Latest First 40F Or Below Low On Record
Meanwhile, Saturday morning was the first morning so far this season that had the low dip to at least 40F at MSP as the low got down to 38F.
That was the latest first 40F (or below) low on record for MSP, the previous latest being October 14, 2015. Out of the top ten spots, five of those have occurred within the past ten years.
Meanwhile, that also means that we haven't seen a frost yet in the metro, going off the basis that Frost Advisories are typically issued for lows of 33-36F. Only seven times has the first "frost" (low at/sub-36F) occurred after October 17th, and the lastest on record occurred on November 1, 1931. Most recently, the first frost in 2015 occurred on October 16, and in 2013 it occurred on October 19th. Last year? It was on October 4th.
