A while back someone posted this link that shows rainfall totals for a 1-3 day period nationwide.  I have been using it and have found it to be pretty accurate.  It shows a nationwide overview and then you can zoom in on specific areas.  It seems to me it is a good way to get a reasonable feel for the amount of rain folks are getting nationwide to make a decent estimate as to what is really happening with the moisture situation.  Anyone else using it?
