PORTLAND, Ore. (KOIN) – On Wednesday, we woke up with some winter temperatures in places such as Salem and Hillsboro, which saw temps in the lower 30s.
A few places were close to breaking a record low temperature, but at this time, there are no records from Wednesday. Even the coast, like Astoria, bottomed out in the mid-30s. The record over at Astoria was 34, so it was a close one.
We are on track for another cold morning on Thursday. A frost advisory is in effect for the Greater Portland area, with morning temperatures from midnight to 8 a.m. expected to drop to the upper 20s to mid-30s. Many locations will be in a freeze warning too, which means temperatures will likely fall below freezing overnight. You know the drill: take in the sensitive plants if you have them out. This will be more routine as we get closer to November.
You can see a handful of the weather models below depicting that cold air up and down the valley. This cold air will take at least a day to scour out so our temperatures will stay below average.
Overall temperatures should warm by the time we get to Friday. That means I wouldn’t count on another morning of frost this week.
