Plain English Campaign PEC criticised the Met Office for using the phrase "probabilities of precipitation" instead of "rain is likely". The Met Office responded by explaining that precipitation does not mean only rain. A Met Office spokesman said: "Precipitation covers a wide range of stuff falling from the sky including rain, sleet, snow, hail, drizzle, and even cats and dogs – but sums it up in just one word."

Backscatter diameter of the target multiplied by its inherent reflective properties, provided the wavelength is larger than the particle diameter (Rayleigh scattering). Water is almost 4 times more reflective than ice but droplets are much smaller than snow flakes or hail stones. So the backscattering is dependent on a mix of these two factors. The strongest backscatter comes from hail and large graupel (solid ice) due to their sizes, but non-Rayleigh (Mie scattering) effects can confuse interpretation. Another strong return is from melting snow or wet sleet, as they combine size and water reflectivity. They often show up as much higher
