Wednesday November 24

We are in a mode of rapid transitions over the next few days. The good news is that this timing works out with the best weather for Thanksgiving.

Rain will arrive overnight Thursday and ending Friday morning, with colder air moving in. 

This is the time of year we need to track potential snow.  The next round will be Friday in far western Maryland (Garrett County).  

Sunday, a clipper will be racing in with light snow possible in ‘some’ metro areas. I mentioned this in my report last night. Today it has even more support. 

What to wear?

It is cold again, but there will be more sun and less wind. So layers and a coat, but it will feel better later. 

Morning Surface Weather

 High Pressure dominates the eastern US.  

A brief warm up will reach us tomorrow. The next cold front is crossing the middle of the nation and will reach us Thursday night.

A band of rain will mostly pass overnight. Some may linger on Delmarva in the morning. 

Snow will develop in far western Maryland with a coating to 2 inches possible. 

Jumping To Sunday

Could this be the day for first flakes?  Last night I showed the case behind the Clipper racing in supported by the European Model, but barely showing up on the GFS. This morning. Both appear to be in line.

This is a summary of 6 hours between 1 PM and 7 PM Sunday.

There is a good chance for some accumulation and road impact in the mountains.  We will need to watch the timing, temps, and potential locally impact in our western and northern suburbs.
