Oppressive Humidity

The image to the left is a snapshot of the dew points across the country as of 11am. Dew points right now are hovering around 70 degrees. The cool front that sparked last night's showers is currently extending from Milwaukee to Rockford to the Quad Cities. The strange thing that is occuring is how far the lag extends between the cool front and the drier air. It is still very muggy as far as 250 miles away. Dew points are still as high as 65 degrees back into northern Wisconsin and southern Minnesota. Typically the drier air is about half that distance away.

What this means is that we will have to deal with the steamy conditions at least into this evening. Also, because there is so much water vapor still in the atmosphere an isolated shower or two cannot be ruled out this afternoon. -ADAM
