High pressure briefly takes control of our weather for Wednesday. A more vigorous disturbance is organizing to our West and will begin spreading more clouds into our area through the day. With winds out of the Northeast, temperatures will be much cooler than yesterday, closer seasonal average highs near 80 degrees. That new wave approaches Southeast Wisconsin this evening and should begin triggering some showers through the night. Those showers and perhaps a thundershower will be scattered throughout the region on Thursday with some diminshment through the overnight hours. After the rain departs, another ridge should bring more sunshine for the work week's completion and temperatures will be noticeably cooler with highs only in the 70s for a stretch of several days.
Have a great Wednesday!
