August 2-4 Rainfall

As drought conditions continue to worsen across central and southeast Illinois, a few locations picked up beneficial rainfall during the first few days of August.  On August 2nd, a Mesoscale Convective Vortex (MCV) generated by a large cluster of thunderstorms across the Plains during the previous night tracked into south-central Illinois.  This feature triggered another large complex of storms...mainly impacting areas along and southwest of a Jacksonville to Shelbyville to Robinson line.  Due to copious amounts of moisture in the environment and the slow movement of the storms, some locations picked up in excess of 2 inches of rain.  In fact, an observer in Morrisonville in Christian County measured over 4 inches!  An approaching cold front brought additional showers and thunderstorms to the area on August 4th: however, the bulk of this activity slid by to the north across northern sections of Illinois and Indiana.  The heaviest rain from this system impacted northern Vermilion County, where an observer in Hoopeston recorded 3.58.  The lowest rain totals during this period occurred across the heart of central Illinois...where many areas from Fulton County east southeast to Edgar and Clark Counties received less than one quarter of an inch.
