Amen to that
. So happy you appreciate my efforts, I'm very pleased to keep up monitoring and sharing the results.
To keep on sharing, I also forgot: this is looking like it will be special spot Charleston Airport's first entirely good monitoring season (read: their best monitoring season) EVER. The 6 criteria for a Southeast US place to have an entirely good monitoring season (defined as October-April and primarily November-March) are:
1) All months must be at least around average if not above average.
2) The frost-free season must last until at least December and begin no later than the end of February.
3) Once the matter of the frost-free season is settled, all months must have cold extremes around the usual coldest if not warmer than usual.
4) Likewise, with heat monitoring being just as important as cold/frost monitoring, all months must have heat extremes at the usual hottest if not warmer than usual.
5) There must be wild temperature fluctuations between the heat and cold for that Southeast US flavor.
6) Last but not least, rainfall must be around or above normal so there is no drought (not every month has to be at or above normal however, a dry month can be fixed with a wetter one down the line).
For Charleston Airport this season:
1) October-March have ranged from 0.2C to 3C above average, running 1.3C above average and April is looking to continue that trend from the Climate Prediction Center. Check.
2) First frost December 12, last frost February 20 - and even a bonus month-long frost free period between January 22 and February 20. Check.
3) October-March have ranged from getting exactly normal cold extremes to +5C above normal cold extremes, with their total being cold extremes 0.8C above usual and a usual winter minimum 2C above usual. Climate Prediction Center again points to April following this, so check.
4) October-March have ranged from getting exactly normal heat extremes to +3C above normal heat (even tying an all time record high for January), with their total being heat extremes 1C above usual. April, again, is pointed to following this, so check.
5) The following 10 day stretch in Charleston Airport's January 2024 is a serious contender for the best wild temperature swing monitoring I have ever done!
1/19: 18/3C
1/20: 7/-3C
1/21: 7/-5C (coldest day of the month and season)
1/22: 16/-5C
1/23: 19/10C
1/24: 25/17C
1/25: 26/17C
1/26: 28/17C (warmest day of the month and tying the all time record high for the month)
1/27: 26/16C
1/28: 21/10C
Notice how the hottest and coldest days were only 5 days apart, and how in a mere 3 days it went from an average January day in Wichita to an average January day in the Florida Keys.
6) Even if April gets no rain at all, the October-March rainfall total is 31mm higher than the average October-April rainfall total, so check.
Incredibly satisfying for a cold hole I initially totally disregarded in favor of the right-on-the-coast-downtown station to be lavishing me with better performance than I could ever expect!
