Over the weekend we experienced a pretty big cool down for the midwest. We saw temperatures in the 70's and high 60's on friday and saturday, while on sunday we saw temperatures plummet into the mid 40's and its supposed to remain in the 40's for most of the week. We saw one cold front push throughout the area over the weekend and now we have another one coming down from Canada into Wisconsin.
This is a photo of the current surface radar for the midwest. You can see on the east side of Ohio of the first cold front that moved through the area on sunday. Combine that cold front with the low pressure system, we experienced precipitation. We now see another cold front moving into the area from the north. To the west there is a stationary front followed by a high pressure system. 

This photo is of the wind direction and speed for the U.S. You can see over lake Michigan how the wind is swirling in a counter clockwise direction, this is due to the low pressure system that is over that area. You can see over Minnesota and Wisconsin how wind speeds are around 20 mph due to the jet stream dipping into the states in this areas. 

You can see from the upper air sounding from Minneapolis that we do have a chance of rain based off of the LI index. Also to note, the start of the troposphere is relatively low around 10,000 meters. 

This final diagram is of the future forecast for the next few days for the midwest. You can see how the jet stream has dipped relatively low down to the south of Illinois. This allows for the wave of cool air we are experiencing throughout the area from the north. On top of it all there is a low pressure system that is producing precipitation along with the cool temperatures.
