From the NY Fed Nowcasting Report

The FRBNY Staff Nowcast stands at 2.6% for 2017:Q1 and 2.1% for 2017:Q2.

Incoming data during the week lead to a reduction of the nowcast by 0.2 and 0.5 percentage point for 2017:Q1 and 2017:Q2, respectively.

The changes in the nowcast were mainly driven by a negative surprise from retail sales.
