...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM THE MIDWEST
TO THE ARK-LA-TEX...
...SUMMARY...
Scattered strong/severe thunderstorms will continue this evening
across portions of the Mid-Mississippi Valley/Midwest towards the
Ark-La-Tex. A few tornadoes, damaging winds, and large hail remain
possible.
...01z Update...
Well-defined upper low has progressed to near the MN/IA border early
this evening. Strongest mid-level height falls will spread across
the upper Great Lakes/Midwest region tonight which should encourage
eastward progression of surface front into lower MI-OH Valley-KY,
trailing southwest to near SHV by the end of the period. This
boundary has served as the primary mechanism for most of the robust
convection today and it is the demarcation for
severe/no-thunderstorms tonight. Ongoing pre-frontal convection is
currently located within the greatest instability axis from
IL-Arklatex. As this activity shifts about 100-150 miles downstream
it should encounter increasingly hostile conditions and the threat
for severe should gradually decrease. Until then, supercells may
pose a risk for all hazards within the SLIGHT Risk region.
