The Thanksgiving Day Forecast


Thanksgiving is coming and with lots of people on the road starting tomorrow, so the forecast is important. Bottom line: a benign weather situation...but not entirely dry.


A front is now offshore and it will move slowly towards us during the day tomorrow, with rain reaching the western lowlands around dinner time (see graphics above). No big deal for us, but the rain will be heavy tomorrow on the western side of Vancouver Island. So travel should be fine for most of the day with no issues crossing the Cascades.

Thursday looks like a wet day as a warm front moves up the coast (graphics). Thi
s warm front is associated with low moving NEward to our south. It will be quite wet on the SW side of the Olympics and the Skokomish could flood (AGAIN!). The low will bring moderate to strong winds (30-40 mph) along the central Oregon Coast and will open up and weaken as it moves inland late Thursday.Behind the system the temperatures will cool and showers will continue on Friday...but mainly over the mountains. Snow level will come down and the snow level will hit the passes. So be ready for some white stuff if you crossing the mountains on Friday. Good day for shopping on Black Friday.

Right now it looks like we might have a big, big treat next week with a ridge from heaven....but we will wait to talk about that.

Special Lecture: I will be giving a noon-time weather lecture ("Is Rainfall Getting More Extreme?") and a book signing at Elliot Bay Books, December 2 at 12 PM. Downtown in Pioneer Square.

My mulching mower works much better if the leaves are dry, and cleaning the gutters is harder to ignore-gotta work off the turkey somehow. C'mon high pressure!

After a vigorously satisfying round of storms I shall welcome a "Ridge from Heaven" rake up the debris and finish laying the gardens to rest.

A dry ridge would be lovely at this point. But then will that bring fog? I'd rather have the weather we've been having instead of being in that split pea soup!

Bonnie Story said...

Oh, goody! A ridge would be most useful for chimney-sweeping and other firewood related activities. That's great, I'll stay tuned... I love your blog!!!!!

Sorry about your wet Thanksgiving down sound. Up here in the San Juans it was wet overnight, but has been dry all day, and clear much of the day after some morning fog.

Wind started picking up at Blake Island (SW of Seattle) this afternoon, currently blowing constantly around 20 kts.
