I've been asked why, if I am forecasting accumulating snow and ice (scroll down), there aren't winter weather forecasts on the NWS map. Good question.
Here is the NWS's forecast for Salina, Kansas, (where I-135 and I-70 come together, an important highway junction for travelers):
I can't speculate as to why there are no "winter storm" (my words) colors on the map in the area with the question marks. Regardless, I recommend that cross country travelers do what they can to either travel before the storm or otherwise mitigate its effects.
