27 Oct 2018, 4:10 pm

Heads up, Northwest! You’ll be turning much wetter and consistently cloudier as the weekend rolls on. Hopefully you have taken advantage of your time to enjoy the dry conditions, because that window to do so is quickly closing!

The clouds were already streaming into Oregon on Saturday afternoon, the visual precursor to the next weather event.

The weather set-up on Saturday afternoon featured an approaching upper-level low, pictured by the big ‘L’ above. Note the fetch, or the arrows crossing the ocean and carrying the moisture, that was coming in all the way from the central Pacific! That means it’ll be a steady stream of showers ahead for the Pacific Northwest.

On and off rain showers will greet us out the door on Sunday morning, as well as Sunday evening. Fortunately, it *does not* look like this rain Sunday will prompt widespread flooding. Instead, some bigger puddles and nuisance, very minor flooding will be likely.

Sunday will be just the beginning! Through Tuesday, even more precipitation will be moving in! Still, it looks light enough not to produce widespread flooding, but rather slower travel. One good thing is that it could drop nice snow at the highest of elevations!

This system will eventually bring rain and snow to parts of the central United States in time for Halloween! We will continue to follow every piece of it as it moves east and we hope you stay with us here at WeatherNation.
