Working new job for 4 days and got an interview at a better one. What should I tell them why im going to be out.

I have been working a 2 to 4 month contract job sinceast Tuesday. Unemployed for 2 months and its what I could get at the time to get some pay. 2 months applying and crickets. Since I got this short term job others have been coming in for interviews.

I have 1 this Monday 10/26 at 11. Its right in the middle of the day and it's a good 45 minute drive so I might as well just take the day.

No , my current position is not near or near of being on my way back home.

What do I tell my current recruiter to get out of Monday for this interview/job I really want? The truth since they know the current is just a short term position and hope they take it ok? Call in randomly sick after a weekend?

I found out about this interview this past Friday late afternoon so no real time to start cooking a good excuse.
