day 2 convective outlook
nws storm prediction center norman ok
1123 am cst fri dec 26 2025
valid 271200z - 281200z
...no severe thunderstorm areas forecast...
...summary...
severe storms are not expected on saturday or saturday night.
...synopsis...
mid-level ridging over the central us is forecast to weaken as
broader troughing over the west begins to move eastward. a
positive-tilt lead shortwave will move from the central rockies over
the plains, into the upper oh valley saturday and saturday night.
lift from this feature will deepen a surface low over the mo valley
allowing for some return moisture and an increase in low-level warm
advection saturday night. weak elevated buoyancy may develop and
support isolated thunderstorms ahead of the trough from eastern
ks/ok into the upper oh valley. severe potential appears limited
owing to mucape generally below 500 j/kg and the potential for any
stronger storms to mainly exist beyond 12z sunday (day 3).
