A few areas of thunderstorms developed across the nation on Thursday. A frontal boundary extended from the Northeast, down the Ohio River Valley, and into the Southern Plains. Moisture from the Gulf of Mexico fed energy into this system, which allowed for showers and thunderstorms to develop. Heavy rains and strong thunderstorms developed in parts of Oklahoma and Texas, while lighter and more widespread showers and thunderstorms spread across the Mid-Mississippi River Valley and into the Northeast. There was a slight chance of severe weather development in Oklahoma and Texas, as well as parts of the Virginias and Maryland. Heaviest rainfall was reported at Fort Sill, Oklahoma with a mid-day total of 2.67 inches of rain. South of this front, warm and humid conditions persisted for the Southeast and Gulf states, with highs ranging in the 90s across the region. North of the front, cooler and dry conditions prevailed for the Upper Midwest and Great Lakes.

Meanwhile to the west, a trough of low pressure moved eastward off the Rockies and into the Central Plains. This created widespread shower and thunderstorm activity through the Central and Northern High Plains. Severe weather was not anticipated in these areas and rainfall totals remained less than a half of an inch.
