MD 1836 CONCERNING TORNADO WATCH 600... FOR NORTHEASTERN IOWA/SOUTHWESTERN WISCONSIN
Mesoscale Discussion 1836 NWS Storm Prediction Center Norman OK 1125 PM CDT Mon Aug 05 2024 Areas affected...northeastern Iowa/southwestern Wisconsin Concerning...Tornado Watch 600... Valid 060425Z - 060500Z The severe weather threat for Tornado Watch 600 continues. SUMMARY...Tornado risk across the remainder of WW 600 will continue to diminish as storms move eastward/out of the watch. New WW will not be required. DISCUSSION...Latest radar loop shows the strongest storms within the ongoing cluster now moving across southwestern Wisconsin/into WW 601. While a favorable airmass persists near the Mississippi River Valley, storms across northeastern Iowa have remained generally sub-severe, and expect them to largely remain so. As such, it appears reasonable to allow WW 600 to expire as scheduled at 06/05Z. ..Goss.. 08/06/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...MKX...DVN...ARX...

MD 1835 CONCERNING TORNADO WATCH 599... FOR COASTAL SOUTHEASTERN SOUTH CAROLINA
Mesoscale Discussion 1835 NWS Storm Prediction Center Norman OK 1035 PM CDT Mon Aug 05 2024 Areas affected...coastal southeastern South Carolina Concerning...Tornado Watch 599... Valid 060335Z - 060500Z The severe weather threat for Tornado Watch 599 continues. SUMMARY...Tornado risk continues in the northeastern quadrant of Debby, as the center of the storm lingers over southeastern Georgia. With Tornado Watch 599 set to expire at 06/05Z, a new WW will likely be required. DISCUSSION...Latest radar loop continues to show cellular convection within a persistent band situated within the northeastern quadrant of Debby's circulation. Stronger offshore cells continue to exhibit compact/occasionally strong circulations, with a couple of tornadoes reported onshore over the past 1 to 2 hours. At this time, it appears that this trend may continue, extending beyond the scheduled expiration of the existing Tornado Watch (599). Given the persistence of a moist/low-CAPE environment combined with very strong low-level shear (weakly veering flow with height, increasing rapidly to 50 kt at around 800m AGL), which should support a continued tornado risk locally, a new watch will likely be required, to cover the ongoing threat. ..Goss.. 08/06/2024 ...Please see www.spc.noaa.gov for graphic product...
