July 8 Rainfall

A cold front dropped into southern Illinois on Sunday, July 8th...bringing relief from over a week of oppressive heat that routinely featured afternoon high temperatures at or above 100 degrees.  Despite providing the cooler temperatures, the front did little to alleviate the ongoing drought across Illinois.  While most areas received little or no rainfall, a few spots managed to pick up significant amounts.  A narrow band of elevated thunderstorms formed well north of the front along a Gibson City...to Clinton...to Athens line.  Measured totals in this corridor ranged from 0.50 to nearly 1.50.  Some second-hand reports indicated that as much as 2 to 3 inches may have fallen over northern DeWitt County between Heyworth and Wapella!  Further southeast, scattered strong thunderstorms developed south of I-70 during the afternoon.  A few of the storms produced damaging wind gusts, resulting in trees and power lines down in northwest Lawrence County around Chauncey, as well as across southern Jasper County just south and east of Newton.  In addition, locally heavy rainfall with the storms brought 1.37 to Lawrenceville.

NOTE:
In order to form a more complete picture of the actual rainfall across the area, included are additional reports from the Cooperative Weather Observation Program (COOP) and the Community Collaborative Rain, Hail, and Snow (CoCoRaHS) network.  Those sites are annotated in RED on the accompanying table below. 

Also below is an image showing Doppler Radar rainfall estimates from Sunday.  From this picture, you can see that heavier amounts may have occurred away from our observation networks, especially over far southern Lawrence County where the radar is showing over 6 inches!  This is likely an over-estimate due to hail within the storm: however, we have no ground truth available in that area to confirm it.
