AgWeatherNet Weekly Weather Outlook for May 27 to June 2, 2017

Very Warm and Mainly Dry Through Tuesday; Possibly Cooler Thereafter

Nic Loyd, Meteorologist, 509-786-9357

Strong warming and mainly dry conditions will be the main weather highlights through early next week, as another ridge of high pressure assumes residence over Washington. A lack of robust offshore air flow suggests that the coast should never become excessively warm, although most of the state is expected to observe several days of hot weather. A degree of marine influence may impact western areas early next week, though any temperature moderation is likely to hold off until at least mid week east of the Cascades. As is often the case, the low temperature trend is forecast to lag that of high temperatures. Due to southerly air flow behind the exiting ridge, eastern mornings are not anticipated to experience any notable cooling until late in the period. The ridge could weaken and depart to the east later in the outlook interval, but the details on how and when the transition occurs remain uncertain. Increasingly unsettled conditions are possible later next week, with the potential for breezes and scattered showers or thunderstorms. Thus, it appears that much of the state would be well advised to brace for an extended early season heat wave. Still, relative to the last few years, this upcoming hot spell may seem rather garden variety, or at least tolerable.
