US snow cover shrinks under high pressure

Look at this map of the US snow cover. 

Now scroll down and look at it just a few days ago.

It melts quick this time of year.  The sun angle is much higher than it was earlier in the winter. Also - a large ridge of high pressure has built into the center of the country allowing temperatures to finally warm up to seasonal - and in many cases - above seasonal levels.

I can't wait to post the map later this coming week - I bet most of the southern states will be clear of snow - and the depth across the nothern tier of states will be a little less pink and more in the darker blues.
