Southern California Overview:
- High pressure will continue above average high temperatures for inland areas through Tuesday while weak onshore flow begins to spread cooling into coastal areas with a return and slow deepening of a shallow marine layer. A low pressure system from the southwest will move inland through southern California on Tuesday night and Wednesday with Wednesday high temperatures as much as 12 to 18 degrees cooler for the mountains and inland valleys and as much as 5 to 10 degrees below average for the mountains and valleys. High pressure will bring warming for Thursday and Friday with Friday high temperatures around 5 degrees above average for inland areas. A low pressure system moving inland to the north will bring cooling for next weekend.
- Low pressure system to bring locally heavy rain and gusty winds for the Northeast today. Windy, colder, and unsettled weather to spread across the northern tier states for the next couple of days. Unseasonable October warmth cross the southern Plains to start the week with highs climbing well into the 80s and 90s.
