Good Saturday afternoon everyone. The blog is upgrading to Winter Storm THREAT for Tuesday and Wednesday. The THREAT does not mean this storm is certain to hit our region… it simply means there is an increased risk for a significant snow event.

The setup will find low pressure developing across the gulf states late Monday into Tuesday. This low would rapidly intensify as it heads northeast into the Carolinas then into the northeastern part of the country. While the exact track of this low won’t be known until later Sunday or Monday… there is more than enough reason to think much of our region can get in on the significant snows.

Here is a breakdown of the threat area…



That is basically a First Call for the Winter Storm Threat and I will update that as needed as more data becomes available. Those lines can move east or west in time.

The latest round of computer models look very threatening, for the most part. The Canadian Model has been steady as a rock in showing how a major winter storm…



Here is the amount of liquid precipitation from the same model forecast…



To help put that in perspective… A general rule is 10″ of snow for every 1″ of liquid. The JMA model is even farther west with the heaviest precipitation…



We also find the NOGAPS… UKMET and NAM in a similar camp in terms of the track of the low.

In the opposite camp… we find the GFS and European Models suggesting this storm will have very little impact around here or up the east coast, for that matter. You know what I think of the GFS as it JUST today figured out there would actually be a storm. It is in it’s typical too far east mode with an east coast storm and you will see it correct westward over the next day. The European has been all over the place with this storm as has shown everything from 2 feet of snow to nothing around here in the past few runs. This used to be the mac daddy of models, but has had a lot of issues the past few winters… especially this one.

There is PLENTY of room for error with this storm as it is all about the track. A farther eastward track means less snow for us while a farther west track could bring a shutdown snowstorm to us. While I cannot say for certain where the track will end up… the potential is certainly there for us to be in the middle of a major winter storm. I am not saying you are for sure getting a snowstorm… just that we have an increased risk of one.

Let’s get into Sunday and see how things are looking before we stock up on bread and milk. haha

I will have more updates as needed so be sure to check back. Have a great rest of your Saturday and take care.
