It should be ok. The range is a daytime high in the high 50s, lows at or near freezing. The garage is attached, but should stay 50F or below.
One time I brewed late in the year, the weather suddenly changed to highs in the 80s despite the predictions. I was not happy with that batch. My conical is what I will use for temperature control is a cold garage, temp controller with themowrap around the conical.
