Historic Rainfall Amounts and Statistics


Thanks to all those who entered the 2013 summer contest.  I'll have the entries posted this week.

The rainfall from Thursday May 30th through June 1st was historic in many locations, especially western Arkansas.  The National Weather Service office in North Little Rock posted all the stats in records in a public information station I wanted to share with you.  Thanks to those meteorologists there for compiling the numbers.
