Following mild conditions today, temperatures will trend cooler through Friday in San Diego's City Heights. Developing low pressure is responsible for the cooling trend, leading to stronger onshore flow and deeper marine layer. Patchy drizzle is possible Thursday night into Friday morning.

Conditions will warm back up for the weekend and beyond, but remain below seasonal averages, with onshore flow prevailing.

The summer solstice is this Friday at 8:54 am.
