Public Information Statement
National Weather Service Quad Cities IA IL
752 PM CDT Tue Apr 16 2024

A fragmented line of storms near and just east of the 
immediate Mississippi River Valley continues on the remnants
of what was the dryline. The main threats are wind surges at 
the leading edge of any convective features from 
a combination of precipitation loading and well-organized storm 
structures (due to effective shear of around 60 kt).
Mid-level lapse rates have been chewed up from earlier, so
CAPE profiles have likely narrowed some resulting in somewhat
less deep convection. Still ample moisture, low-level
kinematics, and 50-100 J/kg of low-level CAPE for at least 
some tornado threat where any mesovortexgenesis can occur in 
well-aligned storm segments to the low-level shear. This tornado 
threat is likely to very gradually ease.

The overall severe threat should creep eastward through ~9:30-11 PM. There
is potential for redeveloping isolated storms even behind this axis
overnight as forcing for ascent from the main upper low and ahead of
the surface cold front shifts eastward.
