Good evening. Rain, snow and high winds are increasing across Central and Eastern Kentucky as Sandy begins to have a major impact on our weather. As precipitation increases, temps will start to fall this evening, and snow will mix with the rain in the east. Heavier precipitation will then move in overnight, and that will pull down even colder air and result in more snow.
The afternoon runs of the NAM and GFS are trending colder quicker, and that ups the chance for snow. The folks at the HPC have expanded the risk area for tonight and Tuesday:
My snowfall forecast remains unchanged…
The prime time for accumulating snow will be from midnight to 10am with the greatest concentration across the east and southeast. Again, we are dealing with warm ground, so a lot of snow will be melting. Still, it will snow faster than it can melt at times, with elevated surfaces faring the best. I’m not expecting a big impact on roads, except for the higher elevations.
Here’s regional radar to track the drops and flakes:
More updates later tonight. Take care.
