Yeah, I believe the reason for the new watch is that a dry slot has moved in and allowed for some good diurnal heating. Temps now in the low 60's and dewpoints around 50-53F (a report of 55F in Fort Wayne), so instability is building just a bit. I live here in southeast MI, in Rochester Hills, or about 15 miles east of DTX. I wouldn't get too excited here in the DTX area, storms already look rather weak, and with loss of daytime heating, that will only make it worse. Now Thursday is something to look at, synoptic setup very similar to April 3 1974...Check out the latest GFS runs and compare it with the April 3 1974 archive maps here http://www.weathergraphics.com/sfcupr/.
