Slightly cooler temperatures today as a weak low from the north pushes south. This will bring some high clouds today. But tonight the marine layer may pick up due to onshore winds. Tomorrow will be warmer in the afternoon and on Sunday and Monday, San Diegans get to enjoy the warmest days of this dry stretch. We may reach the 80's for some inland valley locations. All of that changes by Wednesday though when a colder system moves south and sends temperatures plummeting.
