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.
