What happened

The episode as NWS LWX wrote it up.

Unseasonably warm and humid air plus developing low pressure over the Ohio Valley produced bands of heavy rain across portions of north central Maryland. The combination of tropical rainfall, saturated soil (due to recent snow melt) and time of year led to flash flooding of numerous small streams, creeks, and low-lying areas - especially in Frederick Co.At least 40 secondary roads, and several major thoroughfares, were closed during the morning. Included were state routes 26, 351, and 880. At least three vehicles were stranded on back streets in the city of Frederick. Rainfall totals averaged between 2 and 3 inches. Portions of the Big Pipe Creek watershed in northern Carroll Co reported flash flooding, with 3 or more roads closed. Some flooding was reported on the Monocacy River in the town of Detour.
