The magnitude of the hail threat should remain too small for weather watch issuance. DISCUSSION...The latest water vapor imagery shows a patch of maximized mid-level moisture associated with a shortwave trough, located across the Ohio and Tennessee Valleys. Scattered thunderstorms are ongoing with this area ahead of the shortwave trough over far southern Indiana, central Kentucky and middle Tennessee. Mesoscale analysis in central Kentucky has MUCAPE approaching 1000 J/kg, with 700-500 mb lapse rates in the 7 to 7.5 C/km range. In addition, RAP forecast soundings in central Kentucky have a steep temperature inversion from the surface to 850 mb, with effective shear near 50 knots. This suggests some potential for a couple elevated rotating storms capable of marginally severe hail. The threat should continue into the mid to late morning as scattered strong thunderstorms move eastward into eastern Kentucky. ..Broyles/Goss.. 02/27/2024 ...Please see www.spc.noaa.gov for graphic product...
