Anyone know a good source of WWII weather info? The one NOAA site I’ve found doesn’t serve up the pages they index - I have a sneaking suspicion that old Unix workstation probably went offline a decade ago.

I’m specifically looking for the weather in Koln on March 6, 1945 during one of the most famous tank duels on the late western front between a Pz V Panther and a T-26E3 Pershing. I’m considering a bit of writing on the topic.
