Eastern Wisconsin, North Illinois in Severe Risk Today

Eastern Wisconsin, North Illinois and the northern section of Michigan are within the realm of severe weather potential for today, as a cold front is expected to sweep through the area and provoke strong to potentially severe thunderstorms. Hail and damaging winds will be the main threats.

The Rapid Refresh (RAP) model is showing several clusters of showers and storms in Illinois, Missouri around the 5:00 hour (PM, CDT) tonight. Looking over instability values, these showers and storms should be supported fairly by 1000-2000 j/kg of CAPE. It should be noted that the HRRR, which is the High Resolution Rapid Refresh, has been increasing shower and thunderstorm coverage in the timeframe mentioned above.
