Slippery Sunday?

photoOver the past few days, our team of forecasters have been keeping an eye on the forecast as there is the potential for snow this weekend. Our models are starting to come into better agreement now with a system that will move though the state on Sunday. This will bring a chance for widespread light to moderate accumulations across the state. As of now, totals look to be on the range between 2”-5”. There are a few things that we will have to keep an eye on regarding snow accumulations. The cold air will impact snowfall totals so depending on how cold it is, the snow ratios may need to be adjusted. Current think is snowfall ratios will be on the lines of 16:1 to 19:1. precipThis means that for every one inch of liquid precipitation, snow will accumulate to 16” to 19”. This is because temperatures will be very cold, so the snow will be very light and fluffy, and when the snow is light and fluffy it doesn’t take much of it to add up. In addition, the models are also indicating that this will be a drawn out period of precipitation. This may also enhance snow amounts and we will have to keep an eye on all these factors. For now, there is the potential to moderate snowfall totals on Sunday afternoon into Monday morning. We will continue to track this system over the next few days and will bring you the very latest on our Facebook page and right here at
