Is the humidity in SD new? (San Diego, Barstow: 2013, living, bars)

[Walkthetalk]

I am not sure if I experienced it years ago but it was kind of humid when I was just there, although it didn't feel as thick as back east, where the precipitation is higher. Overall I think SD is drier but I hope not less so than years ago.

New? No, not hardly. It's just exceedingly rare. This last week makes me feel like we're living back in North Carolina.

Definitely not new. What happens in Mexico doesnt stay in Mexico.

Since I have been here for almost a decade, it is unusual to have it for this many consecutive days before some kind of dry out. Usually it would stick around for a few days at most then just fizzle.

The storms in MX creating this moisture level appear to be pretty strong this year.

Its supposedly supposed to taper off later this week...we can hope

This is 100 percent right.

It is Mexico's fault.

It's true it's been sticking around longer this year, but on the other hand, it's only been this one heat wave. Most of the summer was mild and dry, whereas in past years, we seem to get a number of shorter humid events instead of one longer one.

Its a phenomena of the Southwest known as the "southwest monsoon" because it is unique to California, Arizona, Nevada, New Mexico, Utah, etc. The "southwest monsoon" is an air current that comes up from Mexico into the U.S. and often brings rain and thunderstorms with it. For places like Las Vegas, Phoenix, Barstow, Needles, Lake Havasu, Yuma, Blythe, Flagstaff and Albuquerque, this moisture is normal.

The monsoon is active from about June through October and you get bursts of moisture that make there way up from Mexico and produce thunderstorms over the desert. Usually, the clouds, thunderstorms and associated humidity stay out in far East San Diego County, or the Imperial Valley and do not effect the city or the coast. This year, there has been a great deal of tropical convection in the western Pacific Ocean which has helped to "feed" the normal monsoon and make it more powerful, thereby, pushing more moisture over toward the coast and San Diego proper.

I'd venture to guess, though, that almost all of our October rain, if/when we get it, is Pacific in origin -- central to AK. We ain't worrying about too much moisture in October.

Interesting about monsoon & MX.

It seems to be getting more frequent to me. I'd love to see some data comparing say 1983 to 2013.
