Winter officially begins today! High pressure will keep it dry with valley inversions in place. A more active weather pattern will develop later in the week, breaking up the inversions and bringing better air quality. Mainly valley rain and mountain snow is expected by Thursday. As colder air moves in, rain will change over to snow by Friday and become widespread across much of the area.
