That's very helpful. Thanks

The temperature in the ground probably wouldn't vary that much, except it's under concrete, which can make a big difference. The other thing is, how long ago was the gas put into the ground from the truck, as the gas could have been a much higher temperature in the truck. So it seems to me that the the early morning is the best time to get gas, after an overcast the previous day, and as long as possible since the ground was filled from the truck.
