UPDATE Maryland storm this weekend

By: cws6196 , 2:35 AM GMT on October 23, 2012

As l mentioned yesterday, the storm, or hurricane, is not a guarantee but something we need to be watching. I just want to remind you that what you hear, and even what I write, is speculation this far out. But, I do feel you need to know of possibilities even if the situation never arises.

The previous area of interest in the tropics is now tropical storm Sandy. Current tracks have her moving north over Cuba by the end of this week. Models tend to agree with that path, but after she moves north of Cuba the models are all over the place as to the path she will take. A few of those solutions have her coming up the east coast. Bottom line, will she impact us here in Maryland?

The key word here is timing. This weekend we will see a strong low pressure system in southern Canada move across the Great Lakes to the east. As this strong low moves east it will create a trough, or a "U" shape dip into the south and coming back up through MD. Depending on the exact track of Sandy and her position when the Canadian low moves east will help to determine her impact. Depending on the timing, the trough could either move Sandy out to sea or draw her inland. It all depends on the timing and position.

Some people are talking about a "perfect storm" potential. What they are referring to is the potential for these two systems to merge and interact with each other. Again, timing is the issue here. In one scenerio we could see strong winds and heavy rainfall along the MD coast while central and western MD experience snow. Will we see snow? Too soon to tell, but it is looking good for western MD and PA to see snow this weekend.

At this time it is too early for me to say what will happen, but I do see unsettled weather later this weekend into early next week. I don't see acatastrophe nor a reason for people to panic. If you hear of people saying otherwise it is only speculation. Once Sandy passes Cuba and we see the timing of the Canadian low will we have a better idea of what will effect us.
