It's only the first week of October, but in the far North of the continent, and on the high peaks of the Rockies, snow and ice have begun to reappear. As the weeks roll on, the extent of that snow and ice cover will gradually spread south, and descend in altitude from the mountain peaks.
None of which is news, of course. But it's cool to watch it unfold. Here is a link to an animation assembled from 31 days of data - through most of September and into this week - gathered by the National Oceanic and Atmospheric Administration. Go back to it every few weeks and watch the snow and ice get closer to Maryland.
Here's another view centered on Alaska and the Arctic Ocean, including much of Siberia. It's already pretty snowy there, too. Monday - Oct. 9 - is the date of the earliest recorded snowfall in Baltimore.
