Happy Monday!  We're off to a calm start with temps in the 40s and 50s so far. It's already really nice out and will only get warmer...in fact hotter this afternoon.  Sunday marked our 3rd consecutive day in the 70s in Seattle, thanks to a ridge of high pressure over western Washington.  The heat will peak today with highs in the low to mid 80s around Puget Sound, 70s to the north and along the coast. 

Tuesday will still be very warm around Puget Sound with highs in the 70s, but the coast will be much cooler as onshore flow strengthens near the surface, and an upper level trough starts to dig into western Washington.

A marine push will bring more clouds and occasional spotty showers Tuesday night through Thursday with highs in the 60s.  The trough should weaken by Friday with highs climbing to around 70.

Another ridge of high pressure is expected to build in for the holiday weekend bringing more sunshine and highs well into the 70s.
