Topline:
Summer officially starts Friday, but this week will already feel seasonably hot as a high pressure hangs over Southern California. Temperatures are expected to be near triple-digit levels for valleys and inland areas.
The forecast: Sunday will be the warmest day of the next seven days, according to the National Weather Service. Expect temperatures in the high-80s in the valleys and high-90s in the deserts until Tuesday. That’s above 10 degrees above average for this time of year.
Wednesday could hit triple-digits for areas like Palmdale.

What about the coasts? Forecasters said our beaches will say goodbye to June Gloom. Our seasonal marine layer is nonexistent for most coastal communities, except for areas like Long Beach which will see the haze linger for a few hours in the morning.
Temperatures along L-A County beaches will remain in the mid-70s for most of the week.
Is it fire weather? Santa Clarita Valley and the Antelope Valley will see low humidity around 15% through the week. Castaic Lake near the Kern County border could also see wind gusts over the next several days. These conditions can worsen drought conditions which have continued to linger across the region due to our lack of rain (about 50% of normal).
When will relief come? Forecasters said a cooling trend should develop starting Wednesday and Thursday.
