Our memory of the past winter can sometimes be judged by a strong beginning to the winter, a long & cold winter season or a massive snowstorm that tested all snow removal equipment at the end of the season. While having the tremendous advantages of temporal and spatial completeness, these reconstructions: (1) are based on computer models that may have model-based errors, (2) are coarsely sampled on a 50 km grid and are therefore unable to reconstruct the local variations of many microclimates, and (3) have particular difficulty with the weather in some coastal areas, especially small islands. The charts include values for the 2021-2022 season through February 24, as well as the long-term average and the season with the highest recorded values at each location.
