Winter Storm Watch in Effect - Significant Snow on the Way

Just a quick post to update everyone on the current snow situation -

The afternoon models are running right now and they seem to be holding onto the idea of significant snow for the Washington area tomorrow afternoon into tomorrow evening. The 18z NAM model clearly shows some significant energy on the 500mb map. For the lay people reading this posting - the 500mb level is high in the atmosphere, and maps from this part of the atmosphere are useful in diagnosing where certain features are.

500mb level map from the 18z NAM model. Strong indicator of the potential of snow in our area. 

This map would indicate a strong chance for snow in our area - more later.
