...Synopsis and Discussion...
Multiple low-amplitude, mid-level shortwave troughs are forecast to
develop east-southeastward today and tonight from parts of the
northern/central Plains into the Midwest and OH Valley. Rather
meager/shallow low-level moisture will tend to limit thunderstorm
coverage and intensity across these regions. Even so, sufficient
large-scale ascent and weak MUCAPE may still support isolated
convection capable of producing lightning through the period.
Occasional strong/gusty winds may occur with high-based
thunderstorms across parts of SD/NE this afternoon, but organized
severe thunderstorms are not forecast.
