Another arctic front and associated precipitation moved across the region on Tuesday (Jan 12, 2016). The airmass was cold enough that the precipitation generally began as snow and remained as snow during the event.
A band of heavier snow developed along the arctic front as it pushed across Ohio into Pennsylvania and West Virginia. When comparing the SFR image and the radar, the SFR product picked up the band of heavier snow quite well across southwest Pennsylvania. Some places in the heavier band of snow in Pennsylvania reported visibilities of 1/4 mile.
The band of heavier snow extended southwest along the Ohio River across southeast Ohio into Kentucky with some visibilities of a mile or less. However, the SFR product did not seem to pick up the band in southeast Ohio or Kentucky as well. In fact, it seemed to miss the snow in Kentucky all together.
Based on the radar mosaic, it appears the band of snow across southeast Ohio and portions of Kentucky was generally as intense as that across southwest Pennsylvania. However, the band in southeast Ohio and Kentucky was not as wide. Could this be part of the reason for the SFR not indicating as heavy snow in southeast Ohio and Kentucky?
