### SUMMARY
Severe thunderstorms appear unlikely on Saturday.
Synopsis
Broad, upper-level troughing will persist across the CONUS on Saturday. A mid/upper shortwave impulse embedded in larger-scale flow over the Rockies early in the day will eject eastward across the Plains and into the Midwest through early Sunday. As this occurs, the southwesterly subtropical jet over Mexico will merge with strong westerly flow associated with the ejecting shortwave trough over the southern Plains and mid/lower MS Valley Saturday evening/overnight. At the surface, low pressure will develop east and northeast along a frontal zone from the southern High Plains into the upper Great Lakes vicinity. This will allow for southerly low-level flow and northward transport of Gulf moisture across the south-central U.S. This will aid in development of weak instability across east TX toward AR into western MS/TN overnight. Warm midlevel temperatures will result in capping for much of the period. However, midlevel moistening along with increasing large-scale ascent will support isolated thunderstorm development after 03z, though severe thunderstorms are not expected.
