A developing wave of low pressure over the Southern Plains on Wednesday will move northeastward to the Upper Great Lakes by Friday. On Wednesday, the system will produce showers and severe thunderstorms over the Central/Southern Plains. Therefore, the SPC has issued an Enhanced Risk (level 3/5) of severe thunderstorms over the Central/Southern Plains through Thursday morning. The hazards associated with these thunderstorms are frequent lightning, severe thunderstorm wind gusts, hail, and a few tornadoes. Additionally, the storms will produce heavy rain over the region. Therefore, on Wednesday, the WPC has issued a Slight Risk (level 2/4) of excessive rainfall over parts of the Middle Mississippi Valley and Central/Southern Plains.
