Looks really cold. We have been in the single digits and have about 6-8" of snow and ice accululation from the weekend. The wind is blowing really hard outside. BTW, woke up today and it was 6 degrees outside but my attached shed that I insulated stayed at 34 degrees. I guess the thermostatically contolled space heater is doing its job. If the shed door wasn't buried under a drift I would go and check. Stay warm!

The shed door buried, yup i hate when that happens if i need something out of there, this year i put some potting soil in garage just in case i needed it. Your shed temps are doing great in this type of weather!

I did the same, I have some of my supplies in my basement so I don't need to dig out the shed yet. Hopefully when its time to put the Christmas decorations away, the snow will be gone - I hope (unlikely).

I find that a Min/Max thermometer is more beneficial to me.
That way I make sure to catch/register the minimum temperature,
specially in inclement weather when I cannot get to the garage.
For the last 2 years, it never registered below 20*F; so I know
that my setup is OK (knock-on-wood;  I had no winter fig damage).
My garage has a small electric heater set-up to kick-in at 32*F.

It got cold here the night before last too 21*
 
We have covered our baby in-ground plants with baby blanky's
and 15 Gal tubs, now we are having 60-70* weather, that is subject to change any minute! Tx. weather.....go figure ;-) We had to uncover them.
