SYNOPSIS

High temperatures will warm a few degrees for today and Saturday and cool a few degrees for Sunday and Monday, but remain at least a few degrees below average for the valleys. High pressure to the east will bring a warming trend beginning on Tuesday with high temperatures warming to around average for next Wednesday and a few degrees above average for next Thursday. The marine layer will become shallower over the weekend with night and morning coastal low clouds not spreading as far into the valleys.

SHORT TERM (Today through Sunday)

Low pressure over California will weaken and move inland today with high pressure aloft moving inland across California on Saturday. A low pressure system will develop off the California coast on Sunday and move inland into California on Monday.

High temperatures will warm a few degrees today and a few more degrees on Saturday with high temperatures on Saturday still as much as 5 degrees below average for the valleys. High temperatures on Saturday will range from the 70s near the coast to the mid 80s to lower 90s for the Inland Empire with the lower deserts around 100. High temperatures on Sunday will be a degree or two cooler for the coast and valleys.

The marine layer is around 3500 to 4000 feet, lower than the 4500 to 5000 feet for early Thursday. Coastal low clouds will extend inland across much of the valleys into this morning, then not as far into the valleys during the weekend as the marine layer becomes shallower.

LONG TERM (Monday through Thursday)

High temperatures on Monday will cool another few to around 5 degrees with the greatest cooling for the inland valleys onto the the coastal slopes of the mountains. High temperatures on Monday will be as much as 5 to 10 degrees below average for the mountains and valleys with high temperatures ranging from the lower to mid 70s near the coast to the upper 70s to mid 80s for the Inland Empire with the lower deserts in the upper 90s.

High pressure over Texas and northern Mexico is expected to bring a warming trend beginning on Tuesday and continuing for much of the rest of next week, though with increasing spread in just how much warming may occur. NBM has the greater warming for Tuesday and Wednesday with lesser additional warming for Thursday and Friday.

High temperatures would warm to within a few degrees above and below average on Wednesday and to a few degrees above average on Thursday. High temperatures on Thursday would range from the mid to upper 70s near the coast to the upper 80s to mid 90s for the Inland Empire with 100 to 104 for the lower deserts. Dry weather is expected to continue through much of next week.
