PORTLAND, Ore. (KOIN) — Temperatures dipped below freezing overnight into Monday, bottoming out at 29 degrees at Portland International Airport and breaking the old record which was set in 1963.
Oct. 26 also marks the coldest morning since March 17 in Portland. Several other cities in the Willamette Valley started the day in the 20s as well. As the day continues, expect sunny skies and highs in the mid-50s.
Temperatures will gradually warm this week, with highs in the upper 50s on Tuesday and in the 60s on Wednesday and Thursday.
We’ll also remain dry through Thursday, with areas of morning clouds and ample afternoon sunshine. However, a weak front moves through Friday, bringing rain in the afternoon or evening. The good news is we dry out in time for Halloween, with Halloween night looking mostly clear with temperatures in the low-50s to upper-40s.
