Day 4-8 Convective Outlook
NWS Storm Prediction Center Norman OK
0352 AM CDT Fri Jul 07 2023

Valid 101200Z - 151200Z

....DISCUSSION...
Global models remain fairly consistent with respect to large-scale
pattern evolution, with an upper low forecast to linger over the
northern Ontario/Hudson Bay vicinity through the period.  As a
result, a persistent zone of enhanced west-northwesterly flow aloft
will remain over the central U.S./Plains region.

As a short-wave trough shifts toward/off the East Coast Day 4, focus
for severe weather will again shift westward to the High
Plains/Plains, where the most persistently favorable combination of
CAPE and shear should reside.  However, highlighting specific areas
of more concentrated risk remains quite difficult -- modulated to
some degree by prior convective events.  As such, no risk areas will
be highlighted at this time.
