Mesoscale Discussion 0473

0153 AM CDT Mon Apr 10 2017
Areas affected...far northeast Kansas/northern Missouri/southeast
Iowa/northwest Illinois
Concerning...Severe Thunderstorm Watch 136...
Valid 100653Z - 100900Z
The severe weather threat for Severe Thunderstorm Watch 136
continues.
SUMMARY...Isolated strong/occasionally severe thunderstorms persist
across portions of the area in/near Severe Thunderstorm Watch #136.
DISCUSSION...A very slow/marginal decrease in storm intensity is
ongoing across the northern Missouri area per radar imagery over the
past hour, though some increase in convection is ongoing just
east/northeast of the watch across eastern Iowa and into northwest
Illinois. The storms are ongoing just ahead of the cold front
crossing eastern IA/eastern Kansas and nosing into northwest
Missouri, within an axis of around 1500 J/kg mixed-layer CAPE.
Aided by strong (50 to 60 kt) southwesterly flow around 1 km,
locally damaging winds will be possible locally, in addition to an
ongoing/marginally severe hail risk. While the most active
convection may continue to spread/develop east of the ongoing WW, a
new watch is not anticipated at this time given diminishing CAPE
with eastward extent into Illinois and continued/gradual
stabilization of the boundary layer.
