That is something you need to fix asap. As in go and spend 12 bucks today or tomorrow if its night for you on a thermometer. I would NOT wait until Tuesday.
I suggest you read this thread:

Just how uvb is extremely important to a dragons health, so is temperature equally or arguably more important.
Currently your thermometer is only reading the air temp up against the glass much closer to the heat of the bulb than your basking spot. Not only is this a useless measurement since you need a surface temp and these types of thermometers don't provide that, but they have been proven to be significantly inaccurate. 20 degrees off isn't a rare situation.
Especially with your basking bulb not having a dome reflector around it, and your reading of 105 so far above the baking spot, I am willing to bet your temperature at your baking surface is much too low.
Realize that if a dragon can't get its body temperature at least into the 95 degree range, metabolic function is severely limited. That means severely limited digestion. No nutrients being absorbed. That uvb?.... not doing much when the body isn't receptive to absorbing nutrients.
So do you see why it's imperative that you go out and buy an ir gun or a digital with probe end? They are so cheap now a days.
That was the first thing I thought of when I saw pics of him. He looks like my dragons do when they wake up in the morning cold.
So im going to go against the grain on this one and suggest potentially holding off on force feeding until we can confirm whether or not your temps are in a suitable range. No need to stress your dragon more by force feeding slurry when potentially all you need to do is provide proper temperatures.
