, sometimes a day apart.

This cold PDO is just going to dominate again.
