Temperatures will be cooler on Wednesday night, but should remain just above freezing in most spots.  Areas near Maple Falls may see a light freeze, though.  Since it will only be a light freeze frost/ice concerns should mainly be for bridges and shaded/elevated roads.  Temperatures increase overnight as mid to high level clouds increase so precipitation should just be falling as rain when it returns late Wednesday night/early Thursday morning.  Rain continues most of the day Thursday before tapering off west to east during the mid to late afternoon hours.  

    Showers linger off and on through Thursday night and Friday before tapering off Friday evening.  Temperatures are expected to fall near or a bit below freezing in spots on Friday night before clouds increase and bring temperatures back above freezing by Saturday morning.  Steady light rain begins midday Saturday and continues through the day before breaking up into showers during the evening.  Snow levels should rise enough by midday that precipitation falls as all rain, but there is a bit of a concern that areas near Maple Falls mix with or go over to rain before rain breaks up Saturday evening.  Rain showers linger through Saturday night, and Sunday before tapering off Sunday night.  At this time, conditions look dry for the beginning of next week.

  • when ocean waves come on shore,

  • when dams or levees break.
