Weather Discussion:

Sea-Tac finally broke the 80-degree barrier yesterday, after nearly 9 months, hitting 83 degrees! Shelton was the hot spot officially at 87!

Sunshine will continue today but things will be changing. The offshore winds have shifted to onshore today as a weak weather system moves down the BC coast. Clouds will move into the coastal beaches later in the morning and there may be a few showers on the north coast this afternoon.  Clouds will increase over Puget sound late this afternoon and we could see a few showers around sunset as we develop a little bit of a convergence zone. a

The weather system will move through southern BC on Wednesday keeping western Washington cooler  with highs in the 60's, and a mix of clouds and sunshine. There will be a chance of showers but those should be primarily in the mountains.  The clouds and a chance of a couple of showers may linger into early on Thursday but building high pressure off the coast will gradually clear us out on Thursday back to sunshine.

Right now it looks like a large ridge of high pressure will settle in over us for the entire Memorial Day weekend for a few morning clouds otherwise mostly sunny skies and high in the 70's Looks pretty nice!
