Diesel & Gelling

I have 3 six gallon plastic cans of diesel for my tractor. Didn't think about that until today. Its sitting under a shed with 3 sides. It got to the teens 2 or 3 nights recently. Actually to 12 one night. Its finally gotten to 45 this morning.
I took the cap off of one of the cans & kinda shook the can & the diesel looks fine, no sign of gelling. But, I dont know if it did gel during the freeze. As far as I know about diesel in an engine, the gelling issue is that it gells in the lines & injectors & filters, etc.
Just FYI, I did put antigel in the tractor but not in my cans in storage. As far as I know, once it gets above freezing, it should be ok... right? Or is there a problem now with the diesel even after it gets warm?

(side note) It'll be 70 degrees by the weekend here.

Gelling is solely a result of temperature making the fuel too thick to flow. When it warms the problem goes away. It is OK to use fuel that has gelled and warmed and returned to liquid.
