AN UPPER LEVEL TROUGH WILL MOVE INTO THE REGION AS HIGH PRESSURE CONTINUES TO BREAK DOWN AND SHIFT FURTHER SOUTHWEST AND AWAY FROM OUR AREA.
Currently, we have ridging over Texas, but a trough over the central plains and Great Lakes area is slightly weakening the ridge and pushing it westward. However, the ridge should be able to generally hold its position, and more importantly, influence over our weather. We are running 3 to 4 degrees warmer today than yesterday, so it appears we will be finally warming into the 90s today after several days of models predicting those temperatures. With that in mind, will go with temperatures in the lower 90s again tomorrow pretty much area-wide.
