"In light of the data we've received this week – January reports for real consumer spending, construction spending, and net exports that varied from disappointing to downright weak, as well as a softer February print for car sales –-- we are marking down our tracking for annualized real GDP growth in Q1 from 2.5% to 2.0%. Even after this revision risks are more skewed to the downside than upside. By way of comparison, the Atlanta Fed's tracking estimate of Q1 recently came down to 1.2%. It's still relatively early in the quarterly data flow, even so, it is feeling eerily like Q1 of last year. In both cases the quarter began with high expectations, estimates were brought down as the quarter progressed, weather was blamed, but most forecasts remained upbeat on the medium-term outlook."
