The episode as NWS MLB wrote it up.
Showers and storms formed during the afternoon and produced outflow boundaries, which collided, causing additional showers and storms. The steering flow was very weak, resulting in a very slow storm motion. The heavy rain produced temporary, mostly minor flooding, particularly in Lake County.

TEMPS WILL FALL INTO THE LOW/MID 70S ACROSS THE REGION. WED-FRI...SUBTROPICAL RIDGE AXIS WILL SHIFT GRADUALLY SOUTHWARD FROM MID TO LATE WEEK AS AN AREA OF LOW PRESSURE OVER THE MIDWEST PUSHES EASTWARD AND DRAGS A COOL FRONT INTO THE SOUTHEAST UNITED STATES.

THE DEEPENING EASTERLY FLOW WILL TEND TO ALLOW EARLIER EAST COAST SEA BREEZE FORMATION AND QUICKER INLAND PUSH EACH DAY. EXPECT SEA BREEZE COLLISIONS WEST OF ORLANDO IF NOT WEST OF LAKE COUNTY. TEMPERATURES ALOFT WARM TO AROUND -6C WHICH WOULD TEND TO REDUCE THE POTENCY OF ANY MID TO LATE AFTERNOON STORMS OVER THE INTERIOR. HIGHS FORECAST TO RANGE FROM THE UPPER 80S AT THE COAST AND LOWER 90S INLAND.
