Wider weather episode

A midlevel shortwave trough was situated over the Upper Midwest Sunday night (31st) into Monday morning (1st). At the surface, a strong occluded low was also present. From this low and occlusion, a warm front extended to the southeast, lifting through the Commonwealth during the same time frame. A MCS developed in the Upper Mississippi Valley and continued to push southeast towards the Commonwealth during the morning hours. This prompted SPC to put portions of northern and eastern KY in a slight risk for severe weather throughout the day. Ironically, we did not see any severe weather out of this system - however, showers that developed during the morning hours ahead of the MCS were a different story. These showers developed over the eastern portion of the state, and impacted areas that were already heavily saturated from the devastating rains that occurred the week before. More so, the convection was moving parallel to the mean flow, which meant that many of these showers continued to train over the same locations for an extended period of time. This prompted flash flood warnings, and led to impacts in Martin, Pike, Letcher, Floyd, and Knott counties.
