0253 PM CDT Sun Aug 18 2024

Areas affected...central Arkansas...northern Mississippi

Concerning...Severe potential...Watch likely 

Valid 181953Z - 182100Z

Probability of Watch Issuance...80 percent

SUMMARY...Scattered strong to severe thunderstorms to increase in
coverage through the afternoon with potential for large hail and
damaging wind.

DISCUSSION...Thunderstorm development is likely across central
Arkansas into northern Mississippi over the next 1-2 hours as a cold
front sags south through time. The air mass ahead of the front is
characterized by as sharp MLCAPE gradient around 1000-3000 J/kg with
temperatures near 100 F and dew points in the low to mid 70s. A belt
of deep layer shear around 40-50 kts and the moist and unstable air
mass will support multicell clusters, capable of damaging wind and
instances of severe hail. A watch will likely be needed for portions
of this area to cover this threat soon.
