SYNOPSIS

06/1224 AM.

A moderate Santa Ana wind event will start today and will continue through Sunday. Temperatures will warm each day through Sunday when widespread highs in the 80s are expected. No rain is expected for the upcoming week.

LONG TERM (MON-THU)

06/248 AM.

The offshore push will only be half as strong as it was on Sunday. The upper flow, while still from the NE, will also be much weaker. There will be some morning canyon winds but they will not be advisory levels. The weaker offshore flow will allow for an earlier and stronger sea breeze and this along with less compressional heat will create a 5 to 10 degree cooling trend across the csts and vlys. Further inland there may be a few degrees of warming as the hgts rise a few decameters.

The offshore flow will turn onshore on Tuesday. This could create some coastal low clouds in the morning, but feel like the low atmosphere will be too dry for stratus formation. There will be a noticeable 3 to 6 degrees of cooling across the board with max temps ending up in the 70s across the csts/vlys, which is still 3 to 6 degrees above normal.

Offshore flow from the north will develop Wednesday morning and the onshore push from the west will weaken. At the same time a ridge will push in from SW and hgts will rise to 586 dam. 3 to 6 degrees of warming will push most vly highs into the lower 80s.

The ridge intensifies next Thursday and there should be weak offshore flow. This will bring 4 to 6 degrees of warming to the csts and vlys pushing vly temps into the mid and upper 80s making it the warmest day of the next 7.
