THIS TIME I CAN PROMISE YOU SNOW IN THE TRIANGLE, BUT…
It will snow tomorrow, and rarely can I make a statement like that in the piedmont of North Carolina with such high confidence! In contrast to the event a few days ago, a deep layer of the atmosphere will be cooling and we won’t have to worry about warm air aloft. But I have other concerns relating to impact.
First of all, the morning rush hour will be fine. A little light rain, if that. The precipitation intensity should pick up a bit late morning as the atmosphere cools enough to produce snow. But will it come down hard enough to extract heat from a warm ground and allow the snow to accumulate on the roads? I have my doubts but it’s worth watching. Accumulations are more likely on grassy surfaces and there I could see half an inch to at most an inch.
Then tomorrow night, black ice warnings are already flying, and that could happen but consider this. As soon as temps go below freezing tomorrow evening, the air will begin to dry out. This will cause increased evaporation rates. It’ll be a race! Will the standing water evaporate before it can freeze, or will it freeze before it can evaporate? That is the million dollar question! If the water does freeze I think it would be after the evening rush hour, so at this point I think the commute home will not be all that bad.
So those are my thoughts at the moment. Will update as needed but not just for the sake of cluttering the Facebook landscape! Talk soon
