Day 4-8 Convective Outlook
NWS Storm Prediction Center Norman OK
0306 AM CST Mon Dec 26 2022

Valid 291200Z - 031200Z

....DISCUSSION...
Models during the extended period continue to show a large-scale
pattern more conducive for thunderstorm activity and some potential
for severe weather.  Differences are noted in models for Thursday
and Friday in the evolution of ejecting disturbances into the
central U.S.  During the early half of the extended period,
low-level moisture is expected to return northward from the Gulf
into the Arklatex and lower MS Valley.  Model variability between
the operational 26/00z GFS and ECMWF is not grossly high but
confidence in placing potential severe areas remains sufficiently
low at this time, especially for the Friday-Monday period.  Models
are beginning to suggest next Monday (day 8) may need to be a day of
focus for severe weather potential compared to other previous days.
