The image above shows my predictions for the storm which will affect the region Tuesday into Wednesday. The storm is the union of a feature on the subtropical jet (southern) and the polar jet (northern) as shown below. The subtropical feature should offer moisture, allowing for heavy rains, and the polar feature should offer atmospheric energy, allowing for gusty winds.
The map below shows expected wind speed at the 900mb level, which is about 3000feet in elevation. The brighter oranges indicate sustained wind speeds of about 75mph at that level. This means that there is a potential for strong winds of 20-40mph near the Connecticut shoreline and at mountaintops. 
If the system is slightly slower than expected there is a chance for some severe storms may arise Wednesday mid-day to afternoon across. If this occurs Connecticut may also experience heavy rain Wednesday, but the idea of a second thunderstorm event Wednesday is still uncertain.
