We’re off to the home state of my alma mater. Anderson isn’t terribly close to West Lafayette, though, and I’ve never actually been.
At 133PM, ET, it was 85 degrees with sunny skies in Anderson. High pressure remains the dominant feature for much of the eastern half of the country, however shortwaves continued to ride the northern and northwestern flank of the the ridge, tapping into a good deal of heat and humidity.
There is very little upper level support for the ridge, and disturbances are beginning to show a greater ability to penetrate it, such as will be the case this afternoon, when some showers and storms will be able to crop up over Indiana. One issue will be the absence of a scouring flow to sweep out clouds, so even when it isn’t raining, it will likely remain cloudy. The first shortwave will move in tonight, and stall over the region, bringing about a chance for some showers through the day tomorrow, with another round moving in on Sunday with another fast moving wave. This wave will be more likely to produce thunderstorms.

There is certainly some divergent thought on this forecast. The clouds, should they develop over Anderson, will play a vital role in this forecast verification.
