Episode Narrative

Heavy rainfall and severe storms affected Central Alabama on February 5th and 6th as several impulses emanated from a deep upper trough centered over the central United States. This event yielded tornadoes, damaging winds, and flooding.||The northward progression of a warm front allowed a seasonably warm and moist air mass to overspread the region on Wednesday, February 5th, with afternoon temperatures in the 70s and dew points in the 60s. The initial round of convection on this day included areas of rain with embedded thunderstorms producing gusty winds as well as hail. There was a relative lull in thunderstorm activity during Wednesday evening, before the next upper-level impulse arrived, alongside a cold front and nearby surface low. This round of activity began its formation to the west in Mississippi and then moved through Alabama late Wednesday night through midday Thursday, February 6th. This round of convection produced widespread moderate to heavy rainfall, resulting in more substantial flooding. Some storms became tornadic due to the favorable wind shear and instability in place, while others produced damaging straight-line winds. Due to the overall wet and breezy conditions, trees fell in numerous locations from wind not associated with thunderstorms.
