Some slight cooling this week

Posted at 4:51 PM, Aug 05, 2019

A mix of high clouds and some lower clouds greeted the Central Coast this morning. Similar conditions are expected into Tuesday with some minor changes.

The upper level circulation over the 4 corners region looks to weaken and drift east. This will place the Central Coast in a SW flow aloft. This generally produces near average conditions for the area. For the next 3 days inland highs look near average in the lower to mid 90s. Beaches in the 60s and low 70s and coastal valleys in the low to mid 70s. Southcoast highs near 80 and Santa Ynez valley temps in the mid80s to about 90.

There will be a low marine cloud deck in the night and morning hours and that deck should deepen (grow taller) which will allow it to get further into the coastal valleys as the week progresses. This along with the weakening high will produce the subtle cooling trend.

I think we still see some high clouds from upper level moisture, but that shouldn't influence temperatures much.

We should see some stronger winds in the SB county mountains, passes and canyons each night as sundowner conditions look likely. Today the winds should stay below advisory levels but we'll have to watch that each day.

The longer extended forecast is interesting. There is already an upper low spinning off the Pac NW. Mid to late week it moves east and this will finally cause a deeper trough over the Central Coast and California in general. This will produce cooler temps, below average inland for the coming weekend.

However after that another ridge develops and inland temps look to crawl back into the mid to upper 90s (possible triple digits) early next week. Coastal highs will also come back up but just to about 5 degrees above average.
