Relatively Calm Weekend Then Rain to Start Next Week

After localized gap winds and occasional rain on Friday, we will have a relatively calm weekend.

Saturday will start off chilly and foggy, with temperatures of 30-35 degrees and areas of fog around the region. (Graphic from NWS Seattle)


Due to the cold temperatures, there is also a chance of black ice and freezing fog on Saturday morning.

Where fog burns off, expect mostly sunny weather with highs in the 40s!

Another bout of easterly (from the east) gap winds in prone locations is expected Saturday through early Sunday morning. Expect the strongest winds in the outlined area (gusts 30-45 mph) and lesser winds (15-25 mph) in other foothill locations.


A system will bring occasional rain on Saturday night & Sunday morning. Expect only 0.05-0.2 inches of rain.

Sunday will be a day of scattered showers, with mostly cloudy conditions.

Starting Monday night, our next round of impactful rain will arrive. An atmospheric river (aka Pineapple Express) will bring heavy rain and higher snow levels to the Pacific Northwest. Due to this, a Hydrologic Outlook (below) has been issued by NWS Seattle.


The bottom line is that another round of rain that will elevate the landslide threat again and potentially bring flooding is on the way.

Details of rain amounts aren't yet certain, but a general idea is given by the Weather Underground forecast for Puyallup.


It looks like the heaviest rain (along with some possible gusty winds) will occur on Monday and Tuesday of next week. Temperatures will likely be mild (50s) all of next week.

Next week's forecast totals another 1-3 inches of rain in the lowlands, adding to the 2-5 inches of rain that has already fallen this month.
