Wider weather episode
Moist, unsettled SW steering flow and low-level convergence brought an early start to storms across the Suwannee River Valley. A short-wave trough impulse approached from the west in the afternoon over an unstable airmass, that further enhanced convective growth as storms approached the Atlantic coast. A strengthening low-level jet prevented the east coast sea breeze from moving far inland but did enhance downdraft strength in storms.
