Imperial County Weather Synopsis
Highlights...

Significant Wind Storm Possible Friday Afternoon-Night
Widespread Rain Moving In Late Friday, Flash Flooding Possible
Heavy High Mountain Snowfall

All eyes are on a high impact Pacific storm system to affect Southern California Friday-Saturday as the strong jet stream dives south to our latitude, bringing heavy rainfall capable of producing flash flooding, damaging winds, and heavy high mountain snowfall.

SYNOPSIS FROM THE SAN DIEGO OFFICE
After a tranquil weather period continuing through Thursday, all eyes turn to a major, high impact Pacific storm system which will affect Southern California Friday through Saturday. This storm will be significant, bringing heavy rainfall capable of producing flash flooding, damaging winds, and heavy high mountain snowfall to Southern California. The storm will exit the area late Saturday with dry weather returning Sunday through Monday. Additional lighter precipitation is possible by the middle part of next week

SYNOPSIS FROM THE PHOENIX OFFICE
High pressure drifting eastward over the Desert Southwest will bring dry conditions and above-normal temperatures to the region through Thursday. A rather strong Pacific weather system moving into the region will then bring a period of rain mainly focused on Saturday. Clearing skies and warmer temperatures are then forecast for the early part of next week as high pressure rebuilds over the region.
