Here is one of the latest computer models--the 12Z GFS for Friday night around 8:00 P.M. Remember this is just one computer model. But there are no big outliers at this time. Meaning, most of the models are showing pretty similar scenarios.
The box in the upper right shows rainfall. You can see the heaviest rain still offshore, but it's still not out of the question for a decent soaking, especially if the storm moves as little as 50 miles west. The box in the upper middle shows us where the center of the low pressure will be moving (offshore). The lines around the low pressure system are called isobars or lines of equal pressure. When those lines are close together it shows a big difference in pressure. And winds are driven by differences in pressure. Tight lines=VERY WINDY!
The bottom right shows accumulated rainfall which is tough to rely on at this point. But a soaking is not out of the question.
I would be more concerned at this point for people who live on Cape Cod. They will be closer to the storm's center and some nasty winds and rain may become a reality for them.
The cone in the picture to the right is called the "cone of uncertainty". The National Hurricane Center creates a cone around the forecast track to account for errors in forecasting or uncertainly in forecasting. That's why the cone gets bigger with time. But you will notice we are on the edge of the cone. So don't be alarmed if you see a map like this. It does not mean a hurricane is forecast to hit CT. But it means we need to watch this storm carefully because it's making forecasters at least a little nervous.
