Have you winterized your home and/or yourself yet? Are you stocked up on food and beverages, and have you gotten chains or snow tires, or that generator you’ve been wanting yet?

We ask, because Normandy Park resident Michael Snyder – aka @SeattleWXGuy – has posted some updates on the potential for cold winter weather and snow for the region coming up, possibly starting with a White Christmas this Saturday.

Snyder works as an Alaska Airlines Aviation Weather guy/Flight Control, and is a longtime METAR instructor, Aviation Instructor, as well as former National Weather Service behind-the-scenes guy. He knows his weather.

“Seattle White Xmas watch!” Snyder Tweeted. “New EURO: SeaTac showing 0.9” of snow in previous 24 hours total at 10pm Christmas night, temperature falls below freezing between 4-10pm. We need 1” on the ground for a White Christmas, It’s going down to the wire!”

Here’s a video Snyder posted on Wednesday, Dec. 2021:
