There is no easy answer as it depends on how much sunlight you have, and your cabin temperature setting. If you use range mode, cabin heating will add at most 50 Wh/mi @ 65 mph. This might not be enough to keep you warm at -17 C, though. I am also concerned about the 15 to 20 mph headwinds you will face. Bottom line, I think, is that you will make it there provided you adjust your speed to ensure predicted range based on average over past 15 miles remains more than distance to go.
Charging at 30 A 110 V is going to be an issue. That's only 3 kW. The battery heater will use all of that overnight while trying to charge (forecast low for Sunday night is -26 C / -8 F). You will need to plug in immediately upon arriving to try to get as much charging done as possible before the battery cools down. You will probably need at least 40 hours to charge.
Good luck!
