Re Kursk and Hitlers folly?
Blitzkrieg re quired close air support of attacking ground units as well as air support attritting local logistics and communications. The standard Whermacht operandi required good weather!
Read Battle of France, Barbarossa, Various Battles leading upto Stalingrad, Kursk and plenty of others on the Allies side once the importance of combined air and ground assault was taken to the level that the Germans ahd developed in 1940.
It's Bulge which is the exception. The LW is decimated and there is a last ditch hope to cut thru the Ardennes forest, break out thru the Belgium plain and achieve Antwerp to cut Montgomery off in Holland. The fog was a bonus.
