Strictly speaking, the political discussions are to be left at the door in the Chaser Bar & Grill forum.
I agree that "tornado alley" states (which are also mainly agricultural) could easily find the political will to build mesonets. Basically, the just need a team of nerds to connect the weather stations already in place into a nice web interface. In Nebraska, the State Dept. of Roads already maintains a healthy number of weather stations all over the place, and if there was a way to get stations in other cities/towns on board (fire stations, schools, etc.) we could have much higher resolution information than we do now. Stage 2 would be filling in the "holes" with additional stations.
They aren't going to do this for a "fringe group" like chasers, obviously, but giving it an agricultural slant would get a lot of the population behind it, and the public safety aspects make it easily sell-able to the public also.
Iowa has done this with Iowa St. taking the lead, but naturally they have a good meteorological program (ditto with OK). That seems to be the core unit that drives these things.
I think if someone could create a partnership between state universities, state government, and get the support of the State's NWS offices/personnel, we'd see this happen (once the economy comes out of this funk, anyway. I doubt
any new initiatives have a lot of hope in the current environment.)
