Valid 302036Z - 302200Z The severe weather threat for Severe Thunderstorm Watch 568 continues. SUMMARY...Isolated cells may produce sporadic large hail to around 1.5 inches in diameter over the next couple of hours. Local extensions of WW 568 are possible. DISCUSSION...A band of supercells has persisted across southeast IA in a modest warm advection regime atop a capped boundary-layer. Moderate instability exists downstream, along with favorable vertical shear. However, multiple rounds of convection have impacted parts of the area in the past 12 hours. This will likely preclude upscale development, though some hail and gusty wind risk may linger for a couple more hours. WW 568 is set to expire at 21z, though local watch extensions are possible. ..Leitman.. 07/30/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...ILX...LSX...DVN...DMX...EAX...
