Thunderstorm Wind — York, Maine

2021-05-26 · near Ossipee Mills, York, Maine

Event narrative

A severe thunderstorm downed multiple trees around the shoreline of Lake Arrowhead with a report of trees falling on boats.

Wider weather episode

An unseasonably hot and humid airmass moved into the region allowing for instability values more typical for summer. In addition, a pre-frontal trough approached Maine ahead of the main surface cold front located to the west in Quebec Province. A strong jet streak aloft allowed for strong 0-6sm shear profiles. These ingredients led to organized linear convection by the afternoon hours with multiple straight line wind damage across the southwest corner of the state.
