Seattle weather: Cool temperatures, lowland rain and mountain snow ahead

The upcoming week will bring cool temperatures, lowland rain showers and more mountain snow.

Steady morning rain will transition to on and off showers by midday Sunday. Temperatures will remain 5 to 7 degrees below average, in the upper 40s.

Snow will continue in the mountains for the first half of Sunday. As of 8:00 AM on Sunday, the passes accumulated 9 to 12 inches of fresh snow in 24 hours. A few more inches are possible before showers settle down later Sunday. Snow levels will remain below 4,000 feet for most of this week, which means more mountain snow is on the way.

What's next:

On-and-off showers will continue on Monday, though there will be a lot more dry time. The exception would be in areas of the Puget Sound Convergence Zone, where steady rain could linger.

We will get a break from the rain on Tuesday and the first half of Wednesday. The next round of rain, breezy wind, and mountain snow picks up Wednesday evening and will continue through the weekend.
