The NWS is forecasting lows in the single digits at Lake Placid. That some areas could be below zero is well within the realm of possibilities.
Accuweather and TWC are moderating the forecast after the fact because it is an extreme event. Time will tell. I have a feeling it wont be nearly 20°F warmer than the models predict like TWC thinks.
Being media companies, one would expect them to exaggerate this event, not tone it down.
I know Accuweather operates their own model that tends to moderate the other models, which is worthless in extreme events. TWC also provides their own unique forecasts...
Even so the NWS is showing lows for the 6th to be about 5°F above the model above.
