AgWeatherNet Weekly Weather Outlook for August 12 to August 18, 2017

A Welcome Pattern Change on the Horizon

Nic Loyd, Meteorologist, 509-786-9357

If you can hold on for one more hazy day of excessive heat and smoke, the opportunity to take a deep breath should finally arrive on Sunday. The winds of change will thankfully allow for some ventilation of this stifling air mass, as we all breathe a collective sigh of relief. Initially on Saturday, however, the heat and smoke are still expected to linger, albeit to a lesser degree than in recent days. A slight chance of thunderstorms this weekend and breezy conditions on Sunday should keep the fire danger in the high range in the coming days. Also, blowing dust may become an issue east of the Cascades due to parched conditions and increasing winds.

Despite the potential weather concerns, the net effect of this pattern change should still be positive, as cooler and fresher air finally returns to the region. There is also a decent chance of rainfall in western areas on Saturday night and Sunday morning. After a pleasant start to next week, warming temperatures and even more dry weather is anticipated later in the period. Overall, summer is far from over and we are probably not out of the woods yet in terms of heat and smoke. Still, the next seven days will certainly represent a marked improvement over the past seven days.
