Seattle weather: Temperatures to be few degrees warmer on Tuesday

Temperatures Tuesday will be a few degrees warmer than Monday's as a weak ridge of high pressure builds slightly to the east. Highs will stay below seasonal average with temperatures only reaching the low 70s and mostly cloudy skies.

Western Washington will see its first significant rain in weeks as a system moves through the region Tuesday into Wednesday.

Most of Tuesday in the Puget Sound area will feature a mix of clouds and sunshine, with high temperatures in the mid-70s. Light showers are possible along the Washington Coast and into the Olympic Peninsula, especially around the late afternoon hours.

Will it rain in Seattle tonight?

What's next:

Later tonight, a frontal system will push through Western Washington, bringing widespread rain showers. The heaviest rain in the Puget Sound area will arrive during the Wednesday morning commute. It hasn’t rained in a while, and this could create slick conditions on the roadways as oil and dirt rise to the surface. Exercise extra caution when heading out on Wednesday morning.

Wednesday afternoon, lingering post-frontal showers could develop into thunderstorms. The best chances for thunderstorm development are east of Puget Sound and north of Seattle. Light showers will linger into Thursday morning.

Big picture view:

A ridge of high pressure will develop over the Pacific Northwest Friday through the weekend. Temperatures will climb back into the 80s by Sunday.
