I have to say La and Texas are like siblings. We usually are affected by the same weather system.

It's the nam

The Skew-T over the heaviest snow has warm air advection moving over a possible source of cold air advection(north-northeast winds cool air advection may be a better word.). Anyways the reason why this is important is because if you get a warm nose to form above but you have heavy melting snow you will absorb latent heat and cool that column. However, if you have a layer of cold below where the snow refreezes it will release latent heat and warm that part of the atmosphere, but if you can introduce some cooler air from the north into that atmosphere it can counteract that warning keeping precipitation frozen. I'd imagine in a setup like this you could see a snow to sleet(or rain depending on depth) transition if a warm nosed formed(if one never forms and the upper level column stays below freezing then you don't have to worry about this at all lol.) but if you can get sufficiently heavy precipitation in that warm nose you'd see it change back to snow.
