We are now under 2 days ( 48 hours) from the onset of wintry weather across the state. If you missed my first blog on Wednesday going over the setup we have taking shape, you can find it here: http://noapologyvameteorology.blogspot.com/2013/12/late-weekend-ice-storm.html . On that blog I I mentioned that I would wait and see what the NAM model would show once it started to get within its range since it usually does the best with cold air damming in Virginia. I had someone ask me what 12z and 00z means. In short, 00z are the late night and the 12zs are the early afternoon weather model runs. On to the models. Here's the 12z nam. I know some might say its not yet within its "best" range as a model...which is usually once we get to within 48 hours of an event, but it is at least worth noting that the model has come in much warmer than it was during its 00z run last night. In each image, left panel is the precipitation while the right is the 2 meter temperatures. I highlighted in white where the 32 degree line is.
