Took a quick look at Gary Gray's Winter Weather Discussion which is very informal but long winded. Here are some important points: <BR> <BR>"My thinking: I'm having a bit of a tough time with this one. My big concern is that the storm will be slower and stronger than predicted. The reason for this concern is simple... an examination of the 12Z radiosondes shows that almost all of the 00Z models were too weak with the system... by quite a lot in some cases. Moreover, the models were even a bit too weak in their 12Z initializations... every last one of them! I have checked for any special 15Z or 18Z radiosonde launches. There were not any that would help the models out. So, it would be a giant leap of faith to expect the 18Z model runs to be any better.... <BR>Up to the north into PA/N NJ/SE NY/New England, there is much less question mark... heavy snow. The differences in the models are practically academic. That is, in the areas that get bombed in parts of New England, the difference between, say, 15" and 24" is notable, but not enough to really change the impact very much... The impact would be quite significant. There are SOME details to struggle with up north, though. For example, the GFS/RGEM shove the very heavy snow back further into more of NY. I am leaning towards those solutions. Why? Because even if only a GFS/ETA compromise verifies, the snow to liquid ratios back into interior eastern NY may be high enough to crank up the snowfall anyway. <BR>Full discussion and a forecast map at the bottom that is quite conservative in some areas: <BR><A HREF="http://www.millenniumweather.com/winter/cast2.html" TARGET="_top">http://www.millenniumweather.com/winter/cast2.html</A> <BR> <BR>-Scott
