Weather Check: Excessive Heat Watch Issued for the Area, Temps to Break 100 in Some Neighborhoods

The National Weather Service has issued an excessive heat watch for many areas of Southern California, including the valleys and mountain areas. With a very large high pressure system building over the next few days, monsoonal moisture -- that's a plume or flow of moist unstable air channeling into a particular area -- from the Gulf of Mexico has come to the Southland. All that said, there's going to be some humidity.
Highs could break records today, including 86 at LAX, 98 in downtown Los Angles, 99 in Long Beach, 108 in Burbank, 112 in Woodland Hills, 104 in Pasadena, 88 at UCLA, 102 in San Gabriel and 88 in Oxnard.
This trend of hot air is expected to last through Sunday. The weather also has officials concerned about power outages and brush fires. The LADWP is urging customers to conserve energy where they can.
