We’ve seen a lot of anecdotal evidence of a cooler than usual summer in many parts of the Northern Hemisphere. This one caught my eye though, because I can’t ever recall of hearing a freeze warning being issued for this region before Labor Day.
Here are the normals and records for Monday, August 25th:
THE DULUTH CLIMATE NORMALS FOR TOMORROW
NORMAL RECORD YEAR
MAXIMUM TEMPERATURE (F) 72 95 1888
MINIMUM TEMPERATURE (F) 52 40 1950
It looks like a new record could be set for Duluth, and likely Ely, also.
Here is the latest warning from the NWS in Duluth:
