SAN DIEGO OFFICE - SYNOPSIS
A trough of low pressure will drop into Southern California today and linger through Saturday. Today it will bring cooler and cloudier weather, some showers from the coast to the mountain crests, and areas of strong winds in the mountains and deserts. As the trough departs over the weekend, offshore flow will develop to bring clear skies and a warming trend next week.
PHOENIX OFFICE - DISCUSSION
An area of low pressure and associated cold front will sweep through the region over the next two days. The end result will be substantially cooler temperatures along with occasionally breezy conditions. Precipitation chances will be negligible and limited to only some sprinkles over the higher terrain.
The strong cool season frontal passage will generate windy conditions today and overnight. Wind gusts 28-40 mph will be possible from west-southwest by the afternoon. Skies will remain mostly clear and winds will subside overnight.
