I doubt it. I'd think the dissipation of heat from lightning occurs logarithmically. Most of it is dissipated quickly.

It's probably similar to the temp being warmer on a night with a full moon than one with a new moon. Theoretically it would be different, but it's practically impossible to measure.

I don't think the moon's heating effects are significant enough to have any effect. Could be wrong, though.

Yeah, there's pretty much no difference at all. But theoretically it's possible.

I also wonder whether diurnal range is lower on nights when radiation fog forms. You would think that the fog would prevent the temp dropping any lower since the air is kept in, just as a cloud would do the same.

I think it's the opposite. Doesn't radiation fog occur on night where the temperature drops quickly to the dew point? It could be indicative of fast cooling rather than high diurnal range though. Or indicative of a slight inversion.

Yeah, it generally forms on calm, clear nights. But after it forms in the early morning hours, I suspect it would prevent the temperature dropping further.

Here we don't get them very often and they still suck Lol.

That lightning was incredible, constant CG for probably 2 hours. I'll never forget how heavy the air felt beforehand.

Perhaps, but oftentimes the fog doesn't form until about 7 AM which is the coolest part of the night/morning.


I remember when I lived in North GA days with the highest diurnal ranges would more often than not start off with some radiation fog, though it would obviously form more in low lying areas.

Air is quite heavy here right now as well. 77 F dewpoint after the rain.

Only 23 days of the month and plenty of heat records destroyed.

Days with max temp >= 94 F: 9 (old record 7)
95 F: 6 (old record 3)
96 F: 4 (old record 2)

Avg max temp is 92.6 F so far, much higher than the previous highest of 91.3 in 2010.

How typical. Good storms passed to my north and west, and moving in a NE direction. The only thing moving in this direction is some drizzly bull****.
