A "significant warming trend" is hitting L.A. starting Monday, with temperatures set to escalate through the week. The heat wave will peak Thursday, with triple-digit temps in the valleys and 91 degree heat predicted for the downtown area. "It's going to be a long week," National Weather Service meteorologist John Dumas told LAist, adding that there would be "very slight cooling Friday and Saturday."

There is currently a heat warning in place in the Antelope Valley and heat advisories in place in the mountains and valleys, according to Dumas. There will also be a chance of afternoon showers (and potentially even thunderstorms!) through the week due to monsoonal moisture in the air. "The clouds will be nice for finding some shade, but the humidity that comes with it may make things a little uncomfortable," Dumas said.

Temperatures today are expected to hit 85 degrees downtown, which is slightly above average, and will continue to rise through the week. Pasadena will be getting up to 98 degrees by Thursday, Burbank is slated to hit 94 degrees, and that furnace box of Woodland Hills has a forecast of 102 degrees for that day.

The valleys, as per always, will be hotter than the downtown area through the week, and the coast will be substantially cooler than both, though even the beaches could hit the low 80s by Thursday.
