Although clouds and isolated showers may linger in mountainous and northern areas on Saturday, conditions will generally be calmer and drier across the region, as the storm responsible for the recent inclement weather slowly moves off to the east. Sunday will be a mainly sunny and warmer day across the region. High temperatures this weekend in the west will be in the 70s, with lows in the upper 40s to 50s. In central areas, highs will be in the mid 70s to 80s, with low temperatures in the 50s. In the east, highs will be in the upper 60s to 70s, with lows in the upper 40s to 50s.

Another strong ridge is expected to dominate the Northwest next week, as summer weather returns to Washington. Hot and dry conditions are likely all week long, with temperatures warming through at least Wednesday. Eastern areas around Pullman and Spokane should experience highs in the 80s to low 90s, with lows in the 50s. Central areas will climb into the upper 80s to mid 90s during the day, with low temperatures in the 50s to mid 60s. Interior western areas will see highs in the upper 70s to 80s, and lows in the 50s. Near average temperatures are forecast during the week two period, as there are indications that cooler air may finally arrive in mid September.
