Hoping we don't make it up to 80 in Burlington this afternoon, NWS has the triad at 83 today, although, I have noticed that there has been much more cloud cover to verify across NC.

HRRR 9:00 initialization which makes it to 82
The NWS does actually mention this in their forecast discussion,
"With the mid-morning update, made some minimal changes to the hourly
temperatures, but also bumped up cloud cover with pretty widespread
cloud cover moving in from the west."
However, they are not too encouraged that this will make any difference in our temperatures,
"A band of mid and high clouds within the mid-upr ridge axis will
move across cntl NC today, but with partial sunshine that should
contribute to warm sector warming into 80-85 degree in most areas."
Even though this is being very optimistic, this is something that I just want to point out seeing in now-casting. If this forecast were to bust, I would think it would do so on the low side more-so than on the high side.
Edit: At least Orange County/Hillsboro west, RDU up to 77 GSO at 64
