For the second day in a row, unseasonably warm temperatures will dominate the western third of the country. Record high temperatures will be challenged on Tuesday across much of California. San Francisco's high of 88 on Sunday shattered the previous record for the date by 5 degrees. A heat advisory remains in effect for the Bay Area, as high temperatures will be similar to what occurred on Monday.

Downtown Los Angeles soared to 94 degrees on Sunday, breaking the previous record of 92 degrees which stood for 95 years. Even closer to the coast, temperatures climbed into the upper 80s to set records at Los Angeles Airport and Santa Barbara Airport. Temperatures will climb slightly higher across much of Southern California on Monday, and some of the warmer locations in the upper deserts could reach the 100-degree mark for the first time this year.
