I don't think it will matter much with melting. It's not like the soil is 45F vs 30F. When it starts melting it's ice water anyway and the surface hangs around in the low/mid 30s depending on solar. My 4" and 8" soil hasn't been below 33F all season and it still takes forever to melt.
Insolation and temps/dews determine most of the melting. 45F and March sun don't care how deeply cold your ground is.
1.8”/0.31” in the latest sample. Didn’t see much sleet in it either so it was really a rimed, dense snow. 3.9”/0.47” as of 630am, but over 4” now.
