August 13th featured a shortwave impulse moving across the Northern Plains with a weak surface low over South Dakota slowly drifting east. A trough extended southwest from the low across Northern Nebraska into Colorado where another surface low resided. Dewpoints were expected to be in the mid to upper 60s across Nebraska while surface winds were expected to be generally southerly with some backing along a stationary front draped across the northern portion of the state.

August 12th featured a shortwave trough moving across the Northern Plains into the Upper Great Lakes while a lee trough was forecast to develop across western Nebraska and eastern Colorado.

Generally westerly flow aloft as a trough edged in from the Pacific Northwest while at the surface a surface low was progged to develop in NE Colorado and drift eastward while a dryline extended south through Western Kansas into New Mexico. SPC had outlined a slight risk along the dryline from Kansas south along the Texas/New Mexico border. Marginal tornado probabilities extended along the same region as well as a bit into Nebraska closer to the low.
