High pressure will keep its grip this afternoon as showers and storms remain out west across Iowa and Missouri. One storm complex formed across the northern Plains overnight while another developed in north-central Missouri early this morning. The storms were fed by the low level jet, higher dew points and high temperatures thanks to a southerly wind. The second graphic on the left shows the wind direction, temperatures and dew points at 850mb, roughly 5,000 ft above. The tightly spaced green lines indicate where there is moisture convergence occurring. It's important to look at this because it gives us a good indication of where storms will typically move.
For us, our wind direction remains from the east/northeast and will continue to feed dry air across northern Illinois and southern Wisconsin. The storms will slide to the southwest of the immediate Stateline and all we should see are just a few clouds later this afternoon.
