LOS ANGELES -- Offshore winds are forecast to clear the skies and push Southern California temperatures to about 90 degrees in valley and inland spots on Sunday.
The National Weather Service, which earlier issued red flag wildfire warnings and fire weather watches for inland and mountain areas, canceled them overnight. They may be reissued for Monday, when the relative humidity is expected to drop below 10 percent at times.
The day should start out clear, except for some morning low clouds and fog near Long Beach and northern Orange County beaches. Beach-area highs are forecast to be in the lower and mid 70s.
On Monday, beach highs could top 80 degrees in spots.
In the valleys, winds out of the northeast will be blowing about 15 mph Sunday, eventually backing to the north by Monday. Localized gusts could reach about 35 mph in spots.
In the mountains and below passes, the wind is forecast to blow at 15-25 mph Sunday and Monday.
The balmy weather should continue through Tuesday, when highs are forecast to be in the upper 70s at the beaches and the upper 80s in the valleys and inland areas.
Wednesday should be cooler but sunny, then increasing clouds Thursday night will bring a 20 percent chance of rain -- snow at the highest elevations -- by early Friday, according to the NWS.
An upper-level high pressure system over California, coupled with surface high-pressure over the Great Basin, is responsible for the offshore airflow and warm, dry conditions.
The red flag warnings and fire weather watches were canceled because NWS models indicated conditions just shy of warning levels -- gusts exceeding 35 mph, with relative humidities less than 15 percent, persisting for more than six hours.
