So, even with the intensified negotiations over the past several days on the next COVID relief package, it appears very unlikely that the different sides will reach an agreement before the clock strikes midnight tonight. Even the various sides were to get to an acceptable compromise, it would take time to turn that into legislative text. This means that another continuing resolution (CR) will be needed to prevent a shutdown. The House is currently voting on a two-day CR, which would extend funding through Sunday.
While Senate Majority Leader Mitch McConnell (R-KY) has committed to keeping the chamber in session until a final COVID package is passed, it remains to be seen how long that will actually take.
