RDRY Posted December 3, 2020 Share Posted December 3, 2020 The only model that showed anything close to warning snows in western Mass was the 12z GFS, with ensuing model runs trending further east.

Expand It certainly is hit and miss (which even be said with the HRRR at 12 hours) but it's really great for assessing consistency and trends. So let's say the 0z HRRR tonight is in line with the NAM and then each subsequent run remains consistent...even though other guidance is suggesting otherwise, seeing the HRRR be consistent I think would be a strong indicator. not sure how well this works with winter weather but the idea works great with convection.

USCAPEWEATHERAF Posted December 3, 2020 Share Posted December 3, 2020 I will take the cold hard rain in wind over 60mph from the east or northeast! If the winds are northeasterly the NWS used to say during nor'easters that the northeast wind was unstable and therefore able to mix the hurricane force winds to the surface, like JUNO, NEMO and others!

I just don't have a good feeling on this one for us up here. They NH hype machine starts on the 6pm news tonight. Expand Haha it's kind of always funny seeing the local news a step behind the forum. They are going to use this mornings and afternoon model runs to hype up the potential for a significant warning criteria storm in NH, while we watch this evenings model runs live shunt this east and possibly give more significant impacts to SNE. Not that I'm ready to jump ship for CNE or NNE on this as I alluded to in my last post....I just get a chuckle watching the local news rely on previous runs while mets on here are starting to discuss entirely different scenarios. Showing old data certainly adds to the "weatherman get paid to be wrong" mentality I hear the general public gripe about all the time but I also get why showing the most recent model runs on such short notice on a live broadcast is problematic especially before the meteorologist on staff hasn't had the time to fully analyze those said model runs.

Meteorology over modelogy? Expand Exactly. The snowfall algorithm that I tout is superior with respect to distinguishing precip type issues, which is usually important for us. Most algorithms err by tallying mixed precvip as snow, which inflates the numbers. Mine does not to this, however, it is only based on the model, which usually will not resolve mid level banding properly. Thus it will miss the deformation axis to the NW of the low.

Expand Are you talking about the QPF charts, or mid level model depictions? if the mid levels trend east, and/or the system matures later, then yes.......but not because the QPF chart simply doesn't show big amounts. Models mainly resolve precipitation from low level forcing, but are not skilled with mid level deformation...vastly underdone. 1 Link to comment Share on other sites More sharing options...
