Expand It's gotten to the point that when we're at hour 84 we should just ignore the NAM and trust the RGEM. It's amazing how much more accurate RGEM is than NAM at that range.

lee59 Posted January 24, 2023 Share Posted January 24, 2023 It looks like the RGEM shows a small accumulation for the city, less than an inch. I hope but won't be surprised if there is no accumulation. Link to comment Share on other sites More sharing options...

So we wait until the main precip area hits, by which time the ESE wind warms up the boundary layer too much in the city. Makes sense is right and it's what happens in 90% of these. We get the lucky 10% every once in a while like 2/22/08, 12/14/03 etc but these screw jobs are the norm. Boston to Albany might get another few inches or more and continue leaping out ahead of us since it's looking like they'll be the area the overrunning hits. Expand 2/22/08 was amazing and you're right, it came in in the middle of the night! I don't think it was a Lakes Cutter like this one is either and both the air and water were a lot colder than they are now. Link to comment Share on other sites More sharing options...

eduggs Posted January 24, 2023 Share Posted January 24, 2023 Nothing of interest for as far as the models can reasonably see for the 55th day in a row or something like that. I vaguely remember some threats of interest in late November. The mid-range modeling has been really good. Unfortunately that has meant really boring tracking. 1 Link to comment Share on other sites More sharing options...
