A trough across north-central Florida lifted northward through the day. An anomalously moist airmass (PWATs near 2.2 inches) remained over the area. Weak east-southeasterly flow led to a dominant Atlantic coast sea breeze shifting inland in the afternoon. Heavy rainfall amounts from thunderstorms occurred across portions of northeast Florida near the lifting trough axis and sea breeze boundary convergence enhanced by a passing upper shortwave. Weak northeasterly steering flow to the north of the trough then drove storms southwestward in the late afternoon and early evening. These slow-moving storms brought about 4.5 to 6 inches of rainfall causing multiple streets to flood and water to encroach and enter buildings in the HWY 301 and I-75 corridors.
