That's why you'll never find it.

I believe it stands for Warm Air Advection. I think it describes a situation where you have an area of low pressure pumping warmer air into the high latitudes, such as Greenland, helping to build high pressure there, and so it can be favourable for colder conditions for Western Europe, like the opposite of what we have currently. That said, I'm no expert.

Snowing lightly in Ellesmere Port. Flake-size hard to estimate, but at a guess pre-decimal. Nothing on the cars yet aside from bird faeces.
