SYNOPSIS

19/543 PM.

It will be cool and breezy this evening, followed by a very chilly Friday before a slow warming trend begins for the weekend. Chances for rain next week are looking less and less as high pressure builds over the area with much warmer temperatures.

LONG TERM (MON-THU)

19/212 PM.

The weekend warming trend is expected to continue through Monday or Tuesday as models continue to shift back towards a high pressure ridge along the West coast and light offshore flow returns. By Monday, highs will be well into the 70s away from the immediate coast with a 20% chance of 80 in the warmest valleys.

Chances for rain for the middle of next week have been decreasing with each model run. Officially there is still a 20-40% chance of rain but based on the trends the last couple days would expect the chances to drop below 15% in the next day or two. The ridge does get knocked down a little and offshore flow will likely flip to onshore Wed/Thu leading to a slight cooling trend for a day or two, but highs will likely remain above normal into next weekend, with a possibility of highs rebounding back up close to 80.
