sweetapricity/bridgedeck-noaa huggingface dataset:
Low pressure rode up the Ohio Valley during the nighttime and early morning hours of February 12th to the 13th.  An anomalously moist air mass with precipitable water values of near or just over an inch, combined with warm advection and right entrance region jet dynamics, produced widespread precipitation across the region.
The heaviest rainfall was observed south of I-70, where totals of around an inch fell on nearly saturated ground.  This led to several instance of flooded roads and landslides across portions of southeast Ohio into southwest Pennsylvania.  Further north, where warm air was unable to fully penetrate, accumulating snow was observed.  Reports of around three inches of accumulation were received Carroll and Columbiana Counties. A brief period of icing was also noted, but was of little impact.

A shortwave trough diving southeast across Eastern Oklahoma and Western Arkansas in the northwest flow aloft during the evening through the early morning hours of May 7th-8th, enhanced large scale forcing ahead of an attendant cold front, resulting in a complex of showers and thunderstorms to develop near and ahead of the front. This mesoscale convective system, or MCS, quickly shifted southeast into Southeast Oklahoma, Southwest Arkansas, Northeast Texas, and North Louisiana during the early morning hours of May 8th, strengthening as it encountered greater instability and a strong southerly low level jet. This resulted in the development of severe thunderstorms containing damaging winds, triggering numerous reports of wind damage across these areas. These storms exited Southeast Oklahoma prior to daybreak on the 8th.
