IS A WARM CUP
September 22, 2020, 12:42 PM PDT
Southern California Overview:
- Mild weather will prevail today with the upper level trough of low pressure moving by to the north. Locally gusty westerly winds will occur in the mountains and deserts this afternoon and evening. High pressure aloft will bring warmer weather Wednesday and Thursday with patchy night and morning coastal low clouds and locally dense fog. Cooler weather will return Friday and Saturday as another trough moves by to the north, but then stronger high pressure aloft will build early next week and bring hot weather to many locations, and gusty easterly winds will occur, especially Sunday.
- Tropical Storm Beta is forecast to weaken and gradually lose tropical characteristics while spreading flooding rains further inland across the lower Mississippi Valley. Large swells generated by Hurricane Teddy could cause dangerous surf and rip current along the U.S. East Coast. Another frosty morning in parts of the Northeast; warm in the West and the northern Plains as rain moves into the Pacific Northwest.
