Ross is your weather gadget working right? I'm showing 80 for Tues and Weds all the other days are in the 60's. I live on the other side of the Delaware river in NJ not far from you.
Questioning the quality of the Winstep's weather gadget info, heh?
Weather gadget shows the same I got from NBC news. They're calling for high humidity like a return to summer.
If you look at the weather feed source in that balloon tooltip you will notice it says NOAA/Weather.com. This means current weather conditions are being retrieved from the NOAA's METAR feed and forecast conditions from Weather.com. This is possible because the location Ross is using has both a METAR and a Weather.com code.
METAR (METeorological Aerodrome Reports) is used by civil aviation and reported almost in real time by airports all over the world. A METAR weather report is predominantly used by pilots in fulfillment of a part of a pre-flight weather briefing, and by meteorologists, who use aggregated METAR information to assist in weather forecasting - so it has VERY detailed and accurate weather information for current weather conditions at that particular airport and surrounding area.
The forecast is already responsibility of Weather.com, since METAR only provides current weather conditions. Provided Ross did not change that location's Weather.com code in the settings, it should be pretty accurate too.
If any of the feeds fail for some reason, the Winstep weather gadget still has the MSN and Yahoo weather feeds to fall back on.
