Marine Weather and Tide Forecast for Garden Grove, CA

DISCUSSION
FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO COUNTIES...

Tonight through tomorrow...

Most of the low clouds have scattered out completely, with only a few areas of broken skies right along the immediate coast of southern Orange County and northern San Diego County. There could also be some patchy areas of fog again, although likely a little further inland due to ceilings rising a little more. As clouds thicken up due to an approaching trough, there could be some areas of drizzle possible, especially for the foothills and west-facing slopes. Winds will continue to increase and become gust for some of the deserts and mountains, with some more localized areas within Banning Pass and other locations which are more prone to strong winds to occasionally reach Wind Advisory criteria. These winds will begin to decouple and weaken going into the later hours overnight.

For tomorrow, there will be some areas of fog during the early morning hours for portions of the inland valleys, and likely a little further eastward. There could be some patchy drizzle possible, likely more for the inland areas and foothills, although not highest enough confidence to put this into the forecast grids.
As a shortwave trough begins to move in over the region, the tightening of the pressure gradient is going to allow for winds to increase for the lower elevations of the deserts, and approaching Wind Advisory criteria. There could also be some areas of blowing dust, especially within the first couple of hours after winds increase within the Coachella Valley. Due to this, and winds being strongest within this location, a Wind Advisory has been issued for the San Gorgonio Pass near Banning from 5 PM Friday through 3 AM Saturday.

This weekend through mid next week...

Winds will continue to diminish going into the early hours on Sunday as the trough continues to pull away from the region. There will be an overall area of troughing over the northwestern region, and possibly a weak upper level low transitioning over California during the early part of next week, which could help to reinforce some cooler temperatures and allow for a slight chance of precipitation.
Otherwise, generally it will remain cooler and more moist with a persistent onshore flow in place through the middle of next week.
