The remnants of Hurricane Zeta will pass south of Connecticut Friday morning. As the storm tracks to our south, Canadian cold air will filter south into our area at the same time.
This will result in heavy rain Thursday transitioning to some snow late Thursday night and early Friday morning.
As for accumulations? Some minor accumulation is possible in the hills of northern Connecticut, while most will only get some wet snow that might coat the ground.
You may be wondering how common this is? It's actually quite uncommon if you focus on the Hartford area. In the last 115 years, the Hartford area has only seen accumulating snow a total of five times.
Behind the precipitation will be a very cold airmass that will settle in for Friday evening. A flash freeze is possible Friday night and Saturday morning.
Temperatures by Saturday morning will fall into the 20s statewide resulting in a killing freeze to any tender vegetation.
