Higher humidity could bring rain to local mountains, valleys
A flow of monsoonal moisture and increased humidity could bring some rain to parts of Los Angeles, and it could be heavy in some mountain and valley areas, the National Weather Service said.
The weather pattern means a 30% to 40% chance that thunderstorms will develop over the San Gabriel Mountains and Antelope Valley through the afternoon and evening, forecasters said.
Because any storms are likely to be slow-moving, the weather service has issued a flash-flood watch for the areas, along with the mountains of Ventura County, from noon through Friday evening.
“There could be some pretty heavy downpours associated with these storms,” meteorologist Scott Sukup said. The San Gabriel and San Fernando valleys may also get some rain.
As with any thunderstorms this time of year, there could also be dry lightning strikes, Sukup said.
Temperatures will stay a few degrees above normal for the time of year but lower than during the recent heat wave, forecasters said. The weekend is expected to be slightly cooler.
Highs today will be in the lower 80s at the beaches, the low 90s inland and low 100s in the valleys. Downtown Los Angeles should see a high of 92, the weather service said.
