Storms out west could move through northern Illinois Thursday night
9:45pm Update: Thunderstorms with frequent lightning moving in from the west from Monroe to Lanark. Small hail and a few stronger wind gusts are possible, but overall severe threat remains low.
9:10pm Update: Severe thunderstorms continue to move into northeast Iowa, but are moving more southeast than east. This is where better instability is located. Storms a bit further north will still pose a hail threat as they become elevated, but overall severe threat for northern Illinois and southern Wisconsin will remain low.
Despite a cold front passing Thursday afternoon, high temperatures still made it into the upper 80's and low 90's. It wasn't as humid, but it was still very hot!
With the front to the south the majority of the afternoon and evening will be very quiet. Big thunderstorms are developing over the central Plains, closer tied to an area of low pressure. But thunderstorms developing over northeast Iowa bare some watching as they are likely to move into northern Illinois after 9pm tonight.
Additional thunderstorms - some likely severe - are possible going into the weekend. I'll have more on that coming up in a later post.
