After the heat from Wednesday, Northcentral Washington can expect more comfortable weather today under deck of clouds with spotty showers through tonight. A flattened upper level ridge of high pressure will be over the region with a pair of pesky shortwaves slowly drifting through the flow. With a dry sub cloud layer, most of any precipitation will evaporate and keep the showers light and spotty with little in the way of measureable precipitation. The shower chances decrease early this evening although the chance of light showers persist overnight as the moisture band continues to lift northward and a second shortwave moves across the Cascades to northeast Washington on Friday.

Meanwhile drier air moves in across the Central Cascades and Columbia Basin by Friday afternoon into Friday night. Local westerly wind gusts are possible by Friday evening especially across the Columbia Basin. Under mostly cloudy skies with a slight chance for a sprinkle or two, high temperatures today should top out in the upper 80’s. Clearing for Friday with a light northwest breeze, highs tomorrow also in the upper 80’s.

Saturday through Monday and the holiday weekend look very nice as high pressure once again builds in the Eastern Pacific. Northcentral Washington can expect mostly sunny to sunny skies each day, light wind with afternoon high temperatures in the upper 80’s, overnight lows in the lower 60’s.

Some uncertainty in the weather forecast for Tuesday and Wednesday but for now expect mostly sunny skies with afternoon highs in the mid to upper 80’s.
