If you compare Precipitation type layer to observations, there is some chance that ECMWF forecast does not match these observations.
A prediction is not a report.
But this layer and the local forecast by ECMWF are consistent.

What model did you use for Precipitation types?
Then are you talking about your own observations or the model snow forecast?

I had a feeling the color shade was wrong in the legend, but when I looked up current weather in the white areas, it was not currently snowing in those locations.

White is in the legend even it is a sort of light gray to make the word “snow” in white letters readable.
Grey is where there is no precipitation. This is quite obvious.

Those colors are not in the legend, so may I ask what those colors represent? I assume the dark gray represents no precipitation, but when I look up the current weather in the white areas, no precipitation exists there as well. Freezing point doesn't seem to be a factor either. Thanks! Screenshot 2025-01-11 120440.png

However, my primary complaint is that "Rain" is colored as light blue, which is often associated as snow on many other precipitation type maps offered by other services. I would suggest changing the color of Rain to green to be consistent with other maps to avoid confusion.

Premium is usually updated 4 times per day and you can check data with 1h step. Free offers 2 updates and 3h steps.

may I ask the algorithm behind this new overlay? I'd like to use the same algorithm to calculate the type of precipitation in my country. I'm running WRF model for my research activities at the Iskenderun Technical University. Thank you very much for your response in advance.
Happy new year to all.

Will it [freezing] RAIN, SLEET or SNOW?

Wikipedia puts it this way:

HAIL is a form of solid precipitation. It is distinct from ice pellets (American sleet), though the two are often confused. It consists of balls or irregular lumps of ice, each of which is called a hailstone. [...] Unlike other forms of water ice such as graupel, which is made of rime, and ice pellets, which are smaller and translucent, hailstones usually measure between 5 millimetres (0.2 in) and 15 centimetres (6 in) in diameter.
In more detail: https://en.wikipedia.org/wiki/Hail

GRAUPEL (from German language), also called SOFT HAIL or SNOW PELLETS, is precipitation that forms when supercooled water droplets are collected and freeze on falling snowflakes, forming 2–5 mm (0.08–0.20 in) balls of rime. Graupel is distinct from hail, small hail and ice pellets: the World Meteorological Organization defines small hail as snow pellets encapsulated by ice, a precipitation halfway between graupel and hail.
In more detail: https://en.wikipedia.org/wiki/Graupel

ICE PELLETS (American: SLEET) are rain drops that have frozen before they hit the ground. When they hit the ground, they bounce. Ice pellets are also called sleet and can be accompanied by freezing rain. In winter, precipitation usually begins falling out of a cloud as ice particles.
In more detail: https://en.wikipedia.org/wiki/Ice_pellets

FREEZING RAIN is the name given to rain precipitation that freezes on contact on surfaces maintained at temperature below freezing by the ambient air mass. Unlike sleet, a mixture of rain and snow, ice pellets, or hail, freezing rain is made entirely of liquid droplets. The raindrops become supercooled while passing through a sub-freezing layer of air hundreds of meters above the ground, and then freeze upon impact with any surface they encounter...

We don't actually have a "hail" icon nor a layer for it. Hail normally occurs in rainstorm or thunderstorm, and is the result of strong updrafts that repeatedly carry growing chunks of ice upwards into the clouds. Unlike freezing rain, graupel or ice pellets (that are softer and smaller in size), hail is hard as stones, bigger in size and causes extreme damage (dents in metal etc)... In general, hail is difficult to predict as there are quite a few ingoing influences and complicating factors that interfere with the course of the storm.

As @JimInSanDiego correctly summed it up: Hail is a warm weather issue, while freezing rain or ice pellets (sleet) are manifestations of cold weather.

Smaller than hailstones. Less than 5 mm in diameter.

The difference is raindrops fall but freeze before hitting the ground. Hail bounces around up in the air adding layer and layers. Sleet is a cold weather issue and hail is a warm weather issue.
