The plots below shows the evolution of 24-hour precipitation for NYC (left) and Albany (right) for 13 March from ECMWF (red), UKMO (blue) and NCEP (green). For NYC the signal was picked up at a similar stage (9-10 March), while the northern extend was picked up later (11 March by ECMWF). NCEP picked up the northern extent earlier (9-10 March)) but lost the magnitude on 11 and 12 March. It is agreement with the NCEP HRES results and it is also worth noting the lower spread in the NCEP ensemble.
