Day 2 Convective Outlook
NWS Storm Prediction Center Norman OK
1257 AM CST Sun Jan 21 2024

Valid 221200Z - 231200Z

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

....SUMMARY...
Scattered thunderstorms are forecast to develop across parts of the
southern Plains, Ark-La-Tex and lower Mississippi Valley from Monday
into Monday night. Isolated thunderstorms may also develop along
parts of California and southwest Arizona. No severe threat is
expected across the continental United States.

....DISCUSSION...
Southwest mid-level flow will be in place on Monday from the Great
Plains to the Mississippi Valley, as an upper-level trough moves
into the southern Plains. In response, moisture advection associated
with a broad low-level jet, will take place across the Texas and
Louisiana coastal plains. Isolated thunderstorms may be ongoing at
the start of the period across parts of south and central Texas.
Convective coverage is expected to increase as a cluster of storms
moves eastward to near the Texas coast during the afternoon. The
storm cluster is forecast to move into southern Louisiana by the
late evening and overnight period. Instability should remain very
weak inland across the western Gulf Coast states suggesting that the
potential for organized storms will remain minimal. Elsewhere,
isolated thunderstorms will be possible across parts of California
and southwest Arizona as an upper-level trough approaches. No severe
threat is expected with this activity.
