So, for you, this record will have an asterisk beside it, well besides the normal asterisk that records have....

A momentary 4 degree spike to take out a record definitely gets an asterisk! But I will accept* it.

In this afternoon's case, what I think is happening here is as the mixed layer deepens w/ the heating of the day, drier air is being drawn from aloft towards the surface. This leads to lower dewpoints and some evaporative cooling that cools the surface temperature at least temporarily and enough s.t. it's detected by the sensor.

When you couple the above w/ all of the other aforementioned sources of variability in the temperature plus the inherent error in the measurements actually being collected by the sensor (this temperature sensor usually consists of a platinum resistance thermistor which is itself imperfect and exhibits non-linear variations in conductivity wrt temperature), it's not too surprising to see variations of 2-3F like this.

what a front on the GFS/CMC late next week, there is snow in Kansas!

waiting to see if the Euro shows it

From one extreme to the other. That pendulum has to swing back hard the other way to average things out.
 
I've observed numerous quick ~3 degree ups and downs on many mostly sunny afternoons on my thermometers in ATL and SAV over the years. I was initially surprised because it seemed counterintuitive to me, but now I know it is normal that even on a sunny day temps don't rise on a smooth slope.

Meanwhile, KATL has already had 8 different 5 minute obs with 97 going back to 1:25 PM including the latest ob, which has clear skies! This 97 is already enough for the highest on record in Oct, breaking yesterday's 96. 98 and perhaps 99 may not be far behind! Very special times for wx weenies! Despite GW, we may not have this opportunity (extreme very late heat in the SE US) again the rest of our lives...so enjoy it!

Yeah now that's cold. The highs are nice too.

Add 10-15 degrees to those, and we will see if anything changed since last winter! ☹️

How do you get 100 with an Early March sun angle ?

The oceans are near their climatological maximum temps at this time of the year. A south-southwest wind moving over a body of water w/ temps in the mid 80s makes a big difference in early oct vs March when they may be in the 50s or 60s.
