Rain & Mountain Snow Return on Monday

FastCast—Monday, Nov. 22 to Friday, Nov. 26:

After a brief hiatus from the rain (and a great weekend), the rain returns on Monday. First off, a cold night is expected, with lows in the low 30s and frost possible. Fog, potential freezing fog, and black ice is possible, especially in valleys and outlying areas. Additionally, stagnant air is possible through Monday, with degraded air quality, due to a high pressure ridge and relatively little wind. Clouds move in through the day, with rain beginning by late afternoon. Spotty showers are expected on Tuesday and Wednesday. Expect 0.2-0.5” in the interior lowlands through Wednesday. Mountain snow is expected from Monday night to Wednesday. Up to 8 inches is expected through Wednesday before the snow level rises above the passes. The next system moves in on Thanksgiving, with up to 1 inch of rain on Thanksgiving. Showers continue on Friday. Expect highs in the upper 40s to low 50s, and lows in the mid 30s to low 40s, except in the low 30s Monday morning. Stay tuned for more information about the upcoming weather systems!

What a nice weekend! It was actually dry, a rare feat this month! I took the photo below at Snoqualmie Pass on Saturday.


It was nice to enjoy the dry weather while it lasted, as the next rainy period is in the forecast. 

Below is the UW rain forecast through 4 PM Wednesday.


Expect 0.2-0.5 inches of rain in the Interior Lowlands, with more in the foothills and on the coast. Up to 0.5 inches of rain is possible in BC’s Lower Mainland, where areas are still underwater.

The other impact will be mountain snow, mainly from Monday evening to Tuesday evening. Below is the UW snow forecast through 4 PM Friday.


Expect up to 8 inches at the Passes, before the snow level rises by Wednesday.

More rain is expected, especially on and after Thanksgiving. Additionally, temperatures will rise, with highs in the mid 50s and lows in the mid 40s. Below is the Weather Underground forecast for Federal Way.
