textproduct: Los Angeles

SYNOPSIS

05/1201 AM.

Seasonably warm weather will continue away from the immediate coast, while far interior areas will continue to bake under triple digit temperatures all week. Along the coast low clouds and locally dense fog will develop and could linger into the afternoon in some areas.

LONG TERM (SAT-TUE)

05/232 AM.

The pattern will remain the same Saturday and Sunday. Max temps will remain 4 to 8 degrees above normal, min temps will remain 3 to 6 degrees above normal and humidities will also be above normal. This will continue the dangerous heat effects and Heat warnings (and very likely heat advisories for many non coastal areas) are currently in effect through Saturday evening with a 40 percent chc of an extension into Sunday.

The area will continue to be on the western edge of the monsoon with a 5-10 percent chance of showers or thunderstorms again focused across interior Los Angeles County mountains and deserts.

The ridge begins to break down on Monday and continues into Tuesday. This should lead to 2 days of cooling and an elimination of the need for heat products.
