On Jan 25 2014, a mid-level shortwave moved across the region generating light to moderate snow. I have included screen captures of the 1118 UTC regional radar mosaic and surface observations…along with a 1120 UTC Snowfall Rate Product and surface observations.
It looks like the SFR product did not detect all of the snow that was falling around 11 UTC. But the misses can generally be described as either (1) the surface temperatures being too cold or (2) the probabilistic model, that is part of the calulations, indicating probabilities that were too low to determine if there was snow.
Once you know all of the details on how the product is calculated, I think this product did a good job at detailing where the snowfall was occurring.
The highest snowfall rates indicated by this image was around 0.3 to 0.5 inches which seems to be representative of what was occurring.
