A strong cut-off and negatively tilted low pressure system brought widespread heavy rain and strong wind gusts to south central Nebraska on this day. An anomalously deep low pressure system slowly migrated from the Four Corners region on March 13 to the Central Rockies on March 14. Strong/deep southerly low to mid level flow brought copious amounts of moisture from the Gulf of Mexico, leading to precipitable water values near the climatological max for mid March. The deep moisture advection, combined with slow moving nature of the upper trough led to the development of widespread showers and weak thunderstorms during the day of March 13 that persisted well into the daytime hours of March 14. Luckily the area had been warm and relatively dry after a very cold and snowy February, which had this not occurred prior to this event, there very well could've been a repeat of the historical March 2019 flooding. Also fortunate for the area was that instability remained weak throughout the 13th and 14th, which helped to limit the rainfall rates and avoid a more significant hydrological event despite the widespread 2 to 7 inches of rain! Both Grand Island and Hastings broke back to back daily rainfall records on the 13th and 14th, respectively. In addition to the daily records, Grand Island also broke records for most precipitation in a calendar day and for the overall March total!  So needless to say, this was a very significant rainfall event for the area, let alone for mid-March. Despite the significant rainfall, overall hydrological impacts were limited, owing to the aforementioned limited rain rates.
Another aspect of this system was the strong winds. The depth of the surface low was not particularly deep, only around 1000 mb, but the pressure gradient was still impressive due to a strong area of surface high pressure in southern Canada. This resulted in a nearly 20 mb gradient from southwest to northeast across the state of Nebraska. Peak wind gusts from this event were near 60 mph, centered in the area between the KS/NE state line and Highway 92 and occurred from around sunrise through around noon. Thereafter, winds slowly subsided as the pressure gradient gradually relaxed. Impacts from the wind ranged from minor tree damage to a damaged car port.
