AgWeatherNet Weekly Weather Outlook for June 2 to June 8, 2018

Warmer This Weekend; From Cooler to Warmer Next Week

Nic Loyd, Meteorologist, 509-786-9357

As a flat ridge of high pressure builds across the region, a warmer, drier, and calmer Saturday is expected across Washington. However, an approaching weather system will bring changes beginning on Sunday. Increasing southerly air flow should cause warming in eastern Washington relative to Saturday, while marine air flooding into western parts of the state is likely to usher in cooling temperatures. Central Washington may be warmer on Sunday as well, although perhaps only slightly warmer near the Cascades.

As denser ocean air filters through the Cascade gaps on Sunday, increased winds are anticipated for especially south central Washington. Clouds are also forecast to increase in advance of the incoming disturbance, as scattered showers return to western areas. In fact, showers and thunderstorms are possible on Sunday night in far eastern Washington, and especially over higher terrain. Models indicate the presence of some instability and moisture as the lifting mechanisms (the storm and associated sharp cold front) approach that region, but stronger thunderstorms are always a difficult proposition around here since precisely the right combination of borderline factors is required for their formation.

In any event, Monday looks to be notably cooler and still breezy in the east, with a few lingering showers in the west. The slightly unsettled and cooler regime is predicted to slowly transition to a warmer, drier, and calmer pattern later in the period.

  • Warmer and pleasant on Saturday.
  • A chance of showers on Sunday and perhaps Monday in the west.
