Areas affected...Northern Kansas into southern Nebraska

Concerning...Severe Thunderstorm Watch 581...582...

Valid 100253Z - 100500Z

The severe weather threat for Severe Thunderstorm Watch 581, 582
continues.

SUMMARY...The potential for 60-80 mph winds may increase over the
next few hours across north-central Kansas and south-central
Nebraska.

DISCUSSION...KGLD reflectivity/velocity imagery continues to show
gradual upscale growth of a couple of convective clusters across
northwest KS and far southwest NE. This activity has a recent
history of producing 60-70 mph gusts, and while cold pool consolidation/organization remains a slow process, MRMS imagery
continues to show periodic upticks in convective intensity. This
trend should continue as this activity spreads east into a more
buoyant environment downstream where MLCAPE remains between
3000-4000 J/kg. Recent CAM solutions appear to be capturing recent
convective trends well and support this idea of further
intensification over the next 2-3 hours. These solutions also hint
at the potential for 60-80 mph winds, which appears reasonable based
on environmental buoyancy and wind shear (effective bulk shear on
the order of 40 knots). It remains uncertain how widespread such
winds will be given the slow upscale growth, but narrow corridors of
severe winds appear probable.
