Monday January 23 – We are still under a Wind Advisory and there will be some bands of heavy rain this afternoon. Baltimore’s BWI had a top gust of 43 mph so far. Imagine the open elevated bridges might have very well been higher. The purpose of this post is to add some support to how this storm redeveloping on the coast will help create its own cold air. This morning I mentioned some snow might mix overnight, but now it looks like there could be a bit more. Before we get too excited, I have already alerted my clients to let them know that even in the coldest spots, the ground is warm and will have trouble supporting stickage, even through Tuesday morning. But some coating on the grass north and west of Baltimore is possible. Here is the set up, with the radar simulation below…
The main area of Low Pressure is now transferring the energy to the coast. This will help support the northeast to north wind that will hold the chilly air in place and bring in colder air tonight.

We are in the peak of this pressure gradient mid day… the winds will ease a little this evening, but the main issue will be the shift in direction… turning more to the north and northwest tonight. That will help the colder air feed into the storm. Especially at cloud level.
