During the afternoon and early evening hours on 2/15/2016, a large area of rain covered much of northeast Kentucky and southeast Ohio as well as the western half of West Virginia.
An upper level disturbance then moved across the area during the evening and overnight hours with the rainfall mixing with and then transitioning to all snow.
I wanted to show how the SFR image performed during this transition. The image above is from 0220 UTC on 2/16/2016. At that time, much of the precipitation across West Virginia was still in the form of rain…with an area of snow extending from northwest Pennsylvania across central Ohio into southwest portions of that state.
There appears to be several observations of rain across Ohio with surface temperatures of 32 to 35 DegF where the SFR product indicated snow in the clouds. It does appear that where surface temperatures were warmer than 35 DegF, the SFR product did not indicate any snow in the clouds.
From an earlier post, I believe the SFR throws out snow when the model-based 10-m temperatures exceeded 33 DegF. Is this filter working in this situation?
