(CNN) - Let's start with the obvious question: Will the government shut down this week? Most likely.

Republicans and Democrats can agree on that. It's everything else that has them bickering and blaming. And unless they strike a deal on a spending bill Monday, the government will begin closing shop at 12:01 a.m. Tuesday.

After weeks of congressional back-and-forth, the ball is now in the Senate's court. It meets at 2 p.m. Monday to decide what to do next.

A shutdown, while likely, isn't a foregone conclusion. The deadline is midnight - and one day can be a long time on Capitol Hill.

Here's a quick Q&A to get you caught up on what happened over the weekend and what to look forward to Monday.
