Rain-to-Snow Changeover Earlier than Anticipated

Radar and observations are indicating that the changeover from rain to snow has happened. It was supposed to occur this evening, but now that it has changed over, I do anticipate snowfall accumulations to be higher than what is being shown on the models right now. In order for the models to recognize this unexpected changeover, I recommend not using the short range models until the 20z (2:00 PM CST) runs, which by then should have detected the early changeover.
