SYNOPSIS
Weak high pressure building over the Southwest will bring dry, warm weather through the middle of next week. Late next week a trough deepening along the West Coast will bring cooler weather next weekend.

DISCUSSION
FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO COUNTIES...

A trough moving across Southern California this morning will drift east toward Arizona this afternoon. It will be replaced by a weak ridge that will bring generally clear skies and warm weather this weekend.

Early next week the jet stream will be over the Pacific Northwest with weak troughing or zonal flow over the Southwest. This pattern will bring mostly clear skies Monday through Wednesday and high temperatures close to normal. Coastal highs will be in the 70s, valley highs in the 80s, mountain highs in the 60s and 70s, high desert highs in the 80s, and lower desert highs from 95-100. Night and morning low clouds will be mostly confined to coastal areas.

Late next week the ensemble guidance is showing a deeper West Coast trough that is forecast to dig farther south toward SoCal. The 00Z models were in greater agreement than the 12Z models with the strength and depth of this trough. Its first impacts will be subtle cooling on Thursday followed by more noticeable cooling Friday and Saturday along with a deeper marine layer and blustery mountain and desert winds. There is also some potential for light precipitation with this trough next weekend.
