Dry and Cold for New Year’s Eve

Ever since the rains arrived this week (unfashionably late notwithstanding), it’s been incredibly mild across the metro area.

Temperatures have held steady in the 40s and 50s since Tuesday began, thanks to a warm southwesterly wind that’s been around for the greater part of the week. This past Monday has actually been the only day in the past week to see a below-normal high temperature (42 degrees). Every other day, beginning with last Friday, has seen highs above normal–a big difference from the cold temperatures we experienced earlier this month.

Tomorrow, we’ll finally be back on the minus side of average, with high temperatures expected to only reach the low 40s in the wake of today’s cold front. The day will be a dry one, with partly sunny skies throughout. Clouds will increase tomorrow night ahead of a weak warm front set to slide through Western Washington on New Year’s Day. Temperatures on Sunday will warm up a bit to around average (46 degrees), under drizzly skies.

The coming week doesn’t look nearly as wet as this past one (we received over 80% of this month’s rainfall in the last three days!), as most of the fronts that trek across our area will be much weaker in strength. Still, the weather won’t be quite as mundane as it was during the first week of December–for one, it’ll actually rain! What’s more, several models actually show some very heavy rain, along the lines of a Pineapple Express, drenching Vancouver Island and southern B.C. mid next week, meaning that if the models are off by 100 miles or so, it could get quite wet around here.

Better enjoy that dry day tomorrow…
