...Severe weather is possible across the central Plains and upper Midwest over the next couple days...
A mid-level trough will escort a frontal boundary through the Southeast
down through the Florida peninsula and along the central Gulf coast over the next couple days, acting as a focus for thunderstorms through the period, particularly during the afternoon and evening hours driven by daytime heating. Thunderstorms are also possible in the morning, which move ashore from the adjacent Gulf of Mexico and western subtropical Atlantic to coastal sections during the early morning hours, driven by the low-level flow around the boundary.
A deep cyclone will move from southwestern into south-central Canada, driving a weak cold front through the northern Plains and Great Lakes. This boundary should act as a focus for thunderstorm activity as it moves through the region, some of which could be severe per guidance from the Storm Prediction Center. During the overnight hours, elevated thunderstorms should migrate eastward before dissipating during the mid to late morning.
Across Texas, moisture streaming in from the Gulf of Mexico -- aided by a nearby upper-level low -- sets the stage for showers and thunderstorms across the Trans-Pecos and Big Country of the Lone Star State through the period.
