STUDIO CITY (CBS) — The high pressure that has dominated our forecast for the past several days continues to be relentless for our desert and valley cities. Now, however we are adding in higher humidity and it is for this reason the National Weather Service issued an excessive heat warning for LA County.
The heat index will range from 100 to 105 and heat exhaustion is very possible. The added humidity means there is also a chance for thunderstorm Wednesday afternoon and continues through the rest of the week. In fact, the forecast models show the best chance for development will be Thursday afternoon, so stay tuned.
Otherwise we continue with temperatures running well above average. By the weekend we will see the return of the on-shore flow, so that should make things feel better for valley cities that have been sweltering. We will also see the marine layer returning…but probably not until Sunday.
Beaches -low to mid 70s
Basin – low to mid 80s
Valleys – over 100
Deserts – low 100s
Mountains -mid 80s
