The final morning of summer starts chilly throughout the state and frosty in the Arrowhead, but 60s and 70s return by the afternoon.
Under clear skies and light winds overnight, temperatures plunged across Minnesota. Most of the state is waking up in the 40s Wednesday, but portions of central and northeastern Minnesota are seeing 20s and 30s.
Most of the Arrowhead is under a frost advisory until 8 a.m., and a number of spots there have recoded temperatures below freezing.
Temperatures rebound quickly during the day thanks to sunshine and southerly winds. Almost all of the state makes it at least into the upper 60s, and western Minnesota, where the warm wind pattern will be the most persistent, will see widespread 70s.
This puts highs very close to average as we transition from summer to fall, with the new season beginning at 2:20 p.m.
Pleasant fall weather continues through the weekend, with limited rain prospects.
That extended forecast will be updated around 9:30 a.m.
