DISCUSSION...Latest Springfield, MO (KSGF) radar loop shows a band of severe/supercell storms moving across south-central Missouri and northwestern Arkansas. Meanwhile, convection is gradually increasing farther east, across western Tennessee. The airmass across this region remains very unstable, with mixed-layer CAPE in the 3000 to 4000 J/kg range. This should be more than sufficient to sustain vigorous updrafts, support CAM runs which increase convective coverage over the next several hours. Strong deep-layer winds will support organized convection, with an all-hazards severe risk likely to continue through the evening and into the overnight hours -- warranting new tornado watch issuance across this region. ..Goss/Hart.. 05/09/2024 ...Please see www.spc.noaa.gov for graphic product...
