DISCUSSION: 

Get ready for what's shaping up to be a pretty wet week around here.

Let's start with the first storm, which focuses the bulk of it's widespread steady rain today.  We could pick up as much as .50" of rain by the time this first system winds down Sunday night (more along the coast). The rain will stay fairly steady through the day on Sunday, turning to scattered showers by this evening.  Snow levels with this first system start at 3,000 ft then bump up to 5,000 ft.  What does fall above those elevations is enough for a Winter Storm Warning in the Northern Cascades of Whatcom and Skagit counties until 4pm today. Locations above 5,000 ft will see 12 - 18 inches from this first storm. With the higher snow level, a Flood Watch is in effect for Mason County due to the Skokomish River rising through Wednesday morning. 

Winds will also be an issue today. Most locations will see southeast winds around 15-30 mph with gusts up to 35 mph. However, Western Whatcom County, San Juan County, and the Admiralty inlet area will be under a Wind Advisory until noon today. Winds there could reach 20-35 mph with gusts up to 45-50 mph.

The first half on Monday brings a bit of a break in the action, but it won't last long.  The second, wetter system arrives Monday afternoon and brings heavier rain, particularly Monday night and the first half of Tuesday.  Totals from this one will be closer to an inch of rain across many locations by the time things begin to quiet down late Tuesday.  Once again, snow level looks to stay fairly high with this storm as well, staying above 5,000 ft for much of the time.

By Wednesday, things will have quieted down for a bit of a break in the action before the next storm arrives late Thursday.  Might see another break later Friday into Saturday.
