SoCal heat wave continues one more day, then midweek cooldown will bring relief

LOS ANGELES (KABC) -- The hot and humid heat wave will continue for one more day in Southern California but we're in for some relief with a serious temperature drop by midweek.

The heat is bringing in monsoonal moisture, leading to higher humidity levels and a chance of thunderstorms to the mountains.

When will the heat wave end?

The temperature starts dropping Tuesday, and then a substantial cooling trend will kick in Wednesday, with temperatures plummeting more than 20 degrees from their heat-wave highs.

Monday, however, Los Angeles and Orange counties will continue to be hot and humid, with a slight chance for thunderstorms. Monday will see a high of 102 but that cooldown means a high of just 79 degrees by Wednesday.

Brutal heat continues in the valleys and Inland Empire, reaching 106 degrees on Monday. The region can expect a cooldown Wednesday when temperatures are projected to be in the mid 80s.

Beaches on Monday will reach about 85 by the afternoon, dropping to the low 70s by midweek.

There's a 30% chance of thunderstorms in the mountains on Monday amid humid conditions, with a high around 79.

The desert areas will stay above 100 on Monday, but will cool down to the 90s and upper 80s later in the week.
