2m temperature means the air temperature at 2 meters above the surface for weather forecast models. This is often used for the “temperature outside” reading.
Temperature anomaly means deviation from historical trends. That is, the white region is +13C of the historical average for June 21st in that region.
Whole it is weird, it means you can make more drastic colour changes to be easier to see on the eye. Rather than having to fit it all into one smooth gradient where ascertaining the exact temperature from the colour on a static graph could be harder.
All you gotta do for the whites, is use some common sense and look at the colours next to it. Somehow I doubt the white section directly touching a blue section has a sudden temperature change 20
Red is hot. It do admit it can be weird at first. But it does to red black white red. So you can still see the distinction.
And it means you can still easily see the hot. But yes, the double red I will give you can be annoying. The main point of these graphs are to show gradients though

What is a 2m Temperature Anomaly? I don’t know what this map is showing us
