Here are updated model projections for cold front passing though tonight into tomorrow..
You can see the low pressure center developing on the front and just to the west. This is a little more west than yesterday so the heaviest rains might be more west as well. Here is rainfall through tomorrow..
Now lets focus back on the tropics. Here is the latest projection from the National Hurricane Center..
You can see the cone of possibilities and also the uncertainty with this system. Right now it appears two potential outcomes are evolving.
Outcome 1: The tropical storm get more absorbed in the frontal boundary and it "sheers off" its major development. This would mean heavy rainfall but no destructive winds.
The GFS operational model is showing this..
However, many of there ensemble members do in fact show a stronger storm due to..
Outcome 2: The tropical storm does not get sheered off by the frontal boundary and strengthens more. This would then the chance for a very powerful storm to turn into the coast.
The hurricane models (not always reliable) have been consistently hinting at this..
Don't get too worked up yet, I do not this think is a likely outcome.
We need to now turn to the ensemble guidance which takes the main models and adjusts them for potential error. You can see the GFS ensemble has a big spread still..
Looking closely you can see all the different low pressure centers from the ensemble. This represents where this storm can go based on GFS model. This shows you how there is high degree of uncertainty of how strong this storm really gets.
To sum it all up, here are the updated tracks from most major models..
You can see the spread but notice many members continue to show the storm effecting somewhere between NYC and the Carolina's. I will note these are not all strong storms for all of those lines but some are quite impressive.
Yes the worst case scenario is on the table but it is not likely at this time. Right now expect heavy rain this weekend and keep checking in for updates.
I am going to try to nail this thing down sometime tomorrow night or Thursday morning. Right now there is so much going on that its almost impossible for models to nail this down.
Update at 730 tonight after todays model runs.
