If clouds are able to break up enough tonight, then we could see a patchy frost threat develop early Friday morning over parts of the Northland well inland from Lake Superior with a chance for temperatures to fall into the mid 30s to around 40 well inland from Lake Superior, but if clouds stick around, then temperatures will be in the 40s to around 50.
Note — No frost tonight in Duluth or Superior.
Warmer temperatures return to much of the Northland on Friday with highs in the low to mid 70s with temps near 80 even possible around the Brainerd Lakes area, but temperatures will be cooler farther east near Lake Superior with highs mainly in the 60s on Friday.
