SYNOPSIS

29/850 PM.

Low clouds will linger each night/morning along the coast and in coastal valleys with the potential for some very light drizzle. Falling heights will keep temperatures well below normal through the middle of the week. Temperatures will begin to warm by Thursday, with many valley locations warming into the 90s again by early next week.

LONG TERM (FRI-MON)

29/1209 PM.

Temperatures will continue warming by another several degrees on on Friday and warm to within a few degrees on either side of normal on Saturday. Ensembles indicate a pattern change come next weekend, although confidence in the temperature and wind forecast next week is moderate. Ensembles differ on the upper-level details, specifically the strength of the ridge. While Saturday, July 4th won't be the warmest day of the extended period, some locations could warm into the high 90s. The National Blend indicates over a 90% chance of 90 plus degrees across the Antelope Valley on the 4th while 50% to 60% chance across the San Luis Obispo Valley. The likelihood of reaching 85 degrees is much more widespread. Some models feature another PacNW low early next week while others maintain some magnitude of high pressure or a zonal regime heading into the middle of next week. Temperatures look to return to normal or slightly above with upper 80s to low 90s in the forecast again by early next week. Additionally, offshore sundowner winds could develop early next week along the Santa Barbara coast.
