Weather Talk: Northern Hemisphere lacking snow cover in lower 48 statesA few weeks ago I noted in this space that the amount of snow cover in Siberia was well above average at the end of October. That trend continued for the first half of November not only in central Asia but also over the entire Northern Hemisphere.
As recently as 10 days ago, the amount of ground covered by snow in the Northern Hemisphere was about 750,000 square miles above average. That would be more than three times greater than the size of North Dakota, South Dakota and Minnesota combined. But during the past week, the amount of snow over the hemisphere has been equaled by the average that rises this time of year.
The one part of the hemisphere that is currently lacking snow cover is in the lower 48 states, and that will likely not be changing too much in the next week.
