The good news is temperatures are beginning to back off from their searing highs. The bad news is we’re in for some still-hot, sticky, sweating misery as a deadly Mexican tropical storm sends increasing humidity to Southern California.
Temperatures are expected to slowly decline in Southern California through the rest of the Labor Day weekend, but uncomfortable humidity is expected to increase, the National Weather Service said.
Temperatures hit triple-digits around the Southland Saturday, but are expected to cool Sunday with a slight chance of showers in some areas. A heat advisory will also be in effect until 10 p.m. Monday. Humidity was expected to increase 43 to 53 percent in the L.A. Basin Sunday and 30 to 40 percent inland, Smith said.
The higher humidity was blamed on moisture from Tropical Storm Lidia in Mexico’s Baja California Peninsula, she said.
While temperatures are expected to be lower Sunday, the increase in humidity will keep people sweating, Smith said.
Temperature estimates for Sunday include 93 degrees in downtown Los Angeles, mid-80s in coastal areas and mid-to-upper 80s in the valleys, she said.
They will trend downward a few more degrees on Monday before starting upward again Tuesday as humidity declines.
With the tropical moisture comes an increased chance of thunderstorms and dry lightening in the area starting overnight, Smith said.
Some storms could be heavy and cause flash flooding in burn areas, she said.
Rain could help firefighters battling the brushfire in the La Tuna Canyon area, but dry lightening could start more fires.
Dry lightning and showers are especially likely Sunday afternoon.
