The Week Ahead – Turning Wet with Mountain Snow, and Maybe a Windstorm?

[Article by Ryan Porter of Snoqualmie Weather]

It’s been a chilly but at least sunny start to Sunday, however wet weather looks set to return this week.  With highs likely to run 5-8°F below normal for early November in Snoqualmie Valley, we should see chilly rains in the lowlands and mountain snow down to all pass levels.

Northerly flow should turn more onshore on Monday.  A cool showery pattern should be associated with an initial front late Monday into Tuesday.

Wednesday and possibly early Thursday should see some break from the rain, before a more significant system moves in later Thursday into Friday.  Some earlier model runs had a significant Low barreling through northern WA or southern BC, with the potential to set up a 12-15 mb pressure gradient between Portland and Seattle.  We’ll keep an eye out! 

This would be cause for major concern as far as potential for widespread damaging winds (50+ mph) and power outages to the Puget Sound area.  However, looking at longer range model runs this doesn’t look like the odds-on bet (at least not yet) for ~Thursday-Friday.  More than likely the tail end of the workweek will just end up rainy and breezy, but something to keep a close eye on for sure.

For next weekend, a cool showery pattern looks to resume.

Get that winter gear ready!  Hopefully The Summit will be able to resume lift tickets here shortly.

Most importantly, we need to give special thanks this week in honoring and thanking our military veterans who have served in the United States Armed Forces.

Have a great week!
