Day 1 Convective Outlook

0742 PM CDT Fri Sep 06 2024

Valid 070100Z - 071200Z

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

....SUMMARY...
Severe threat should be negligible the rest of tonight across the
Ohio Valley.

....01z Update...

Strong short-wave trough is digging southeast across the Great Lakes
early this evening. Large-scale ascent is spreading downstream ahead
of this feature, and this appears partly responsible for scattered
convection that developed along the associated cold front that
currently stretches from western NY-western PA-KY. Some of this
activity was briefly severe with gusts and some hail. However,
frontal convection is now spreading east of the primary instability
corridor where it will quickly encounter less favorable buoyancy.
Additionally, boundary-layer cooling will only lead to less
instability by mid evening. While gusty winds may continue with the
most robust storms for the next 1-2 hours, the overall severe threat
appears too limited to warrant MRGL risk overnight.
