18Z NAM

Here's the NAM from the 18Z run (earlier maps were from the 12Z run).  Usually the 18Z models are taken with a grain of salt and usually just used to identify trends in the forecast or inconsistencies.

The NAM is pretty consistent with its slower, stronger philosophy although this low position is about the same but the precipitation shield is further west than that of the 12Z run at the same forecast time.

Here we see the phase occurring and some light to moderate snowfall over our area at about 1 AM on Wednesday.

No change to forecast at this point.  No significant model trends to suggest that the forecast is off track.
