AgWeatherNet Weekly Weather Outlook for May 6 to May 12, 2017

Cooler This Weekend; Warmer and Drier Early Next Week

Nic Loyd, Meteorologist, 509-786-9357

In the aftermath of the recent volatile conditions, the weather should begin to stabilize this weekend and especially early next week. Although the pattern will remain changeable, the active regime and rapid temperature swings of the past few days are likely to subside somewhat in the short term. A slight chance of showers (except in central Washington) and widespread cooler and breezy conditions are expected on Saturday, before drier and calmer weather develops on Sunday. Early next week looks to be warmer and rather benign, as temperatures once again rise to above normal. However, the building high pressure is not forecast to become very strong. As a low pressure area slowly approaches the region from the west later in the period, unstable southerly flow may start to transport clouds and moisture into the state.

Though the details of when and how the low ultimately impacts Washington remain uncertain at this point, pattern recognition suggests that showers, thunderstorms, and breezes are again possible at that time. If the low stalls off of the coast, shower chances and cool air intrusion may be limited in their eastward progression across the Northwest. If, however, the low is more aggressive in moving toward Washington, cooler air could even reach eastern locations by the end of the week. In any case, increasingly unsettled conditions are anticipated later in the period.
