FIRST CALL FOR SNOWFALL (text only)

Using a blend of models and QPF potential, I came up with a range of possible totals. I call this my Mid-range Highest Probability blend. Usually in storms like this, had a 80% effective rate last year. This is a tough storm but have found that at about 36 hours out, this blend usually performs most accurately than one 24 hours out.

I will have a map posted later...

Louisville 1-2", closer to 1" further north toward the river
E'town 2-3"
Bowling Green 2-4"
Lexington 3-5"
Jackson 6-8"
Pikeville 6-10"

Much of this snow may be impacted by surface temperatures, daylight, and temperatures. The heavier the snow, the better it can overcome these obstacles.

Also, there could be an area where a prolonged episode of heavy snow will occur. This could lead to dramatic accumulations of a foot or so. Stay tuned as pinpointing this possibility won't occur until Nowcast mode.

Locations east of Lexington should expect difficult travel, possible power outages, and some roof collapses due to the weight of snow on power lines, tree limbs, and flat rooftops.

This may not happen but always best to err on the side of caution. I wouldn't expect any roof collapses unless accumulations exceeded 9". Roof collapses would be confined to car ports, that kind of thing. If accumulations should exceed 12", roof collapses to hardware stores or other retail stores could be possible.
