87 here with only 45% humidity!
It was 37 degrees this morning here in GA. Grouchy, you'll probably get some cooler weather today.
If it's just a shallow well with a centrifugal pump at the surface then it should have a check valve at the bottom of the pipe in the well or maybe a few feet off the bottom of the pipe in the well.If it's a submergible pump in the well then it shouldn't lose it's prime.The pump body should always be in water.Another thing to think about.If it is only 8 to 12 foot deep,and you haven't had any rain in a while,the thing may be dry or have really limited entry to the well bore.It would act like it's losing it's prime if it ran out of water and got air.
