Discussion:

The scattered rain showers anticipated for this Wednesday, as discussed in last Fridays outlook, look to move in a bit earlier and not be as widespread as anticipated. A few light showers are expected to start moving in from the west Tuesday evening in western Washington as part of a decaying frontal boundary associated with a surface cyclone near the eastern Aleutian Islands. Showers look to be relegated mostly to the northern half of the region with greater shower activity through the Cascades and Olympics. However, a few isolated light rain showers will also be possible through coastal areas of western Washington as well as upland and mountain regions of northern Washington east of the Cascades. These rain showers will be generally short lived with low elevation areas of western Washington trending dry through Tuesday night. A few light rain showers are likely to linger over parts of the Cascades and Olympics through mid week however. Conditions look to remain dry through the remainder of the week with temperatures remaining seasonable as well.

Weather looks to again turn much more active beginning Friday night and lasting through the weekend. There is a sense of déjà vu as the cause of this weekends rain appears to be from two upper lows. One currently positioned off the southern California coast which looks to move northeast through the Great Basin and into Idaho and western Montana. The other associated with the surface cyclone currently situated near the eastern Aleutians and looks to slowly move its way southeast. Washington state will likely be again caught in the middle of the passing disturbances, creating unsettled weather. Mountain and upland areas are expected to see scattered as well as extended periods of rainfall through the weekend. The central Basin and south Central Washington will see a lesser chance for rain with only some scattered and isolated showers anticipated. Showers look to move into the state from the west/southwest beginning as early as Friday night.

The upper low moving in from the northwest is expected to bring much cooler air along with it. Overnight temperatures Saturday night and Sunday night look to become a bit chilly through areas that typically run colder than their surroundings. Mitigation will likely not be needed but the situation bears watching and will be touched upon in Friday's outlook. At this time, please be alert that below average temperatures are anticipated for Saturday and Sunday nights.
