A warm front approaches overnight. Temperatures won't be falling much, with lows in the lower 40's. Expect increasing rain overnight, and Sunday is looking fairly wet, with scattered showers throughout. It may be a bit breezy early in the morning as the cold front passes.
Showers linger into Monday morning, decreasing somewhat in the afternoon. We should be (briefly) in between system to start the week before a stronger system arrives Tuesday.
Tuesday will feature a frontal system passing, with rain and some wind. The wind strength is still in question, but certainly at least a breezy day is expected. We will also deal with moderate to heavy rain, and heavy mountain snow falling at the passes.
We dry out fairly quickly Wednesday. It looks like another dry spell ahead, with a condensed version of what we just dealt with appearing likely (frosty mornings, sunny afternoons). This pattern looks to persist at least until Christmas Eve before more rain returns.
