November 8, 2023 - National Weather Service Storm Prediction Center Officials report as a mid-level trough moves east across the Southwest, surface high pressure is arriving in its wake. This surface high is over Oregon this morning and will settle into the Great Basin by this afternoon/evening.

This will set up offshore Santa Ana winds across southern California during the day today with some assistance from surface heating and deeper mixing bringing stronger winds to the surface. Therefore, as the boundary layer cools, expect some weakening of winds.

However, as high pressure reintensifies across the Great Basin amid cooling overnight temperatures, expect the gradient to intensify again Thursday morning with strong offshore flow developing, particularly in Ventura county.

Some Elevated to locally critical conditions may be possible across parts of the Southwest today. However, these conditions appear somewhat transient and may not last long enough to warrant an Elevated delineation.
