December 2022 Observations

 FYI for the record, the KSAV (airport) automated temperature sensor suddenly became erroneously too warm around the start of this month and is thus supposed to be replaced within a few days per CHS. This is of extra importance now because the 1PM there is showing 85 F, which if real would mean 2 F warmer than the alltime December record of 83. In reality, it is very likely "only" in the lower 80s as it is too warm by ~3 F. The Hunter (KSVN) station's 82 is likely about what it really is. CHS NWS has human observers there. So, at some point later the official record will reflect what they record.

 As it is though, 82 would be only 1 F from tieing the alltime December record at KSAV. So, KSAV is already flirting with the 83 monthly record. Strong -PNA/La Niña ftw if you like warmth in December!

 This was posted starting on December 1st by the CHS office:

"EQUIPMENT     TEMPERATURE DATA AT THE KSAV ASOS ARE SUSPECT. PARTS ARE ON   ORDER AND WILL ARRIVE THIS WEEK. USE DATA WITH CAUTION."

It was absolutely beautiful outside today. Sunny and warm without a cloud in the sky most of the day.  Unfortunately I had to work so I couldn't fully enjoy it :(

 I'm not normally a fan of warmth, but it sure did feel good going out today in shorts. We'll have a similar opportunity tomorrow due to similar warmth with sunny skies and light westerly winds again. We may not know today's official KSAV high for a few days or longer, but I'm thinking 82+. KSVN was 82+.

Impressive! That's the warmest so late in the season by a full week! The only other day this warm in December on record back to 1878 was 79 on the first. Not a total shocker though with such a strong -PNA.

 This month the AO plummeted to just below -4. The NAO plunged to -1.95 while the PNA fell to -1.86. For all months since 1/1950, there's only one other month that had a sub -4 AO day that also had BOTH a daily PNA at least this low AND a daily NAO at least this low: December of 2010. Its AO dipped to -5.3, NAO to -2.0, and PNA to -2.1. So, a more extreme for all 3, especially the AO.
