Factual error: Mr. Monk is crossing off days on a calendar until Trudy's passing anniversary. Three days before, he says "only two days left." Mr. Monk is too much of a perfectionist to say that. How did this happen?
Factual error: The storm chasers are meeting by the road and you see the sign for I-90 East in the background several times. This movie takes place in and around Texas, yet the route that I-90 takes is nowhere remotely close to that far south.

[This also falls under "plot hole" and "character" mistakes.] (00:07:45 - 00:08:40)
