Cooling ?s

Driving around town today (~45 mph in 85* weather) my temp gauge read between 195*-200*, which is where it normally runs.

I then got onto the freeway, for about 7 miles, at 70 mph. The temp gauge climbed up to about 220*.

Got off the freeway, at my exit, and again drove 45 mph surface roads and the temp gauge returned back to its normal 195*-200* reading.

Should I be concerned?
