AgWeatherNet Weekly Weather Outlook for August 26 to September 1, 2017

Strong Warming This Weekend; Heat Wave Early Next Week

Nic Loyd, Meteorologist, 509-786-9357

The calendar suggests that September is just around the corner, but the weather must have missed that memo. Significant warming is expected this weekend due to a building ridge of high pressure. By early next week, some locations in central Washington should be above 100 degrees during the day, while most other areas will be well into the 90s. There is likely to be a degree of western cooling by mid next week, although the heat may persist in the east. Any relief that eventually infiltrates eastern Washington is anticipated to be brief, as the ridge looks to rebound in strength by Friday.

Given the lack of marine influence, smoke and haze could increasingly become an issue over time east of the Cascades. As we have seen recently, areas of thicker smoke can experience minimally suppressed daytime temperatures, although very warm and rather unpleasant weather is still the expected outcome. Overall, hot, dry, and fairly calm conditions could potentially continue well into September, as summer shows no sign of yielding ground just yet.
