Given recent violent weather (twinned twisters in SOCAL???) I just wanted to give you this link

www.wunderground.com (That URL is short for 'weather underground" which may give some of you oldsters a chuckle) The nice thing about this site is that it will give you info from PWS (private weather stations) like "Tom's Backyard" or "Near Old Cemetary" in addition to the official ones. Given that none of my official weather stations reflect my real local weather (official temp 88F, real temp 104F) it's nice to be able to get real info with decent granularity.

Wow. Violent weather in spring time ? That must be a first !

Most of your 'real' local weather stations will reflect weather that's hotter and gives a lower rain fall amount than is typical for an area. Why ? Because they take the 'official' temp at airports most of the time, where the concrete tends to make readings unnaturally hotter than the surrounding area. Your " example " has it exactly backwards.

Well it's not an "example" it's a real occurrence. Both airports in my area (LAX and LGB) happen to be significantly closer to the ocean than where I live (LAX is right on the beach front). The other official station (USC) for some reason is just cooler during santa anas. When I read the temp at one local PWS station I thought maybe their thermometer was off, so I checked with the next nearest local PWS and got the same reading. What we get here is something called "santa ana" winds, a downslope movement of desert air which experience "compressional heating". During santa anas, it's possible for the downslope (Los Angeles) area to be hotter than the upper desert which is the source of the air... and that's why it was 104F in my neighborhood

AFA twinned tornadoes... that's just not supposed to happen in the LA basin! Especially towards the end of May, when all of our active weather is supposed to be over and done.

Anyway, I hope the site is useful to some and interesting to most.

I figured the twin tornados reference was simply a comment on AlGore's favorite silly movie, The Day After Tomorrow.

Never heard of "compressional heating" before (so I checked it out). Pretty interseting stuff. Almost like the reverse of the adiabatic effect. According to the UCLA website cold air starts in the Mojave desert and carried by the Santa Ana winds lose humidity and pick up as much as 29 degrees F for every mile it descends down to LA.

Isn't it a little late in the year for this?

Sure its late, but bad weather can happen any time. Heck, Cleveland once got snow on May 20th.

Sometimes it rains and the wind blows and sometimes you get tornadoes.

Definitely late for us. Unlike the rest of the USA we're a Mediterranean climate and you have NO idea how different that is, even from the desert areas. That means we get "weather" only when the jet stream dips south enough to drag storms with it: our three wettest months are January, February, and March.

But MAY????
