The Cooling

4 PM Update...the Hoquiam-Seattle pressure difference is now 3.8 mb. A strong onshore push is thus guaranteed. Put up your wind chimes. It is coming. If anyone is planning on hitting the water...particularly in sail boats...please be prepared and careful. The winds will pick up later and get quite gusty.

We had a minor intrusion of cooler air at low levels last night into the interior, but this thin veneer is rapidly getting mixing out...so temperatures will surge now back into the 90s...sorry. The coast is much cooler (60s). There should be a modest onshore push of marine air tonight...watch the difference in pressure between Hoquiam and Seattle...when it gets above 3-3.5 mb you know it is coming. The thermal trough should jump into eastern Washington with the push and temps tomorrow should only get into the mid to upper 80s. Hard to believe that 80s seem cool.
