PEORIA (Heart of Illinois ABC) -

UPDATE 10:30 AM: The round of early morning showers and cloud coverage is helping limit instability that is needed for the severe weather to spark this afternoon. This means, the threat for seeing severe weather is lessening, or rather staying more south. I still think a few strong gusty storms are likely in the window of 1-6 PM here in central Illinois. Storm Prediction Center will issue an update around 11:30 AM, so we’ll continue to update this story as the day progresses.

A warm, breezy, and wet start this morning. A first line of showers and storms is currently making its way through the area, so you may hear a few rumbles of thunder along with some heavy rain this morning. This same line of storms worked through Iowa late last night, but as it approaches central IL, it began to decay and break apart. Any associated storms are not expected to be severe, but may be strong and gusty. Temperatures will remain warm climbing into the low 70s today, and winds will continue to be breezy with gusts up to 30 mph.

A lull in the rain shower and storm activity is anticipated between 10 and noon. We are continuing to keep an eye on how long this first round of showers and storms last. If it continues into late morning, this could help delay and deteriorate our potential for severe weather in the afternoon.

Otherwise, once the cold front moves in we expect the second round of showers and storms to begin after noon. Daytime heating will likely provide more energy to spark these new storms, in which some have the potential to become severe. Areas east of the IL river have the best chances to see these storms develop and become severe.

The main threats with these storms will be the damaging winds that may gusts up to 60-70 mph, large hail up to an inch and a half, a few possible tornadoes, and some flooding.

Primary concern: damaging winds up to 60-70 mph.

Cold air behind the front looks to work in this evening, this will help limit our chances for any lingering storms to become severe. The showers and storms look to come to an end before midnight, and skies look to gradual clear heading into the overnight. Cold air will quickly set in as temperatures will drop into the mid 30s overnight. Winds will continue to be breezy heading into Thursday, skies will be sunny, and highs only in the mid 50s.
