GOLDEN VALLEY, Minn. - Many areas of Minnesota have seen their first frost of the season, but not the Twin Cities. Minneapolis-St. Paul International Airport, where records are officially kept, has not seen its first frost yet this fall.

The average first frost is on Oct. 10. But this year, we have set a record for the latest first frost, which dates way back to Nov. 7, 1900 -- the first time records were kept.

The last time we had temps below freezing was on April 12 -- 205 days ago.

In addition, this is also the longest growing season on record.

So how rare is this year? Quite.

The latest frost we've seen in recent years was on Oct. 28, 2007. Before that, you have to go back to the 1970s when we had our first frost on Oct. 30, 1973.

Our urban heat island and our weather pattern are likely having an effect on our later-than-normal first frost this year.
