Looks like we are heading for an extended period of cool and wet weather - this will be great for the garden.
From Cliff Mass:
Major Cooling Ahead
We have all gotten used to the warm, sunny weather, which followed the warmest April on record for many Northwest cities.
But it is all going to end this weekend, with cool, showery weather settling in for an extended period.
Real meteorologists prefer to look at the output of ensemble forecast systems that present the results of many predictions. Here is the graphic from the North American Ensemble Forecasting System. Warming through Friday...and then bang... an extended cool off, with increased chances of precipitation and clouds (the yellow boxes show the range of the middle 50% of the ensembles, the "whiskers" indicating the range of the predictions.
A thorough analysis of what we have to look forward to. The off-shore high pressure ridge that has given us all of our nice warm weather is going to (as Cliff said) Ridge Heaven.
