MSP has had accumulating snow in late September and early October before...as recently as 2.5” in 10/12/2009. This will be the most for so early though. 1.7” on 9/26 is lol though.
If it was 30° and 1/4SM +SN on August 31st it would start sticking then too. MWN has had accums in July. Technically the solar radiation is higher up there than at lower els since there’s 6000ft less of atmosphere to scatter it.
I burn with a UV index of 2 and I can’t even muster a hint of red this time of year.
The twin cities got nearly 30” in Halloween of 1991. How quickly they forget. Although he was probably watching Saturday morning cartoons back then.
