It looked to be like another great cool day on the Westside yesterday. Around noon, temperatures were in the low 70s. Then came the late afternoon when temperatures were all of the sudden hovering around 93 degrees, which was a record for UCLA, beating 89 degrees in 1990. What the heck happened? The National Weather Service says it was all in the the crazy wind we've been getting, forcing hotter temperatures as the day progressed. Basically, as wind from the north came over the mountains into the LA Basin to sea level, the air heated up in what is called "compressional heating," explained the Service. As for today and Friday, temperatures in the 90s will be found in the valleys and inland areas.
