Meteoranalysts forecast on Sunday that summer heat will return to the region after an unusually chilly weekend in June in much of Southern California, while the first monsoon activity of the year will likely come over deserts and mountainous areas.

Monday’s first heatwave is set to raise temperatures multiple degrees above normal, to 83 in Downtown Los Angeles, 94 in Palmdale and 100 in Woodland Hills, said David Gomberg, a weather expert with the National Weather Service’s Oxnard Bureau.

The rise in temperature is likely to be felt on Monday, June 20, as downtown will be 10 to 15 degrees warmer than Sunday, said meteorologist Brian Adams of the National Weather Service.

On Tuesday, the first day of summer, the heat should ease a little, and stay a little closer to the coast in the 70s and 80s, but it will stay inland and in the valleys of the region for the best part of the week in the upper 80s or 90s.

Up inland, high temperatures are also forecast in the mid-90s, with some areas probably reaching 100 degrees, Adams said.
