Day 1 Convective Outlook

1135 PM CST Sun Nov 28 2021
Valid 291200Z - 301200Z
...NO THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Thunderstorms are not expected across the U.S. today or tonight.
...Synopsis/Discussion...
Stable conditions and seasonally cool temperatures are expected to
preclude thunderstorm development across the CONUS. A progressive
and semi-amplified large-scale pattern will persist across the CONUS
with a general prevalence of northwesterly flow aloft. A shortwave
trough will spread east-southeastward over the Pacific Northwest and
northern Rockies, while an additional clipper-type system influences
the Upper Midwest and Great Lakes. In both cases, thermodynamic
profiles are unlikely to be supportive of thunderstorms with this
shallow convection.
