News 12 Meteorologist Mike Favetta explains inaccurate snow accumulations forecasts

With minimum sampling and spare observations, Favetta says the data going into the computers wasn't very good (3/3/14)

BROOKLYN - News 12 Meteorologist Mike Favetta says many missed the mark on today's snow accumulation predictions.

Favetta says unusual agreement among most forecasting tools Thursday night led to a high confidence in large snow totals for New York City. One key that all models missed was just how cold the air was going to be, meaning that the fine, powdery snow that resulted was blown around like dust.

Another issue in predicting the intensity of the storm was that on Thursday, the storm was over the Pacific Ocean. Once it reached the mainland around Saturday morning, forecast snow amounts dropped continuously for the remainder of the weekend.

With minimum sampling and spare observations, Favetta says the data going into the computers wasn't very good. Therefore, the forecast was flawed until Saturday night, which is when the good data from the ground started coming in.
