The temperature will play a major role in determining the severity of an approaching winter storm.
National Weather Service meteorologist Mark Britt said Monday that the metro-east is likely to get 2-4 inches of accumulation in a storm that will start late Tuesday and extend into Wednesday, alternating between snow showers and rain.
“But there are some projections that we could get much more snow,” Britt said. “The reason for that is the temperature. We’re right on the borderline and if it’s a couple of degrees cooler we could see less rain and more snow.”
The high temperature is expected to be 35 Tuesday, Britt said. Every degree lower puts it closer to the freezing mark and trades off rain drops for snow flakes.
