Seattle weather: Showers with a chance of graupel, but sun on the way

Another day of drippy clouds is ahead before the sun comes out of hiding.

Scattered showers will stream eastward over the region Tuesday morning, slowly shifting southward by the afternoon, according to the National Weather Service.

As showers shift south, high pressure is expected to build in the atmosphere above, creating conditions for potential lightning and graupel with the development of stronger showers in the afternoon, the weather service said.

Graupel, also known as snow pellets or soft hail, forms when water droplets freeze onto a snow crystal, according to the weather service.

The clouds are expected to have wrung out all their moisture by the evening before clearing overnight.

As we roll into May, overnight temperatures in some locations across Western Washington will bottom out near freezing.

Once the sun is up Wednesday, though, dry conditions will prevail, as highs warm to the lower 60s, the weather service said.

A chance of showers returns late Wednesday into Thursday.
