A changeable and unsettled weather pattern is likely in the coming week, as several storms impact Washington during the next seven days. Rain will develop in the west on Saturday, as storm number one approaches the state. The southerly flow in advance of the low pressure system should cause warming temperatures this weekend. Initially, the snow level is expected to rise well above pass levels, as rain falls on the new mountain snowpack. However, cooler air is anticipated to infiltrate the region on Sunday and Monday, causing the precipitation to transition to snow showers in the mid elevations. The cooling should influence western and eastern Washington, especially during the day, before eventually impacting central Washington.

A colder Tuesday morning is likely to give way to a drier and calmer day, before another front moves toward Washington on Wednesday. Storm number two could be accompanied by a stronger jet stream as well. Temperatures may warm beginning around the middle of next week, before cooling again takes hold at the end of the period. The timing of this system is uncertain, but at least eastern Washington should start Wednesday on a dry note. Overall, variable and slightly above normal temperatures are expected, while precipitation periodically impacts portions of the state. Although the precipitation will change back and forth between rain and snow in the mountains, we can be thankful for several potential periods of at least light snow accumulations. The first should occur late this weekend into early Monday, with the second round coming later next week. There is still a long way to go in terms of building a mountain snowpack, but at least this is a start. Something is much better than nothing.
