Just three weeks ago, the consensus of about 60 top economists was for a weak 1.3% growth in the first quarter of 2019, but the early indication of a good surprise has appeared.

Throughout every quarter, the Federal Reserve Bank of Atlanta estimates GDP growth dynamically based on publicly available data until the release of the actual GDP figure three weeks after every quarter ends.

The Atlanta Fed's GDPNow forecast is designed to grow more accurate in the closing days of every quarter and in the three weeks after every quarter, before the actual GDP figure is released by the Commerce Department.
