Total rain for an area, or several added together. The dark line is what radar measured. Each forecast run starts from what had already fallen by its run time, so past runs show how they did and the newest show what is still to come.

The address of the Model Viewer and Model Multi now follows what is on screen: the layer, Areas, isobars, temperature values, split screen and the rest. Bookmark it, or save it as a shortcut, and it opens the same view at the latest run. For a quick link to one parameter, add ?param=rain (or temp, cloud, wind) to the address.
Open PrecipitationThe Cloud layer now shows white cloud over a darker map, so it stands out clearly, and you can switch between Total, High, Mid and Low cloud to see which layer of the atmosphere the cloud is in. It works on every model on the Model Viewer and Model Multi.
Open low cloud
Temperature on the Model Viewer is now drawn in 3 degree colour bands, and a new Anomaly layer shows how far each model's 2 m temperature is above or below the normal for that date and hour, against 1990 to 2019 (set to the Met Office's 1991 to 2020 averages over the UK), in blue to red bands. Turn on Show temperature values in the settings menu to print the numbers on the map. Tap Space to flip between temperature and anomaly, or hold it to peek. The Split screen switch on the bar shows temperature on the left and its anomaly on the right.
