NEW SNOW NUMBERS...

January 10, 2020

Some new snow numbers to pass along. These are not forecasts, they are raw model output which we use to make forecasts. Again, it's this data which helps us establish the trends necessary to make the actual forecast. As you will see, there is variance among the models tied to track and intensity. However, 3 of the models depict the heaviest snow from far NW Illinois back into eastern Iowa. I feel that is likely a trend to lean on. Also keep in mind, models tend to be on the high side with snow totals so at least in spots these could be several inches high. In other words, I'm leery of those 15-17' figures.

I'm also throwing in some freezing rain or sleet accumulations, a factor which could become an issue in the southeast half of my area. especially from the Quad Cities southeast. Due to all the sleet, ice, and even some rain that really cuts into the snow potential here. The ice issue could become significant. Enjoy and roll weather...TS
