Episode narrativeepisode_narrativeFor the second time in a week, a localized heavy-rain-only event (no severe storms) forced the South Fork Solomon River above minor flood stage in Osborne County. Unlike the previous event, during which the axis of heaviest rain fell almost directly over the Solomon basin (including in the city of Osborne), this time around the instigating heavy rain fell in a west-east oriented swath about 10 miles farther south as a multicell storm cluster remained quasi-stationary for nearly three hours from 6-9 p.m. CDT on Tuesday the 30th. Radar rainfall estimation suggested that the heart of this narrow swath across central Osborne County averaged 1.50-3.00. However, a trained spotter near Covert happened to live within a very small (likely no more than a few square miles) bullseye of heaviest rain and reported an unofficial total of 5.50 inches along with water over some rural roads. While most of these initial, short-term areal flooding issues improved during the overnight hours, considerable runoff flowed down smaller streams such as Covert Creek and Kill Creek and eventually into the South Fork Solomon River, where the gauge at Osborne breached minor flood stage of 14 feet around 7 a.m. CDT on Wednesday the 31st. The river crested at 16.7 ft. during the afternoon (2.7 ft. above flood stage) and fell back below flood stage around 10 p.m. CDT. ||The isolated to scattered, slow-moving heavy rain storms that roamed North Central Kansas on both the 30th and 31st occurred in a classic weather pattern for localized/spotty heavy rain and flash flooding largely driven by diurnal heating. In the mid-upper levels, flow was very weak (especially near/below 500 millibars) with broad ridging in place, although weak, transient mid level disturbances were evident in the flow. This subtle forcing aloft interacted with an airmass very moist through a deep layer, featuring impressive precipitable water values in the 1.5 to 2.0 range and tall/skinny CAPE profiles with weak mid-level lapse rates.
Event narrativeevent_narrativeAn unofficial rain total of 5.5 inches was reported near Covert. This occurred in a span of 2.5 hours. Rain was ongoing at the time of the report, but not nearly as heavy. Some roads in the area reportedly had water over them.
