Obviously not all masks are equal either. I use the 3M 8577 P95 ones.

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.
