Almost Time to Go
[Part 4 of 4] One more view of the low-topped squall line treated us to a textured convective underbelly, rolling along before the most dense part of the core. Within a few minutes, cold rain and embedded small hail would be likely, so we headed N into St. John to ride out the fast-moving thunderstorm band. Soon afterward, it outran the narrow corridor of solar-heated air that supported its meager inflow-layer instability, and weakened. We were fortunate to catch this convection at its peak, on a day when we hadn't planned on any storm-intercept activity at all.
