Updated Thursday at 9:30.... The new run of the NAM is coming in and the snowstorm chances are increasing. We don't get too many heavy snows in Louisville so I always call 4 inches a snowstorm and there is a chance we could get this much.
Earlier today, the NAM had the least snow of the models and now it is having the heaviest amount along the Ohio River.
The map shows over .50 precip. from 7 PM tomorrow to 7 AM on Saturday. In Louisville this will start off as rain but go to snow by mid or late evening. So if the NAM verifies, we are looking at 3-4 inches of snow tomorrow night.
The HPC 4 inch snow risk issued late this afternoon had a low risk for Louisville and a moderate risk from Madison to Cincinnati.
On the right is the 8 inch snow risk which is low from Madison to Cincinnati.
These maps will be updated in the morning and the 4 inch snow risk may be expanded as the system appears to be getting stronger.
The HPC also has a 60-70% chance for at least one inch of snow in Louisville.
