Synopsis

21/227 AM.

Widespread rain will develop later today and continue into Thursday with a chance of thunderstorms. A weak Santa Ana will develop in the storm's wake by the weekend for dry and warmer conditions.

Long Term (sat-tue)

21/227 AM.

Weak ridging and weak (1 to 3 mb) offshore flow from both the east and north will be in place for the entire xtnd period. The best upper level support will be on Saturday when there will be 30 to 40 mph gusts csts/vlys and as high as 50 mph in the mtns. The winds will be weaker starting Sunday.

High pressure and offshore flow should keep the skies clear.

There will be decent warming on Saturday (4 to 6 degrees) and then 1 or 2 degrees of extra warming Sun and Mon. Tuesday will cool some as the ridge and offshore flow weaken substantially. Cst/Vly temps will be a little above normal while the interior will be several degrees blo normal.

A quick look at the AI long range models shows dry conditions through the end of the month.
