Sat weather looks ok if your in LaGrange by mid afternoon. The chance of rain gets worst and by evening we will have rain.
Sunday we are almost guaranteed rain. Bring your rain gear for Sunday. The tail wind all weekend should help. Hope to keep from being totally drenched by the finish in Austin.
I rode the MS150 the year of the wind. It was a horrible head and cross wind once you get out of Houston. That was a long day in the saddle. Once we made the left headed to the fairgrounds we had a nice short stretch of favorable winds.
