Valid 270236Z - 270330Z The severe weather threat for Tornado Watch 324 continues. SUMMARY...A well-developed bow echo will approach the Louisville metro in the next hour. Significant damaging winds (75+ mph) are possible along with QLCS tornadoes. DISCUSSION...The ongoing MCS over portions of the lower OH Valley has continued to intensify this evening. The northern most segment of the line has shown indications of a surging rear-inflow jet across southwestern IN. Observed 70-80 kt velocities at 2-3km ARL on the KVWX VAD lend high confidence to significant damaging wind potential with the apex of this bow over the next 1-2 hours. Experimental WOFS guidance also lends high confidence to strong damaging wind potential with this feature. With an estimated forward speed of 45-50 kt, damaging winds (some 75+ mph) will approach the Louisville metro and southern IN within the next hour. QLCS tornadoes are also possible given large low-level ESRH of 300-400 m2/s2. ..Lyons.. 05/27/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...LMK...IND...PAH...
