More Rain, Mountain Snow, and Breezy Conditions Ahead

FastCast—Friday, Nov. 5 to Monday, Nov. 8:

It has been a wet start to November! As you may expect, that will continue. There is a chance of rain on each of the next 10 days, with 2-4 inches expected over the next 7 to 10 days. Expect a break in the rain overnight Thursday, with rain beginning early Friday morning, tapering by early afternoon. Totals of 0.1-0.3 inches are expected. Rain begins again very early Saturday, continuing through Monday morning, with breaks at times. Approximately 0.5-1 inch is expected in the interior through Monday, with more on the coast and in the mountains. Mountain snow is expected as well. This weekend will feature the first widespread mountain snow of the season, with 4-8” possible by Sunday evening at the passes (more in higher elevations). Additionally, winds are possible over the weekend. The forecast is still uncertain, but at least gusts of 25-35 mph are expected. Some forecasts have shown higher gusts, but that is not yet certain, so stay tuned!

November, which is typically the wettest & stormiest month of the year, has lived up to its reputation so far. 1.1 to 2 inches have fallen since Monday across the lowlands, and more is definitely on the way. 

Let’s start with the UW forecast for rain through 4 PM Sunday.


Expect 0.5-0.75” in the interior, with isolated totals up to 1 inch. Expect 1-3 inches on the coast and in the mountains below the passes.

The first widespread mountain snow of the season is expected over the weekend. Below is the UW model snow forecast through 4 PM Sunday.



Expect 4-8 inches of snow at the passes (maybe less due to rain/snow mix at the passes at times). Wintry driving conditions are possible at times in the passes, especially on Sunday. Higher in the mountains, upwards of 1 foot of snow is possible.

Breezy conditions, with gusts of 20-35 mph, are possible at times through Sunday. Some forecasts have indicated stronger storms, but at this time that isn’t expected, as uncertainty is much too high.

Below is the Federal Way forecast from Weather Underground.


One thing you might notice is that it will be cooler. Highs will reach the upper 40s to low 50s, with lows in the low to mid 40s. Expect rain each day (a common occurrence this month).

It will be quite a rainy week, as we are in a typical November pattern. The UW 1-week rain forecast is below.


This goes through 4 PM next Thursday. 2-3 inches of rain is expected in the lowlands, with more possible.

Active, rainy, and stormy weather will continue through the weekend and into next week. Stay tuned!
