A series of Pacific weather systems promises periods of rain across Western Washington this weekend, with plenty of snow in the mountains.
Friday will bring scattered showers with some sun breaks at times in the wake of an earlier weather system. Then, a pair of systems is expected to move ashore, bringing rain at times on both Saturday and Sunday. Interior total rainfall amounts should range from a half-inch to just over an inch. Breezy conditions are anticipated as well on Saturday, with wind speeds up to 30 mph.
This is a cool weather pattern, and high temperatures will be about five degrees cooler than mid-March averages. Highs through the weekend are forecast to range from the mid-40s to lower 50s, with lows in the mid-30s to lower 40s.

We’ll also get snow – in the mountains
The cool, soggy weather pattern will also produce much-needed snow in the mountains. The current mountain snowpack is below average, with the North and Central Cascades at about 75-100% of normal. The water equivalent in the snowpack ranges from only 60-75% of average.
Mountain snow totals this weekend will likely pile up to one to two feet of fresh snow. Motorists heading into the Cascades for fun in the snow or crossing over into Eastern Washington need to be prepared for hazardous winter driving conditions, with snow coming down heavily at times. Carry chains (state law) and be ready to use them if required. Snow levels will be below the passes, including Snoqualmie and Stevens Pass, hovering between 1,500 and 2,500 feet.
The new snow will also elevate the threat of avalanches. Those heading into the backcountry for skiing or on snowmobiles need to use the buddy system, avoid avalanche-prone areas, and have personal emergency signal devices at hand. Be sure to check the latest avalanche conditions from the Northwest Avalanche Center.
Many have outdoor plans this weekend, so be prepared for soggy, cool weather conditions. Sunday, March 15, is the Ides of March, and the weather will likely feel like it.
