Snow Levels in Budapest (1945)

I don't know for certain, but if the pics you have seen show no snow then thats the way i would go. Remember cities are warmer than the countryside, so unless the snow was extremly heavy, the snow would soon melt.

Could have been a warm year, too. But if you really want to convey the idea, maybe try a few small snowbanks in shadowed places, like in a back corner, And then make a brownish "slush" over the ground to look like melted snow. That would probably look good.

Alright that sounds reasonable, the heavy fighting also probably wouldn't have allowed a buildup anyways, thanks.
