Well I would like to know the conditions that resulted in the downslope occurring. In most storms this is not an issue. In order to do that I would have analyze the storm and look for, understand, and come up with conclusions with the data. Here is the incomplete possibly flawed understanding I have of what occurred. Winds at the surface were coming from the northeast while winds further up would have been coming from the south. Beartown Mountain (part of Clinch Mountain) at a height of 4688ft presents a barrier for the lower levels of the storm almost reaching the 850mb level. From my understand the mountain took the immense amount of moisture from the storm and channeled it up it's slope causing orographic lift. This resulted in a lot of condensation that released a ton of latent heat into the air. Because the air was coming from the south at the 850 level the winds continued beyond the mountain spilling into the Clinch river valley just in time for the storm's arrival up here. This layer of warm air however critical to the amount of snow accumulation would be shallow due to the stubborn cold NE winds beneath it at the surface and only partially melt the snow crystals resulting in graupel. This I believe is a good theory as to how this occurred however numerous storms have taken a similar track and not resulted in this. This I believe in part was caused by the exact circumstances of this event which I have no idea of knowing and also in part by the warmer than modeled air the storm brought up the valley. It may not have been able to change the precipitation type here on it's own this far up but it certainly could have helped the downslope effect. Also of note early into the event I faced my 1st less influential enemy virga. I don't have any precise answer for that but my reasoning is the winds from the NE brought with it dryer air near the surface that would keep the relative humidity tempered down. In total it took almost 3 hours of moistening the atmospheric column between seeing snow on radar over me to see light precip reaching the ground from 9 to midnight. Anyway after many hours as the storm pivoted winds changed direction and the downslope effect weakened resulting in me making a full transition to snow in the late morning and early afternoon before switching back to a mix near the end of the event at the warmest time of the day when it was 33. Even with all this chaos and factors working against me I still got some snow though. Wow.
