Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0637 PM CST Fri Jan 23 2026
Valid 240100Z - 241200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Scattered weak thunderstorm activity is possible tonight primarily
across the Texas Big Bend region into central Texas.
...01z Update...
Broad warm advection regime has established itself across the
southern Plains into far west TX. Latest surface data suggests the
polar front has surged to a position from northwest of CLL-ATT-OZA.
This boundary will advance into the lower Rio Grande Valley region
later tonight. Earlier thoughts continue regarding the potential for
elevated convection atop the cooler air mass. Model guidance
continues to suggest some risk for surface-based convection near the
front later tonight. However, low-level convergence is not
particularly noteworthy and updraft strength with this activity is
expected to remain weak.
