Day 2 Convective Outlook
NWS Storm Prediction Center Norman OK
1056 AM CST Tue Jan 09 2024

Valid 101200Z - 111200Z

....NO SEVERE THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Severe thunderstorms are not expected on Wednesday.

....Synopsis...
A strong mid/upper-level trough and related deep cyclone are
forecast to move quickly into eastern Canada and the western
Atlantic early in the forecast period. Weak convection may be
ongoing at the start of the period near Cape Cod and the coast of
Maine, but instability appears too weak to support lightning
potential before convection moves offshore.

Otherwise, a large upper trough will remain over most of the CONUS,
with multiple embedded shortwaves moving through broad cyclonic
flow. One embedded shortwave may produce weak convection capable of
sporadic lightning flashes across parts of the Great Basin during
the afternoon/evening. Cold temperatures aloft (colder than -30C at
500 mb) may support shallow convection capable of occasional
lightning flashes near the Pacific Northwest coast.

Elsewhere across the CONUS, generally dry/stable conditions should
limit thunderstorm potential on Wednesday.
