I checked the wind and temperature info on the Windfinder site for Granbury. It is as close as I can get to Wheeler Branch. It looks like temps beginning arund 59 degrees and climbing but only to around 80 or so.
Winds in the 7 to 8 MPH early but rising to 12 MPH with gusts to 17 I believe it said. Wheeler is always windy since it is up pretty high. Winds will be out of the south a bit but mainly east.
We'll see how it goes. It might take some hiding out in some areas to sort of stay of out the wind if it gets gusty.
I'll likely be there before 7AM and start setting up.
