San Diego weather: Chilly mornings but slightly warmer afternoons ahead
It’s going to be a very cold night tonight into Monday morning, with overnight lows across portions of the valleys dropping into the upper 30s to low 40s, mountain areas possibly falling below freezing, and coastal communities dipping into the mid to low 40s.

A weak surge of Santa Ana winds will develop overnight and continue into Monday morning, with northeasterly offshore flow producing mostly sunny skies, 10 to 30 percent relative humidity, and 25 to 40 mph gusts through the passes, canyons, and foothills, drying conditions and slightly warming temperatures. Enjoy the nice day ahead!

Looks like the rest of the week will stay dry through the end of the month, with weak high pressure hanging out over the region.
