Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0650 PM CST Sun Dec 26 2021
Valid 270100Z - 271200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Isolated thunderstorms remain possible tonight over parts of the
Midwest.
...01z Update...
A warm front, extending from northeast KS southeast to along the
TN/KY border at 01z, will lift steadily north overnight as a surface
low over northern KS moves east into northern IL by 12z.
Strengthening low-level warm advection will develop in response to
the development of a 50-60 kt low-level jet, providing large-scale
ascent within a weakly unstable air mass characterized by MUCAPE of
300-700 J/kg. lightning has recently been detected over central IA,
northeast MO and south-central MN, and thunderstorms are expected to
gradually expand/move east into the OH Valley during the overnight
time frame. Small hail may accompany a couple of the stronger
storms owing to steepening mid-level lapse rates, however severe
weather is not expected.
