LA to see break from hot weather by the weekend (and maybe rain)

After a scorching start to the week, Southern Californians should feel some relief going into the weekend. 

"We're done with the heat," said Robbie Munroe, a meteorologist with the National Weather Service (NWS). “However, as we had yesterday and into today, even though it's a little bit cooler we have much higher humidities, which makes it feel almost as hot.”

Munroe said that the slight cooling trend will continue, with a 20 percent chance of  showers and thunderstorms Wednesday. Those chances jump to 30 percent Thursday.

Temperatures will hover around the 70s and 80s throughout the rest of the week, with slightly lower numbers along the beaches.

That'll be a welcome change from a week of record-breaking temps around the county. On Tuesday, California ISO was forced to issue a grid warning, when unexpected outages and congestion stressed the energy grid for about three hours. Demand reached 41,000 megawatts. With Wednesday's lower temperatures, the agency expects usage under 38,000 megawatts.

The coolest day of the week, Sunday, will also see a slight chance of showers and thunderstorms. But NWS has "a much lower confidence with that system coming through," said Munroe.

Don't get too used to it, though. The cooling trend won’t last. The NWS anticipates temperatures to bounce back to highs of around 90 degrees by early to mid next week.
