"Thanks for the info on the scarp 2, but it seems as if snow would blow up through the fly since it is not attached at the bottom"

Due to popular demand, Henry has already fixed that on the Scarp 1 and I think that it will be done on the next batch of the Scarp 2 as well.
Having the fly down to the ground increases condensation, so Henry has designed the new version with vents at each end as well as an easy to slide up the main pole fly , so that you can choose how much ventilation you get.
Keep in mind that below about 40f , humidity makes us feel colder , so often is better to have some air movement inside the tent.
