7 Day Forecast
So far today...
Updated Sunday 5:40 p.m.
After a very stormy start to our Sunday (thunder! lightning! a tornado warning! Oh my!), things calmed down considerably over Puget Sound by afternoon. Most of the shower action post-lunch hour stayed in the Cascade foothills, allowing for a dry and partly sunny day for the Twelves enjoying the Seahawks game at Century Link Field. Highs climbed mainly into the 50s, several degrees above the upper 40s that are average for this time of year.
The passes continued to pick up snow, so travel over the east-west Cascade routes was still tough at times. The high country snow and lowland showers will taper off overnight, and with partly starry skies, we'll drop into the 30s in the cooler pockets of Puget Sound by dawn. Watch for some fog, especially in the South Sound, for the early morning commute.
Another system moves toward the Northwest by the afternoon, so look for increasing clouds and rain later in the day as the warm front nudges in. Highs will still climb into the low 50s in Seattle and Tacoma in spite of the increasing overcast.
The cold frontal portion of this storm drives through by Tuesday, so the rain will stick with us most of that day as well. With lowland highs well into the middle or even upper 50s, we'll see the snow level jumping all the way up to 7,000' by mid-week. The passes will be easier to cross as they'll be wet rather than white, but unfortunately the ski resorts will pick up more rain than snow, too.
Wednesday is naturally a big travel day, and it actually looks decent, weather-wise. We'll be between storms, and other than a few showers, it (at this point) looks mainly dry on the roadways.
Thanksgiving itself looks rainy again--all the better for staying indoors eating turkey and watching football!
Have a great night,
