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). This 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.
