Will tonight be the end of the growing season?

Posted on September 17, 2010 by Andrew

The Northland has seen several nights of frost advisories so far this month, but for tonight the National Weather Service has issued the more-severe freeze warning for much of the region, including the Iron Range, International Falls and the interior Arrowhead. A frost advisory is in effect for the rest of Northeastern Minnesota, including Duluth.

Temperatures in the warning area are forecast to fall into the upper 20s overnight, with light winds and under mostly clear skies.

Here are the specifics from the Weather Service, starting with the warning:
