Tonight’s model data just becoming available.  Some large model differences have emerged regarding Tuesday’s snow.

The NAM has rain starting in the afternoon, changing to snow in the evening and quickly ending by 10 pm Tuesday night.  Total snow less than an inch.  QPF values about 0.31 inches water.

Tonight’s GFS continues with the idea that there will be low pressure development along the front.  It has precipitation starting early, changing to snow earlier and lingering.  QPF values about 0.63 inches water and over 3 inches of snow possible.

The important takeaway from this divergence is that there’s more uncertainty with this snow than previously thought.  Stay tuned.
