SYNOPSIS

04/251 AM.

Mostly clear skies, dry conditions, a general warming trend and periods of offshore winds are likely through the week. Warmest and windiest conditions likely Friday-Sunday.

LONG TERM (SAT-TUE)

04/251 AM.

Ridging and offshore flow will continue over the weekend. While There will be canyon winds each morning there is only a 30-40 percent chc that they will reach low end advisory criteria. Skies will be mostly clear through the period. Max temps should bump up another 2 to 3 degrees Saturday and then change little on Sunday. Weekend max temps will be in the lower to mid 80s for almost all of the csts/vlys or 5 to 10 degrees above normal.

A high hgt dry upper low forms under the ridge and aporaches and moves over Srn CA during the Mon/Tue time frame. It should have little effect on the sensable weather. The more important factor will be the weakening of the offshore flow. There should be enough to keep the low clouds away, but not enough to prevent an earlier sea breeze. Max temps should cool 2 or 3 degrees each day. Despite this cooling max, max temps will remain at least 5 degrees over normal.

It should then remain dry through Wed the 11th. After that all long range mdls, AI, Deterministic and Ensemble all show an increased chc of rain from the 12th to the 19th.
