Well, the flip side of that is "why do we have forecasters if we have these elaborate computers resolving meteorological physics from the data concerning initialized conditions being fed to them"????
Well, first of all, we don't know if all of said data being fed in is correct....Secondly, forecasters can add an element of subjectivity that the computer cannot and make a determination regarding which output is likely to actually occur and which is not. It has become obvious to me that the ridge alignment out west just sucks this season in that it does not allow for proficient enough phasing close to the northeast coast because it's poorly situated and oriented. However, for whatever reason, the guidance is blind to that in the extended medium range and keeps trying to develop these tempests that strike the NE US coast, but once we get within 5 days, they can more adequately resolve this and arrive at the correct, dull solution.
Express whichever sentiment you wish, but the ultimate mediator is the scoreboard.
