One of my favorite tools for snow forecasting is a piece of software called Bufkit. It was developed by the National Weather Service Office in Buffalo, New York. Bufkit is terrific for analyzing model data and displaying precipitation type. I took the 00z NAM data from this evening and loaded it into Bufkit and it looks like we'll see a rain/snow mix Monday night beginning around 6pm and switching to all snow sometime after midnight. Snow will most likely linger through Tuesday morning. Snow is indicated by blue and rain is displayed by green. At the bottom of the graphic is the time (read from right to left). There is not much question on whether this system will create snow. I think that will happen. I do not think it will cause travel issues because the ground temperatures as I've mentioned are too warm. In fact - the air temperatures should remain just slightly above freezing. I do think it will pretty to look at as it falls early Tuesday.
