After that, install a 180F thermostat b/c even if the t-stat isn't the issue, this needs to be done anyway. There's other posts on how to check and see if your radiator is clogged by Savanahbuzz...something about taking temp readings at the top and bottom of the radiator, ensuring >10F difference. Checking the fan clutch is fairly easy if you have a basis for comparison. All these things are good preventative maintenance anyway, so you're not out the time/$ if it doesn't fix the issue.

I'm in Austin so if your ever stranded or need some help with those temps let me know. I replaced my Radiator and use the 180 Stat. My temps this past week never rose above 194. It will reach 200 in the heat of the summer in bumper to bumper traffic.
