A band of showers and storms moving through Illinois will weaken over Indiana and western Ohio later tonight but could still bring some rain and rumbles early Tuesday, as low pressure travels up a cold front into the Lower Lakes.
The complex frontal system will bring renewed showers and storms late Tuesday afternoon into the overnight. A few strong storms could develop in the afternoon, if we see breaks in the cloud cover, allowing temperatures warm well into the 70s. Another low-pressure area will move along the front from the southwest, enhancing the opportunity for embedded gusty storms.
Much cooler air will arrive behind the front Tuesday night and Wednesday, with rain tapering off. High temperatures will struggle to reach 60 degrees the remainder of the week. Another ripple wave will bring showers Thursday night and Friday, as low pressure moves off the East Coast. The flow around the storm will be quite cool, with temperatures only in the 50s later in the week.
Drier weather returns Saturday, with cool conditions in the low to mid-60s. Then another storm will arrive Saturday night and Sunday, bringing more rain and a few storms.
