Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
1002 AM CST Sun Dec 26 2021
Valid 261630Z - 271200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Isolated thunderstorms are possible today over parts of the Pacific
Coast States, eastern Great Basin to central Rockies, and parts of
the Midwest.
...Pacific Northwest and Great Basin...
Strong onshore flow and cold temperatures aloft are present once
again today along the OR and northern CA coast. This will maintain
the risk of isolated lightning flashes through the forecast period
in this region. A few instances of lightning will also be possible
in snow showers ahead of a cold front surging eastward across parts
of UT/CO/WY.
...MS/OH Valleys...
Low-level warm advection and lift is expected to intensify late this
afternoon and early evening over parts of IA/MO/IL, resulting in
isolated showers and thunderstorms. The strongest cells in this
initial activity could produce small hail, but no severe storms are
anticipated. Scattered thunderstorms will likely persist through
the night and spread eastward into parts of IN/OH and Lower MI by
Monday morning.
