The Fed definitely gets some economic data ahead of time. The transcripts of the crisis-era FOMC meetings showed this but not necessarily non-farm payrolls.

The next main event on the economic calendar is Friday’s non-farm payrolls. Did the Fed members get a sense of what’s in it? Let’s assume they did and look at the changes in the statement on labor.

First mention (with the prior statement struck out, new parts bolded):

Labor market indicators generally showed further improvement. The conditions improved, with the unemployment rate, though lower, declining further. However, a range of labor market indicators suggests that there remains elevated significant underutilization of labor resources.

Second mention:

The Committee expects that, with appropriate policy accommodation, economic activity will expand at a moderate pace, with labor market conditions will continue to improve gradually indicators and inflation moving toward those levels the Committee judges consistent with its dual mandate.

The first part continues to stress improvement in the overall labor market but talks about weakness in the details. If I had to guess, based on the theory the Fed had seen the statement, non-farm payrolls will be close to expectations but some of the details the Fed has highlighted including part-time jobs, underemployment and the participation rate will tell a less enthusiastic story.
