SYNOPSIS

28/745 PM.

Night through morning low clouds will prevail through most of this week, with temperatures well below normal through at least Thursday. Modest warming is likely to follow. Drizzle will be possible each night, especially near the foothills. Gusty winds will continue over the interior mountains and deserts, as well as southwest Santa Barbara County through at least early next week.

LONG TERM (THU-SUN)

28/209 PM.

Good consensus among ensemble and deterministic guidance of high pressure building over the region Friday and Saturday. This will result in a warming trend into July 4th weekend as 500mb heights continue to rise and gradients trend offshore. Temperatures will likely warm even more into next week - however, there is quite the range in solutions. Stay tuned for updates.
