Coldest Night So Far This Season

And yes, the winter season is still young, but overnight lows in the teens across the majority of the state will easily eclipse our previous coldest night of 25 degrees in Richmond on December 29th. The wind speed will decrease significantly as the night wears on, but even a 3 mph wind at a temperature of 19 degrees will result in a wind chill of 15 degrees. We'll have one more breezy and cold day on Wednesday before a nice warm-up heading into the weekend. A few central Virginians were treated to snow showers this afternoon, but any significant wintry weather might still be quite a stretch away. There are two chances that I see over the next 10 days for wintry weather in and around metro Richmond, and they are both associated with similarly structured storm systems. The big question for each of these systems will be whether or not the air mass will be cold enough to support snow. Most of the rain will be gone by the time the cold air moves in during the first event this Sunday, with still a lot of uncertainty with the second system slated to arrive next Thursday the 12th. Neither system looks impressive at this point. I'll keep one eye on the models tonight, and the other on the Hokies down in New Orleans. Hopefully they can put Michigan away and spread a little warmth north. I'll have another update tomorrow. -Zach
