Let’s Look At Clouds From Both Sides Now

If it looks like the clouds are boiling, just like a pot of water on the stove, it’s because the dynamics are very similar. Heat is being transferred upward through convection.

NWS EDD

We seldom get the big picture of what’s on the radar by just looking at the sky. Not today. Today is different in SoCal.

The atmosphere is unstable on the the other side of the Santa Ana Mountains, around 30 miles east of me. That’s where the radar (at the top of this entry) shows strong thunderstorms.

What’s striking in the time lapse below are the mid and upper levels of the clouds producing the storms. There are no clouds in the way blocking my view.

The heavy rain and lightning bolts are out-of-sight behind the mountains. Here, I only see the signs. Everything is moving north and will soon be gone.

Gray And Gloomy

In SoCal people look forward to these gray days as a break from our endless sunshine. An OC native I spoke to yesterday was curious if I missed rain?

Right.

I wanted to say, “You’re nuts.” I held my tongue.

When I got up this morning (OK–it was afternoon. So shoot me.) the sky was gray. Not as bad as the photo (above) from the Mt. Wilson camera… but still gray. That’s not unexpected this time of year. May Gray is a well worn California phrase.

As it turns out, what looks like typical SoCal marine layer cloudiness is anything but! There are moderate to heavy radar returns from Central and Southern California.

The NWS office in San Diego describes it this way:

SCATTERED SHOWERS AND THUNDERSTORMS WILL CONTINUE ACROSS THE MOUNTAINS AND DESERTS THROUGH THIS EVENING…WITH ISOLATED SHOWERS AND THUNDERSTORMS POSSIBLE WEST OF THE MOUNTAINS.

Even though these cells are moving in my direction it’s likely few (if any) will get here. The mountains east of us enhance the rainfall on the desert side, then stabilize the airmass as it moves back to lower elevations.

Actually, I feel gypped on days like today. Stupid attitude, but it is what it is. My mind has independently decided it’s supposed to be sunny and mild every day. I have no control over the letdown I truly feel.

By tomorrow we should be back to normal.
