Arcitc air back in place....potential big system next week....

Take a look at today's video...I step you through some of the modeling and give you some thoughts on what could be a major eastern US storm system next week....



Colder air has again arrived....and we will be generally quiet and chilly all weekend.

I will skip right ahead to the system next week. Most of the models have converged on a solution that consolidates the upper level energy into a powerful upper level low that develops roughly over the Ozarks and winds up overhead in the Carolinas. This results in a phasing, rapidly deepening low pressure that tracks from the northeastern Gulf of Mexico to near or just inland of the Carolina coast and finally up to the New England states.

Now, I will caution here that, like some of our previous systems, we are talking about the precise interactions of upper level features in this fairly chaotic pattern, and some changes are quite likely.

But as it stands now, I would lean toward an idea something similar to what the GFS and Euro modeling is showing. What precip types any individual location would receive would depend entirely on the track and intensity of the surface low. For many Piedmont areas, this could be a snow to rain then back to snow scenario. But these details are really not even worth getting in to at this point.

So we will see what happens. If the energy aloft stays consolidated, then a major system is quite possible. If the system deepens too soon, many in our region could get a driving rain storm. If it deepens and tracks just right, it could be a biggie for somebody in the region.

But please hear this...the solutions that the Euro and GFS have shown this morning are rare events and very difficult to come by. So, I would not be surprised at all to see this intense solution not verify.

Like I said yesterday, I will likely not have any real confidence until a couple more days pass. Lots of players on the field here. As I said in the comment section, now is not the time for celebrations or pity parties. Lots will likely change in coming days.
