It's not often we get snow on Christmas, and it's even less often that we get it two years in a row. Last Christmas, the middle of the country was graced with a powerful storm that spun into the area, sat on Iowa for a while, and went on its way, giving millions of people a white Christmas. Although we didn't measure much snow from that system, it was impressive and memorable. Here's a link from last year's post.
This year's storm was a different beast. It was faster, and gave us a beautiful wet snow all day Christmas Eve. We were in Rolla visiting my family, and watching the snow falling slowly through the bare trees was awesome. I took the liberty of bringing one of my extra rain gauges on our travel to measure the water content of the snow. It was a wet 9.3 : 1 ratio. Contrast that to the nearly 20 : 1 snow we had on the 11th. Geez, if this snow had that ratio, our snow total would have more than doubled. That made me wonder on our trip home...what is/are the factors that affect this ratio? I assume primarilly temperature. I also assume that one could accurately predict the type of snow based on this factor, which could end up saving cities money on salt/cinder they throw on the roads...but I digress.
In Rolla, I measured 2.8", which melted down to 0.30". In Fulton, we ended up with 3.5" melting down to 0.37". The roads are great...dry in fact, which I presume is a result of the wet snow. That's what led me to my inquiries above during our drive home today.
