A shortwave diving southward on the east side of an upper ridge led to scattered thunderstorm development on the evening of the fourth across southeastern Kansas into the Oklahoma Panhandle. This activity congealed into a line of storms that moved south through the western Texas Panhandle and across the western South Plains producing isolated strong to damaging wind gusts. The Parmer County Sheriff's department reported that a carport was blown into powerlines due to strong winds.  A little farther south a Texas Tech University West Texas mesonet site near Morton measured a wind gust to 59 mph. Additional thunderstorms developed around sunrise near an outflow boundary across Swisher County which produced one additional severe wind gust to 60 mph per the Texas Tech University West Texas mesonet site near Vigo Park.

A slow-moving cold front draped across north-central Illinois triggered scattered thunderstorms during the afternoon and evening of July 7th.  While severe weather and flash flooding were not observed, locally heavy rainfall within the storms created hazardous driving conditions.  As a result, a vehicle skidded off the northbound lane of I-55 near Lincoln in Logan County and was struck by a semi travelling in the southbound lane at about 10:11pm CDT.  Four of the five passengers in the vehicle were killed, while the other passenger sustained critical injuries.

A warm and unstable air mass was found across the Ohio Valley that stretched northeastward along Lake Erie and ahead of a surface cold front and mid-level shortwave trough. CAPE values were 1000 to 1200 J/kg, and bulk shear values were 35-40 knots. Storms from Ohio expanded northeast into our region through the early evening hours. A few cells became stronger over the lake and one in particular started to show deep rotation as it moved down the New York/Pennsylvania border.
