For what little it's worth, snow amounts are busting on the low end so far in OKC and Tulsa. NWS has already lowered their totals.
Not because of temps mind you, but because there's just too much dry air. It's causing the opposite issue (which michsnowfreak alluded to earlier) of the snow being that sugary type, which is very inefficient for accumulatiom.
It may or may not have any bearing on the eventual outcome for you guys upstream, but just something to be aware of.
