Shower and storm chances will be rolling back into the Tri State as early as daybreak for your Mother's Day. Unfortunately, we could be in for multiple rounds of torrential downpours and rumbles of thunder through the first half of the day. The latest timeline has a cluster of storms arriving as early as 7AM firstly impacting our western Illinois communities. This complex of storms will eventually track east and impact the metro area around 8AM before exiting east around 11AM.
The second round of storms will develop along our next inbound cold front. This additional round has the potential of producing strong-to-severe thunderstorms that could pack damaging wind gust, large-size hail & a brief spin up tornado. Through the hours of 2PM-6PM will be the greatest window for severe watches and warnings that could be issued for the area. Keep yourself weather-aware. For the rest of your Sunday, conditions will turn cooler as temperatures tumble from the 70s to the low-40s by daybreak Monday.
