Saturday Snowfall Forecast Verification
Enhanced Areas Identified But Snowfall Under Forecast
Reality Versus Eastern Mass Weather Forecast Map
In order for a snowfall forecast to be truly elite, it is necessary to not only be highly accurate on a qualitative level (identify areas of heavier and lighter snowfall), but obviously it also needs to provide an accurate quantitative assessment of precisely how much snow will fall. When comparing the forecast to reality yesterday, it is apparent that the forecast was very accurate in the diagnosing which areas would be heavily impacted, while leaving much to be desired in that it greatly underestimated the snowfall in said areas.
Dual Areas of Focus For Enhanced Snowfall
The forecast on Friday identified one area of heavier snowfall associated with an inverted trough over central areas of the forecast area, and another zone of ocean-enhanced snowfall along the north and south shores of the Boston area. The placement of these areas nearly perfect, however, amounts were more on the order of 8-12"+ as opposed to the 3-6"+ that was denoted. Granted this was a very difficult forecast, that is a rather large discrepancy that had major implications for those impacted.
