| Episode narrativeepisode_narrative | A surface low pressure system that moved across South Dakota and Minnesota, dragging behind it a cold front that moved into portions of northwest and central Iowa on the 30th of September. As the surface front moved through Iowa, it stalled out and effectively divided the state in half as it oriented it self from southwest to northeast across the state. While the itself stalled, it separated two distinctly different air masses with temperatures in the 50s to low 70s prevailing on the north side and 80s to around 90 prevailing to the south. Surface moisture was also divided with dew points in the 50s on the cool side and low to mid 70s on the warm side. ||Showers and storms persisted north of the front overnight of the 30th into the 1st and during much of the day of the 1st. That activity yielded little more than periods of moderate to heavy rain and sub-severe thunderstorms. Along and south of the front, thermodynamic and kinematics yielded much more vigorous storms and ultimately heavy rainfall and severe weather. SBCAPE profiles yielded 2000 to 3000+ J/kg by early to mid afternoon along with effective bulk shear around 50 to 60 kts, and persistent strong moisture flow yielding precipitable water values around 1.75 to 2.0 inches. Additionally, in the lowest 1 to 3 km, CAPE values exceed 100 J/kg and was accompanied by enhanced low level helicity due to frontal proximity. As a result, virtually all modes of severe weather were possible. In the end, the majority of reports revolved around severe hail, nearing 3 inches in diameter, and heavy rainfall in excess of 3 to 4 inches. A handful of funnel cloud and damaging wind reports were also received. |
