The wider storm

On June 26th an approaching cold front associated with an upper level shortwave trough brought strong shear and modest mid level instability to New Hampshire. Daytime heating was near seasonable norms, but still enough to create amble low level instability as highs reached the lower 80s. A few long track storms created a swath of hail and wind damage from Sullivan to Rockingham Counties.

Began near Blodgett Lndg (43.3600, -72.0100).
