Active weather will continue for the next seven days, as storm systems periodically impact Washington. The weekend will feature continued unsettled weather with cool daytime conditions. Showers are likely on Saturday in western Washington, with slightly drier conditions likely by Sunday. Central Washington will be mostly dry over the weekend, with only a slight chance of showers and breezy conditions. The best chance for a relatively calm period would be the Sunday-Monday timeframe. The most likely time for subfreezing temperatures would be Sunday and Monday morning, especially if skies are clear and winds are calm.

The weather will become wetter next week, as a strong jet stream once again takes aim on the region. A mild, southwesterly air flow will steer a juicy storm with sub-tropical connections toward Washington around Tuesday of next week. The system will bring rain to western Washington, along with a chance of rain at times to areas east of the Cascades. Some temperature fluctuation is likely, as difficult-to-time storms pass through the region. Although the details regarding the strength and track of next week’s storms remain uncertain, it generally appears that cool temperatures early in the week will give way to milder weather around mid next week. Periods of rain and snow will continue in the mountains next week.
