SNOW UPDATE: Temperatures are tumbling rapidly behind the cold front this afternoon. Rochester dropped 20° in an hour and will continue dropping into the evening hours. A reinforcing wave of energy will support a surge of widespread precipitation returning around nightfall. Any rain will quickly transition to a period of sleet and then snow, which could be heavy at times.
Right now, it appears the window of snow will favor 8pm-1am (give or take), so it's quite limited. That said, it'll be wet & heavy during that time, so several inches of dense snow accumulation will be possible. Also worth noting, our temperature drop will present additional travel issues as a layer of black ice could be masked by this snow accumulation.
This will be far from a snowstorm. While the snow totals won't be particularly impressive, the prospect of icy travel & continued strong wind gusts will make for a very wintry night across WNY. The landscape will look VERY different around here by tomorrow morning.
