Horace,
Wunderground has observation sites on it as many have stated, though you can't go wrong with the sites others have noted.
Also, our National Weather Service Fort Worth webpage:
NWS Fort Worth has forecasts, radar, everything on it, including observation sites with wind speed/direction (just click on the county/area your interested in on the counties map (below all the graphicasts above). We have 46 counties of responsibility (including a good chunk of North and Central TX).
Also, the MyRadar app as one gentleman stated is good for checking both radar and observations.
We also have a mobile website (works like an app, but since we're fed gov't, it's not in the app store and we can't profit off of it).
Just pull up Safari or any other phone browser, type in "mobile.weather.gov" in the address/url line at the top. Once the website shows up, put in the city or zip code (you can do this for multiple locations if you're traveling), then at the bottom, select the box symbol with the arrow pointing up, then one of your selections should be "Set to Homescreen". Our site then will produce an app-like NWS icon on your iPhone or android. It's basically our website that can be accessed on your phone.
The radar isn't as dynamic as RadarScope or MyRadar apps, but is decent and puts your location up you entered on the radar using GPS. If you don't want that on your radar screen, just click that same symbol below and it disappears.
Good luck buddy. I couldn't make it to the office this morning, as wife is flying back in, then start a long string of graveyards tonight, then off on a cruise with the family. May be late July before I'm back out there.
