From US National Weather Service Paducah, Ky.
Forecast snowfall totals (fortunately or unfortunately depending on whether you are a schoolkid or a meteorologist that has to go to work regardless) have increased slightly once again with this forecast update.
We now have 5 to 7 inches forecast along the KY/TN MO/AR border very slightly decreasing to 4 to 5 inches as you move north all the way to the Interstate 64 corridor. Snow is forecast to begin overnight and persist through the early evening Friday. A widespread 4 to 7 inches would be a major winter storm for this region with significant and widespread travel impacts.
There is always a window for surprises with winter storms, but the modeling and meteorological signals with this storm have been more consistent than normal and our confidence in the area receiving at least 2-3 inches (which is when you really start to see travel impacts) is very high. Take the time today to prepare accordingly and plan for significant impacts.
The maps included are the warnings (Winter Storm Warning for the entire area). The “top end” snow amounts factoring in errors and the “low end” snow amounts. You can see they are getting pretty close together which increases confidence for us that everyone will be in the “impact” zone.
Start and end times are also included.
