But if they arrive earlier there will be more of them...can’t win for losin’!
The extreme heat one finds in Death Valley, California or in parts of Arizona (days with temperatures up to 120 degrees) are brought about because these areas do not have any cloud cover -- just dry parts of the country.
No cloud cover means the heat of the sun is the on position, in a sense.
So once we start having warmer days, we may observe more clouds, and the sun's faucet to produce heat is a reduced position.
In my theory, having warmer days first produces cloud cover which in turn reduces some of the heating of the sun.
