SYNOPSIS
High temperatures the coast to the coastal slopes of the mountains will warm several degrees today with faster inland clearing of night and morning coastal low clouds today and Tuesday. Warming will expand into the deserts on Tuesday and continue on Wednesday as the coast and valleys begin to cool on Wednesday. Not much change in high temperatures for Thursday through Sunday with high temperatures a few to around 5 degrees above average. A more persistent coastal eddy will bring greater coverage of night and morning coastal low clouds for the middle of the week with low clouds spreading into the western valleys for early Wednesday and into the inland valleys for early Thursday.
DISCUSSION
FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO COUNTIES...
.SHORT TERM (Today through Wednesday)...
Northwest to north winds for the mountains and deserts will become north to northeast this morning, then diminish through the afternoon. High temperatures for the deserts will be a few degrees cooler today. High temperatures for the coast to the coastal slopes of the mountains will warm several degrees today, as much as 10 to 15 degrees for the Inland Empire. There will be warming for most areas on Tuesday with high temperatures as much as 5 to 10 degrees warmer for the mountains, deserts, and inland valleys. For Wednesday, the coast and valleys will begin to cool while high temperatures for the mountains and deserts warm another few to around 5 degrees.
While a weak coastal eddy will continue at times through Tuesday, mainly nights and early mornings, low clouds should clear faster for inland areas, especially on Tuesday. However, the local NAM- bounded WRF shows a more persistent coastal eddy developing Tuesday night and continuing into Thursday with more widespread coastal low clouds spreading into the western valleys for Tuesday night into Wednesday morning and into the inland valleys for the Wednesday night into Thursday morning as the marine layer deepens.
.LONG TERM (Thursday through Sunday)...
There will be slight day-to-day differences in high temperatures for Thursday through next weekend with high temperatures a few to around 5 degrees above average. High temperatures will range from around 70 near the coast to the 80s for the Inland Empire with the lower deserts around 100.
AVIATION
180930Z
Coast/Valleys
Low clouds with varying bases 2000-4000 feet MSL will scatter out from northeast to southwest this morning by 16Z. Low confidence in the return of low clouds this evening, but areas should return mainly vcnty KSAN after 03Z. Any cigs would be based around 1500 feet MSL and intermittent.
Mountains/Deserts...Offshore northerly winds will bring gusts 25-35 knots through and below mountain passes through 20Z. Pockets of LLWS and downdrafts in lee (south and west) of mountains.
MARINE
No hazardous marine conditions are expected through Friday.
BEACHES
Surf up to 5 feet this morning will gradually fade during the day.
Elevated surf could combine with high tides this morning to produce minor tidal overflow. See the Coastal Hazard Message for details.
