Fathers Day Weekend Rainfall June 16-17

A cold front interacting with a very moist airmass brought beneficial rainfall to portions of central Illinois during the evening of June 16th.  The heaviest rain occurred along and north of a Macomb to Bloomington-Normal line...where some locations picked up in excess of 1.50!  Rainfall amounts steadily decreased further south and east, with areas south of a Paris to Shelbyville line seeing little or no rain. 

In addition to the rain, strong to severe thunderstorms impacted parts of the Illinois River Valley.  The most intense storms packed 60 to 70 mph winds and dropped ping-pong ball sized hail just south and east of Galesburg in Knox County.  The storms continued further east for awhile, producing strong winds and hail across Stark, Peoria, Tazewell, and northern Fulton counties before weakening as they approached the I-55 corridor.  Due to very weak wind shear and a loss of daytime instability, the storms continued to dissipate and completely faded away before they reached the Indiana border overnight.

The cold front eventually settled into southern Illinois and became stationary on June 17th.  Isolated thunderstorms re-developed during the late afternoon and evening in the vicinity of the front, with one cell impacting parts of Jasper and Crawford counties.  Our Robinson 7NW SWOP measured 0.41 of rainfall with that particular storm before it pushed into Indiana.
