There's a chance for frost again tonight over parts of the Northland, after temperatures fell as low as 26 degrees in some areas early Friday morning.
The National Weather Service has issued a frost advisory from 2 to 8 a.m. Saturday for the Iron Range, International Falls, Grand Rapids, interior parts of the Arrowhead and much of Northwestern Wisconsin away from the shore of Lake Superior.
Temperatures are forecast to fall into the low to mid-30s over the advisory area, which may lead to areas of frost that could damage sensitive plants if they're left unprotected.
Temperatures fell into the 20s across the Iron Range and points north early Friday morning.
