usedtobe Posted January 19, 2012 Author Share Posted January 19, 2012 nice post...pretty much what I expected....explains everything well Thanks, I think for us in the city, the 18Z gfs and nam are pretty bleak unless you are going to be up at 1:00 Am tomorrow nite as the slight differences in the pressure pattern and 10 kt winds as opposed to 5, suggests that the cold air may erode faster than the earlier nam was predicting. That said, it may be hiccup or it may be real. My guess is the latter but I don't really know. Link to comment Share on other sites More sharing options...

usedtobe Posted January 19, 2012 Author Share Posted January 19, 2012 If that sounding were absolutely perfect, it would be rain, drop the surface temp 2 degrees and it might be freezing though the droplets might not be in the cold layer long enough to droplets below freezing. The 18Z gfs and nam don't look pretty and I can see why Bob Ryan is downplaying the event. If this holds until tomorrow, the CWG will probably back down from what I wrote.
