Day 3 Convective Outlook
NWS Storm Prediction Center Norman OK
0127 AM CST Sat Feb 11 2023

Valid 131200Z - 141200Z

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

....SUMMARY...
Organized severe thunderstorms are not forecast on Monday across the
contiguous United States.

....Synopsis...
A mid-level low initially along the AZ/Sonora border will move
east-northeast to the NM/OK/TX border by early Tuesday morning.  An
upstream mid-level trough will dig southward along the Pacific
Northwest coastline.  Surface high pressure initially over much of
the central US and the Gulf basin will quickly weaken during the
day.  A lee trough is forecast to develop over the southern High
Plains late in the day in response to the approaching mid-level
feature, before a deepening cyclone evolves over eastern CO early
Tuesday.  The early stage of moisture return from the western Gulf
into the southern Great Plains will occur.  Limited low-level
moisture featuring 50s surface dewpoints will overspread the coastal
plain and eventually into parts of central and north TX late Monday
night.  Isolated to widely scattered thunderstorms will probably
develop Monday night across parts of the southern Great Plains
within strengthening warm-air advection, but weak instability will
likely preclude a low severe risk.
