The data to which I was refering is not their forecast data. It's their posted historical data. On Monday morning, November 5, at 8:00am EST when I checked, they were showing 51 as the low for 11/04, but also noted that the readings were as of 5:00pm on 11/04. About an hour later, they had revised their information to show the low of 38, and noted their inrormation was as of earlier on 11/05. It looks like Wunderground retrieved the original data, but is not retrieving the revised data.
