Up here in Labrador Canada we recently had it -70f. I haven't had any issues yet. Just keep the block heater plugged in over night.

 

Air temp, or windchill?

 

I live in Streetsboro also and my car sat for a few day and I havent had any issues. Heres a cool picture from our last snow storm.

 

We were in the negatives for the last 48 hours, its 20 now. Only ran into a few issues in my stock JKU. First, monday, I got stuck in about a 3'-4' drift. I was plowing along, and it just came out of no where, blended in with the rest of the snow. Following that, the rest of the day I had issues with making a hard right turn. I tried to clear all the snow out of there I could, but you can't do much in windchills under -40. I garaged it that night, and it thawed out and all was well.

The next problem sucks a little more.... I hit a large bump at a railroad crossing yesterday, and I just watched my back window on the soft top split in two. Now I need some duct tape and bailing wire.

 

It was -42 yesterday and the drifts in my driveway were 4-5' deep and my driveway is 180' long heading up hill to the road but after letting it warm up (in the garage) she plowed through it all with no problems in 4-low and I even pulled my neighbor out of a 5' ditch with unplowed roads and he was in a F-350 4X4 4-door long bed and I yanked him right out of there so I was really impressed...nothing stops a JEEP! It is a 13 RUBI with every option on 35" MTR w/Kevlar and Teraflex 3.5 lift

 

Had to have been with the windchill factored in?

 

One or to days was air temp where I work. In my town its about -60 with the wind chill

 

Yes it mostly is with the wind chill but it has been just as cold without the wind. We get 6 months of winter

 

right Ron ? Maine Newhampshire, And Vermont it usual drys out around beginning of may pending on upper or lower part of the states and we hit a few days here -25f -30 f with windchill

 

This is outside my kitchen window, no wind chill. (°F)
