Puget Sound Forecast: Sunny skies. Highs in the mid to upper 70s along shorelines, and the low to mid 80's inland-generally 5 to 10 more miles inland.

Coast Forecast: Partly to mostly sunny. Highs in the mid to upper 60's. Northwest winds 10-20 mph.

Mountain Forecast: Partly to mostly sunny; clouds will be most likely to develop during the afternoon hours, especially south of Snoqualmie pass. Freezing level 13-14,000'. Pass highs in the mid to upper 70's. Pass winds west-northwest 5-15 mph.

Eastern Washington Forecast: Partly to mostly sunny and hot. Highs in the mid 90s to low 100s.


Expect temperatures to cool a few degrees today compared yesterday. Not much-just a bit. Thursday will be very similar.

Although the ridge of high pressure will keep the jet stream well north, it will also allow what we call the 'summer monsoon' to direct some thundershowers northward from the Rockies and Sierra Nevada into the Cascades and eastern Washington by late this week and into the weekend. Satellite images show the movement of these clouds north into eastern Oregon and Idaho. These thundershowers are likely to have very high bases, which means rain falling out of them will likely evaporate before reaching the ground. That would leave lightning, which of course could set off more fires.

But overall, west of the Cascades, longer range trends point to continued dry, unseasonably warm weather over Western Washington through the weekend and into early next week. It looks like super SeaFair weather!
