AgWeatherNet Weekly Weather Outlook for September 10 to September 16, 2016

Becoming Breezy This Weekend; Warm Days and Cool Nights Next Week

Nic Loyd, Meteorologist, 509-786-9357

The upcoming outlook period that will eventually lead us into mid September is likely to feature a range of interesting weather features. Still, the general trend should be gradual warming for next week, and mainly dry conditions. A warm but increasingly gusty Saturday afternoon in the east should yield to breezy and briefly cooler conditions through early next week, as a pulse of dry air infiltrates Washington from the north on Sunday. Despite a slight chance of showers in northwestern parts of the state on Saturday night, the event is anticipated to be largely void of precipitation.

As a ridge of high pressure attempts to build in next week, overall warming is expected, although the nature of the warming will be quite variable. Initially, warmer days are likely, especially in the west, while dry and increasingly stable nights could become chilly at times once the wind subsides. In fact, some isolated frost is possible for eastern Washington on Tuesday and Wednesday mornings. Early to mid next week should be a good example of a time interval with large diurnal ranges where one is overheated in the afternoon sunshine, and then cold by the next morning. Eventually, hot temperatures may return at the end of the period, although given the time of year, mornings should remain rather comfortable.
