Wider weather episode

An unseasonably hot and humid airmass brought unstable conditions to southern New Hampshire as high pressure to the east allowed warm air from the southwest to move into the region. A weak mid-level disturbance triggered storms to develop by mid-afternoon across southern and central New Hampshire. A few of the storms became severe downing trees along with some large hail.
