...NO THUNDERSTORM AREAS FORECAST...

Day 2 Convective Outlook
NWS Storm Prediction Center Norman OK
1118 AM CST Thu Jan 23 2025
Valid 241200Z - 251200Z
...NO THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Thunderstorms are not forecast for Friday.
...Synopsis...
An upper trough from the Great Lakes to the western Gulf will shift
east, moving offshore the Atlantic coast by Saturday morning.
Meanwhile, low-amplitude westerly flow will emerge east of the
Rockies in the wake of the upper trough as another trough begins to
dig across the western U.S. late in the period. At the surface, high
pressure over the eastern U.S., and across the northern Rockies,
will maintain a dry and stable airmass, precluding thunderstorm
activity.

Day 3 Convective Outlook
NWS Storm Prediction Center Norman OK
0112 PM CST Thu Jan 23 2025
Valid 251200Z - 261200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe storms are not forecast for Saturday.
...Synopsis...
Upper ridging will build over the southern/central Rockies and
adjacent Plains as an upper trough continues to deepen across the
Pacific Coast vicinity. As this occurs, a surface low will move
across northern Mexico. Resulting south/southeasterly low-level flow
across the western Gulf will transport moisture northward across
portions of southern and southeastern TX. Within this warm advection
regime, weak elevated instability is expected to develop due to cool
temperatures aloft and steepening midlevel lapse rates. This should
be sufficient for isolated thunderstorms Saturday night/early Sunday
across southeast TX and portions of the Middle and Upper TX Coasts.
Severe thunderstorm potential appears low at this time given a lack
of surface-based instability.
