Ambient temp drop! Help!

so it's been getting below freezing down here in Texas the past few nights and I noticed a draft near my snake rack I had a crack in my outside wall which I filled with insulation foam but the inside ambient temperature of my snake rack is still 5 10 degrees below normal with the cold spot at 70 I have to go to work tonight and will be pretty busy and don't have much money for the next two to three days. Will my snakes be ok sitting at 70 to 85 degrees for a temp gradiant for couple of days ? Thanks

How are you creating a ambient gradient with such a range in a rack? Uth does not help your ambient temps hardly at all so I do see how you are getting temps from 70-85. These sound like surface temps to me.

What's the temp in the room the rack is in dropping to at night?

You are right. Those temps are from ir gun and room temp is 75.

How are you heating and measuring temps?

Heating with flexwatt tape and zilla thermostat and measuring with a temp gun.

There is still draft near rack so room temp right by rack is 70. Will snakes be OK for day or 2?

I would either move or cover the rack.

Cover with a blanket?

Yes a blanket.

I would take the belly temp up to 90-92*F and cover the rack with a blanket as was suggested.

I have one rack that I set up last spring that ended up getting hit with some cold air from an A/C vent last summer even with the vent "closed". Until I could move it I threw a wool blanket over it and it was fine.
