Here We Go Again

As Aaron mentioned yesterday, there is some big uncertainty about the next storm system that will plague the state. Well, things are becoming a bit more clear this morning and you are in luck if you like snow. Now, Im going to go ahead and say right off the bat that we are not expecting a blizzard like we saw a couple of weeks ago by any stretch of the imagination. However, the forecast models have really come together over the last 12-24 hours and are all beginning to agree that parts of South Dakota will get atleast a couple inches of snow. Below is one such model. This is a snowfall accumulation map for the Eastern United States over the next 4 days. With the legend down at the bottom, you can see how much snow this particular model is predicting.

Using a complex formula to figure out snow to liquid ratios, the model thinks that there will be a swath of snow where we recieve anywhere from 1-6" of the white stuff. Now keep in mind that this is just one of many models, all of which say a little something different and all have their own tendencies. For instance, this models tendency is to be too high on snowfall amounts. So this model's forecast is not set in stone. But, combining all of the models's outputs, the National Weather Service has come up with a forecast for the tri-state area.

They are calling for a swath of 1-2" of snow. That seems a bit more reasonable and I am going to agree with them for now. But remember, things can change very quickly so stay tuned to KDLT or this blog for further updates down the road.
