If you look at the radar plots at NOAA's site here

http://radar.weather.gov/radar_lite....oop=no&rid=cxx

there is no prediction for precip type, just the value of reflectivity
is given.

At Intellicast here,

http://www.intellicast.com/IcastPage...r&prodnav=none

they go further and predict the precip type. My question, does
Intellicast use some temperature input to allow them to differentiate
between precip types?

It just seems to me that reflectivity alone cannot determine precip
type accurately. For example, heavy snow and light rain could have
the same reflectivity, I'd expect, yet Intellicast clearly has a
distinction between the two.

Ideas? Stan
