The default color map for the Prob Severe (the blue/pink) is not useful or intuitive for a quick glance. I set off to find something more representative and clicked on one at random, the NCWF Convective Grid. The color bar is divided up into four colors: green (0-30%), yellow (30-60%), orange (60-80%) and red (80-100%), respectively as % probability increases.

I found this quite good for a quick glance to see which areas have the greatest potential for severe development. The “traffic light” color scheme is very intuitive for threat levels, so it works well for this product.

Note to self: when viewing the Prob Severe with a visible satellite image, time match to the Prob Severe since it updates more often.
