Local temp readings can be so subject to where exactly they are located. I can move mine 5 ft. away and get a 1 degree lower reading or higher reading.
So Newark went from 94 at 3pm to 99 at 4pm. and they are some 5 degrees and more warmer than those other recording stations. Something doesn't seem right. Maybe the 94 at 3 was a mistake. Either way they are way warmer than the other stations.
