With the heat wave sweeping the nation, I started to wonder if thermals are effective. I live in the high desert of CO. The temps for the last 10 days has been 97-102 degrees Fahrenheit. Will thermal work for me at this time of year, or will I have to wait until midnight or after until things cool down to use it? I'm worried that with it being so hot, everything will show as hot ie everything will look like a big white blob if in white hot mode.
