Winter has returned to the Bay Area with isolated to scattered rain showers and cooler temperatures on Friday. Isolated thunderstorms will also be possible Friday afternoon. Saturday will feature mostly dry conditions before another weather system brings more widespread rainfall Sunday into Monday. This system will be accompanied by a much colder air mass with lowering snow levels Sunday night into Monday, bring snow showers to the region’s ridges and peaks. While only lingering showers will be possible on Monday, a more potent weather system will arrive by midweek in the form of a weak to potentially moderate atmospheric river. This will increase the threat of nuisance type flooding in lower lying, poorly drained areas and could potentially trigger debris flows in recent burn areas. Stay tuned!
