Day 1 Convective Outlook  
NWS Storm Prediction Center Norman OK
0747 PM CDT Thu Aug 29 2024

Valid 300100Z - 301200Z

...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS THE UPPER
MIDWEST...

...SUMMARY...
Thunderstorms, a few severe, will spread across the Upper Midwest
this evening. Some risk for isolated wind/hail persists through
about 04-05z.

...01z Update...

Strong, well-defined upper low is lifting northeast across southern
MB early this evening. Trailing trough extends across the eastern
Dakotas with the southern most portion affecting western KS. This
feature is largely responsible for an elongated band of convection
across the Upper Midwest, arcing ahead of a synoptic front into the
central Plains. The most organized portion of this linear MCS is
advancing across western WI/southeast MN/IA. LLJ will shift east
across IA/WI this evening, suggesting this activity will remain
organized for several hours. Most supercell structures have been
disorganized along the line, and damaging winds will likely be the
primary severe threat, as large hail has been mostly absent with
this convection.

Scattered-numerous thunderstorm clusters persist across the Middle
Atlantic region this evening. 00z soundings from this region exhibit
modest lapse rates, but seasonally high PW values. Wind profiles are
marginally supportive of organized updrafts so this activity has
likely peaked in intensity. Aside from an isolated damaging
wind/hail report, the overall severe threat should gradually
diminish over the next few hours.
