You've certainly noticed a cooler trend the last few days across Minnesota.  Now it's coming with a warning.

The National Weather Service has a frost advisory across much of Minnesota, and a freeze warning north and east of Hinckley. Temperatures are expected to drop into the 30's and even 20's over the northern portion of the state.  The warnings are in effect from 1:00a.m. to 7:00a.m. early Thursday morning.

WCCO Meteorologist and 3:00-6:00p.m. host Paul Douglas says from Willmar, to St. Cloud, to Duluth and the Arrowhead, you should expect it to dip below freezing.  

Frost advisory posted for much of Minnesota, including MSP metro. I doubt suburbs will see frost, but odds are much higher from Willmar to St. Cloud. Frost prevalence will depend on how fast skies clear late tonight. PS: no correlation between early frost and severity of winter pic.twitter.com/ramd3DS9IF

While the frost advisory won't quite make it to the metro area, it is close enough that you should take precautions with any outdoor plants and gardens.  Anything sensitive could be in danger of being killed with temperatures reaching the 30's overnight.  

This is definitely earlier than normal.  Depending on what part of the state you're in, we're getting this cold two to three weeks earlier than average.

The cold weather overnight is on the heels of the coldest ever high temperature on September 8th in the Twin Cities of 52, and possibly the coldest ever high temperature this early in September with the expected high of 51 on September 9th.  

However, there is good news on the horizon as temps will steadily be climbing back up towards 70 degrees through the weekend and into next week.  Paul Douglas says it's possible we even get back to 80 with the way the long term forecasts are looking.  

And as Paul notes in his tweet above, cold this early is no indication that a colder winter is coming.  Fingers crossed.
