Day 2 Convective Outlook
NWS Storm Prediction Center Norman OK
1103 AM CST Sat Nov 27 2021
Valid 281200Z - 291200Z
...NO THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Thunderstorm chances will remain negligible on Sunday.
...Synopsis...
An amplified upper ridge will encompass the western half of the
CONUS while a large scale upper trough pivots across the eastern
half. An embedded upper low/shortwave trough will shift
east/southeast across the Great Lakes vicinity, bringing a strong
jet streak across the upper Ohio Valley during the late
afternoon/evening. Cold temperatures aloft with steep lapse rates
from near the surface through 700 mb will be in place, and shallow
convection with lake-effect snow bands is possible downstream from a
relatively warm Lake Erie. While a lightning flash could occur,
coverage will be less than 10% as instability will remain less than
100 J/kg MLCAPE through a shallow -15 C to -20 C layer. Elsewhere
across the country, dry and stable conditions will preclude
thunderstorm activity.
