A mild southwesterly air flow is expected to persist for most of the outlook period, as variable weather and above normal temperatures continue. This weekend will be a relatively quieter period, as lingering western rain on Saturday morning gives way to drier conditions later in the day and into Sunday. Rain should develop at the coast on Sunday night, before spreading into the western interior on Monday. The system will finally pass through the state on Tuesday, with a chance of rain for eastern areas as well. Otherwise, breezy conditions and cooler yet still mild temperatures are anticipated.

Another warmer storm is likely later in the week, although the timing and exact details are uncertain at this point. It appears that western areas, especially in the north, could see significant rain totals during the Wednesday into at least Thursday time frame. Meanwhile, a building ridge over the Rockies could keep southeastern areas of the state rather dry. The big question will be how much of the western rain makes it into eastern areas of Washington later next week. Although several impulses of subtropical moisture are likely to impact the western part of the state, their trajectory should be such that Washington stays mainly in the warm sectors of these disturbances.
