Morning Weather Forecast for Saturday, 9/12

FOX 13 Chief Meteorologist Brian Macmillan has your morning weather forecast for Saturday, Sept. 12.

If you have outdoor plans this weekend, you'll want to keep the rain gear handy. An area of low pressure moving inland will bring cooler temperatures and rain to Western Washington Saturday night into Sunday morning.

Saturday Night: Rain Arrives

Rain showers will become more widespread late Saturday as an upper-level low pressure system moves inland.

Expect periods of rain across Western Washington on Saturday night, with the potential for a few thunderstorms mixed in. Overnight lows will be in the mid 50s.

Sunday: Showers, Rain and a Few Rumbles

The unsettled weather continues into Sunday morning, with rain likely in the first half of the day. Thunderstorms will remain possible, especially over the Olympic Peninsula and southwest interior. Most of the Puget Sound area could see up to a half-inch of rain when all is said and done. Areas farther north, including around Bellingham, should see less rainfall.

Showers will taper off Sunday afternoon, but showers could linger in the mountains.

Tuesday and Beyond: Warming Up

Tuesday, sunny skies return. By Wednesday, an upper-level ridge will build over the Pacific Northwest. Most of next week looks fantastic, with sunnier skies and highs close to 80 degrees by the end of the week.
