May showing forecast high temperatures
National Weather Service map shows high temperatures forecast for Thursday.

The National Weather Service office in San Diego said Monday a high-pressure system will bring hot, dry weather and fire conditions to the region on Wednesday and Thursday.

“High pressure aloft will build in from the west and eventually overhead Southern California by Thursday,” the weather service said. “Strong winds are not expected, but lowering relative humidity inland will lead to elevated fire weather conditions.”

Highs will range from 80 in San Diego to 83 in Oceanside, 92 in Escondido, 95 in Ramona and Alpine, and 107 in Borrego Springs.

A cooling trend is expected to begin on Friday and continue into the weekend.
