IS A WARM CUP
Southern California Overview:
- Weakening high pressure aloft, and an incoming Pacific trough, will flip our winds back onshore, beginning the return of marine air tonight, with possible coastal fog. Strengthening sea breezes will spread cooling and humidity well inland on Wednesday. By Thursday, strong westerly winds will drive further cooling across the mountains and into the deserts. Winds will flip again on Friday, becoming northerly and gusty below the passes and canyons. This will return Southern California to Santa Ana conditions again this weekend, complete with locally gusty northeast winds, low humidity, and above average daytime temperatures west of the mountains.
- Excessive rainfall and flooding potential continues across the Pacific Northwest. Moderate upslope snow forecast across the central and southern Appalachians today. Well above average and potentially record-breaking warmth forecast across the central United States over the next few days.
