Cold Impact to X Mileage

[X Fan]

Drove from beach to Triangle early yesterday morning on I40. Temps were in mid 40's. Don't know wind differences.

OIB to Warsaw previously (80 degrees) was: 104miles / 117RM; yesterday (46 degrees): 104miles / 136RM
Warsaw to Cary: 81miles/ 93 RM; yesterday (47 degrees) 78miles / 99 RM

Pretty big difference in Range Mile use....going to need to watch this while traveling to/from Florida in winter....
