Gusty thunderstorms with heavy rain and lightning passed through CT Wednesday night.
Although the typical thunderstorm parameters were not very impressive at all, a line of storms managed to hold together as it moved across New York and into southwestern Connecticut.
Typically, parameters like CAPE (available potential energy), the lifted index and high dew-points are favorable for strong thunderstorms. However, Connecticut didn't really have any of those things in place last night.
I was a bit interested too in how this line of storms, which had some characteristics of a Mesoscale Convective System (MCS), maintained itself in a relatively (seemingly) unfavorable environment for thunderstorms.
In this slide-show, I'll take a look back at some of the conditions that were in place, as well as a severe weather parameter called MCS Maintenance Probability, or MMP.
