We look at the weather sites on the internet frequently. It's just part of our job to try to get some idea as to what might be coming in terms of the weather. So, we rely on sites like Wunderground and NOAA to give us information and we hope that what we see has a certain level of accuracy.
We looked at Wunderground on November 27 of this past year and we saw this.... Do you see why I might have been a bit concerned?
If you have not seen it yet, look down in this area.
I think I would have remembered November 26 as an exceptional day if that high temperature were accurate.
