(tdy-Mon), 03/1228 PM.
A typical Santa Ana wind day across LA/Ventura coast and valleys with gusts between 25 and 50 mph and temperatures in the 70s and lower 80s. And per usual with Santa Anas winds will drop off later this afternoon and evening, then return again later tonight and Saturday. Tomorrow's winds will be gusty but generally 5-15 mph lighter than today as upper support weakens. Will hold off with any wind advisories for tomorrow as the decrease in winds may be enough to keep most areas out of advisories. At most it would be very low end advisories in fewer areas.
Main thing tomorrow is temperatures should jump up several degrees in all areas due to weakening cold air advection and high pressure aloft building over California. Expecting highs tomorrow to be 5-10 degrees warmer than today in all areas, with some warmer valleys reaching the lower 90s and coastal areas in the upper 70s and 80s.
A slow cooling trend will begin Sunday and continue into next week, though high pressure aloft will hang around and keep highs at least a few degrees above normal for most areas through Monday. May see some low clouds and fog returning to coastal areas by Monday as light onshore flow returns.
(Tue-Fri), 03/1225 PM.
After the slight cool down early in the week, temperatures are expected to level off Tue/Wed at 4-8 degrees above normal. Skies will be mostly clear, except light to moderate onshore flow will create areas of low clouds and fog near the coast.
Models continue to indicate at least a 60% chance of rain area- wide late Wednesday night or Thursday. A majority of the solutions are still favoring around a half inch, but there is still around 20% of solutions showing a inch or slightly more. There are also some much slower solutions that start the rain as late as Friday and linger into next weekend.
