78 going to 34

New Alaska plane and the pilot comes on over the PA just before we are to depart Miami today..."Good Morning ladies and gentlemen, welcome aboard Alaska Flight 17 with service to Seattle. Our Flying time is 5 hours and 50 minutes where the current temperature in Seattle is 34 degrees." (zoom forward 3 hours in route) - "Hello again from the flight deck, we are about 1500 miles from Seattle, where the temperature is...uh...still 34 degrees." Its odd going from 78 degrees to 34 degrees in just 6 hours. It must put the body in some kind of shock. Any how...great flight, fast, smooth and quiet (just like my men - kidding).
