May 2005 - Review of Weather Including  Temperatures and Precipitation for the Quad State Region.

Weather Summary for May 2005

May was much cooler and drier than usual.  While the weather pattern was very active for May, the moisture was lacking.

At Paducah, only 0.82 inches of rain was recorded at Barkley Regional Airport and was the second driest May since 1949.  Rainfall was 2 to 4 inches below normal across the quad state.  For the month, average temperatures ranged from 1 degree below normal to 2 degrees above normal (63 to 66 degrees). 

High pressure was firmly in control of the surface features at the beginning of May.  As this high moved east, an area of low pressure dropped south into the Northern Plains.  A cold front approached the region on the 9th producing a few showers.  Most of the rainfall averaged around one-quarter of an inch or less.  This front never made it through the area, instead, becoming stationary just north of the quad state.  A secondary, stronger area of low pressure developed along the front initiating showers and thunderstorms.  Some of these storms passed over the same areas creating areas of standing water and full ditches. 

During the last half of the month, several fronts moved across the region.  The first passed south of the region between the 19th and 20th producing showers and a few isolated thunderstorms.  Rain amounts were highly variable ranging from a trace up to 1 inch.  Training of some storms occurred in west Kentucky mainly east of the Land Between the Lakes. Another front passed through around the 22nd spawning showers that produced very little in the way of rainfall; generally less than one-tenth of an inch.  The final front of the month passed north of the region but produced a few showers north of a line from Carbondale, Illinois to Owensboro, Kentucky.  Rain amounts were light and less than one-quarter of an inch.
