The San Diego region is enjoying cooler temperatures so far this week, but a bout of fire weather is expected on Thursday.

The National Weather Service office in San Diego is predicting 35 mph offshore winds to develop in the morning and continue into the afternoon as relative humidity falls to as low as 15% in the western valleys and western mountain slopes.

“Fire weather hazards will be elevated in some locations, but critical fire weather conditions are not expected,” the weather service said.

Highs Thursday will be 83 to 88 in the western valleys and 88 to 93 near the foothills.

Elsewhere it will gradually warm throughout the week, with coastal highs increasing from the low 70s Tuesday to the low 80s by Saturday.

“High pressure will build Thursday through Saturday, bringing warmer weather and less coastal cloudiness,” the weather service said.
