Snowfall in May in the State of Arkansas just doesn't happen, but that could very well change by Friday morning. John Robinson of the National Weather Service in Little Rock went in search of records of a May snowfall in the State, but could not find a report of snow later than April 30th. On April 30th 1903, a trace of snow was reported in Fayetteville and Harrison. The latest measurable snowfall was recorded on April 24th 1910 in Corning, Arkansas. As for Little Rock, the latest snowfall ever recorded was on April 19th 1983. ALL of these records are in jeopardy. Here is a look at some various computer model snowfall projections through Saturday morning.

As you can see, computer models are in agreement of a record late season snowfall across parts of Arkansas. Although measurable snowfall is not expected for Central Arkansas, a brief snow mix is not out of the question with the cold air in place. The ground is far too warm for any snow to stick though.
