Double significance of 70

You know it's a cold winter day in Florida ...

When daytime highs don't break above 70° F.

The above graph shows high and low air temperatures
for Naples Florida.  Gray color coding in back shows the
historical daily averages and extemes.
On the flip side,

Nighttime low temperatures regularly rising above 70° F is when the regular pattern of afternoon rainfall begin.


Interesting to see the same number usher in two seasons, both summer and winter.
