Cloud Cover

Today and tomorrows temperatures will depend on many things but one of which is cloud cover. This time of the year it is pretty difficult to determine cloud cover for a few reasons; an excess in low level moisture due to snow cover, a large inversion layer, and over mixing of the atmosphere. Well, here are a couple of the models we can look at to determine cloud cover. These pictures are from two different models that simulate cloud cover for noon tomorrow.Its pretty easy to see that the pictures are quite a bit different. This time of the year, the models will typically over do the clouds a bit so we can expect at least a little sunshine here and there on your Wednesday but don't expect a sunny day.
