The potential for thunderstorms appears low across the United States


Strong mid-level height falls, on the order of 180m in 12hr, will
spread across the southern Rockies into the southern High Plains
late Saturday ahead of a progressive southern-stream short-wave
trough. While low-level trajectories will respond and become more
favorable for moisture to advance across the western Gulf Basin into
TX, the primary influence of this strong feature will occur later in
the day3 period as moisture/instability increase prior to frontal
passage. Until greater buoyancy materializes inland, the threat of
thunderstorms will remain low and the probability for lightning will
remain less than 10 percent.
