Two main factors played into the fact that we have next to no snow on the ground today: snow coming down light melting on the warm pavement, but the main cause was the dry air sinking in and soaking up the moisture. The switch from rain to snow happened just as planned, but that darn dry slot always will kill snowfall totals. Normally the dry slot is not as strong as what we saw yesterday, but was very powerful and was quite the sponge...soaking up the moisture. The Dayton International Airport did have 0.6 inches of snowfall yesterday, but nothing to measure sticking on the ground because it melted on the warm pavement. If the snow falls fast enough you can easily get it to stick to warm pavement though. Check the blog entry from Thursday, March 25, 2010...which has photos. It was a very similar situation where the pavement was warm...but we didn't have the dry slot. The two factors combined really killed us because since the snow was so light, it wasn't enough to stick. Blew that one...which you will not hear very often, but gotta own up to it.
The good news is that we will stay dry for the next couple days. Today we will only get to about 32 for the high, but mid 40's for the rest of the week and weekend. There is a slight chance for a few rain showers to the north for Friday and a better chance for little rain for all of us in the Miami Valley on Sunday as a cold front punches in for the first week of 2012. Stay warm and have a good one!
