Thaws are not very often at the Brocken thats true- and if there is a thaw the dewpoint is usually low. I have been over the past weekend to the Harz and visited the Brocken on Saturday when it was about 5-7°C on the summit, but the Humidity was only about 30-40%. Not the typical Harz winter wonderland i expected, but it was still pretty nice and with the sunshine and calm wind it even felt very warm, in the end i even took my jacket off since it was too warm.
Of course due to the warm days the trees were mostly snowless (except for the northern sides of the mountains), but the foot paths were still completely covered with a white blanked and also most skiing trails were open.
Snowcover was about 20-30 cm in the Upper Harz regions (Torfhaus/Braunlage) and 94 cm on the summit.

I'd imagine the record high is about 25, though there will have certainly been some years fail to top 20. I spent a few days in the Lake District during the very hot summer of 1995, and measured temperatures of 23 at 800-900m. That was an unusually hot summer though, many of our heatwaves dont reach that far northwest.
Looking at that data you can understand how no trees grow above about 500-600m in Britain. The Winters up there are no colder than in central Europe, but the summers are Arctic.
