...NO SEVERE THUNDERSTORM AREAS FORECAST...
CORRECTED FOR WORDING
...SUMMARY...
Isolated thunderstorms remain possible tonight over the northern and
southern High Plains. Severe thunderstorms are not expected.
...Synopsis...
A mid-level trough continues to progress across the northern
Rockies, providing enough mechanical lift amid cooler temperatures
aloft to support isolated high-based thunderstorms atop a dry
boundary layer. A low-amplitude mid-level impulse will also continue
to traverse the southern Rockies, supporting scattered lightning
flashes given the presence of scant buoyancy. These storms should
gradually diminish through the evening as boundary-layer
stabilization from nocturnal cooling takes place.
