Duluth, Minnesota – A cold stretch grips northeast Minnesota this week, with temperatures dropping into the 30s overnight from Monday through Thursday — threatening damage to unprotected outdoor plants across Duluth, the North Shore, and inland counties.
According to the National Weather Service in Duluth, sensitive vegetation could suffer frost damage as lows fall into the middle to low 30s Monday night and again Tuesday night through Thursday morning. While daytime highs rebound into the upper 40s and low 50s, the chilly nights remain a concern, especially for early gardens and crops in areas like Carlton, Pine, and northern St. Louis counties.
Winds will stay gusty at times, with northeast gusts up to 35 mph expected Monday night. That wind, combined with colder air funneling down the North Shore and into the Iron Range, could push real-feel temperatures even lower overnight. Residents in low-lying and rural areas should cover tender plants, bring potted items indoors, and monitor conditions nightly through midweek.
While frost is the main threat, brief sprinkles are also possible Monday and Tuesday. Most days will feature partly sunny skies, with Tuesday and Wednesday warming slightly to highs near 52°F. Wind gusts could top 40 mph on Monday.
Looking ahead, warmer spring conditions return Thursday with sunshine and highs near 62°F. Friday continues that trend, setting the stage for a milder weekend.
Five-Day Duluth Weather Snapshot:
- Monday: High 46°F, breezy, partly sunny

- Tuesday: High 47°F, slight chance of sprinkles
