Gil Wunderground.com, as do most such sources, use publicly available reporting stations. Hence, the accuracy, or lack thereof, lies at the source rather than the distributor. If I had to guess, you are likely, in this case, picking up some observer rather than an official NWS or airport reporting station. This is the equivalent of driving by the local Walgreens or CVS, looking at their thermometer, and then judging the outside temperature by that. If it seems wrong, it likely is. Reporting equipment must be properly installed and placed; and such equipment, in these kinds of instances, may or may not be. However, the problem is not with Wunderground but rather with the reporting source which may be used by many services.
Drinking beer is easy. Trashing your hotel room is easy. But being a Christian, that's a tough call. That's rebellion. -- Alice Cooper, legendary shock rocker, on now being a Christian
