Good morning and happy Thanksgiving everyone! Only a single day after we enjoy our family’s company and our turkey dinners, we’ll face a bout of early winter weather.
Very cold air will begin filling in on Friday, just as a rain event will be ending. This will result in a snow chance for Friday and Saturday. Accumulations will likely be light across the area, below 1 inch.
Keep this in mind when traveling from your Thanksgiving gatherings!
Things are kicking into high gear this week for Northwest weather. There’s a number of meteorological elements at play; but the bottom line for folks planning their Thanksgiving week is that it’s going to rain..a lot. A Flood Watch and Hydrological Outlook have been issued by the NWS concerning rivers along the Cascade and Olympic mountains that could reach flood stage by midweek.
I’m going to stick with the upper air “terrain” metaphors for this atmospheric setup because it’s a tricky one. These are the different parts of our meteorological puzzle for this week’s rain event:
The atmospheric river trudging around the hill of high pressure is directing copious amounts of moisture into the region while a wave of warm air saturates the upper levels and milks out every drop of rain onto Washington, mostly onto the mountains. As we get to Thanksgiving and later into the week we’ll see some cold air start to envelop the warm moist air, bringing even more rain late into the week.
Tuesday: Heavy, persistent rain dousing the region in the morning. Scattered showers towards the end of the day.
Wednesday: A lull in the weather, mostly dry. Rain begins late at night.
Thanksgiving: It’ll be a soggy Turkey Day, with widespread scattered moderate to heavy showers starting early and lasting throughout the day.
Friday: Rain begins early yet again but fizzles out.
Weekend: Colder air returns, and moisture mostly evacuates.
**Note** Some website forecasts are calling for chances of snow in the lowlands this weekend, however due to the length of time away from the weekend, forecasters are stating “low confidence” in any snow predictions. If there’s a snow event more possible or imminent, you’ll see it posted here on the Puget Sound Weather Geek.
November 23rd 10:30AM: Good morning everyone! We’ve got some crazy weather just south of Puget Sound along the WA/OR coast. Multiple tornado warnings have been issued as strong thunderstorms move onshore harboring strong rotation and possible waterspouts/tornadoes within them. Continue reading

We’ve stepped into the week before Thanksgiving, and nature’s here to remind us which season we’re in. Our big protective hill of high pressure has broken and moved out; which means things are going to change fast. Out with the chilly temperatures and cloudless skies, and in with the all too familiar overcast, rainy, and breezy. Continue reading

We’ve finally received a much needed break from the rainy and stormy weather! A big hill of high pressure developed as Thursday’s storm migrated away. The surface pressure rapidly increased Thursday night and caused high winds to persist much longer than predicted. Winds gusted to over 40mph at Three Tree Point well after 6pm. Continue reading
