Severe Weather Threat Continues across Ohio Valley

The risk of severe weather this afternoon is building across Illinois, Indiana and parts of western Kentucky.
Here is a statement from SPC in there latest severe weather outlook with a map below.

"VISIBLE SATELLITE IMAGERY SHOWS BREAKS IN THE CLOUDS ACROSS CENTRAL IL IN VICINITY OF THE WARM FRONT. LOW LEVEL MOISTURE IS ALSO INCREASING FROM THE SOUTH...WHICH SHOULD LEAD TO AFTERNOON MLCAPE VALUES OF 500-1000 J/KG IN THE REGION. SCATTERED THUNDERSTORMS ARE EXPECTED TO FORM AHEAD OF THE SURFACE LOW...BOTH ALONG THE WARM FRONT AND IN THE WARM SECTOR. FORECAST SOUNDINGS SHOW STRONG EFFECTIVE SHEAR AND SUFFICIENT CAPE FOR SUPERCELL STORMS. MESOSCALE MODELS ALSO INDICATE THIS REGION IS MOST LIKELY TO SEE DISCRETE INITIATION. LOW LEVEL VERTICAL SHEAR IS MODEST BUT SUFFICIENT FOR A RISK OF ISOLATED TORNADOES...ALONG WITH HAIL AND DAMAGING WINDS AS STORMS TRACK EASTWARD INTO IND"
