Pattern Dry July 2024

This has been going on for some time. Apparently, a calibration from last year didn't work.

This article was from last year (have to be a Spectrum customer to read it):

Why has the Raleigh-Durham airport been so hot this week?​

By Meteorologist Lee Ringer Raleigh

There is no doubt that this first week of September has been hot across North Carolina.
However, most days this week, the official weather reporting site for the Triangle area stuck out like a sore thumb on the statewide temperature map.

What You Need To Know

  • The high was 102 at the Raleigh-Durham Airport Wednesday and Thursday
  • Most other sites in central North Carolina reported highs in the mid and upper 90s
  • The drier clay soil around RDU has likely been a large factor in the airport thermometer running hotter than other locations this week


The Raleigh-Durham airport's afternoon temperature has been hotter than pretty much anywhere else in North Carolina every day this week.

Wednesday and Thursday's high of 102 were the hottest days this year in the Raleigh area.
Compare that to temperatures at the Fayetteville airport, which often is one of the hottest spots in the state.

The National Weather Service in Raleigh has confirmed that the temperature sensor at RDU has recently been calibrated, and they are confident that it providing accurate readings. Other nearby thermometers have been just as hot.
In the last four weeks, areas around RDU have seen less than an inch of rain. During the same time, other communities around Raleigh have measured over four inches.
The drier clay soil around the airport has been heating up like a parking lot and is likely a big factor why RDU has been hotter than other weather reporting sites, even in Durham and Raleigh.
Regardless of just how hot your thermometer read this week, this weekend and next week should not be as hot across the state.
Localized dry clay soil magically around the sensor. Lol k
 
I have a a suspicion GSP hits 100 or more today. That is above the forecast (97) but it was already at 93 as of 11am, and we already saw a noticeable bust yesterday. I think the drying of the area is catching up with us; GSP pretty much has to be in dry/drought conditions to hit the century mark.
 
At my house close to the research station for NCSU near Lake Wheeler the high today was 97 degrees. I can not for the life of me see why the National Weather Service accepts the temperature readings at KRDU when they consistently run three to five degrees above nearby stations and are now the warmest in the state on many days.
You know why. If they used every station that reported there wouldn't be the amount of increase they claim.

This is KATL yesterday:
The temp goes from 93 to 97 in ten minutes, 97 to 93 in five minutes, then stays at 93.
It does this during a certain period during the afternoon, obviously caused by direct sunlight. Its baffling that the professionals at the national weather service believe this. It was obviously 93, possibly 94 through this entire period.

This is roughly the same period for my tempest, notice there aren't 3 or 4 degree jumps in five minutes.
