A weak weather wave along the Pacific Coast will move inland today as a warm front was draped across Southwest Washington. With the parent trough off the coast stretching and only making small progress north through the day, expect mainly increasing middle to high-level clouds today with afternoon high temperatures warming into the mid-60’s.

Then tonight into Wednesday, the frontal wave pushes inland and into Northcentral Washington. There is a 30% chance of light showers tonight with overnight lows in the lower 40’s. On Wednesday morning and afternoon modest shower chances will be found near the Cascades, the northcentral and the eastern third of Washington. Expect a 40% chance of showers during the day Wednesday with high temperatures in the lower 60’s. Later Wednesday evening into the overnight the front moves east and drier air starts to move in, shifting the primary threat of showers into the mountains. Thursday will provide a bit of a break from the wet weather with mostly cloudy skies and cooler temperatures with highs in the upper 50’s.

However, by Thursday night, a very large area of low- pressure will begin to eject waves of moisture into the Pacific Northwest bringing a 50% chance of rain.
