First Call for Snowfall

An intense wind/snow maker looks more likely to impact the region later this weekend into the first part of next week.

The latest NAM puts a damper on snow totals. However, still not sold on its solutions either. I've seen the NAM do a surprising hiatus on an earlier system this winter season.

At face value, looks like an inch or so for Louisville based on its runs. Indianapolis could be looking at 8"+.

When does the low pressure really intensify? If it does so earlier, then a broad flow of warmer air will be transported into the region, keeping us in the rain.

I had thought that the low would really get cranking once it gets really near the Louisville area. The NAM says sooner.

We will be going into NOWCAST mode. A reliable short-range model that I will be using, especially for this event will be the RPM model, which outperformed the NAM in one of our earlier snow systems. Right now, the RPM would not be that reliable until we get within 12-18 hours of show time.

In the meantime, I've put out a preliminary estimate. I will put out a final estimate after reviewing the RPM and comparing it with surrounding weather offices on how precipitation types are faring.

FIRST CALL...

Louisville 2-4"
Indianapolis 7-10"
Bloomington 4-7"
Owensboro 3-5"
Evansville 3-5"
Cincinnati 3-6"
Lexington 1-3"

Additional snow showers will be possible after the steady snows end. That could spit out additional light accumulations. Furthermore, depending on where the heaviest snow bands set up could alter totals drastically for the above locations.
