Frosty Friday temps could cause damage to plants in the PNW
PORTLAND, Ore. (KOIN) — Another round of frosty morning temperatures could cause damage to sensitive plants along the Willamette Valley Friday morning.
Another round of clearing skies and colder overnight lows is expected along the Willamette Valley late Thursday into Friday morning. Temperatures will likely remain above freezing, but frost is still likely. Sensitive plants and pipes should be protected during these chilly morning temperatures.
The first round of cold air was felt across the region Thursday morning as Portland saw its coldest temperatures since April 18, 2024.
The Portland National Weather Service has issued a Frost Advisory for much of the Willamette Valley and parts of southwest Washington late Thursday to 10:00 a.m. Friday. Portland is expected to miss out on the frosty temperatures, but cooler morning lows are still expected.
A Freeze Warning is in place through the mid-morning hours Friday just north of Mt. Hood. That's where temperatures will likely fall into the mid to upper 20s.
Covering or bringing sensitive plants indoors will help prolong the growing season another day. These early morning cold snaps will continue to become more frequent as the autumn season marches towards winter.
Mild afternoon temperatures are expected across western Oregon and southwest Washington as winds become gusty Friday after sunrise.
