Rain for Christmas Day?

It looks like we should see some rain showers during the evening hours of Christmas day; hopefully, the rain will stay offshore until the nighttime hours. Here is what I think is going to happen: A low pressure is going to develop off the coast of Georgia. This low should travel up the coast moving away from the area toward the north.

Here is the 6Z 12/25 image from the 12Z NAM run. It looks like this low won't be very strong. It should just bring us some small rainfall amounts. In most areas, we should get a quarter of an inch.



On the other hand, the GFS 12Z run suggests the low will be a much broader low pressure system. This would mean that the low isn't as strong which would usually result in less rainfall.

So for all of you that ask: Are we going to have a white Christmas?

The answer is unfortunately 'no'. We most likely will not see frozen precipitation.
