A cool down with a return of night through morning low clouds and fog will start Monday night and continue through late in the week. Drizzle or light rain is possible Wednesday into Thursday morning, amounts would be very small just a couple hundredths of an inch.
Monday interior areas warmed up while coastal areas started to cool down things to a weak onshore flow.
Monday night a wind advisory is in place for the Santa Barbara South Coast and mountains until 3AM Tuesday. These winds will also hold off the low cloud push tonight across southern Santa Barbara County and Ventura County but clouds should start to fill in early Tuesday and certainly by Tuesday evening.
The rest of the week will be much cooler as a couple of low pressure systems drop out of the north and move through the state. Onshore flow will continue to increase and the marine layer will become much more widespread and include the coastal slopes by Wednesday and Thursday.
The first upper low Wednesday will mostly stay north and east of the area but significant cooling aloft will push the marine layer depth above 3000'. This will bring us a chance of drizzle across the area Wednesday and Thursday and bring lows into the 60s.
Strong onshore flow to continue Friday and into the weekend, though the upper lows will be replaced by a weak ridge Friday into early Saturday that will help warm temps a few degrees and reduce the marine layer depth and speed up clearing. There is a chance of rain next Sunday into Monday. We will update you on the likelihood of this storm as we get closer. For now amounts look very small if any. Stay tuned.
