Be careful with automatically cutting snowmap snow totals just do to sleet.
1. Like November models tend to under do front end dumps. Almost every SWFE ends up under modeled. So that should lessen how much you cut from a snowmap.
2. The 1st hour or 2 of mixing it WILL still accumulate, obviously though less than 10 to 1.
So if a snowmap states say 5. Do not automatically cut 3. I would go 4 of sleet snow mix.
I REALLY hope we avoid a major ice storm. Last March a tree fell on my house due to a 10 in her in early March. No more havoc pls.
