Active Weather Pattern Next Week

The end of this week will remain quiet as high pressure builds to our north and east. We'll see highs in the low 80's the next few days, but the humidity will be low because the high will act as a block against the moisture.

As we look towards the begining of June we will see a more active weather pattern as the jet stream pattern shifts to the southeast . This will shift the flow from SW to NE, ushering in warm and moist air through nothern Illinois by Sunday. A cold front moving south and then mixing with warm moist air will create the threat of  thunderstorms will heavy rainfall through Tuesday. Because there will be a lot of energy in the atomosphere and a sharp shift in wind speed and direction in the heights of the atmosphere, there could be several large scale complex thunderstorms, or MCS's, through Wendesday.
