Day 1 Convective Outlook

Valid 100100Z - 101200Z
...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS THE MID
MISSOURI VALLEY...
...SUMMARY...
Scattered severe thunderstorms will continue for the next several
hours across the mid Missouri Valley region. Other more isolated
strong storms remain possible tonight across portions of the mid
Mississippi/Ohio Valley as well as parts of the lower Mississippi
Valley and south Texas.
...01z Update...
Strongly dynamic, and focused zone of forcing for ascent is
spreading across the mid MO Valley early this evening. Exit region
of 500mb speed max should translate across southeast NE along the
IA/MO border by 10/12z. A narrow corridor of strong instability
extends ahead of the surface low from central MO into southeast NE.
Supercell threat remains concentrated and focused immediately ahead
of the surface low where notable buoyancy remains. This activity
should wane later this evening as it encounters less favorable
environment downstream.
Remnants of Cristobal are lifting quickly across WI/lower MI as
strong LLJ shifts into the central Great Lakes region. While wind
profiles remain supportive of supercells, poor lapse rates and
limited instability should preclude more than isolated damaging wind
report, or perhaps a brief tornado.
Storms have struggled to develop along the wind shift across the
Arklatex due to weak forcing. This activity is largely driven by
surface heating and with diurnal cooling about to commence, it
appears this convection should remain mostly sub-severe.
Clusters of deep convection have organized west of the lower Rio
Grande Valley over the higher terrain. Isolated severe may yet
evolve east of the river as the surface front settles into this
region.
