AgWeatherNet Weekly Weather Outlook for June 23 to June 29, 2018

Becoming Hot on Sunday; Cooler and Breezy Early Next Week

Nic Loyd, Meteorologist, 509-786-9357

A departing low pressure area will leave pleasant yet breezy conditions in its wake early on Saturday, although a building ridge of high pressure should cause warming temperatures by afternoon. The trend of dry weather and decreasing wind is expected to continue into much of Sunday, along with hot temperatures. However, an approaching system looks to bring a slight chance of showers to northwestern parts of the state beginning around Sunday night and persisting into Monday. Meanwhile, gusty winds are likely through at least Monday for many areas, as cooler air spreads across the region.

Tuesday is anticipated to be a rather delightful day, and then modest warming is predicted for mid week. The forecast for later in this outlook interval is not entirely clear, but model solutions have recently settled upon the idea of another weak system arriving near week’s end. In general, Washington can probably expect slightly cooler and unsettled conditions at that time, with eastern breezes and a slight chance of western showers.


Key Points:

  • Generally variable conditions.
  • Hot on Sunday, and cooler early next week.
  • Lower dew point temperatures expected by next Tuesday.
  • Mainly dry, but a slight chance of showers from Sunday night into early next week for western and perhaps northern Washington.
  • Breezy at times, especially for Monday and again later next week.
  • Periodic blowing dust and elevated fire danger, especially for Monday.
  • Despite the moderated temperatures, continued evapotranspiration (ET) and irrigation demand east of the Cascades due to sunshine and dry winds.
  • Warmer and benign around mid week, and then cooler and slightly unsettled at the end of the week.
