Yeah it is. I didn't realize what a dramatic difference there could be between high and low temperatures in a day until I moved away from the Great Lakes. All my life I'd lived within 5 miles of a giant water buffer, so our max and min temperatures were very close. Then I move here to NC and all of a sudden it was like, "The sun has set, so now all the earth will FREEZE". Ridiculous.Have you ever measured stream temps during late afternoon versus early morning. Usually it is a pretty wild swing.
Example:
Today's high temp in Cleveland, Ohio was 43 and the low was 28. That's a 15 degree difference.
Today's high temp in Winston-Salem, North Carolina was 65 and the low was 37. That's a 28 degree difference.
Edit: lol, Wednesday's high and low in Cleveland are 14 and 10. That's what I'm talking about. Wednesday in Winston Salem? 45 and 21. wow
