IERS Bulletin A gives an expression for the uncertainty of its UT1-UTC
data predictions:
S t = 0.00025 (MJD-today)**0.75
where today is the MJD of the bulletin's publication. The Bulletin
only predicts a year ahead. Applying that formula gives an uncertainty
a year ahead of 21 ms. It

It has been remarked that the current state of the art is that 100ms
accuracy can be predicted about a year in advance only and that the
models are constantly undergoing refinement. It has been estimated
that IERS could issue leap
