Day 1 Convective Outlook 
NWS Storm Prediction Center Norman OK
0812 PM CDT Mon Jul 29 2024

Valid 300100Z - 301200Z

...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FOR PARTS OF THE
CENTRAL/NORTHERN PLAINS...AND ALSO FROM CENTRAL/SOUTHERN LL/IN INTO
SOUTHWEST OH AND MUCH OF KY...

...SUMMARY...
Severe storms capable of large hail and wind gusts of 60-80 mph
remain possible tonight across parts of the central and northern
Plains. Another area of severe storms, with potential for damaging
wind, isolated hail, and a couple of tornadoes, will affect portions
of central/southern Illinois and Indiana into Kentucky tonight.

...Central/northern Plains...
One intense thunderstorm cluster has evolved this evening across
south-central SD, with another developing across northern
SD/southern ND. Moderate to strong buoyancy and effective shear of
30-40 kt (as noted on 00Z regional soundings) will continue to
support organized severe-thunderstorm potential. Any remaining
discrete cells will continue to pose a threat of large hail, while
the developing storm clusters could pose an increasing threat of
severe gusts (potentially greater than 75 mph) through the evening.
The Slight Risk has been expanded south and east to cover the
potential severe-wind threat into late tonight. See MCD 1732 for
more information regarding the threat across parts of southeast SD
into eastern NE and western IA.

...IL/IN/KY vicinity...
Robust storms are beginning to develop across parts of central IL/IN
this evening, within an environment characterized by very rich
low-level moisture, strong buoyancy, and moderate northwesterly
deep-layer shear. Initial discrete development could pose a threat
of hail and a couple of tornadoes, with some increase in low-level
shear expected through the evening. Eventually, an upscale-growing
cluster may develop and move southeastward, with an increasing
damaging-wind threat into parts of KY.

...GA...
A few stronger southward-moving storm clusters persist this evening
across parts of western/central GA. These could continue to pose a
short-term threat of damaging wind, before an expected weakening
trend later tonight.
