Viper HD (10) colours indicate approximate intensity. They do not give exact thresholds or identify hail or mixed precipitation.

LibreWXR uses model data to distinguish snow from rain.

Combination	Possible interpretation
Extensive low cloud, little high cloud	Moisture near the surface, stratus clouds or persistent overcast weather.
Extensive high cloud, little low cloud	A possible approaching front, or high cloud without rainfall.
High cloud increasing, followed by middle cloud	Possible evolution of a frontal system. Follow how the layers change over time.
Extensive middle and low cloud	Moist air at multiple levels; precipitation may develop if there is sufficient uplift.
Extensive cloud at all three levels	An extensive cloud system that may accompany active fronts or convection; layers may be separated and do not by themselves confirm vertically developed clouds.
