Concerning...Severe potential...Watch unlikely Valid 181822Z - 181945Z Probability of Watch Issuance...5 percent SUMMARY...Isolated damaging wind gusts are possible this afternoon/evening. DISCUSSION...Thunderstorms are starting to develop across the Ozarks from western Arkansas into south-central Missouri. These storms are forming within an environment with somewhat more favorable mid-level lapse rates (~7 C/km per SGF/LZK 12Z RAOB) and hot temperatures near 100 degrees. Weak shear (10 knots or less through the entire troposphere) will limit storm organization. Despite the unorganized nature of the convection, strong heating/instability will support stronger storms capable of isolated microbursts and wind damage. A severe thunderstorm watch will not be issued for this sporadic/isolated threat. ..Bentley/Mosier.. 08/18/2025 ...Please see www.spc.noaa.gov for graphic product...
