Discussion:
A line of thundershowers formed early Friday afternoon near the I-91 corridor in central Connecticut. Those storms have dropped some locally heavy rainfall, prompting some short-fused Flood Advisories for portions of Hartford and Tolland Counties. Any showers or thunderstorms today could cause localized flooding.
Other showers and thundershowers have popped up across the area. More of the same is expected throughout the day. Since daytime heating is not being maximized, there is not a whole lot of instability in the atmosphere. With that said, a few stronger storms are possible, especially late this afternoon. At that time, a downstream upper level disturbance will approach from the west. This may enhance some convective (thunderstorm) activity, but the timing appears too late for widespread severe thunderstorms. The end result is just an isolated severe threat in Connecticut. Further west across Pennsylvania, more widespread strong to severe thunderstorms are expected. As of 2 p.m., a Severe Thunderstorm Watch was in effect for that area.
