Since Cold doesn't really effect air operations, I thought it better to eliminate the snowflake pattern for cold.
The ground graphic still shows ground snow.

This shows that it is snowing east/north of Danzig. There is a clear hex (frost? frozen mud?) to the south east, there is light snow west of Danzig and it is cold skies to the west.
It always bothered me when trying to find what to bomb as the allies...This way I can easily see the skies are clear and not cloudy with snow clouds.
