Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0628 PM CST Sun Jan 25 2026
Valid 260100Z - 261200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe thunderstorms are not forecast tonight.
...01z Update...
Strong 500mb speed max is translating across WV early this evening.
As a result, primary corridor of warm advection is now focusing
across the Middle Atlantic/southern New England where negligible
buoyancy is noted. Deep convection has been confined to the trailing
cold front across portions of the Southeast, and lightning with this
activity has been decreasing over the last few hours. While 00z
sounding from JAX exhibits around 300 J/kg MLCAPE, low-level
convergence will gradually focus off the Atlantic coast later this
evening as the front surges across this region. Given the limited
instability, and the primary focus for ascent well north of this
region, severe probabilities appear low the rest of tonight.
