Storm’s End Brings Showers, Humidity : Weather: The remains of Hurricane Hilary are expected to push clouds and warm rain into the Valley through Thursday, with highs in mid-90s.

The remnants of onetime Hurricane Hilary began drifting over Southern California on Tuesday, dropping warm, scattered showers that are expected to continue for the next couple of days.

“The showers and thundershowers will be brief but sometimes intense,” said Guy Pearson, a meteorologist with WeatherData, Inc., which provides forecasts for The Times. “Most areas around Los Angeles probably will see some measurable rain [today] but not a lot of it.”

Pearson said Hilary, which grew to a full-fledged hurricane off the west coast of Central America on Sunday, started losing intensity as she moved steadily north over ever-cooler ocean waters. By Monday, she was downgraded to a tropical storm, and by Tuesday, she was only a tropical depression.

Centered Tuesday afternoon off the shore of central Baja California, the spinning low-pressure system that remained was expected to pump moist tropical air into Southern California until Thursday, before dissipating.

Pearson said the showers should taper off by Thursday afternoon, with mostly clear skies through the weekend after a few morning clouds along the coast.

It will remain warm and muggy through Thursday, with high temperatures in the Los Angeles Basin ranging from the mid-70s to the mid-90s during the day, followed by overnight lows in the mid- to upper 60s. Daytime highs will be about the same Friday and Saturday, but the weather should be more comfortable as the relative humidity and overnight temperatures drop.

Thunderstorms could drop as much as a quarter-inch of rain on parts of the San Fernando Valley over the next two days, Pearson said. High temperatures should range in the mid-80s to low 90s across the Valley, with lows ranging from the mid- to upper 60s.

On Tuesday, northern Los Angeles County was hit with pounding rain. High winds and dust storms brought visibility down to 15 feet along portions of the 138 Freeway, between Gorman and the Antelope Valley, making driving treacherous, according to the California Highway Patrol.

Mostly sunny skies and seasonable temperatures are expected through the weekend in the San Fernando Valley and High Desert, forecasters said.
