Beautiful weather today, but tonight will be chilly. Not as cold as last night, with 40s and 50s from the coast to our inland valleys but still cold for San Diego standards.

Temperatures will be in a warming trend into the weekend, adding another 5 degrees on Thursday. Temperatures will peak on Friday and Saturday with some of inland communities potentially heating up to the low 90s and mid 80s for coastal communities.

Santa Ana winds will develop late Thursday, lasting through Saturday morning. The winds will be weak ranging from 20 to 40 mph, but it will elevate fire danger, and it will lead to drier conditions. Relative humidity could average between 10 to 15%.

High pressure will shift to the east, replaced by a trough and cooler weather for next week. The marine layer will return will clouds at night and morning from the coast to our inland communities starting Sunday.

Thursday's Highs:
Coast: 70-76°
Inland: 75-80°
Mountains: 65-72°
Deserts: 75-83°
