Look Up Records and Map Them.
What a great site for anyone interested in looking up record temperatures, precipitation amounts and snowfall amounts. This program at NCDC allows you to choose the time frame, the variable, and the location and the records are then mapped for you.
The map to the left shows the record high temperatures on March 12, 2012 produced at this site. Be patient when accessing the site, it loads slowly.
