Is there an exact reason why the past few days were so hot? I only know that the hot air from the Santa Ana winds blow down. Did something happen far away that caused the air to blow here more than usual?

Remember the France heat wave of 2003? It killed 14,000 people.

Well, the French have never been able to figure out how to deal with something unexpected. We're having a heat wave. Happens. Deal with it as best you can. Despite the extremes, it's not at all uncommon to have a week of heat like this. No solar flares. No earthquake waiting to happen. No conspiracy. Mother Nature has California heart burn. That's all the explanation needed for the next couple days.

Wait! Those fans along the I10 between Cabazon and Palm Springs. THAT'S IT!!

Every year between September and November there are generally 2-3 heatwaves that are blisteringly hot and terribly dry. The humidity today and for the rest of the week is something else

Good response & funny!

We always get heat waves during autumn in California. There really hasn't been that much wind with this current heat but the 'santa ana's' usually begin in October.

The best text explaining current and future (next few days) weather is called the "Forecast Discussion" from the NWS. It is the "horses mouth". The meteorolgists explain what is happening, what the models indicate, and why the meteorolgical conditions are what they are."
Area Forecast DiscussionThis National Weather Service product is intended to provide a well-reasoned discussion of the meteorological thinking which went into the preparation of the Zone Forecast Product. The forecaster will try to focus on the most particular challenges of the forecast. The text will be written in plain language or in proper contractions. At the end of the discussion, there will be a list of all advisories, non-convective watches, and non-convective warnings. The term non-convective refers to weather that is not caused by thunderstorms. An intermediate Area Forecast Discussion will be issued when either significant forecast updates are being made or if interesting weather is expected to occur.
National Weather Service Text Product Display

Here's some text:
"NATIONAL WEATHER SERVICE SAN DIEGO CA 230 PM PDT TUE SEP 28 2010 .SYNOPSIS...AN UPPER LOW SOUTH OF SAN DIEGO WILL DRIFT NORTH OFF THE COAST THROUGH SATURDAY. THIS WILL BRING VARIABLE CLOUDINESS...COOLER WEATHER AND CHANCES OF SHOWERS AND THUNDERSTORMS. PATCHY MARINE LAYER CLOUDS WILL BECOME MORE EXTENSIVE NEXT WEEK. && .DISCUSSION...FOR SOUTHWEST CALIFORNIA INCLUDING SAN DIEGO... ORANGE...SOUTHWEST SAN BERNARDINO AND WEST RIVERSIDE COUNTIES. .SHORT TERM (REMAINDER OF TODAY-FRIDAY)...THERE WERE LOTS OF MID TO HIGH LEVEL CLOUDS THIS MORNING WITH A FEW SPRINKLES IN SAN DIEGO COUNTY. EARLY AFTERNOON AIRCRAFT SOUNDINGS INDICATED THAT FAIRLY STRONG ELY WINDS CONTINUED THROUGH THE MID LEVELS. OFFSHORE GRADIENTS FROM THE N AND WEAK ONSHORE TO THE E WITH ONSHORE TRENDS. A WEAK UPPER LOW CENTERED OFF THE COAST OF NRN BAJA WILL DRIFT N TO OFF OF PT CONCEPTION BY SATURDAY. MOISTURE CIRCULATING AROUND THIS LOW WILL BRING VARIABLE CLOUDINESS. THE CLOUD COVER AND LOWER HEIGHTS WILL MAINTAIN COOLER DAYS. HOWEVER...THERE WILL BE WARMING IN THE FAR INLAND VALLEYS...MOUNTAINS AND DESERTS AS THE WIDESPREAD CLOUD COVER DECREASES......." and it goes on for a few more paragraphs.
