I heard a loud band, and looked outside to see if the world was ending. Luckily we’re good!
Went for a super foggy nighttime beach walk and somebody had written creepy messages in the sand. “Leave now” and “you’re gone” and “I kill” so to say I was slightly unnerved is an understatement.
 
Does anyone know when the updated climate normals (1991-2020) are typically released? Is it usually quickly after the new year, or does it take a few months?

A few months unfortunately, but the raw data is available on nowdata of course ! This set of normals will be the most extensive set ever . There will be multiple kinds of normals that are calculated differently ( they did that a bit for 81-10 I can share those for y’all ) , normals for offshore locations in the mid Atlantic ( hopefully southeast as well) , interpolated normals for more places that don’t have stations and more ! Probably won’t be till the spring at earliest that we see any of it.
 
@Tarheel1 vs onset ice birdman vs not in mby brick vs southeast ridge stew point Stan . Who you got? I think stewpoint Stan comes out on top when he hits everybody with the it can’t snow in March or hit 70 in November card. Could be wrong tho , onset ice birdman might hit everyone with the mega BOOM BOOM WHEN THUNDER ROARDS GO INDOORS CAD. Underdog is brick.

Brick killed a guy.
 
Based on the NOWDATA, I have calculated the *unofficial* 1991-2020 normals for RDU airport. Interestingly, the 1981-2010 normals on the NOAA website were all 0.3-0.6°F higher than on the NOWDATA website, so it is possible these normals get revised a bit upward (perhaps due to a calibration issue?)

Average high temperature by month (change from official 1981-2010 climo based on NOAA website):
  • January: 51.6°F (+0.7°F)
  • February: 55.5°F (+0.3°F)
  • March: 63.1°F (-0.3°F)
  • April: 72.5°F (+0.1°F)
  • May: 79.7°F (+0.1°F)
  • June: 87.1°F (+0.1°F)
  • July: 90.5°F (+0.3°F)
  • August: 88.4°F (no change)
  • September: 82.2°F (+0.1°F)
  • October: 72.8°F (+0.1°F)
  • November: 62.8°F (-0.8°F)
  • December: 54.5°F (+0.9°F)
Average low temperature by month (change from official 1981-2010 climo based on NOAA website):
  • January: 31.5°F (+0.5°F)
  • February: 33.8°F (no change)
  • March: 40.0°F (+0.1°F)
  • April: 48.5°F (+0.5°F)
  • May: 57.4°F (+0.9°F)
  • June: 65.7°F (-0.1°F)
  • July: 69.9°F (no change)
  • August: 68.5°F (-0.1°F)
  • September: 62.3°F (+0.6°F)
  • October: 50.0°F (+0.2°F)
  • November: 39.6°F (-1.2°F)
  • December: 34.2°F (+0.9°F)
I'll do the calculations for precipitation and snowfall later, but as you would expect in a warming climate, the majority of months' average high and low temperatures increased, with the notable exception of November (likely a result of several recent cool Novembers). Considering the finalized 1981-2010 normals increased from the raw data, it is likely that the climo high and low temperatures for all months will increase for every month except November.

You have to compare the 1991-2020 raw to 1981-2010 raw . Your comparison is raw unadjusted 1991-2020 to adjusted 1981-2010. If we do that RDU actually didn’t warm even a fraction of a degree . However comparing raw 81-10 to raw 91-20 we find the annual mean increased by .7. Here is raw 81-10 vs raw 91-20 which once final normals are published in may , will be the difference between normals 81-10 vs normals 91-20. I made a 1991-2020 box using the raw 91-20 data but with the same changes made to 81-10 to make what I think will likely be close to the final product . Will post it later

High
Jan- +1.1
Feb- +.7
March- +.2
April - +.5
May- +.5
June- +.5
July - +.9

We find that November only actually cooled by .5 degrees .
